TZBIT[47:40]
Transmit Z-bits is applicable only in E1_MODE [CMD_1; addr 0xE5]; otherwise, Z-bit
registers are ignored. TZBIT[47:0] holds 48 Z-bits for transmission in the first bit of each of
the 48 payload blocks. (See Figure 3-16 for Z-bit positions within the frame.) The first eight
Z-bits are individually output for each channel from TZBIT_1. The last 40 Z-bits are output to
all channels from a single set of TZBIT_2–TZBIT_6.
NOTE: The system may also supply the last 40 Z-bits individually for each HDSL transmit
channel from the TAUXn inputs by setting TAUX_EN and EXT_ZBIT [TCMD_2;
addr 0x07].
