Description
The line do not detect FAX automatically.
DVG-5112S uses T.30 as the protocol for fax transmission. The
parameter settings are the same as for voice transmission. However,
enabling the fax function will consume more network resources and
will affect transmission quality.
DVG-5112S uses T.38 as the protocol for fax transmission. T.38 is
used for better and faster facsimile transmission. It is recommended
to enable T.38 to gain better fax quality without setting fax and voice
parameter.
Choose T.30 Fax/Modem as the protocol for transmission if
DVG-5112S is connected to Modem.
Choose T.30 as the protocol for transmission. DVG-5112S only
accept the fax protocol of T.30.
Description
DVG-5112S sends the same FAX frame twice to get a high quality of
the FAX when the line is using T.38 Fax. It requires more bandwidth.
DVG-5112S provides G.711 and G.726 for T.30 fax transmission.
It is recommended to use G.711 for T.30.
It is to adjusts the jitter to receive fax packets. If the jitter range is too
large, it will delay fax transmission.
