HIGH DENSITY VT/TU MAPPER
AND M13 MULTIPLEXER
6
DESCRIPTION
The PM5365 VT/TU Mapper and M13 Multiplexer (TEMAP) is a feature-rich
device for use in any applications requiring high density link termination over T1
channelized DS3 or T1 and E1 channelized SONET/SDH facilities.
The TEMAP supports asynchronous multiplexing and demultiplexing of 28 DS1s
into a DS3 signal as specified by ANSI T1.107 and Bell Communications
Research TR-TSY-000009. It supports bit asynchronous mapping and
demapping of 28 T1s or 21 E1s into SONET/SDH as specified by ANSI T1.105,
Bell Communications Research GR-253-CORE and ITU-T Recommendation
G.707. The TEMAP also supports mapping of 21 T1s into SDH via TU-12s. Up to
28 Transparent VT1.5s and TU-11s or 21 Transparent VT2s and TU-12s can be
transferred between the SONET/SDH interface and the SBI bus interface.
Performance monitoring in either the ingress or egress direction for up to 28 T1s
or 21 E1s in both SONET/SDH VT/TU mapper and M13 multiplexer modes.
Each T1 performance monitor detects and indicates the presence of Yellow and
AIS patterns and also integrates Yellow, Red, and AIS alarms. T1 performance
monitoring with accumulation of CRC-6 errors, framing bit errors, out-of-frame
events, and changes of frame alignment is provided.
Each E1 framer detects and indicates the presence of remote alarm and AIS
patterns and also integrates Red and AIS alarms.
The E1 framers support detection of various alarm conditions such as loss of
frame, loss of signaling multiframe and loss of CRC multiframe. The E1 framers
also support reception of remote alarm signal, remote multiframe alarm signal,
alarm indication signal, and time slot 16 alarm indication signal.
E1 performance monitoring with accumulation of CRC-4 errors, far end block
errors and framing bit errors is provided.
This device can also be configured as a DS3 framer, providing external access to
the full DS3 payload, or a VT/TU mapper, providing access to unframed
1.544Mb/s and 2.048Mb/s links.
PRBS generation or detection is supported on a per T1 or E1 link basis.
The TEMAP can generate a low jitter transmit clock from a variety of clock
references, and also provides jitter attenuation in the receive path. Two low jitter
recovered T1 clocks can be routed outside the TEMAP for network timing
applications.
