Ordering Service

This appendix explains the basic principles of ordering ISDN service and establishing a connection between the Dialogic Digital Network Interface boards and the Network Termination Unit (NTU).

When ordering your ISDN service from a carrier, keep the following points in mind when talking to a service representative:

• Be specific when describing the kinds of service options you want. Your carrier may offer options that the carrier representative did not mention.
• Find out as much as you can about details of the turn-up process.
• Be sure to find out which aspects of service your carrier is responsible for and which aspects are your responsibility. Carriers may offer end-to-end coverage, or responsibility for the lines may lie with several different companies. Not knowing who to contact in the case of difficulties can delay repairs and impact productivity.
• Have the manufacturer's name, equipment numbers, and equipment registration numbers for the customer-site equipment you are installing or have installed.

You may want to consider hiring a third-party telecommunications or telephone consultant to coordinate service with a carrier. Or, you might delegate parts of the service acquisition process to others. Though these options may involve additional costs, the installation process is streamlined as a result of enlisting the help of someone knowledgeable about the service-ordering procedure.
