Installing DID Service on a Norstar

[WaltNC]

I am going to have DID service install on a new Norstar MICS. Where is the association between the incoming DID number and the target number made? What determines where calls to the DID numbers will appear on the sets?

Hope you have a trunk module,expantion card and DID cards.
You have to build the target lines and they should start at line 157 enter the public recived numbers and prime set-that is the set you assinging the line to,then in sets assign the aossiciated lines to the sets.

Thanks for your reply. We do have the expansion module,expansion card and DID trunk cards. What determines what physical button the line will appear at on the set

a bit more info:
you can put the DTI Card in slot four or three the first DTI on a system should be in slot four (all the way to the right) this makes the trunks 1-24.
you will need a service cartridge or a combo service cartridge in slots 1 or 2 (Slot 2 is the first use slot and if you have a fiber expansion cartridge or combo cartridge they must go there, if you don't have either of those two then put the service cartridge in slot 2)
You will need a PRI Enabler keycode if you are using an ISDN PRIme, If just a straight up T-1 (channelized) then you will not need this.

the Target lines start at line 157 but you don't have to use the target lines up sequentially. I have found several systems where the original installer had started with line 221 and then matched the target line to the DN Number as a way of keeping the numbering straight. your choice.

like noted above the received numbers do not have to match the DN but if you get lucky with the telco that is great.

DID cards can only go in a Trunk module not the MICS cabinet.

Thanks for the replies.

All of the programming related to target lines in jerry's post valid, whether you're using analog did's, or a PRI.

I have just installed copper DIDs (!) on a Norstar MICS, 6.1. I have the target lines built, and assigned to the sets, but when I call the DIDs, it does not ring the set. I can hear the call hitting the Norstar, but it still does not ring the set. What am I missing? I have for example, x4251, which is DID xxx-4251. Target line 168 is set to receive digits 4251. Prime set is 4251.

 

[RPMcMurphy]

Also, when I call the 7 digit DID, I don't get ringback.

Need to verify how many digits the telco is sending.

 

[Deweyhumbolt]

You won't get ring back until your switch receives the correct digits. Polarity is important with DID's, if reversed you will not see the wink.

You can test w/o telco or the PSTN. Put your buttset on the 66-block which attaches to you DID card and dial the 4 digit Target Line #, it will ring the telephone if programmed correctly. Thus, you can rule out, you being the issue.

Along with what Deweyhumbolt said, the butt set can also be left in monitor mode, clipped on the DID trunk at the 66 block. When the call is placed, you can "hear" the process and count the digit string.

Old phone guys (like this one) can tell what digits are sent by hearing the MF tones.

Overall, you can at least know that the wink start is operational and get a handle on the amount of digits sent.

Prime set assignment in a target lie for a specific extension will ring the intercom key for that extension. Be sure there are intercom appearances to accept the call.

Once a target line is programmed, it can be assigned to appear, appear and ring, just like regular analog positions.

Key: like others have stated:
1. Be sure of the DID programming from the Telco order. (Wink, Immediate, number of digits out pulsed, etc)
2. Be sure the DID cards are programmed accordingly
3. If Wink, I always went off hook with my butt set on each DID position on the equipment 66 block prior to the Telco jumper placement. That way I knew there was proper connectivity when I heard the card respond to my off hook condition.
4. double check all target line programming steps. One reversal of a digit string can through you for a loop. Keep a note on the programming for a record to fall back on in the future.
5. make sure the set has intercom paths if assigned as a prime set in the target line. (DID can also be used for a main number and routed to a receptioist position. In this case simply program multiple intercom appearances for the talk paths needed for the position.)
6. watch for digit conflicts. A received digit string will not fully program if the leading digit of the string conflicts with existing DN or access codes (I.E.: "9"xxx)
7. When assiginig the laines and target lines to a set, they will appear in the order they are programmed. You may need to use the F81? or F*81?, (can't remember which) to move and reaarainge line positions using the "from" "to" method.
If you are certain on all of the above, DID should be properly installed and working.

If not, double check and keep it simple. The hardest cases of trouble all to often get resolved by the easiest most obvious reason once it is discovered.

Thanks T1 Guy.
