Configuring T1-CAS Analog Emulation (H.323)
The number of digits that you substitute for pattern plus the number of periods in
the wildcard (...) must match the total number of digits configured for use by the
Catalyst 4224 in Cisco CallManager Administration. Also, remember that the
numbers that you substitute for pattern are removed by the Catalyst 4224. When
the call is forwarded to the destination number, only the digits in the position of
the wildcard pattern (...) are received by the destination endpoint. If you want to
replace the digits that are stripped off (or add a different set of digits), use the
prefix command.
Step 6 Complete and save the configuration by entering the following commands:
c4224# line con 0
c4224# transport input none
c4224# line aux 0
c4224# line vty 0 4
c4224# login
c4224# no scheduler allocate
c4224# end
c4224# copy running-config startup-config

Configuring T1-CAS Analog Emulation (H.323)
You can connect the T1-CAS (channel-associated signaling) port on a
Catalyst 4224 to one of the following:
• The PSTN using Foreign Exchange Office (FXO) emulation
• A T1 channel bank using Foreign Exchange Station (FXS) emulation
• A PBX with a trunk (tie) line using Ear and Mouth (E&M) emulation
To configure T1-CAS analog emulation with H.323 T1, perform the following
steps. After completing these steps, configure the route pattern and dial plan and
save your configuration, as described in “H.323 Gateway Configuration” section
on page 5-16.
