Configuring with the Command-Line Interface
Configuring ISDN BRI WAN Interface Cards
Configuring ISDN BRI Lines
Before using a router with an ISDN BRI interface, you must order a correctly configured ISDN BRI line
from your local telecommunications service provider.
Step 8
Router(config-if)# exit
Exit back to global configuration mode.
Repeat Step 5 through Step 7 if your router has
more than one BRI interface that you need to
configure.
Step 9
Router(config-if)# memory-size iomem 40
By default, the router allocates 25 percent of
DRAM to shared memory (used for data
transmitted or received by network modules and
WAN interface cards). If your router includes 16
or more ISDN BRI interfaces, you must increase
the amount of shared memory by entering the
memory-size iomem command. This example
increases shared memory from 25 percent to
40 percent.
Step 10
Router(config)# Ctrl-z
When you finish configuring interfaces, return to
enable mode.
