Communications Processor (CP)
terminal data stream over the B channel. That SCC would be configured for HDLC mode if
V.120 rate adaption is required, or for V.110 mode if V.110 rate adaption is required. The
second B channel could be routed to the CODEC as a digital voice channel, if desired. The
SCP is used to send initialization commands and periodically check status from the S/T
transceiver. The SCC connected to the terminal would be configured for UART, BISYNC, or
DDCMP mode depending on the terminal protocol used.
The IMP has two output data strobe lines (SDS1 and SDS2) for selecting either or both the
B1 and B2 channels. These signals are used for interfacing devices that do not support the
IDL bus. These signals, configured by the SIMASK register, are active only for bits that are
not masked. The IDL signals are as follows:
