Useful Hints >
Useful Hints
In this chapter some information is given about the default settings of MAYAH
codecs, which may be useful for proper operation of the Web Remote.
2.1
Default IP settings
a) By default every MAYAH Codec has got the following IP settings:
· DHCP: off
· Address: 10.0.0.10
· Netmask: 255.255.255.0
· Gateway: 255.255.255.255
· DNS Server: 255.255.255.255
Advanced Dual IP Audio Codec C10/C12 and Centauri IV by default have got two
Ethernet cards with different default settings.
· LAN (basic, by default only used for remote control)
- DHCP: off
- Address: 10.0.0.10
- Netmask: 255.255.255.0
- Gateway: 255.255.255.255
- DNS Server: 255.255.255.255
· LAN1 (additional, by default only used for audio streaming)
- DHCP: off
- Address: 10.0.1.10
- Netmask: 255.255.255.0
- Gateway: 255.255.255.255
- DNS Server: 255.255.255.255
Note:
If IP-address 255.255.255.255 is entered, it means that the service or address is
not in use.
Note 2:
If you want to control your MAYAH Codec in your LAN it must be located in the
same subnet as your PC i.e. when the digits of your binary net mask are '1' the
referring digits of the IP address of your MAYAH Codec and your PC must be the
same.
Example:
Net mask: 255.255.255.0 = 11111111 11111111 11111111 00000000
PC IP address: 192.168.1.56
MAYAH Codec with IP address: 192.168.1.57 is located in the same subnet, but
192.168.100.57 is not.
b) Default IP ports on MAYAH devices
Necessary IP ports for successful Audio-over-IP connections:
· 5004 (Audio transmission, RTP)
· 5005 (Network information, RTCP)
Webremote 4 Manual
Useful Hints > Default IP settings
·
11
5060 (SIP)
Some other IP ports used by MAYAH devices:
· 20 and 21 (FTP Data and control)
· 23 (Telnet remote control)
· 80 (HTTP for web-remote)
· 123 (NTP)
· 161 (SNMP control)
· 162 (SNMP traps)
· 5006 (FEC Redundant Data, columns)
· 5008 (FEC Redundant Data, rows)
· 2060 (Audio level information for remote control software)
· 2061 (UDP scan)
Full list of the IP ports can be found in the Communication Reference Manual at
www.mayah.com
2.2
How to access MAYAH codec via FTP
Each MAYAH unit provides an integrated FTP and Web server, so you can
access them as soon as the device is reachable via IP and the IP address is
known.
FTP access should be performed only by an experienced user
a) Access MAYAH Codec system files
FTP access data for MAYAH Codec are by default:
· Host: <IP addres of MAYAH Codec>
· Username: Admin
· Password: Power
b) Access storage devices attached to MAYAH Codec
To access SD Card or USB stick inserted into MAYAH Codec just add an
appropriate 'path' to the access data:
· D: (SD Card); E: (PC card); F: (USB storage)
2.3
How to update MAYAH codec firmware
In some cases it can be necessary to update your MAYAH Codec. With current
Audio Codec generation It can be done using the Web Remote, USB stick or an
SD card or using FTP. The update process should not be interrupted, otherwise
the unit can be damaged.
The firmware update is provided by MAYAH as a single file with the file name
extension '.upd'. This file must be get ready on your computer before update.
Webremote 4 Manual

Rename the file to "device.upd"
Put the file on a USB stick in the folder \Update\
Turn off your MAYAH Codec
Put the USB Stick in the corresponding slot on the device
Turn on the MAYAH Codec
Don't disconnect the update media from the device if "Update
Extracting files" appears on an LCD screen or ALARM, CONNECT
and FRAMED LEDs are lit up simultaneously!
If the "device.upd" file is not write-protected it will be deleted from the
storage media upon successful update
If the file is write-protected it may come to an Update "loop", so
please remove the storage media from device as soon as the LCD
screen shows "Update ... %" or LEDs are have started to blink.
c) Update by using FTP (recommended)
·
·

