Ordering ISDN Service        D

Call your local telephone service provider to find out about ISDN service availability, pricing, and features. Typically there is an ISDN installation cost, a monthly flat-rate service cost, and usage costs.

Ordering Instructions

1. Call your local service provider to find out about ISDN BRI service availability, pricing, and features.
   

   Typically you are charged an ISDN installation cost, a monthly flat rate for service, and usage costs.

2. When ordering channel provisioning, compare the costs of circuit-switched voice/circuit-switched data (CSV/CSD) service and CSD-only service, and select the less expensive service.
   

   Although Communication Server ISDN models can be used for data transmission only, many ISDN providers offer data and voice service at a lower rate than data-only service. Because the Communications Server transmits data over B channels configured for both voice and data as well as for data only, you can choose the cheaper alternative.

3. Determine the ISDN switch type.
   

   Ask your provider what type of ISDN switch you will be connected to.

4. Check the switch type and refer to one of the tables in this appendix for switch type translations.
   

   Fax or read the appropriate table to the sales representative.

   • National ISDN-1 or NI-1 Compliant, see Table D-1 on page D-3

1. Choose a service provider for long-distance ISDN service.
   

   Staying with the telephone company that provides your existing analog
   long-distance service might be easier than choosing another carrier, although this is not a requirement.

2. Configure your site wiring to support ISDN service.
   

   Ask your provider what additional wiring is necessary to support ISDN on your premises.

   Depending on your existing wiring, you might need to have an extra pair of copper wires brought to your premises or additional inside wiring installed.

   If your ISDN wall jack is an RJ-11 jack (four pins, like a standard telephone jack), use an RJ-11-to-RJ-45 cable. If it is an RJ-45 jack (eight pins), use an RJ-45-to-RJ-45 cable.

3. Get your service profile identifiers (SPIDs) and directory numbers.

You need this information to configure the Communication Server.

The SPID identifies your equipment to the ISDN switch. Directory numbers are the telephone numbers assigned to your ISDN B channels by the telephone company.

To configure the ISDN switch type, SPID, and/or port directory numbers on the PortMaster, see the chapter on ISDN connections in the Configuration Guide for PortMaster Products.
