Additional trunks can be better used to increase the connectivity and capacity of the
network, instead of as parallel trunks. For example, the configuration on the right side
of Figure 7-1 is a better use of trunks than the one on the left.

Required and Optional Configuration
To support a trunk, make sure the following are correctly configured in the database:
●
Network Defaults , described in Chapter 4. This file must be configured for a
new network. After that, no further changes are generally necessary.
●
Node parameters , described in Chapter 5. A record must exist for every node on
the network.
●
Line Processor , described in Chapter 6. A record must exist for every LP in
every node on the network.
●
Port , described on page 7-3. A record must exist for every port on every LP in
every node. Each trunk port’s record will identify the trunk port and define its
operating parameters.
●
Modem Initialization record, described on page 7-11, if the (RS-232 physical
interface only) port will be connected to a V.25bis modem.
●
Subscriber IDs , described on page 7-17. A record must be created for each
called and calling address specified in logical trunk records.
●
PVC Connection record, described on page 7-20. A record is necessary if you
want to create a “permanent” connection between an FRX8000 logical trunk
port and its underlying physical X.25 port.
●
Telephone number , described page 7-23, if the port will be connected to a
V.25bis modem.