Installation. The new firmware is installed automatically. The
progress is shown by the text messages at the LCD screen and/
or blinking of LEDs. After this step is completed successfully
another reboot will occur automatically.
First start of the new firmware. At this point some further
update processes might occur without notice. These processes
must not be interrupted. On MAYAH Codec models without LCD
screen please allow at least 1 minute of normal operation (green
LED is on and not blinking) after the update. DO NOT SWITCH
THE MAYAH Codec OFF.
Update finished. To make sure that all update processes are
completed on MAYAH Codec without LCD screen, please ensure
that the unit is reachable via network. On units with LCD screen it
is enough to wait until the Start Screen is displayed.
How to activate Keycodes
Keycodes are used to activate optional algorithms (see also 'SETUP/Profiles')
and functions of MAYAH Codec. Keycodes are provided by MAYAH
Communications.
Keycodes can be set for each particular device by using Web Remote (menu
item 'SPECIAL/Keycodes').
Alternatively keycodes can be entered with the direct command 'sys_keycode
<keycode>' by using Telnet session, boot script (see below) or any other control
type.
2.5
How to reset MAYAH codec
This operation should only be done by expert users. MAYAH is not
responsible for any possible risks or configuration losses in case of
misuse of this function.
Upon factory reset the entire configuration of the device will be set
back to the factory default values. Codec quality profiles, phone book
entries and all presets created by device users will be deleted!
There are three ways to bring the MAYAH Codec back to the factory defaults
a) For MAYAH Codec models with the front panel controls it is possible to do in
the menu 'SYSTEM/MISC/Factory Default'.
b) For all models it is possible to do in the menu 'SPECIAL/Reset' of the Web
Remote Control.
Webremote 4 Manual
14
Useful Hints > How to reset MAYAH codec
c) For all models it is possible to do by establishing a telnet session to the
MAYAH Codec or by using a telnet console in the SPECIAL area of the
integrated web-remote and typing the direct command 'sys_reset factory'.
d) For all models it is possible to include the direct command 'sys_reset factory' in
the Boot Script file and apply the boot script as described in the next chapter of
this manual.
2.6
Boot Script
This feature should only be used by expert users for emergency
situations e.g. helpful emergency USB stick created by service staff
to support non technical colleagues.
This configuration method can be particularly useful for all MAYAH Codec models
without front panel controls in case that access data have been lost or device has
become unreachable via IP.
A file named 'mayah-command-scripts.txt' can be used as a boot script if it is
located in the root folder of a USB stick. A boot script can contain a set of any
direct commands (one command per line). Such direct commands are described
in the Communication Reference Manual. Please contact MAYAH for more
information on this.
Just insert the USB stick and start device. All the direct commands will be
executed after booting.
Example mayah-command-scripts.txt
ip_address 192.168.1.57
ip_netmask 255.255.255.0
Description: This simple boot script sets the IP address of MAYAH Codec to
'192.168.1.57' and the net mask to '255.255.255.0'.

Recorder
Recorder menu is only available on devices which support this functionality. It
allows to control most of the recording operations and with the current firmware
some basic playback operations.
·
·
·
Usually no recording / playback operations are possible if the
device is already operating in the Dual Mode.
Recording during live transmission or Playback during live
transmission can only be done with uncompressed Linear (.WAV)
files.
In most cases only the same sample rate on recording/playback
and live transmission operation can be used.
3.5.4.1 Record
In this menu settings and controls for recording can be found.
Meaning of the control buttons on the right:
·
·
·
·
Record: starts the recording
Pause: recording is being stopped but can be resumed within the same file
Stop: stops the recording and finalizes the recorded file on the storage medium
Default Record: records a single file with a specific name, which can be then
played back in the 'RECORDER/PLAY' menu.
Webremote 4 Manual
32
Please note that all changes are saved only when 'RECORD'
button is clicked.
Typical (default) view of Recorder menu
a) Select Record Quality
allows to select one of the existing codec profiles for recording.
b) Select Record Medium
allows to select one of the available storage devices, e.g. SD Card, USB flash
memory stick, PC Card etc.
c) File Chunk Size (seconds)
Here the duration limit of recorded files can be set (in seconds).
· It means when the limit is reached during recording, the audio file is saved
and the recording continues automatically to the next new file.
· If "0" is set then no duration limit is applied. Recording will continue until the
file size limit of a file system is reached (usually, 2GB or 4GB for FAT or
FAT32 correspondingly), in such case a new file will be created automatically
and the recording will continue until storage media is full.
d) Record File Name
Here the file name structure of recorded audio files (tracks) can be modified by
using time and date variables.
File name variables:
·
·
·
·
/year Specifies the current year (4 digits)
/yrsh Specifies the current year (2 digits)
/mon Specifies the current month; January = 1, February = 2, and so on (2
digits)
/day Specifies the current day of the month (2 digits)
Webremote 4 Manual
·
·
·
·
·
33
/dow Specifies the current day of the week; Sunday = 0, Monday = 1, and so
on (1 digit)
/hour Specifies the current hour (2 digits)
/min Specifies the current minute (2 digits)
/sec Specifies the current second (2 digits)
/ms Specifies the current millisecond (3 digits)
Any additional combination of symbols can be used at any place before, between
or after variables
Filename extension is set automatically according to the format of the recording!
Example:
mayah_/yrsh/mon/day_/hour-/min-/sec
when using "Linear" as recording format it will result in a following file name:
'mayah_110921_15-05-20.wav'
·
·
·
·
·
If 'REC seconds' (item 'a' in this chapter) is set to '0' and no
variables are configured under 'REC Name' then the files are
named as "T01", "T02" and so on till "T99"
If 'REC seconds' is set to other value than '0' but still no
variables are configured under 'REC Name' then the files are
named with a default combination of variables:
'/year/mon/day-/hour/min/sec', e.g. resulting in the name
'20120105-143606.wav'
To avoid overwriting of files when recording stops and starts
again quickly it is strongly recommended always to use '/sec' or
depending on application even '/ms' variables when the file name
pattern is configured manually
For correct naming of the files with the time & date variables the
system time must be properly configured on the MAYAH Codec.
If there's an internet access available it is recommended also to
setup the NTP function by using Web Remote. (See Web Remote
Menu 'SETUP/NTP')
e) Record Folder
Allows to define a directory (folder) name on the selected storage device where
the recorded files will be written to.
Default folder name is 'TRACKS'.
Please note when operated via Front Panel, MAYAH Codec can only
read the files for playback or Upload from the default folder

