CCR5.6
Backplane Clock Select 0. See Table 4-3 for details.
MM1
CCR5.5
Monitor Mode 1. See Table 4-4.
MM0
CCR5.4
Monitor Mode 0. See Table 4-4.
RSCLKE
CCR5.3
Receive Synchronization Clock Enable. This control bit determines
whether the line receiver should handle normal T1/E1 signals or a
synchronized signal.
E1 mode:
0 = receive normal E1 signal (Section 6 of G.703)
1 = receive 2.048 MHz synchronization signal (Section 10 of G.703)
T1 mode:
0 = receive normal T1 signal
1 = receive 1.544 MHz synchronization signal
TSCLKE
CCR5.2
Transmit Synchronization Clock Enable. This control bit determines
whether the transmitter should transmit normal T1/E1 signals or a
synchronized signal.
E1 mode:
0 = transmit normal E1 signal (Section 6 of G.703)
1 = transmit 2.048 MHz synchronization signal (Section 10 of G.703)
T1 mode:
0 = transmit normal T1 signal
1 = transmit 1.544 MHz synchronization signal
RT1
CCR5.1
Receive Termination 1. See Table 4-5 for details.
