The rest of the administration options are essentially the same as for the 100D module.
For more information on configuring the 100D module, see System Programming manual

changed during active voice calls. In this case, the change in CSU status occurs after all
active voice calls have been terminated.
Deactivating the CSU has the following impact on 100R module operation:
•
The 100R board does not respond to network initiated loopback requests.
•
The 100R board does not send T1 performance statistics to the network.
•
The line compensation value used by the 100R board corresponds to the DTE
settings appropriate for a 100D module instead of a CSU. The DTE and CSU values
are summarized in Table C-1
