[asterisk-users] question on nortel CS 1000 PBX and PRI connection to built in PA system

[Dale Noll]

Hi,

Is the Paging on the Nortel connected to a trunk port or is there some 
device connected as a physical extension that answers the call?

Hopefully you have access to the nortel box.

I am going to assume that you are not very familiar with the nortel 
command interface. If I am incorrect, I apologize.

On the nortel, in ld 20, do a 'dnb' on the paging 'extension'

Assuming you are customer 0 and paging extension is 1234...
NOTE:  in sample below, nortel prompts are UPPERCASE, user input is 
lowercase.
--- snip ---
ld 20

REQ:  prt
TYPE: dnb
CUST: 0
DN    1234
DATE  <return>
PAGE  <return>
DES   <return>
--- snip ---

If the answer returned shows the TYPE as RDB, you are probably on a 
trunk line, make note of the Route number.

If the response says the TYPE is SL1, it is a digital phone or if the 
TYPE is L500 it is an analog phone.  In either case, it is a physical 
device that must answer the call.

If the 'extension' is a route, I would be interested in the RDB output 
for both the tie route and the paging route.

--- snip ---
ld 21

REQ:  prt
TYPE: rdb
CUST  0
ROUT  <route number>

--- snip ---

You can also monitor the D-Channel(DCH) while you attempt a call. You 
can use ld 96 for that.

There are commands for messages coming in on the DCH(MSGI) and messages 
going out on the DCH(MSGO)(That is O as in Out)

You will need to know the DCH number for the tie trunk.
Assuming the DCH is 0...

--- snip ---
ld 96
enl msgi 0
enl msgo 0

--- snip ---

You will see messages for any call in or out of the nortel on that DCH. 
  With this you can verify the calls are coming in and where they may be 
connected to if connected at all.

Turn off messages with:

dis msgi 0
dis msgo 0


Another thing I have run across is routing problems. If the * sends a 
call to nortel and nortel routes it back to * and * routes back to 
nortel....  This will sometimes exhibit a delay before * play error 
message.  In such an event, the nortel console will display an error 
code, but I cannot remember with one.

This could be an issue with steering codes in ld 87 FEAT=CDP.


I hope this helps.
Post any command output if you are still having problems.
