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.
and the REB1 (E1) and REB2 (E2) status bits (register address Y10) are zero. If zero, the
above requirement is not met.
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.
