DID programming on Option 11C

DID programming on Option 11C

DID programming on Option 11C

Hello. We have never used DID's at our sites before - always an auto-attendant. How do I program a DID that is coming in on a digital PRI? Is there anything I need to verify on the PRI configuration? How do you specify the DID to terminate on the phone set itself- what would the key assignment be?  Thanks.

RE: DID programming on Option 11C

Are they dedicated DID trunks or is it a SmartTrunk for both incoming DID and outgoing calls?

If they are incoming DID. just program a route in ld 16 for DID.  I usually just set it as TIE, but that's just my preference.

You need to know how many digits the LEC is pulsing and make sure they match your extension range.  The calls will terminate themselves, unless they need to be redirected in the IDC table (ld 49) most times they don't.

RE: DID programming on Option 11C

If your PRI does not yet exist - open a MAC ticket with your service provider to install for you (there are a lot of things to configure - loop, dch, clocking, interface, protocol, channel types, calling line ID, 911). Never programm PRI dids as Tie.

If your route exists, you will have or need a number programmed as an LDN (ld 21 - prt, LDN). If the LDN is 4 digits you would then put the last 4 digits of the DID on the phone. If the LDN is 3 digits you would program the last 3 digits of the DID on the phone.

One other way is to use an IDC table. This converts incoming DID digits (whatever the LDN is) to different digits. For example did number 714 315 0830, LDN is 2222, IDC table for incoming digits would be 0830, outgoing digits would be 2830 - someones phone ext. IDC tables are built in LD 49, allowed in CDB LD 15, Assigned to route LD 16.

Reusser is absolutely correct.  If you set this PRI up and their is a problem, most of these Telco providers just sit back and tell you that their stuff is correct.  I do these all the time, and just about every time their is some little thing hosed up.  You wind up telling them what is wrong.  Poit is if you are not experienced programming PRI on Nortels you could be in for a trip!
