Receive Z-bits—Applicable only in E1_MODE [CMD_1; addr 0xE5]. RZBIT holds 48 Z–bits
received during the previous HDSL frame. Refer to Figures 3-21 and 3-26 for Z–bit positions
within the frame. The LSB RZBIT[0] is received first. The first 8 received Z-bits from each
HDSL channel are individually monitored in the RZBIT_1 registers. The last 40 received
Z-bits are monitored in the RZBIT_2–RZBIT_6 registers from only the single receive channel
selected by ZBIT_SEL [CMD_5; addr 0xE9]. Systems which need individual channel
monitoring of the last 40 Z-bits can use external circuitry to capture the Z-bits from the receive
HDSL auxiliary channel (RAUXn) outputs.
