Setting Up ISDN Service 2-13

3.Type of switch configuration used on your line. You must receive this information from your telephone company to prop- erly configure the Netopia ISDN Modem. The switch should be one of the types supported by the Netopia ISDN Modem:

■AT&T 5ESS custom

■Northern Telecom DMS-100 or Siemens EWSD

■AT&T 5ESS

4.Directory numbers and SPID (service profile identifier) num- bers. This information may be provided to you at a later time, after your line has been set up. There may be one or two direc- tory numbers, and one or two SPIDs. If the switch on your line is an AT&T 5ESS custom point-to-point, you will receive no SPIDs. It’s very important that you record this information accu- rately.

Note: Regardless of the number of directory numbers and SPIDs you receive, your line should be configured to allow the Netopia ISDN Modem to use both B channels at once.

5.Circuit ID number. Your line has a unique physical address called a circuit ID. You should obtain this number from your tele- phone company and record it on the worksheet. The circuit number can be useful for locating your line and its associated circuit in case of a problem.

6.Long-distance company to be used on your ISDN line. When the Netopia ISDN Modem makes long distance calls on your ISDN line, you will be billed by a long distance telephone com- pany. Make sure that you have the long distance company of your choice.
