General ISDN line configuration
What if your telephone company does not recognize the Netopia
ISDN Modem? You can still use the ISDN Worksheet, but follow
these steps:
1. Ask for a standard Basic Rate Inter face (BRI).
2. Ask the telephone company representative what type of switch
the company will use for your line: AT&T 5ESS custom, Nor th-
ern Telecom DMS-100/Siemens EWSD, or AT&T 5ESS. Note
this information on your ISDN Worksheet for later use.
Note: NI-1 can appear on an AT&T 5ESS or a Nor thern Telecom
DMS-100.
3. Locate your telephone company’s ISDN switch type in the table
below. Provide the switch parameters to the representative.