file will be attempted by the MAYAH Codec according to the ftp settings in the
following fields.
· MAYAH Codec will attempt to upload each recorded file
immediately after it's finalized on the storage media.
· With current firmware version only one attempt is being done.
g) Delete files after upload
Activates an automatic deletion of successfully uploaded files.
· If file upload process is interrupted or an FTP access attempt
fails, the file remains on the storage media.
· With current firmware version only one upload attempt is being
done.
h) Host
Here a URL(plain text address) or IP-address of the FTP upload server must be

k) Target directory (path)
Enter desired path at the FTP upload server, e.g. 'MAYAH Codec /' (without
quotes). No path means that the files will be uploaded to the root directory of the
FTP account.
If file with the same name is already available on the remote FTP
server/path, it will be overwritten without further notice.
l) FTP Client
Here can be set if FTP client of the MAYAH Codec must use passive or active
FTP. Passive is more universal but for some applications it is necessary to
change this setting.
m) Interface
Here can be set which interface will be used for the next upload (default: LAN-1/
Ethernet). If any further IP-based interface like 3G or WLAN are currently
available on the MAYAH Codec it can be selected to do the upload.

see below). The maximum value is 1536 bytes.
It is recommended to leave the packet size at its default value "1".
This value means that the RFC conform packet size is chosen
automatically for each audio coding algorithm. It helps to reach the
minimum IP overhead and at particular transmission types it also may

i) Delay
- sets the size of the receive buffer in ms.
Max. possible value 5000 ms.
·
·
RTP packets can be resorted if they are received in the wrong
order. The higher the value is, the more packets can be resorted.
Generally receive buffer value should be bigger than average
network jitter (see Codec/Status/Interface)
If AJC is activated the bigger delay value will be applied (see
System/Misc/AJC)
j) Transferrate (Mbps)
- sets the transfer rate (Speed) for the corresponding network interface, to either:
· Auto (i.e. auto-sensing the network data rate)

