Data Sheet

MT8931C

The B1 and B2 channels each have a bandwidth of

64 kbit/s and are used to carry PCM voice or data

across the network.

The D-channel is primarily intended to carry

signalling information for circuit switching through

the ISDN network. The SNIC provides the capability

of having a 16 kbit/s or full 64 kbit/s D-channel by

allocating the B1-channel timeslot to the D-channel.

Access to the depacketized D-channel is only

granted through the parallel microprocessor port.

The C-channel provides a means for the system to

control and monitor the functionality of the SNIC.

This control/status channel is accessed by the

system through the ST-BUS or microprocessor port.

The C-channel provides access to two registers

which provide complete control over the state

activation

machine,

the

D-channel

priority

mechanism as well as the various maintenance

functions. A detailed description of these registers is

discussed in the microprocessor port interface.

Line Code

The line code used on the S-interface is a Pseudo

ternary code with 100% pulse width as seen in

Figure 5 below. Binary zeros are represented as

marks on the line and successive marks will

alternate in polarity.

A mark which does not adhere to the alternating

polarity is known as a bipolar violation.
