AFTER-DIALING used on a fax server with POTS lines

[dmpd]

Anyone out there ever heard of this arraingement called AFTER-DIALING. This is used with a fax server?
-------------------------
DTMF Routing with Telecom Equipment



The sending fax machine dials the number for the TR114.
PABX rings the TR114, and plays ringing tone to the sending fax machine.
TR114 answers the call (goes off-hook).
PABX senses this, and sends down the last few digits of the dialed number as DTMF tones (usually the last 3 or 4 digits of the phone number).
Application software collects these digits and looks up in a table, to determine who or where to route the incoming fax.
PABX connects the sending fax machine to the TR114.
The fax is then received and routed to the correct location.
System Requirements

The PABX should:

Provide a standard loop-start line for the TR114. (Loop-start is often referred to as "POTS", for Plain Old Telephone Service.)
Be capable of assigning a sub-group of numbers to a single port. When any number within the subgroup is dialed, the call is automatically routed to the same port.
Be able to send down the dialed number, or part of the dialed number to the port as DTMF digits after the call has been answered. This is commonly called AFTER-DIALING, and is a feature provided for the PABX to communicate with other peripherals, such as voice mail.
Send the first DTMF digit no earlier than 200ms after the call has been answered by the TR114. Ideally this parameter would be programmable, or significantly longer than the 200ms required by the TR114 to allow for delays within the application.
Many systems are capable of sending down a pre-defined number of digits, and stripping off any leading digits. For example, a typical system can be programmed to send down the last 4 digits.
---------------------
I have never heard of this, AFTER-DIALING. Once a POTS line answers a call the call is complete. I can program a trunk route to send the digits but the customer equipment will only work with pots lines and will only answer on ringing current.

sounds like you'd insert a xx second pause between sending numbers??

I am not familiar with that service. How could you make that happen? After the POTS lines is answered the call would be complete? No more digits.

 

[phonz1]

a pause is normally an asterisk or a "p", and sends the first string of digits, pauses and then sends the next set. You would need to talk to your fax salesperson for more info... the pause thing has been done for years

 

[dmpd]

The customer wants the initiator to only dial the 10 digit telephone number. I believe you are talking about dialing the 10 digit number then pause and continue dialing another 3 or 4 digits in the dialing string programmed in the fax. No, I ask that question.

 

[phonz1]

well, I am out of ideas then, PBX's normally like ground start pots lines... Maybe you should consult your vendor for the info

The only way that I have seen a Brooktrout Fax Server work is with DID numbers either T1 or copper then the last 4 digits is sent to the Fax server through CDP

That is exactly what I told the csr. His fax vendor assured him that we were wrong and that a pots line would serve this need. I told him that we could either give him a DID or a Tie line interface to provide the digits. Thanks for the Help. I just wanted to ask more techs if they had ever heard of an interface to serve this need.