3.5.6.5 ISDN
Here the settings for the internal ISDN S0 interfaces of MAYAH Codec can be
done.
a) Protocol
This item enables to select the D-channel protocol to:
· DSS1 (Europe)
Webremote 4 Manual
64
·
·
·
·
·
NI1 (North America)
5ESS (North America)
Jate (Japan)
VN (obsolete French national protocol; usually replaced by DSS1)
AUSTEL (obsolete Australian national protocol; usually replaced by DSS1)
Furthermore this item enables to set:
b) Active layer 1 mode
- determines whether ISDN Layer 1 stays active all the time, or not.
When MAYAH Codec is used in the Netherlands, this value should definitely be
set to ON.
c) Answer time
- defines the ‘telegram’ interval (used in ISDN connections) - in milliseconds. The
called MAYAH codec sends out its ‘telegram’ 10 times till the ISDN answer delay
expires. The default value is 5,000 ms.
d) PBX (=Private Branch Exchange)
When MAYAH Codec is connected to a PBX or ISDN switch, it is often necessary
to add a number for external access (e.g. 9).
e) PBX digits
PBX digits determines the number of digits BEFORE the 'additional preceding
PBX number' becomes valid.
For example:
- PBX:
9
- PBX digits :
5
Entered number: 1234
Dialed number: 1234
Entered number: 01234 Dialed number: 901234
f) Predial
Sometimes it is necessary to use a special provider to guarantee the quality of
the ISDN service or the carriage of ISDN calls through a Gateway. Usually a
special provider can be selected by dialing a special call-by-call number before
the normal number.
This Predial Number precedes EVERY dialled number (Direct dial or Phone
book).
g) MSN (= Multiple Subscriber Number)
Here the MSN (D-channel protocol DSS1 or VN4) or the ID (all other D-channel
protocols) is entered.
The most common reason to use MSN are:
· Multiple ISDN devices using the same ISDN service uses one ISDN bus (e.g.
MAYAH Codec and telephone are connected to the same ISDN bus)
· MAYAH Codec is connected to a PBX (=Private Branch Exchange)
Webremote 4 Manual
·
·
·
65
If a MAYAH Codec is connected directly to an ISDN DSS1 S0
bus and no other device shares this ISDN bus then no MSN's
must be entered. 'Directly' means that no PBX is used.
At D-channel protocols NI1 and 5ESS an ID must be assigned for
every B-channel. Often the last 4 digits of the ISDN number must
be entered as ID number
MSN/ID cannot be longer than the local ISDN number (no country
or area codes should be used).
h) SPID (=Service Profile Identifier)
SPID's are only in use with the D-channel protocol NI1 and 5ESS in North
America. At these two protocols it is mandatory to assign every B-channel a
separate SPID.
Please ask the local ISDN provider for further details.
i) Redials
Defines the number of Redials which will be attempted. A redial will occur if the
other party cannot be reached either through being busy, if there’s no response,
or if the other party disconnects/drops the call.
j) Redial wait
sets the interval time between the redial attempts (in seconds).
k) G.711
North America/Japan and Europe use a different coding method for ISDN
telephony. Thus, the following alternatives are available:
· A-law (as used in Europe – uses non linear PCM, with 13 segments)
· µ-law (as used in USA and Japan – also non-linear PCM; but 15 segments)
If G.711 law is not set properly then strong disturbances occurs at
G.711 transmissions.
l) G.711 attenuation
Sometimes G.711 signals (i.e. normal telephone signals) are overmodulated and
their high audio levels can cause distortions. Therefore G.711 attenuation can be
set to:
· 0 dB (no attenuation, default)
· 6 dB
· 12 dB
m) G.711 ISDN service
Here the service used for G.711 calls are set. It can be selected between
· Speech (default and standard)
and
· Telephony
n) Call prefix
Here the Call prefix can be set for national and international calls

3.5.6.6 POTS
Here the settings can be done for MAYAH POTS card (optional).
Due to the usually very limited bandwidth at POTS connections the
most efficient MPEG-4 HE-AACv2 (AAC HE) stereo is used by
MAYAH Codec, no matter which Codec Quality has been chosen
previously. MAYAH Codec evaluates the quality of current
connection and adjusts the bit rate automatically.
a) PBX (=Private Branch Exchange)
When MAYAH Codec is connected to a PBX switch, it is often necessary to add a
number for external access (e.g. 9).
b) PBX digits
PBX digits determines the number of digits BEFORE the 'additional preceding
PBX number' is preceded.
For example:
- PBX:
9
- PBX digits :
5
Entered number: 1234
Dialed number: 1234
Entered number: 01234 Dialed number: 901234
b) Predial
Sometimes it is necessary to use a special provider to guarantee the quality of
the service or the carriage of telephone calls through a Gateway. Usually a
special provider can be selected by dialing a special call-by-call number before
the normal number.
This Predial Number precedes EVERY dialled number (Direct dial or Phone
book).
Webremote 4 Manual
67
c) Redials
Defines the number of Redials which will be attempted. A redial will occur if the
other party cannot be reached either through being busy, if there’s no response,
or if the other party disconnects/drops the call.
d) Redial wait
sets the interval time between the redial attempts (in seconds).
e) Answer time
Time (in ms) between connection is established and start of encoding (i.e.
sending of audio data). By default this value is set to 1,000 ms (Range is 100 to
5,000 ms).
f) Audio Delay
Sets the size of the receive buffer in ms.
This value should be set before transmission. In contrary with the
IP-based transmission it is impossible to apply any buffer changes
during the running connection.
3.5.6.7 SIP
Here the settings for SIP communication over SIP Server can be done.
Additionally the STUN server can be entered here. Direct SIP connections to the
known public IP addresses can be realised without these settings.
a) Stun Server
A STUN server (Simple Transversal of UDP Through NATs) is necessary that a
client behind a NAT or NATs can find its public IP address. NAT stands for
Network Address Translation.

