DESCRIPTION

This configuration only works with dedicated inbound and outbound channels and was tested using a PRI with DID’s for voice and fax. The voice DID’s are 34xx and the fax DID’s are 35xx.  

Note:

The only downside here is if all your inbound channels are in use, the NBX does not return a busy signal so the inbound call gets a “ring no answer”. In a high volume environment, putting an Adtran Atlas 550 or FaxPress Premier Digital between the NBX and PSTN would be recommended.

The diagram below illustrates an example of an 8 port FaxPress where 4 ports are used for inbound fax calls and 4 ports used for outbound fax calls.

To configure inbound channels on the FaxPress:

1. Open the Properties of the FaxPress and open the Line Settings
2. Set the number of rings to answer to one (1).

To configure inbound channels on the NBX:

1. Analog line cards (ALC) must be used for incoming fax calls as analog terminal cards (ATC) do not support out pulsing DTMF tones.
2. Configure the ALC ports in a new extension list (i.e., Inbound Fax Channels) and check the “Cycle Extensions” checkbox. This needs to be done so the incoming faxes will rotate like a circular hunt group because the ports on the FaxPress do not reset as fast as the ALC ports and you will experience problems if you keep trying to use the same channel over and over.
3. Next you will need a C.O. simulator that will sit between the NBX ALC port and the FaxPress port to provide dial tone for the ALC ports. The ones we used are from Viking Electronics, Inc. Part number DLE-200B or DLE-300. www.vikingelectronics.com
4. Next you will need to modify the dial plan to route the incoming fax DID’s to the new extension list and out pulse the DTMF tones after the FaxPress answers.

Below are sample dial plan entries on doing this. As you see, fax DID 35xx comes in and is routed to the new extension list *0009 which are the line card ports. Because the C.O. simulator is providing dial tone and the ports are online, the port goes off-hook, which causes the C.O. simulator to ring the FaxPress. The commas are putting pauses before the fax DID to allow for this process and after the FaxPress answers the fax DID is out pulsed as DTMF tones. Start by using eight (8) commas and you may need to modify this further for your environment.

To configure the DLE 300:

A. DIP Switch Programming

B. Internal Jumper Programming

NOTE: 

If you are receiving data errors, low baud rates, and your DID configuration is not receiving all digits or no digits at all, we suggest moving the jp5 to jp6 jumper inside the DLE 300.

See below for jumpers 5 and 6 detailed descriptions:    

JP5/JP6

Description: The two device ports are directly connected together offering no signal loss between the devices. Move Shunt from JP5 to JP6 to attenuate the audio volume between the devices by 9 db (typical of most CO lines).           

To configure the DLE 200B:

A. DIP Switch Programming

B. Internal Jumper Programming

To configure outbound channels on the NBX:

An Analog Terminal Card is used to provide dial tone to the FaxPress and outgoing faxes will be treated as any other outgoing call. You may need to use an outgoing CLI pre-translator for the ATC ports that will present your main fax number as caller ID.

NOTE: 

If you are receiving data errors, low baud rates, and your DID configuration is not receiving all digits or no digits at all, we suggest moving setting switch 3 on the face plate to the on position on the DLE200B.  See below for detailed description of switch 3.

Description

3-on/up Decreases audio volume by 9 db may increase fax/modem connection speeds and help eliminate data errors

3 down/off Standard audio volume (factory default)
