ISDN Line Checklist
The recommended ISDN line provisioning for your U or S/T interface ISDN line is:
•
ISDN CO Switch type:
•
U Interface: AT&T 5ESS and Nortel DMS100 or National ISDN NI-1
•
S/T Interface: ETSI NET3
•
Circuit Switched Voice and Data on both B channels (B1 and B2).
•
No call features are required on any B channels.
•
Must be capable of 56K or 64k Synchronous Data Calls, Clear Channel
Note: Specifications are subject to change without notice as technological or manufacturing
changes warrant.
•
Ensure you have the proper ISDN line installed at the Remote module's site.
•
Ensure you know the SPID/DN numbers (U Interface), TEI type, and Connect Rate (56K or 64K).
You obtain this information from your local ISDN service provider when the ISDN lines are
installed. Note, that the S/T interface uses MSN numbers (Multiple Subscriber Number) instead of
a SPID or DN.
•
Ensure that you have registered the ISDN lines with your long distance carrier for ISDN DATA Ser-
vice, if required.
