2-14 Netopia ISDN Modem User’s Guide
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 Interface (BRI).
2. Ask the telephone company representative what type of switch
the company will use for your line: AT&T 5ESS custom, North-
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 Northern Telecom
DMS-100.
3. Locate your telephone company’s ISDN switch type in the table
below. Provide the switch parameters to the representative.
