This article describes ISDN ordering and configuration parameters for QuickTime Conferencing H.320/ISDN products when used with United States telephone lines.

This is a summary of the types of ISDN lines supported by phone companies. All Apple QuickTime Conferencing H.320/ISDN products work with all ISDN switch types (AT&T, Northern Telecom, and Siemens). The ISDN lines offered by your phone company may differ from region to region. You may be given an option of a custom line or National ISDN-1. If you are given a choice order the National ISDN-1 configuration.

Follow the guidelines below when ordering the specific type of line you choose, or copy this sheet and FAX it to your ISDN service provider to expedite the ordering process.

National ISDN-1

1. Circuit-Switched Data/Voice (CSD/V)
2. Circuit-Switched Data (CSD)

You have a choice of whether you want, or do not want voice capabilities.

Maximum Number of B-Channels: 2

TEI assignment: Dynamic

Packet Mode: No

Number of Call Appearances: 1 if you order CSD/V, otherwise none

Terminal Type: A (Basic call terminal)

Protocol Version Control (PVC): 2 (on Northern Telecom switches)

EKTS: no requirement

Optional: Order Call Forwarding Busy for both B-channels if you have ordered an ISDN line with 2 Directory (Telephone) Numbers. This forwards a call to an open B-channel if the called B-channel is in use.

Note: For 5ESS National Internet (NI) -1 lines it is possible to order a NI-1 ISDN line with only one Directory Number. This circumvents the issue of having to forward calls to an unused B-channel. For Northern Telecom DMS-100 ISDN lines (both NI-1 and Custom) you must have two Directory Numbers, therefore the call forwarding option is desired.
