Trunk Programs Overview
See Flowchart 7-2 for an overview of the ISDN trunk programming procedure.
♦ If you are installing all standard trunk groups, skip Program *16 (the default is for all standard
TGs).
♦ If you are installing BRI ISDN, use Program *16 to assign BRI type and Program 16 to assign
BRI CO lines into trunk groups.
♦ 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.
