COMBINED E1/T1 TRANSCEIVER
This bit must be set to logic 0 when not in T1 ESF mode.
CRCBYP:
In T1 mode, when the CRCBYP bit is a logic 1, the framing bit corresponding
to the CRC-6 bit position in the input data stream, BTPCM, passes
transparently to the transmit output data stream. When CRCBYP is set to
logic 0, the XBAS is allowed to generate the output CRC-6 bits.
This bit must be set to logic 0 when not in T1 ESF mode.
FDLBYP:
In T1 mode, when the FDLBYP bit is a logic 1, the framing bit corresponding
to the facility data link bit position in the input data stream, BTPCM, passes
transparently to the transmit output data stream. When FDLBYP is set to
logic 0, the XBAS is allowed to generate the output facility data link.
This bit must be set to logic 0 when not in T1 ESF mode.
