Note: These registers are only used in E1 mode. The RDMWE1-T1 – RDMWE3-T1 registers are used in T1 mode.
Bits 7 to 0 (x4): E1 Rx Digital Milliwatt Enable for Channels 1 to 32 (CH1 to CH32). Register bit RCR3.uALAW
spe
cifies whether u-law or A-law coding is used for the digital milliwatt code. See section 10.11.13.
0 = Do n
ot affect the Rx data associated with this channel
1 = Replace the Rx data associated with this channel with digital milliwatt code
Register Name:

Bit 7: Receive CRC-16 Display (RCRCD). See section 10.12.1.
0 = Do not write received CRC-16
code to FIFO. (default)
1 = Write received CRC-16 code to FIFO after last octet of packet.
