Table 108 - Receive Frame Alignment Signal
Table 109 - Receive Signal Status Word
Receive International Use Zero. This is the bit which is received on the
PCM30 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.
Receive Frame Alignment Signal Bits 2 to 8. These bit are received on the
PCM30 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.
Peak Detector Voltage Levels. These five bits indicate the level of the
received signal AMI pulses.

LIU Loss of Signal indication. This bit will be high if the received signal is
below the threshold selected by ELOS (page 2, address 10H) for a period of
at least 1 msec. This bit will be low for normal operation.
