HW
Mode
Bit 0: Transmit-Side Bit 7 Zero-Suppression Enable (TB7ZS)
Bits 1 and 5: Unused, must be set = 0 for proper operation.
Bit 2: Transmit-Side D4 Yellow Alarm Select (TD4YM)
Bit 3: F-Bit Corruption Type 1 (FBCT1). A low-to-high transition of this bit causes the next three consecutive Ft (D4
framing mode) or FPS (ESF framing mode) bits to be corrupted causing the remote end to experience a loss of frame (loss of
synchronization).
Bit 4: F-Bit Corruption Type 2 (FBCT2). Setting this bit high enables the corruption of one Ft (D4 framing mode) or FPS
(ESF framing mode) bit in every 128 Ft or FPS bits as long as the bit remains set.
Bit 6: Transmit Fs-Bit Insertion Enable (TFSE). Only set this bit to a 1 in D4 framing applications. Must be set to 1 to
source the Fs pattern from the TFDL register. In all other modes this bit must be set = 0.
Bit 7: Transmit B8ZS Enable (TB8ZS)
0 = no stuffing occurs
1 = bit 7 forced to a 1 in channels with all 0s
0 = 0s in bit 2 of all channels
1 = a 1 in the S-bit position of frame 12
0 = Fs-bit insertion disabled
1 = Fs-bit insertion enabled
0 = B8ZS disabled
1 = B8ZS enabled
