IBM SC30-3681-08 Number to congure the dial circuit. For example, Are not supported over Isdn

Using ISDN

To add a dial circuit, enter the add device dial-circuitcommand at the Config>

prompt. The software assigns an interface number to each circuit. You will use this

number to con®gure the dial circuit. For example:

Config>add device dial-circuit

Enter the number of PPP Dial Circuit interfaces [1]?

Adding device as interface 6

Base net for the circuits(s) [0]?

The number of dial circuits that can be con®gured depends on the total number of

parameters to be con®gured and the size of the resulting con®guration ®le.

Note: Dial circuits default to point-to-point (PPP) protocol. To change the dial circuit

protocol to Frame Relay, enter the set data-link fr command at the Config>

prompt. To change the dial circuit protocol to X.25, enter the set data x25

command at the Config> prompt. Other data-link types (SDLC and SRLY)

are not supported over ISDN.

Con®guring Dial Circuits

This section describes how to con®gure a dial circuit.

1. Display the Circuit Config> prompt by entering the network command

followed by the interface number of the dial circuit. You can enter the list

devices command at the Config> prompt to display a list of the interface

numbers con®gured on the router. For example:

Config> network 6

Circuit configuration

Circuit Config>

2. Map the dial circuit to an ISDN interface. Use the set net command. The Base

net is the ISDN interface number. (This is needed only if you are changing the

base net.)For example:

Circuit Config> set net

Base net for this circuit [0]? 3

Note: If the dial circuit data link type is X.25 or the base net switch variant is

I.43x or channelized, the following steps (3-11 on page 624 ) do not

apply.

3. Specify the address name of the remote router to which the dial circuit will

connect. You must use one of the names you de®ned using theadd

isdn-addresscommand. For example:

Circuit Config> set destination

Assign destination address name []? baltimore

4. Con®gure the dial circuit to initiate outbound calls only, accept inbound calls

only, or to both initiate and accept calls.

Use the set calls command. For example:

Circuit Config> set calls outbound

Circuit Config> set calls inbound

Circuit Config> set calls both

Note: For WAN-Restoral operations or dial-on-demand applications, you

should set up the circuit for either inbound or outbound calls.

5. Specify the timeout period for the circuit.

Use the set idle command. If there is no traffic over the circuit for this

speci®ed time period, the dial circuit hangs up. To con®gure the circuit as a

dedicated circuit, set the idle timer to zero. To con®gure the circuit to dial on

demand, set the idle timer to a value other than zero. The range is 0 to 65535

and the default is 60 seconds. For example:
