6. To set up a second B channel for bandwidth on demand, enter the
load-threshold command to set the ISDN load threshold. The load
threshold determines the percentage of network loading at which
the second ISDN B channel is triggered. The value ranges from 1
to 255 (100 percent).
Router (config-if) 3 dialer load-threshold 128
In this example, the value of 128 means that when the first B chan-
nel reaches 50 percent of its bandwidth capacity (128 equals 50
percent of 255), the second B channel will be activated to assist
with the bandwidth load.
7. Enter the access-list command to configure the ISDN line to
come up whenever IP packets are to be sent:
Router (config-if) # access-list access-list-number permit-ip sourcerouter-
ipnetwork sourcerouter-subnetmask targetrouter-ipnetwork targetrouter-subnetmask
Router (config) # dialer-list groupnumber list access-list-number
8. Configure a static route to allow connectivity to the target router’s
local network. Enter the network number of the target router’s
local IP network and subnet mask, and the IP address of the target
router’s BRI port:
Router (config) 3 ip route targetrouter_ipnetwork subnetmask
targetBRIport_ipaddress
9. Enter the exit command to exit configuration mode.
10. Enter the copy running-config startup-config
command to save the configuration to NVRAM.
Configuring
Switched 56
This section explains how to configure the 4-wire 56/64-kbps DSU/
CSU WAN modules for switched 56-kbps circuit-switched service
The 4-wire 56/64-kbps DSU/CSU WAN module is configured for
DDS as the factory default, but it can be configured for either switched
56/64-kbps service or DDS.
Take these steps to configure the 4-wire 56/64-kbps DSU/CSU WAN
module for circuit-switched service, substituting the correct addresses
and host names as appropriate for your network:
