DESCRIPTION
The TranSwitch Multi-rate Receive/Transmit (MRT)
device is a CMOS VLSI device that provides the func-
tions needed for terminating two CCITT line rates, 8448
and 34368 kbit/s, and a 6312 kbit/s rate which is speci-
fied in the Japanese NTT Technical Reference for High
Speed Digital Leased Circuits. For 8448 and 34368 kbit/s
operation, the MRT provides an optional HDB3 codec.
The MRT is equipped with a receive equalizer circuit and
AGC. The MRT also provides a rail or NRZ interface,
HDB3 error rate monitor, alarm detection, and AIS gener-
ators. Testing capability is provided by transmit and
receive loopbacks.
