Chapter 3 - Software Loading and Configuration
If your station device uses ground start, then chose FXS (Ground Start) option. Refer to the
device’s user documentation.
If you are using an extension from your PBX, then chose FXO option. Check with your in-
house telephone personnel to verify connection type.
If you are connecting to a trunk on your PBX, then chose E&M option.
If you chose an FXO interface, then the Dialing Options Regeneration group is enabled.
Check with your local in-house telephone personnel to verify whether your local PBX dial
signaling is Pulse or tone (DTMF). Set the Regeneration option accordingly.
For FXO-to-FXO communications, you can enable a specific type of FXO Disconnect -- either
current loss, tone detection, or silence detection. (Check with your in-house phone
personnel to verify the preferred type of disconnect to use.) For tone detection, you can
select from drop-down lists either one or two tones that will cause the line to be
disconnected; the person hanging up a call must then hit the key(s) that will produce those
tones. For silence detection, select One Way or Two Way, then set the timer for the
number of seconds of silence before disconnect. Note: the default value of 15 seconds may
be shorter than desired for your application.
If you choose the E&M interface, then the E&M Options group is enabled. Check with your
local in-house phone personnel to determine if the signaling is Dial Tone or Wink and if the
connection is 2-wire or 4-wire. If Wink signaling is used, then the Wink Timer is enabled
with a default of 250 milliseconds. The range of the Wink Timer is from 100 to 350
milliseconds. Consult with your local in-house phone personnel for this timer setting.
If you want to dedicate a local voice/fax channel to a remote voice/fax channel (so you will
not have to dial the remote channel), click the Auto Call Enable option in the Auto Call
group. Then enter the appropriate phone number in the Phone Number field.
Note: After configuring a given channel, you can copy that channel’s configuration to any
other channel by clicking the Copy button. Everything on the Interface tab will be copied to
the other channel.
14 Repeat the above step to configure the interface type for each voice/fax channel.
15 The Voice/Fax tab displays the parameters for the voice coder, faxing, DTMF gain, billing
charges for inbound and/or outbound calls, password authentication on inbound and/or
outbound calls, and auto disconnect which limits call duration.
16 To change the voice coder, first select the channel by clicking the Select Channel down
arrow and highlighting the channel number, then click the Voice Coder down arrow and
highlight your new voice coder entry.
If you changed the voice coder, ensure that the same voice coder is used on the voice/fax
channel you are calling; otherwise, you will always get a busy signal.