3.5.6.11 AJC
The feature AJC (= Automatic Jitter Compensation) provides an automatic
adaptation of the IP transmission to network capabilities when using the
interfaces Ethernet, 3G/4G or WLAN.The AJC optimizes the following
parameters at:
a) Encoder side:
The information provided by the peer via RTCP is used for evaluating the network
capabilities. If applicable the packet size is increased first, to improve the
transmission (a bigger packet size results in less IP overhead). If increasing
packet size does not lead to satisfactory results then the encoder bit rate will be
reduced automatically.
· Mode: AJC can be selected to
- auto: AJC is enabled
- off: AJC is disabled
- default: AJC is reset to factory default
(In this version: default = auto)
· Time (s): Set evaluation time in seconds (by default 30 seconds)
b) Decoder side
If necessary the audio delay is increased to adapt the transmission to a current
network conditions. Increasing the audio delay is
achieved by increasing the receive buffer for incoming IP packets.
· Mode: AJC can be selected to
- default: AJC is reset to factory default
- auto: AJC is enabled
- off: AJC is disabled
- NTP (optional, required for synchronized playout of the contents from a single
encoder on multiple decoders)
Webremote 4 Manual
73
(In this version: default = auto)
· Time (s): Set evaluation time in seconds (by default 30 seconds)
Please note that AJC on the decoder side will only add some
additional buffer if the audio delay value set up manually for any of
the IP network interfaces (e.g. Ethernet, 3G or WLAN) is smaller
than the jitter values measured during the given measurement
interval.
You can see if AJC is active on the right side of the Web Remote.

