Ordering ISDN Service B-1
Ordering ISDN Service B
This appendix provides information on ordering ISDN service for PortMaster Office
Router users installing the OR-U, OR-U-AP, OR-ST, and OR-ST-AP in the United States
and Canada.
Ordering Instructions
Complete the following steps to order ISDN basic rate interface (BRI) service from
your telephone service provider:
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 Office Router 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 Office Router transmits data over B channels configured for both
voice and data as well as for data only, you can choose the less costly alternative.
3. Determine the ISDN switch type.
Ask your provider what type of ISDN switch you will be connected to.
