Trunk Programs Overview See Flowchart 7-2 for an overview of the ISDN trunk programming procedure. o If you are installing all standard trunk groups, skip Program *16 (the default is for all standard TGs). o If you are installing BRI ISDN, use Program *16 to assign BRI type and Program 16 to assign BRI CO lines into trunk groups. o If you are installing PRI, use Program *16 to assign PRI types. Do not use Program 16. Do not change settings in Program 16 for trunk groups marked for PRI. Primary Rate Interface (PRI) Programming 1.Run Program *16 to define the ISDN trunk group type as: non-ISDN, Primary Rate Interface (PRI), or Basic Rate Interface (BRI). 2.For BRI trunk groups, run Program 16 to assign the trunk groups. Then, skip to Step 7. 3.For PRI, run Program *65 to assign B-channels. 4.For PRI, run Programs *66-1, *66-3 to define trunk groups parameters and channels. (Program 16 will be assigned automatically.) 5.To assign Call-by-call features (PRI only), run Programs *66-2, *66-4 to assign Call-by- call trunk groups codes and network ID. 6.For PRI, run Program *67 to assign call direction for ISDN trunk groups and call type capabilities allowed for each trunk group. 7.For BRI and PRI, run Program *68 to define the parameters for Calling Number to be presented for a call depending upon whether the ISDN trunk group uses DID, private numbers or use default number programmed in *68-2. 8.For BRI and PRI, run Program *66-5 to assign Listed Directory Numbers (LDNs) to channel groups and index numbers. Then run Program *66-6 to assign LDN channel groups to ISDN trunk ports. Then run Program *66-7 to assign trunk groups to each LDN. 9. Run Program *68-2 to define whether or not the system presents a “user” Caller ID when calls are made using ISDN services. This program also enables users to dial a code to send Caller ID or to block it. 10.For BRI and PRI, run Program *69 to define the parameters for Calling Number to be presented. Each phone can present a unique Caller ID number, such as DID or a private number. If neither is chosen, the default is the Directory Number entered in Program *68-2 for outgoing calls. 11.Run Program *64 to assign each ISDN trunk group to use DID/DNIS programming, or to provide Direct in Line (DIL) ringing for incoming calls. 12.See “ISDN Related Programs” on Page 7-3, and make the appropriate programming assignments.
