Preliminary Information
MT9076
Bit
Name
Functional Description
7 - 3 RxTS4 - 0 Receive Time Slot. A five bit counter that indicates the number of time slots between
the receive elastic buffer internal write frame boundary and the ST-BUS read frame
boundary. The count is updated every 250 uS.
2 - 0 RxBC2 - 0 Receive Bit Count. A three bit counter that indicates the number of STBUS bit times
there are between the receive elastic buffer internal write frame boundary and the ST-
BUS read frame boundary. The count is updated every 250 uS.

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.

LLOSS 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.
