IBM SC30-3681-08 manual Using the V.25bis Network Interface, Adding V.25bis Addresses, 579

Chapter 41. Using the V.25bis Network Interface

The V.25bis interface allows routers to establish serial connections over switched telephone lines using V.25bis modems. This chapter describes how to use the V.25bis interface. It includes the following sections:

vªBefore You Beginº

vªCon®guration Proceduresº

Note: You can assign a destination name to a connection list and assign a destination number to each line in the list. When that destination name is called, the numbers in the list are tried one by one until a connection is made or the list is exhausted.

Before You Begin

Before you con®gure V.25bis on the router, make sure you have the following:

vV.25bis modems that support synchronous V.25bis commands and the 1988 ITU/CCITT V.25bis speci®cation.

vIf your modem does not automatically detect answer originate, you must:

±Con®gure the modem at one end of the link to originate calls.

±Con®gure the modem at the other end of the link to answer calls.

±Set up the modem on the answering end to auto-answer.

Con®guration Procedures

This section describes how to con®gure your router for V.25bis. The tasks you need to perform are:

1.Adding V.25bis addresses

2.Con®guring V.25bis parameters

3.Adding dial circuits

4.Con®guring dial circuits

Note: You must restart the router for changes to the V.25bis con®guration to take effect.

Adding V.25bis Addresses

You need to add a V.25bis address for each local V.25bis interface as well as for each destination. The V.25bis address includes:

vAddress Name. The address name is a description of the address. You can use any string of up to 23 printable ASCII characters.

vNetwork Dial Address. Telephone number of the local or destination port. You can enter up to 30 characters that are in the valid format of the connected V.25bis modem. For additional information consult your modem manual.

Note: The valid character set for telephone numbers as de®ned by the CCITT and supported by the IBM 2210 includes:

±The decimal digits 0 through 9
