Bit 2: Receive BERT Port Direction Control (RBPDIR). See section 10.14.3.
0 =
Normal (line) operation. Rx BERT port sources data from the receive path (i.e. from the LIU direction).
1 = Reverse (system) operation. Rx BERT port sources data from the transmit path (i.e. from the TDMoP
direction).
Bit 1: Receive BERT Port Framed/Unframed Select (RBPFUS). T1 Mode Only. See section 10.14.3.
0 = Do
n’t clock data from the F-bit position (framed)
1 = Clock data from the F-bit position (unframed)
Bit 0: Receive BERT Port Enable (RBPEN). See section 10.14.3.
0 = Re
ceive BERT port is not active
1 = Receive BERT port is active.
