PEB 3456 E
General Overview
Facility data link, Signaling controller
The facility data link exchanges the ‘F-bits’ of the T1 links or the S
-bits of time slot zero
a
of the E1 links with the framer block and it provides the function of HDLC formatting or
BOM mode in receive and transmit direction.
The signalling controller also provides access to the DS3 signalling bits (Far End Alarm
and Control Channel, Path Maintenance Data Link Channel).
Message FIFO
For intermediate buffering of data link messages two FIFOs are integrated, one for
transmit and one for receive direction. Each FIFO provides two pages of 32 bytes buffer
per line and direction.
JTAG
Boundary Scan logic according to IEEE 1149.1.
