DESCRIPTION
Back Plane Clock Select 1.
See Table 6-3 for details.
Back Plane Clock Select 0.
See Table 6-3 for details.
Monitor Mode 1.
See Table 6-4.
Monitor Mode 0.
See Table 6-4.
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
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
Receive Termination 1.
See Table 6-5 for details.
Receive Termination 0
