Several functional blocks exist in the transceiver. The
transmit framer/formatter generates appropriate fram-
ing bits, inserts robbed bit signaling, supervises zero
suppression, generates alarms, and provides output
clocks useful for data conditioning and decoding.
The receive synchronizer establishes frame and multi-
frame boundaries by identifying frame signaling bits, ex-
tracts signaling data, reports alarms and transmission
errors, and provides output clocks useful for data condi-
tioning and decoding.
The control block is shared between transmit and re-
ceive sides. This block determines the frame, zero sup-
pression, alarm and signaling formats. User access to
the control block is by one of two modes.
In the processor mode, pins 14 through 18 are a micro-
processor/microcontroller-compatible serial port which
can be used for device configuration, control and status
monitoring.
In the hardware mode, no offboard processor is re-
quired. Pins 14 through 18 are reconfigured into “hard-
wired” select pins. Features such as selection “clear”
DS0 channels, insertion of idle code and alteration of
sync algorithm are unavailable in the hardware mode.
