2REB2

Receive E2 Bit Status. Indicates the status of the bit (E2) received on the PCM30 link in bit

position 1 of timeslot 0 in non-frame alignment signal (NFAS) frame 15. If zero, the remote end

calculated a CRC-4 error in its received sub-multiframe two. If one, no error was calculated.

RCRCR Remote CRC-4 and RAI. If one, the RAI (A) status bit (register address Y12 and Y13) is one,

and the REB1 (E1) and REB2 (E2) status bits (register address Y10) are zero. If zero, the

above requirement is not met.

CRCIW CRC-4 Interworking. If one, indicates the CRC-4 interworking status is CRC-4 to CRC-4 (local

to remote). The transmit PCM30 link is framed to CRC-4 with E1 and E2 bits sent, and the

receive PCM30 link is treated as CRC-4 with E1 and E2 bits received. If zero, indicates the

CRC-4 interworking status is CRC-4 to non-CRC (local to remote). In this case, the transmit

PCM30 link is framed to CRC-4 but the E1 and E2 bits are not sent, and the receive PCM30 link

is not treated as a CRC-4 multiframe but only as a basic frame and signaling multiframe frame

only.
