Program *66-2 Overview

The facility code and service parameters will be supplied by the ISDN carrier at the time the ISDN lines are ordered. Standard telephone services (POTS) will not have a Facility Code, nor a Service Parameter.

The Call-by-call feature enables individual PRI B-channels to be shared among various types of services specified by the customer, rather than having to dedicate each channel to a particular type of service. The Call-by-Call feature can reduce the number of circuits required to access various services, especially if various services have different peak busy periods.

In a future release, the minimum and maximum number of B-channels allocatable to any type of service can be assigned. Each of these values can be set for three time periods during the day. With these values, calls can be rejected if they exceed the maximum number subscribed for that service or they can ensure that a minimum number of channels remain available for incoming calls. Thus, the system can be used to provide an optimum service to meet the objectives of the business.

Call-by-Call services can be specified to map Strata DK capabilities to network services such as DID, Tie, FX, WATS, 800, etc. These services could be provided via the local telephone carrier or be connected to any ISDN inter-exchange carrier.

A table listing all valid DNs is provided for identifying the outgoing calls or alternatively a specific number or DID number. These may be used for identifying the call on a per station basis to allow calls to be billed to a selected service or station. All numbers used for identifying the call must be subscribed from the providing service or the call will be rejected by the provider.
