CHAPTER 3 SYSTEM DATA PROGRAMMING

ISDN Feature Programming

The next example details a local 7 digit call and will not used a Binary Facility Code.

CM8A4005>2 (dialed number)=001 (go to route pattern 000)

CM8A0000>1 (1st choice)=00210 (use LCR pattern 002 + trk route 10)

CM855>2=7 (maximum number of digits dialed)

CM8A5002>157=04 (Kind of called party=Local) (dialed number is 7-digit NANP, select Local) CM8A5002>158=01 (Called party Number Plan ID=ISDN/Telephony Numbering Plan) CM8A5002>159~161 are not used for this call.

CM8A5002>162=1 (Service) CM8A5002>163=NONE (not sending) CM8A5002>164 is not required for this call.

NOTE: These examples are provided to demonstrate the required programming. Always verify with the ISDN provider as to how local calls should be handled.

Features

Carrier Identification Codes (CIC)

In ISDN terms placing a long-distance call using the equal access carrier code is a feature. There are times when, depending upon the type of service provider (LEC or IEX), the PBX must contain the following programming to complete a long-distance call by using CIC numbers.

Currently all CIC numbers are three digits in length preceded by a 10. Example: To dial AT&T, a user dials 10288 + the long-distance number. The PBX must route the call based on 10288 or a portion of that number. ISDN complicates this process by identifying each CIC at the PBX level.

For example: Without ISDN the PBX is able to simply outpulse 10288 and the public network would provide connection to AT&T. With ISDN used for routing equal access calls, the PBX must translate the 10288 in its entirety and provide the network with four pieces of information as described below. The implementation of this feature is further complicated by the fact that this is only required by some ISDN providers and not others.
