The general ISDN options are explained first.

ISDN General Menu CONFIG=>INTERFACE=>T1/E1(ISDN-PRI)=>ISDN

Parameter

Description

Main Phone #

Principal phone number assigned to the ISDN trunk line. Leave this parameter blank if this

 

number should not be confirmed by the router. This is recommended when the provider

 

does not send the trunk line number in the incoming call message.

Idle Timeout

Time, in minutes, for the connection to time out if there is no traffic. For this to work, any

 

status messages, like PPP's LCP Echo Requests, must be disabled. The value 0 disables

 

the timeout function.

T200

Data-layer timer. When the router sends a command, this timer determines how long it

 

should wait for a response.

N200

Data-layer number of re-tries. When the T200 period passes without a response, the

 

command is re-sent up to N200 times.

T203

When no messages are received for T203 seconds, an enquiry (RR or RNR) is sent.

At the end of this parameter list appears the menu for the dial-out table. It can also be reached by using the <ESC> key at any time during the parameter list.

Each entry is an association between a channel and the IP Address and Phone number at the other end of the connection. The router uses the IP information stored here in its routing table. When a packet arrives at the router, and the IP is listed in the dial-out table, the router will attempt a connection on the slot indicated using the associated phone number. The parameters for each entry are given next.
