DESCRIPTION
The PM5366 High Density 84/63 Channel VT/TU Mapper and M13 Multiplexer
(TEMAP-84) is a feature-rich device for use in any applications requiring high
density link termination over T1 and E1 (G.747) channelized DS3 or T1 and E1
channelized SONET/SDH facilities.
The TEMAP-84 supports asynchronous multiplexing and demultiplexing of 84
1.544 Mbit/s or 63 2.048 Mbit/s tributaries into three DS3 signals as specified by
ANSI T1.107, Bell Communications Research TR-TSY-000009 and ITU-T Rec.
G.747. It supports bit asynchronous or byte synchronous mapping and
demapping of 84 T1s or 63 E1s into SONET/SDH as specified by ANSI T1.105,
Bell Communications Research GR-253-CORE and ITU-T Recommendation
G.707. The TEMAP-84 also supports mapping of 63 T1s into SDH via TU-12s.
Up to 84 Transparent VT1.5s and TU-11s or 63 Transparent VT2s and TU-12s
can be transferred between the SONET/SDH interface and the SBI bus
interface.
This device can also be configured as a DS3 or E3 framer, providing external
access to the full DS3 or E3 payload, or a VT/TU mapper, providing access to
unframed 1.544 Mbit/s and 2.048 Mbit/s links.
The TEMAP-84 can be used as a SONET/SDH VT/TU mapper or M13
multiplexer with performance monitoring in either the ingress or egress direction
for up to 84 T1s or 63 E1s.
Each of the T1 and E1 jitter attenuators and performance monitors is
independently software configurable, allowing timing master and feature
selection without changes to external wiring. 1.544 Mbit/s and 63 2.048 Mbit/s
tributaries may be mixed at a VC-3/TUG-3/DS3 granularity.
In the ingress direction, each of the 84 T1 links is either demultiplexed from a
channelized DS3 or extracted from SONET VT1.5, TU-11 or TU-12 mapped bus.
Each T1 performance monitor can be configured to frame to the common DS1
signal formats (SF, SLC96, ESF).
T1 performance monitoring with accumulation of CRC-6 errors, framing bit
errors, out-of-frame events, and changes of frame alignment is provided. . The
TEMAP-84 also detects the presence of ESF bit oriented codes, and detects and
terminates HDLC messages on the ESF data link. The HDLC messages are
terminated in a 128 byte FIFO.
