Configuring the D/T 2793/4793 Internal Modem for Facsimile Support

Resolving The Problem

The D/T 2793 / 4793 modem is a V.92 Socket modem. It has one RJ11, which can be used for a fax port, as well as an RVX port (RS232) in which you can attach a 7852-400 or MT5600BA modem to have an additional line for faxing.

NOTE: The MT5600BA modem MUST have an IBM part number on the bottom and be at firmware level 1.702M for it to work successfully. Any other firmware version will not work. Newer MT5600BA modems without an IBM part number have a higher firmware level. A lower version of the firmware cannot be loaded on the modem.

Requirements:

o	R520 or higher Operating System
o	R520 or R570 IBM Facsimile Support, product 5798FAX
o	Current PTFs found in Document New PTFs for Facsimile Support. To link to document New immediately, click here .

Supported Functions:

o	ECM (Error Correction Mode)
o	TSI (Transmitting Identifier) Banner
o	V.34 speed

Unsupported Functions:

o	IOP-less systems. Refer to the following Rochester Support Center knowledgebase document: New, Fax Not Supported on IOP-Less IOA:

Before configuring, run the CHGNETA MDMCNTRYID(xx) command, where xx is the country code (for example, US for United States).

Note: If you do not run this command, the controller and line will fail when configuring.

If you are transitioning to the 2793/4793 and have previous configurations, delete them using the DLTFAXD command.


Configuring the Internal Port for Faxing

On the operating system command line, type the following:

CRTFAXD LINKTYPE(*IMANALOG) LIND(FAXLINE1) RSRCNAME(xxxxx)

where xxxxx is the resource name, for example, CMN04 as shown below. Press the Enter key.

Configuring the RS232 External Port for Faxing

On the operating system command line, type the following:

CRTFAXD LINKTYPE(*ASYNC) LIND(FAXLINE1) RSRCNAME(xxxxx)

where xxxxx is resource name, for example, CMN05 as shown below. Press the Enter key.

If you are unsure of the resource name, run the WRKHDWRSC *CMN command to find the 2793 resource.

Example

CMB04 284C Operational Combined function IOP
  LIN12 2793 Operational Comm Adapter
   CMN04 2793 Operational Comm Port <--- Resource Name needed
   CMN05 2793 Operational V.24 Port <--- Resource Name needed

Note: CMN05 is actually an RS232, but it can show up as a Comm Port. Only when an external modem is connected using the RS232, and an IPL is performed, will the resource show up as a V.24 Port.

After completing the CRTFAXD command, the following command is needed:

ADDFAXCRD FAXD(FAXD01) FAXCRD(FAX1) FAXTYPE(*BOTH) ECM(*ON)

Confirm the line is in a Connect Pending status.

Use the STRFAXSPT command; it will bring the line ACTIVE.
