Chapter 4 - MultiFRAD Software
Changing Voice/Fax Channel Parameters
The Voice/Fax channel parameters include the interface type and its options, voice and fax settings,
and voice communications for the region of the world that the MultiFRAD resides in. The Channel
Setup dialog box is accessed from the Main MultiFRAD menu. The Channel Setup dialog boxes
contain three tabs that partition the channels into three categories, i.e., interface, voice/fax, and
regional.
Interface
The interface tab defines the parameters related to the physical interface of the voice/fax channel.
Depending on the interface type selected (FXS, FXO, or E&M), other options on the interface tab will
turn grey (become inactive) indicating that they do not apply to the selected interface. Max Dial
Digits, Inter Digit Time and Autocall features apply to all interface types.
The Max Dial Digits indicates the maximum number of digits the MultiFRAD will allow you to enter in
the Phone Directory Database. This value is the number of digits, not an actual phone number. As
soon as you have entered this number of digits, the MultiFRAD searches the database for a DLCI
that matches the phone number. The range for the Max Dial Digits is from zero to 16 digits with a
default of five.
The Inter Digit Time (in milliseconds) option in the Dialing Options group defines the amount of time
the MultiFRAD waits between digits before searching the Phone Directory Database. The range for
this option is 200 to 10,000 with a default of 2,000.
The Auto Call option allows the local MultiFRAD to call a remote MultiFRAD without the user having
to dial a Phone Directory Database number. As soon as you access the local MultiFRAD voice/fax
channel, the MultiFRAD immediately connects to the remote MultiFRAD that you identified in the
Remote MultiFRAD Phone Number field of this option.

FXS Interface

The FXS Interface is used to connect telephones, fax machines, key telephone systems, etc., to the
MultiFRAD. In addition, you need to select either Loop Start or Ground Start. Most of the equipment
mentioned will use Loop Start which is the default.
