Bits 8 to 12: Transmit BERT Port Select Bits 0 to 4 (TBPS0 to TBPS4). These bits determine if the transmit
BERT will be used to replace the normal transmit data on any of the 28 T1 or 16/21 E1 transmit ports or at the
T3/E3 transmit formatter. If these bits are set to 11101, data from the transmit BERT is only placed in the payload
bit positions of the T3/E3 data stream. If these bits are set to 11110, then data from the transmit BERT is placed
into all bit positions of the T3/E3 data stream (payload and the overhead bits).
