Configuring Call Routing
Understanding the call-routing database
Some slot cards act in a dual capacity, performing both network and host functions. Some
dual-purpose cards provide their own HDLC resources. For example, T1 and E1 FrameLine
cards have HDLC channels integrated into the card and support Frame Relay protocols.
Other cards establish the physical connection and terminate calls. Calls on these cards do not
require additional HDLC processing.
The following table shows a representative listing of cards in each category:
Understanding the call-routing database
The Callroute command displays entries in the call-routing database. You can display entries
for network, host, or dual-purpose devices, or list entries by device. For example, the Callroute
command with the -ad flag displays database entries for dual-purpose devices:
admin> callroute -ad

Table 19-1. Fields in a call-routing database entry
Field Contains
Device The address of a device installed in the system to which calls
matching the entry will be routed. The address has the following
format:
shelf:slot:line/channel
For example, shelf 1, slot 2, line 1, channel 24 is addressed as
1:02:01/24.
# The call-routing entry number. For default entries (entries
created by the system for a device) the value is always zero. For
entries created by Call-Route profiles, the number must be
unique for each entry that has the same Device address. For
details, see “Call-Route profile settings” on page 19-5.
