Chapter 3 Operations
Verifying Modem Performance
Tips For channel associated signaling (CAS), robbed bit signaling (RBS), and R2, use the debug
cas command. If this command is not included in your software, use the modem-mgmt
csm debug-rbs command; however, the service internal command is required.
5800-NAS(config)#service internal
5800-NAS(config)#end
5800-NAS#modem-mgmt csm debug-rbs
At the time of this publication, the Cisco AS5800 does not support the debug cas command or
modem-mgmt csm debug-rbs command. As a workaround, complete the following steps:
a. Determine the slot positions of each card. Enter the show dial-shelf command.
b. Access the trunk card’s console port. Enter the dsip console slave X command where X is the slot
of the card that you want to perform debugging on.
c. Enter the command debug trunk cas port port-number timeslots range.
Step 4 Ensure that your EXEC session receives logging and debug output from the NAS:
5800-NAS#logging console
Step 5 From the client Telnet session, Telnet into one of the idle modems (not in use). To do this, Telnet to an
IP address on the NAS (Ethernet or Loopback) followed by 2000 plus a TTY line number. This example
Telnets to TTY line 1 (2001).
5800-NAS#telnet 172.22.66.23 2001
Trying 172.22.66.23, 2001 ... Open
Note This step is also known as a reverse Telnet.
For a Cisco AS5800, create an arbitrary IP host followed by a reverse Telnet. Use the show modem
shelf/slot/port command to determine which modem is associated with which TTY line. The following
example Telnets to TTY 500, which maps to modem 1/2/68.
5800-NAS#show modem 1/2/68

--- --- ------ ----- - -------- --- --- --- ---
