Functional Description
7
SYNC
Receive Basic Frame Alignment.
SYNC indicates the basic frame
alignment status (1 - loss; 0 -
acquired).
6
MFSYNC
Receive Multiframe Alignment.
MFSYNC indicates the multiframe
alignment status (1 - loss; 0 -
acquired).
5
CRCSYN
Receive CRC-4 Synchronization.
CRCSYN indicates the CRC-4
multiframe alignment status (1 -
loss; 0 - acquired).
4
REB1
Receive E-Bit One Status.
REB1
indicates the status of the received
E1 bit of the last multiframe.
3
REB2
Receive E-Bit Two Status.
REB2
indicates the status of the received
E2 bit of the last multiframe.
2
CRCRF
CRC-4 Reframe.
A one indicates
that the receive CRC-4 multiframe
synchronization could not be found
within the time out period of 8 msec.
after
detecting
synchronization. This will force a
reframe when the maintenance
option is selected and automatic
CRC-4 interworking is de-selected.
basic
frame
1
RED
RED Alarm.
RED goes high when
basic frame alignment has been lost
for at least 100 msec. This bit will be
low when basic frame alignment is
acquired (I.431).
0
CRCIWK
CRC-4
Interworking.
CRCIWK
indicates the CRC-4 interworking
status (1 - CRC-to-CRC; 0 - CRC-
to-non-CRC).

RIU0
Receive International Use Zero.
This is the bit which is received on
the PCM 30 2048 kbit/sec. link in bit
position one of the frame alignment
signal. It is used for the CRC-4
remainder or for international use.
6 - 0
RFA2-8
Receive Frame Alignment Signal
Bits 2 to 8.
These bit are received
on the PCM 30 2048 kbit/sec. link in
bit positions two to eight of frame
alignment signal. These bits form
the frame alignment signal and
should be 0011011.
