Ericsson internal routing module

To use direct routing on Ericsson MD 110 exchanges it is necessary to purchase additional specialized software module. Its installation is located on the installation CD in \faxchnge\i386\Ericsson_DIR\setup folder. Here you can also find direction for manual installation and some usefull information (00Readme.txt).

After installation it is necessary to configure your phone exchange:

The exchange must be configured to "Voicemail" mode. Such a configured exchange has a number of physical lines (connected to the fax card, so called VOICE CHANNELS (VCH)) to which is possible to re-route other virtual lines.

The exchange passes data about individual re-routed calls to the FaxChange server through serial port. Ericsson DIR module delays incoming fax processing by about 40 seconds. This ISN'T error but feature.

The serial port must be configured to the following mode: [9600, 7, E, 1]

Commands for the exchange

Configuration of the serial port and voicemail mode:

icfui:icuind=0,equ=1-1-42-0,rate=9600,dtmt=5,updfcn=no,parity=even,ccheck=yes,txc=yes,filler=48;@/EXE/

(this is one line!)

Configuration of individual channels:

vmfui:icuind=0,vmf=extn2,pofmt=2;@/EXE
vmpoi:icuind=0,grp=303;@/EXE
vmpoi:icuind=0,dir=302,port=01;@/EXE
vmpoi:icuind=0,dir=304,port=02;@/EXE

(This creates two VCH (voice channels), the first with number "01" on line 302 and the second "02" on line 304).

Problem solving

If incoming faxes aren't delivered after Ericsson DIR instalation, go to fax\IN folder. Some *.ecs files should be here is it true? And do they stay here more than one minute? If yes, Ericsson DIR doesn't work.
If faxes are delivered but PABX is wrong, there is also problem in Ericsson DIR module.

In both mentioned cases first set logging level to 3 and search for problem in eventlog.

Another step is to run Ericsson DIR module in debug mode. Stop FaxChange.EricssonDIR service and start bin\ericson.exe executable from command prompt with /debug parameter, i.e.

    Start menu -> Programs -> Command prompt
    c:
    cd \faxchange\bin
    ericson.exe /debug

If you dial a number of any virtual channel, information like this should be written on the console:

    received code : 83003010030001
    internal call. redirected from line 301 to [ VCH 01, line 0 ]. PABX = 300

It signals calling from line 301 to virtual line 300, vhich was redirected to VCH 01 (channel 0 from viewpoint of fax card).

If you dial directly number of VCH (no redirection), similar information will be written:

    received code : 820030101
    internal call. from line 301 to [ VCH 01, line 0 ].

It signals calling from line 301 to VCH 01, what is channel 0 on the fax card.

Fax card channels are stated in way how Ericsson DIR module thinks they are (according assignment in data\ericsson.ini file).

If you need to discover to which line you are calling in real, check content of fax\IN folder after fax card answers the call. File with name in form NNNNNNNxLL.tif appears here, where LL is fax line number. (So filename in first example above could be for example 342rt93x00.tif).

If you still can not solve the problem, set longer screen buffer for console window (see here), receive some faxes from direct calling to VCH line and from redirected call to virtual line, then select full content of console window, copy it to clipboard and send by e-mail to our support department.
