The following sections describe limitations of the new software features supported by the Cisco 1700 
series routers for Release 12.2(11)YV2.

Once a channel bank connection is configured, the presence or absence of traffic cannot be indicated 
to the user.

The users hear silence (not a busy signal) if the DSO time slot of a configured channel bank 
connection is busied out during the call. The channel bank connection will go down when the DSO 
time slot is busy.

The show voice port command will not return the correct call state of a configured channel bank 
connection. The command always reports the port as being idle.

Channel bank requires digital signal processing (DSP) resources for signaling. If the DSP fails, the 
connection will be down until the DSP recovers automatically.

The port LED will not indicate the hook state of the analog port.

The caller ID feature will not be available on the ports of a channel bank.

During periods of high CPU use, signaling transfer between the ports of channel bank could be 
delayed.
