How to use Abacus5000 and PAD-5000 to test
voice quality of SIP phone
1
1. Instruction
PAD-5000 is used with Abacus5000 to perform voice quality measurements on IP
phones using analog signals.
2. Equipment
Abacus5000: ECG3 and ICG3
PAD-5000
3. Interconnection of PAD-5000 and Abacus5000
1) Connect a two-wire (minimum) RJ-11 cable from the PAD-5000 ECG3 socket to any
of the 14 RJ-11 sockets on the ECI3RJ rear card of the ECG3 subsystem.
2
2) Connect one end of an Ethernet cable to the local area network socket of the IP phone.
This is an RJ-45 connector, and will typically be marked LAN or Ethernet.
3) Connect the other end of the Ethernet cable to Ethernet connector 0 (copper wire) on
the rear-panel card (IFI3 or IDI3) of the Abacus 5000 ICG3B or ICG3C subsystem.
4) Disconnect the modular plug of the four-wire RJ-22 cable attached to the telephone
handset. Replace the handset on the phone to keep the switchhook depressed.
5) Attach the other end of this four-wire RJ-22 cable to the PHONE socket on the rear
panel of the PAD-5000.
Note: It might be necessary to replace this RJ-22 cable with the supplied crossover cable
(Spirent P/N 65-03512) if it is later discovered that the IP telephone handset connector is
wired differently from that of the PAD-5000.
