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.
