Transmit Idle Code. This is the idle code that is sent on the PCM24 channels if the per timeslot
control bit MPDT is set(Y90-YA7).
not used.
Receive Bit Oriented Message Match. The contents of this register are compared to the
received bit oriented message register(RXBOM) and an option maskable interrupt is generated if
the contents match the received bit oriented message. Note that in accordance to T1.403 Table
11 the codeword 7E should not be used due to similarity of DataLink idle code. The code 7E will
not be detected by the MT9072.
not used.
Receive Idle Code. This is the idle code that is sent on the DSTo channels if the per timeslot
control bit MPDR is set(Y90-YA7).

not used.
CST Map Channel. This is the CSTi/o channel which will be used as a source/destination to
be mapped to the PCM24 channel. The possible values are 0 to 23 for channels 0 to 23 of the
CSTi/o streams.
PCM Map Channel. This is the PCM24 timeslot which will be used as a source/destination to
be mapped to the CSTi/o channel. The possible values are 0 to 23 for timeslots 0 to 23 of the
PCM24 stream.
