I'm trying to assign a DID to an extension, PBX is using a T1 trunking, what forms do I need to use? Thanks

Start with form 15.

M =digits expected
N =digits absorbed
X =digits inserted

If you can't match the DID to the ext in this form, then use X to insert speed dial access code, and point it to the Abbreviated Dial tables in Form 31.

Form 15 displays bay 4 slt 06 cct 01 thru 23 cos13 cor 5 ten1 N4 M2 X4 cpn 10 tr nun 1-23. All fields are the same. All extensions with DID's are in the 400-420 range. Need to understand how to land a DID to an extension and can I have 2 DID's ring at 1 extension?

the extensions are in the 400-420 range, what are the DIDs, do they match 400-420, are they completely different? Take a look at form 31, do you see extensions in the speed dials. what is the speed dial access code. Many ways to do this.

So, your system is programmed to expect 4 digits, the system is removing the first two digits and the system is adding the digit 4 to the two remaining digits. My guess is that the telephone company is sending XX00 to XX20. The system knocks off the first two digits and adds the digit 4. Now, the question is what is your numbering scheme for your extensions? If it is NOT 4XX, then what is the access code for your Abbreviated dial numbers? Look in form 03 for that.
