Nortel Networks 311 Interconnection

Architecture 869
•integrated trunk access (both D-channel and in-band A/B signaling can
be mixed on the same PRI)
•faceplate monitor jacks for T-1 interface
•configurable D-channel data rate with 64 Kbps, 56 Kbpsor 64 Kbps
inverted.
•self-test
Architecture
Signaling interface
The signaling interface performs an 8 Kbps signaling for all 24 channels
and interfaces directly to the DS-30X link. Messages in both directions of
transmission are three bytes long.

Interconnection
The interconnection to the carrier is by NTBK04 1.5 Mb carrier cable.
The NTBK04 is twenty feet long. The NT8D97AX, a fifty-foot extension,
is also available.

Microprocessor
The NTAK09is equipped with bit-slice microprocessors that handle the
following major tasks:
•Taskhandler: also referred to as an executive,the task handler provides
orderly per-channel task execution to maintain real-time task ordering
constraints.
