Number of Digits Sent on DID, 4, 7, 10, etc (MICS Systems) 5

[GHTROUT]

Scenario is a bunch of MICS systems (each with PRI) that are slated to be fork-lifted and replaced with Avaya. The new Avaya will be part of a larger dialing plan, with all phones being on a 7-digit dialing plan.

Today, all the Norstars receive 4 digits from the CO on DID calls. With the new Avaya, we will need 7 digits. I want to have Telco start sending 7 digits prior to the new Avaya system going in. Can the Norstar handle this like our larger CS1000 systems referred to here? thread798-1704129

Will I need to change anything in the Norstar? Anything I need to know before I get in too deep?

I can't speak for the American Norstar systems, but I know that in the UK, we are able to tweek the target lines to except different received digit lengths from the Telco OK.

All the best

If it's working, then leave it alone!.

you can change rec'd digit length to 7. you wiil have to reprogram all target lines.

Since PRI DID does not send the digits one at a time (like analog does), and my experience with larger systems is it counts from right to left, are we "certain" we have to change the target lines just because the Telco is submitting all 7 digits?

You're right.

You can program the system to use less digits than the CO is sending. The last digits are considered (and the first digits are ignored).

Multimedium: Who is the You in "You're right" Sadly, this is not a threaded forum.

So your challenging the reasoning of the previous poster? Are you saying target lines would NOT have to change if all I did was have telco send 7 digits rather than 4.

You" is the one who started the thread. ;-)

You, GHTROUT, have two options here. You can ask the CO to send 7 digits and either:

1. Change the Received Number Length to 7 digits on the Norstar. By doing so, you will need to reprogram the Received Number of all the target lines. If you use the Auto DN or the DISA DN, you will have to reprogram them too. That is because the system clears the existing Received Numbers when the Received Number Length is changed.

2. Don't change anything on the Norstar. The system will consider the last 4 digits sent by the CO (and will ignore the 3 first digits).

 

[GHTROUT]

Outstanding! Thank you. Since the Norstar is being forklifted, the motivation to change to 7 digits is on the new Avaya, which will have all 7 digits DNs built in it from the start. In that case, I can have telco change to 7 digits today, do nothing to the Norstar, then when I move the PRI from the Norstar to the Avaya, it will work without waiting on some order to complete at the last minute.

Here is an update - we found out Telco was already sending us 7 digits, so clearly, it works just fine even with all the target lines defined as 4 digits.

The Norstar will remain a 4 digit system. The replacement Avaya system will have all 7 digit DNs.

Thanks again everyone!

Easy to remember rules;
Norstar/BCM - You can set the system received number length to match or be less than what Telco is sending, but you can never set the received number length to more than what telco is sending.
Example ... I buy DID block 555-1200 thru 555-1299 and Telco is send me 7 digits.
The system Received Number Length can be up to 7 digits.
In this example I would use a 3 digit received number length since I plan to use the 500 as my start DN and I will use 1 as a park prefix.
If I set my received number length to anything above 7, the calls would fail because the system would eternally be waiting for one more digit to determine what to do with the call.

Hope this helps clear it up a little.

If I set my received number length to anything above 7, the calls would fail because the system would eternally be waiting for one more digit to determine what to do with the call.

Actually, the calls would be routed to the prime set for the trunk. If there is no prime set for the trunk, the caller usually hears a recorded message.

FYI you can increase the public received digit lenght and it will not wipe the target lines. If however you decrease the received digit lenght it will wipe the target lines. Never knew this until recently and tried it in the lab.

How is this possible? The system has no way to know which digits to add to the existing Received Numbers.

 

[SS67]

If you look at the definition of the public received digits field it says (maximum number of received digits) not the exact number of received digits. So if this field is set for 10 you can still be allowed to enter only 7 for example. Try this in your own lab. You will see what i mean.

What you say applies to BCM. This is the Norstar forum.

On Norstar, there is no distinction between Public Received Number and Private Received Number. All remote users, whether they are on the private network or on the PSTN, use the same Received Number.

On Norstar, the Received Number Length can be from 1 to 7 digits long. The exact length must be used when programming target lines. For example, if the Received Number Length is set to 4 digits, a Received Number with exactly 4 digits must be entered; there can't be more or less digits. This explains why all the existing Received Numbers are cleared when the Received Number Length is changed.

No you will not have to change anything if the telco starts sending 7 digits.
The option for received digits set in the MICS determines the number of digits you must enter when assigning target lines and and it won't accept anything less or more in the GUI.
As long as the telco sends at least that many or more digits the norstar will work just fine.
I have pri's working with 3 digit target lines and the telco is sending 7 digits
I have pri's working with 4 digit target lines and the telco is sending 7 digits and they all work just fine.
If your telco is only sending 4 digits now and your norstar is set for 4 that's OK too.
If the telco suddenly starts sending 7 digits it will not affect the operation of the norstar because you have set it to only look at last 4 digits
