t1 specifies a T1 BITS signal.
esf-b8zs is ESF framing with B8ZS line coding.
sf-d4 is SF-D4 framing with AMI line coding.
slc96 is SLC96 framing with AMI line coding.
t1dm is T1DM framing with AMI line coding

support.
pcm31-hdb3 is PCM-31 framing with HDB3 line coding and CRC
Multiframe support.

Multiframe support.
a specifies the Input A port on the SRM I/O module.
b specifies the Input B port on the SRM I/O module.
2. To verify the primary network clock source information that you have configured,
use the show network-clocks command in Global Configuration mode, as shown
in the following example:
BSR(config)#show network-clocks
Figure 14-1 show network-clocks Command Output
Setting the Secondary BITS Network Clocking Source
Follow these steps to set the secondary network clocking source:
1. Use the network-clock-select 2 bits command in Global Configuration mode to
identify the secondary network clock and define the network clocking port on the
SRM I/O module from which the T1 or E1 BITS signal is derived, as shown in
the following example:
