Chapter 3: Operating the system
Selecting the call type
Definition
The phone connection can use one of the following call types:
Standard Voice, which is a low-tariff voice connection compressed to
•
4.0 kbps
3.1 kHz Audio, which is a high quality connection used for Premium Voice
•
or G.3 fax
UDI or RDI (only on ISDN interface), which is used for G4 fax or data
•
In the web interface you can set up which type of connection to use by default
when you make or receive a call from the Phone/Fax or ISDN interface or from
an IP handset connected to the LAN interface. Standard Voice is selected by
default.
When connecting a fax to the Phone/Fax interface you must use 3.1 kHz Audio.
Example: If you always have a fax connected to the same Phone/Fax
interface you can set this interface to 3.1 kHz Audio only. This will
mean that if an incoming Standard Voice call is received, this
Phone/Fax interface will not ring.
When connecting a G4 fax or a modem to the ISDN interface in the
TracPhone FB500 system you must use UDI.
UDI and RDI are not available with the TracPhone FB250 system, so
Note
you cannot connect a G4 fax machine nor a modem to the ISDN
interface on the TracPhone FB250 system.
