Reference Guide for the Model XM128 ISDN Digital Modem

SPID Setup for North America

SPID numbers are needed unless your switch type is AT&T 5ESS with Point-to-Point Protocol. The ISDN switches use SPID numbers to represent the subscribed network services. Each SPID corresponds to one terminal end point identifier. Different switches might provide different rules for the SPID number format. You should get the SPID number from your local telephone company. To program your SPID number(s), use AT commands (n is the SPID provided by your telephone company) and follow these steps:

1.Type ATSPIDO=n and [Enter].

You should receive the following response:

OK

SPID Correct!

It might take up to 30 seconds for the response. This response indicates that the SPID number was accepted. If a second SPID is required, go to step 2.

2.Type ATSPID1=n and [Enter].

You should receive the following response:

OK

SPID Correct!

An error condition is present and it indicates that an incorrect SPID number was entered if you receive the following response:

OK

SPID Error!

A general failure is indicated if the ISDN line is not connected to your Model XM128 modem or if you select the wrong switch. The SPID number was not verified if you receive the following response:

OK

The D LED lights when the SPID(s) are entered and verified. If you are not able to get the SPID(s) to accept correctly, recheck all cable connections before verifying the number(s) with your telephone company and reentering them again. If the D LED still does not light, the telephone company should make sure the line you ordered has been correctly set up.
