Tellabs 1000 Multiservice Access Platform (MSAP) HDSL2 Transceiver (T1HD2-XCVR) ®

TELLABS DATA SHEET
Tellabs® 1000 Multiservice Access Platform (MSAP)
HDSL2 Transceiver (T1HD2-XCVR)
Overview
The T1HD2 transceiver plug-in card provides one T-1 rate interface,
over one copper pair, using standard HDSL2 (ANSI T1.418). This
line card supports CSA transmission distances over 26 AWG and
24 AWG (i.e., 9 kft and 12 kft respectively) and supports up to
one (1) HDSL2 repeater in a span. The T1HD2 provides the benefit
of using existing copper facilities to support applications such
as transport between Tellabs® 1000 terminals and for providing
legacy T-1 services. The T1HD2 also provides better spectral
compatibility with ADSL, supporting transmission of HDSL2 and
ADSL in the same binder group. Further, up to 20 T1HD2 cards
can be installed in a single shelf with repeater support.

The T1HD2-XCVR card can function in an unframed format to
allow for intact (asynchronous) T-1 delivery to subscribers. It can
also function in a framed format to deliver groomed T-1 service.
The T1HD2-XCVR may be used for T-1 transport between Tellabs
1000 terminals and supports Tellabs 1000 multiservice access
platform span protection. The T1HD2-XCVR performs ANSI
signaling conversion and data link termination. The transceiver
supports TC PAM encoding, alarm thresholds, BER calculation,
performance monitoring statistics and alarm history.

The T1HD2-XCVR transmits over unconditioned, non-repeatered
facilities. For longer transmission distances, the T1HD2 is capable
of line powering one ADTRAN HDSL2 range extender (HRE)
and one HDSL2 Termination Unit (HTU), supporting up to 24 kft
on 24 AWG. For all applications, copper facilities may be utilized
without removing bridged taps or providing binder group
separation. Bridged tap parameters support either one continuous
tap (not greater than 2,000 feet) or total tap distances not to
exceed 2,500 feet.
