SmartSwitch 1800 Voice Configuration
12-10 Configuring Voice Ports
SLT Timeout
This is the time (in seconds) the local voice port will wait before an actual fax
transmission begins. If there is no fax tone when this timer expires, the connection
will be terminated. The default value for this parameter is 30.
Jitter
This Þeld speciÞes the amount of jitter delay (in 5-millisecond increments), which
is used to compensate for the variable arrival time of frames. Inconsistent arrival
can result in a choppy voice quality. Increasing the jitter buffer size will increase
the end-to-end delay, but will insure smoother voice quality.
Sample Delay
This Þeld speciÞes the amount of sample delay.
Level In
This speciÞes the local voice level into the voice port. This parameter adjusts the
sensitivity of the local voice channel to the signal from the attached device. The
purpose of this parameter is to match the voice channel dB level to the input
signal. A more negative setting produces a higher input gain (i.e., 7 produces the
least input gain and -22 produces the highest input gain). If the In level is reduced
(made more negative), the voice channel will be more sensitive to the input; this
will cause the voice output at the remote device to sound louder.
The default value for this parameter is 0.
Level Out
This parameter speciÞes the local voice level out of the voice port. A more positive
setting produces a higher volume (i.e., 7 produces the highest volume, -22 the
lowest). The default value for this parameter is -4.
Long Dial Prefix
This parameter speciÞes a character or number that will be required preceding
calls using the long-call format (i.e., when a speed-dial number is not used). When
the user at an attached device (e.g., telephone or fax machine) dials a long-form
number, the number must be preceded by the Long Dial PreÞx. Valid values are
the digits 0-9 and the characters * (asterisk) and # (pound sign). The default value
for this parameter is * (asterisk).
Num Digits Delete
This speciÞes the number of leading dial digits that will be deleted before a dial
string is forwarded. This parameter is primarily used to delete leading digits that
may be inserted by an attached PBX. For example, assume the user of attached
equipment dials 1234 and the attached PBX inserts the number 9 as a preÞx to the
dial string. If Num Digits Delete is set to 1, the SmartSwitch 1800 will remove the
9 before forwarding the dialed digits 1234. The default value for this parameter
is 0.