3.5.6.12 Applications
MAYAH Codec support several powerful enhanced applications:
· Dual mode ISDN (only Centauri IV and C12):
- allows two independent mono ISDN connections
· Dual mode IP (all devices)
- allows two independent mono IP connections
· Multipoint ISDN (only Centauri IV and C12)
· Intercom (optional):
- enables an additional IP connection to a pre-defined IP address besides the
main connection
· Backup (all devices)
· Gateway (all devices)
Webremote 4 Manual
74
Choose any of the desired / available enhanced Applications for your MAYAH
Codec from the drop-down menu on this page.
To deactivate the enhanced application mode choose "Normal".
Note
a) Activation of any Enhanced Application disables Recorder
functionality, and vice versa, if Recorder is currently active it is
impossible to activate an Enhanced Application.
b) Upon activation of certain Enhanced Applications the audio
channels of the mixer matrix usually assigned to Recorder are used
for audio routing of the enhanced application. If any changes
required in the audio routing / panning they can be stored for future
use in the menu Mixer/Profiles/Skins/
3.5.6.12.1 Intercom
In Intercom Mode besides the main connection a 'command connection', e.g. to
call for technician can be established additionally.
This 'command connection' has following limitations:
· it is an IP-based connection
· just G.711, G.722 or Linear coding algorithms are supported
The destination of an intercom connection can be defined in this menu.
When Intercom Mode is selected, the intercom connection can be established
and hung up by pressing '0' button for approx. 3 seconds.
Note:
Intercom mode is optional and can be activated by entering a key code to the
device. Contact MAYAH if you need this option.
3.5.6.12.2 Dual Mode ISDN
Dual Mode ISDN (Centauri IV and C12) enables two independent mono ISDN
connections.
By default the audio inputs and outputs of the left channel are used by the first
connection, whereas audio inputs and outputs of the right channel are used by
the second connection.
By default first connection is realised with the B-Channel 1 of the first ISDN S0
and the second connection with the B-Channel 2 of the first ISDN S0. However
you can choose any of the available B-Channels for the second connection to
start with.
Webremote 4 Manual
75
Currently there's a codec quality limitation of 64 kbit/s 32 kHz mono for Dual
Mode ISDN. This will be extended in future.
When Dual Mode ISDN is active, codec profiles can be applied separately for
connection 1 and connection 2.
Connections can be established and terminated independently using two
separate DIAL buttons.
Different MSN's should be assigned to the B-channels. This allows to
distinguish between the audio at incoming calls.
Example:
· English reporter at the analog input (L), MSN of first B-channel: 33
· Spanish reporter at the analog input (R), MSN of second B-channel: 34
Call +44 12345 33 to listen to the English voice, call +44 12345 34 to listen to the
Spanish voice.
It is possible to modify the default audio routing for Dual Mode to
achieve some advanced routing scenarios. However, this should only
be performed by an experienced user.
3.5.6.12.3 Dual Mode IP
Similarly to the Dual Mode ISDN the Dual Mode IP enables two independent bidirectional mono IP connections.
By default the audio inputs and outputs of the left channel are used by the first
connection, whereas audio inputs and outputs of the right channel are used by
the second connection.
By default first connection is realised on the IP Port 5004 and the second on the
IP Port 5014 (i.e. IP Port of the first connection + 10)
When Dual Mode IP is active, codec profiles can be applied separately for
connection 1 and connection 2.
Connections can be established and terminated independently using two
separate DIAL buttons.
3.5.6.13 BGAN
The Broadband Global Area Network (BGAN), is a global Satellite IP Network
using portable terminals.
MAYAH Codec is connected to a terminal via Ethernet interface, just like to any
Webremote 4 Manual
76
other Ethernet switch.
In this menu the BGAN mode can be activated or deactivated.
MAYAH Audio Codecs support the following terminals:
·
·
·
Thrane & Thrane: Explorer 500, 700
Addvalue Communications: Wideye Sabre 1, Wideye Sabre Ranger
Hughes Network Systems: 9201, 9250, 9350
Most BGAN Terminals are also DHCP Servers, so it is recommended to enable
the DHCP function on your
MAYAH Codec (see chapter SETUP/Ethernet).
For most BGAN Terminals and subscriptions the following
configuration options can be left empty, use them only if you know
what you are doing.
In this menu it is also possible to predefine the following parameters for a BGAN
connection:

3.5.6.14 FEC
Not all IP based connections are within trusted and well-managed networks.
Many times – especially when using public networks - like the Internet - IP
packets may be lost due to different causes.
Forward Error Correction (FEC) provides the possibility of error detection and/or
correction by adding redundant data streams. Thereby retransmission or
corruption of data can often be avoided at the cost of higher bandwidth needs
and increased delay.
The FEC algorithm used by MAYAH is described in the “Pro-MPEG Code of
Practice #3 release (www.prompeg.org) based on RFC 2733 (
www.ietf.org/rfc/rfc2733.txt).
FEC can be applied to all RTP-based connections by using any of the FEC
presets:
·
·
·
·
·
lowest delay: 50% overhead, up to 4 packets can be restored at the burst
loss
low delay: 20% overhead, up to 5 packets can be restored at the burst loss
middle delay: 25% overhead, up to 10 packets can be restored at the burst
loss
low bitrate: 5% overhead, up to 5 packets can be restored at the burst loss
high security: 25% overhead, due to the nature of the decoding scheme the
potential number of packets that can be recovered is much higher and
depending on the pattern of which packets were lost
·
You can always see if FEC will be applied to your next RTPbased connection with the 'LED' on the right side of the Web
Remote. See also Status Indicators.
Webremote 4 Manual

