SmartSwitch 1800 Voice Configuration
12-12 Configuring Voice Ports
Auto Dial Number
This parameter is only conÞgurable if Auto Dial (see above) is Enabled. It is a
number to which the SmartSwitch 1800 will attempt to connect when the handset
(or its equivalent) attached to this port is taken off-hook. The SmartSwitch will
automatically dial the long-form number deÞned in the Speed Dial ConÞguration
table that is associated with the speed dial number speciÞed here.
The number of digits you can enter is determined by the Dial Digits parameter
conÞgured in the Voice Parameters window (see ConÞguring System-Level
Voice Parameters, page 12-2).
Auto Poll
This parameter is only relevant if Auto Dial (see above) is Enabled. When Auto
Poll is enabled, the SmartSwitch 1800 polls the destination device with the
frequency speciÞed by Auto Poll Timer (see below). If the poll is not
acknowledged, the SmartSwitch will Òbusy outÓ the channel.
This parameter can be useful in situations where the destination is an emergency
number that must always be available. If the destination does not answer the
automatic poll, the busy-out condition will notify an attached PBX that the
emergency call should be routed to another call routing device.
The default value for this parameter is Disabled.
Auto Poll Timer
This parameter is only conÞgurable if Auto Poll (see above) is Enabled. It is the
frequency (in seconds) with which an Auto Poll will be sent. The default value for
this parameter is 10.
Speed
This speciÞes the speed of the port and is transmitted as part of a Call Setup
frame. A voice call will be established if there is enough bandwidth at each end to
provide the minimum conÞgured rate. The default value for this parameter is
8000 bps.
Interface
This parameter, in conjunction with the Telephony Type parameter (see below)
speciÞes the type of interface that will be used by the voice channel.
Telephony Interface Type Interface
OPX (FXO) Loop Start
SLT (FXS) Loop Start
EM 4W EM, 4W EM TE, 2W EM, 2W EM TE
AC 15 AC 15A or AC 15C
Loop Start and OPX operating modes provide characteristics similar to those of a
central ofÞce. Loop Start and SLT operating modes provide characteristics similar
to those of a standard telephone set.
EM is an interface used for PBX tie-trunk connections. When EM is speciÞed, the
SmartSwitch 1800 acts like the trunk side of a PBX.
