Max Extension Digits
This parameter is used when the "Routing" parameter is set to "DTMF Digits" or a PBX mode
code. Enter a value that matches (in length) the number of DID digits to be passed by the
line/PBX to the FaxFinder Fax modem port. The supported range (length of DTMF string) is from
1 to 15 digits.
Routing
This parame
ter only applies to inbound Fax Calls (calls from the PSTN). This parameter selects
whether or not the FaxFinder modem should look to the line (e.g. PBX ext. line plugged into the
modem) for DID routing information in the form of DTMF digits. The selected Routing parameter
directly effects how certain fields of the "Inbound Routing" menu should be set up.
There are 3 basic options: POTS Line, DTMF Digits or a PBX specific Mode Code.
POTS Line:
POTS Line routing configures the modem to act in a more traditional Fax answering
role - where the modem does not look for DID routing information from the line/PBX. After the
modem receives the Fax, the FaxFinder delivers the Fax based on the option(s) defined for this
modem (line number) in the "Lines" section of the "Inbound Routing" menu.
DTMF Digits:
DTMF Digits routing configures the modem to listen for DID Routing information
from the PBX/line (upon going off hook after the first ring). The DID (direct inward dial)
information needs to be a string of DTMF digits. This string is normally associated with the fax
number dialed by the originating side fax device. DID information is also referred to as Called
Number information. Upon hearing the expected number ("Max Extension Digits" parameter) of
DID digits the FaxFinder modem will then make fax answer tones to begin the reception of the
incoming fax. After the modem receives the Fax, the FaxFinder scans the "Recipients" section in
the "Inbound Routing" menu, looking to match the DID number it heard with entries in the
Recipients table - to determine delivery options.
PBX Mode Code:
PBX Mode Code routing is the same as DTMF Digits, except that the string of
DTMF digits/tones that comes from the PBX contains additional information not used by the
FaxFinder (information normally intended for a station phone). The FaxFinder needs to know the
format of the incoming mode code to be able to identify and extract the DID extension number
imbedded within it.
Note: When DTMF Digits or PBX Mode Code routing is selected, the FaxFinder modem will listen
up to 15 seconds for all of the expected DID routing information. If none or only a portion of the
expected digits are detected, after 15 seconds the FaxFinder modem will declare a timeout and
then proceed to make fax answer tones. After the fax is received, the fax will be delivered as if
POTS Line is the selected routing technique.
Fax Direction
This parame
ter defines how the FaxFinder fax server is to use this modem line with regards to
fax call direction. Should the FaxFinder use this port to dial from and send out faxes (Outbound),
or should it only expect to receive faxes on this line and not use it for sending (Inbound), or
Both? Set this parameter in conjunction with how the equipment/analog line connected to this
port is to function in this same regard. If the FaxFinder port is set to a Fax Direction of
Outbound, but the PBX/Telco line connected to this port sends a call/ring to this port, the call
will go unanswered.