·
Further information on FEC can be found in the Application Note
31 on MAYAH's web site.
3.5.6.15 RS-232
On C10/C12 there's a dedicated serial interface for ancillary data. On other
MAYAH Codec it is possible to use RS-232 with a help of the RS232-USB
adapter (see chapter 'Introduction/Useful Accessories' of the corresponding
device manual).
The following ancillary data parameters can be set:
· Baudrate: Baud rates from 1,200 to 115,200
· Databits: 5, 6, 7, 8
· Parity: None, Even, Odd
Definition of parity:
A technique to test the integrity of digital data by checking an extra bit that
holds a 0 or 1, depending if the data is an even number of 1 bits or an odd
number of 1 bits.
· Stop Bits: 1, 2
· Handshake: None, Xon/Xoff, RTS/CTS, DSR/DTR
Handshaking means that signals are transmitted back and forth to control (i.e.
to start and stop) the transmission.
In most cases ancillary data transfer between two MAYAH devices
can be done automatically. This also includes transportation of the
data from/to GPIO interface. Additionally the parameter 'Format' for
Encoder and Decoder can be set for each Codec Profile via Web
Remote or by using a direct command. This may be necessary for
some scenarios, e.g. when transmitting ancillary data to non-MAYAH
devices or using some other algorithms than MPEG-based. Since the
Webremote 4 Manual
79
ancillary data implementation of the MAYAH Codec is the same as
for the CENTAURI II codecs, you can find more background
information in its manual. Visit www.mayah.com/help to download it
or to browse on-line.
3.5.6.16 Redundancy
This is a special feature for IP Codecs like Centauri IV and C10/C12 with two
separate Ethernet interfaces.
Data transmissions via an IP network could suffer from packet loss and or packet
corruption. To reduce the risk of packet loss and to increase the reliability of a
connection the codecs mentioned above are capable of doubling the IP stream to
send it via a secondary network interface to physically separated networks. With
this redundancy the total error rate can be reduced significantly.
A big advantage when using the Web Remote is the possibility to save up to 10
different redundant streaming routes.
When creating a new route or editing the existing one the following parameter
can be set:
a) Name
Enter the name for the route which will be then displayed in the DIRECT tab
when the Redundant Mode is chosen
b) Direction
Allows to set the direction for the redundant stream route
· send (Encoder only)
· recv (Decoder only)
· sendrcv (bi-directional connection)
c) Primary IP [LAN 1]
Here the primary IP address of the connection partner must be entered
Webremote 4 Manual
80
d) Redundant IP [LAN]
Here the redundant IP address of the connection partner must be entered
·
·
·
Please note that the primary stream is sent via the Ethernet
interface which is normally used for audio transmission (labeled
LAN1 on the device). Redundancy stream will be sent via the
Ethernet interface which is also used for control tasks (labeled
LAN on the device). See also the device manuals.
Attention should be paid to the correct network configuration,
including address, netmask, gateway (if necessary) for both
interfaces!
The IP port for the redundancy connection is equivalent to the
primary RTP port plus 1000. E.g. default RTP port for audio
streaming is 5004, hence the redundancy connections will be
done via the port 6004.

3.5.6.17 MPEG TS
In this menu various types of streaming sessions can be predefined and saved
for later use. Major application for such sessions is audio streaming based on
MPEG Transport Stream (TS) standard. However, some other session types are
supported (see below). The MPEG TS standard which was adopted as ISO/IEC
13818–1 defines ways of multiplexing more than one stream (audio, video and
data) into one program. A program consists of one or more Program Elementary
Streams (PES), which may or may not be MPEG encoded.
When creating a new Session or editing the existing one the following parameter
can be set:
Webremote 4 Manual
81
a) Session Name
Enter the name for the session which will be then displayed in the DIRECT tab
when the MPEG TS is chosen as connection mode
b) TS Mode
Allows to set the Session Mode to:
· MPEG TS (default)
· DMB
· DVB
c) Interface
Allows to set the interface to:
· Net (Ethernet)

g. separately for connection 1 and 2 at Dual Mode IP applications.
With Prioritization it is possible to provide a Quality of Service (QoS) mechanism
by modifying bytes in the IP header.
The Prioritization page is divided into three sections:
·
·
·
Type Of Service/DiffServ
Subcodec
VLAN
Default state of prioritization on a C11xx
a) Type Of Service (ToS) / Diffirentiated Services (DiffServ)
The Type of Service (TOS) uses a byte that describes a preference for how a
datagram should be handled by network devices. The three most significant
bits of that byte are pooled to the setting "Precedence".
After choosing a precedence setting the status of the check boxes for
"Precedence 0" to "Precedence 2" will change appropriately. The lowest bits can
be set individually by clicking on the corresponding check boxes.
The same byte that is used for TOS can be interpreted by the more modern
Differentiated Service (DiffServ). If display mode is changed from TOS to DiffServ
the setting for the Bit Field is preserved but is interpreted differently. The six most
significant bits are pooled to form a DS field which bits are called DSCP
(Differentiated Services Code Point). The intended policy and priority for a packet
traversing a network node is called the "Per-Hop Behaviour".
Some forwarding values are predefined like "default" and "expedited". If
"assured" is chosen a list of additional presets will be displayed.
The Per-Hop Behaviour "User Defined" allows the user to set all bis individually.
Webremote 4 Manual
84
The last two bits not being part of the DS field are used for Explicit Congestion
Notification (ECN). To alter the ECN status the Per-Hop Behaviour must be set to
“User Defined”.
b) Subcodec
Prioritization can be set for each subcodec individually
c) VLAN
Two parameters can be configured for a tagged Virtual Local Area Network
(VLAN), the Traffic Type and an Identifier. The preset names for the traffic type
can vary from manufacturer to manufacturer. MAYAH Web Remote uses the
name "Best Effort" for the lowest priority (value 0) up to the highest priority
"Network Control" (value 7).
Changing VLAN settings will interrupt all IP activity on the device.
You may have to reload the Web Remote and/or resume other IP
connections from/to the device. If VLAN configured improperly, you
may loose an access to audio-related traffic of the device.
Please note that only audio-related traffic can be prioritized or tagged
with MAYAH Codec, e.g. RTP audio, SIP messages etc. Control
traffic (Web Remote, SNMP, Telnet etc) cannot be prioritized or
tagged
3.5.6.20 Miscellaneous
a) Device ID
Here the name of the MAYAH Codec can be entered (max. 128 characters). This
ID is displayed in the title of the Web Remote HTML page, as well as transmitted
to the remote codec if connection is done between MAYAH devices.
Webremote 4 Manual
85
b) Date/Time
Here the current Date and Time settings of the MAYAH Codec can be modified.
Correct date and time are particularly important for the log files in any technical
support case, as well as for correct properties of the recorded files (if supported).
It is strongly recommended to synchronize your MAYAH Codec with an NTP
server to be able to use the exact date & time. See also the chapter 'SETUP/NTP
'.
c) Timeouts
Here the following timeouts can be set:
· Disconnect:
This timeout defines the period (in seconds) after which a connection is
dropped if no valid framing is achieved. Ideally, it should be set higher than
the Stat. framing timeout value.
Its default value is 45 seconds.
· Remote Timeout [Telnet]
This timeout defines the period (in seconds) after which an idle Telnet remote
control session is closed automatically. The default value is 100 seconds.
Note:
This timeout can be helpful if a remote session was interrupted by the network
(e.g. faulty switch) and new remote control attempts are blocked by MAYAH
Codec since it is 'convinced' it is still remote controlled (but it isn't).
· G.722 Timeout (usually only important at ISDN transmissions)
This timeout defines the period (in seconds) after which MAYAH Codec
switches automatically to G.722 SRT coding at non-IP transmissions.
Generally, there are two methods to synchronize G.722 data streams.
- G.722 with H.221 (in-band signalling): H.221 uses a small amount of the
data capacity (i.e.1.6 kbps of 64 kbps) to transmit the synchronization
information in-band. Although G.722/H.221 is a recommended EBU standard,
it’s not very widespread.
- G.722 SRT (Statistical Recovery Timing): Synchronization requires finding
the start bit of every G.722 octet, and is reached by evaluating the data
pattern of the signals statistically. We DON’T recommend that you use a pure
sine wave signal whilst trying to achieve synchronization, using G.722 SRT
coding! This G.722 timer starts once the first ISDN line is connected. It is
recommended that the G.722 SRT timeout be set to ~30 Seconds. This value
is high enough not to interrupt any auto-detection process, but should still be
acceptable for framing up.
d) Connections
·
Accept Mode
Here can be set if incoming calls (via Ethernet, ISDN, UMTS/3G, POTS or
WLAN) are accepted automatically (default) or manually
At current version the confirmation of the manual call accept can
only be done via front panel controls of the MAYAH Codec. Do
not activate this feature if you're operating the MAYAH Codec
entirely via Web Remote.
Webremote 4 Manual
86
·
Auto Restore
Here can be set if actively established connections will be resumed
automatically after power loss (e.g. switching MAYAH Codec off and on during
the active connection established from this particular unit).
- Auto (default, at the current firmware version: auto = on)
- On (MAYAH Codec will resume connection)
- Off (MAYAH Codec will not resume connection)
· For most broadcasting production applications the positions
"Auto" or "On" can be selected for automatic reconnection after
possible power failure in a live transmission situation.
· At the same time for most recording studio / voice over
applications this function can be disabled to avoid automatic
reconnection upon power restore and thus avoiding undesired
distant call costs.
3.5.7
