Line Build Out
Determines the pulse shape and transmit power levels used on the
analog output of the Digital Line interface. The dB settings are for long
haul configurations and the distance settings for short haul
configurations. Always use the short haul settings since Allworx
equipment is intended for use with a local smart jack only and not for
driving the physical T1 lines on the telephone poles directly. Select the
length setting that matches the cabled distance between the Allworx
server and the service provider’s demarcation point. If this setting is
improperly configured line errors may be very common or problematic
and affect system reliability.
PRI Switch Type
Select the Primary ISDN (PRI) switch type that is in use by the service
provider. Select NONE if there is no connection of this interface to a PRI
based service.
Note:If this parameter is improperly configured the telephone service will
most likely work, however there will be subtle problems when certain
type of conditions occur such as calling cell phones, busy numbers, or
during network congestion. Additionally, this may affect Caller ID
functionality as well. Take care to find out the correct setting from the
service provider and set this parameter accordingly.
Voice Channel Selection Order
Determines the order the Allworx PBX attempts to seize a line for
outgoing calls within each service group assigned to this Digital Line.
Set this selection to be the opposite direction that the service provider
uses for incoming calls. For example, if the service provider hunts
incoming calls starting from slot 1 towards higher numbered slots
looking for the first available channel for a new incoming call, configure
the PBX for Descending Mode. If the service provider starts at the top
and hunts toward lower-numbered slots, select Ascending Mode. This
parameter is not critical but having it properly set dramatically lowers the
probability for a condition called glare where both the PBX and the
Central Office attempt to put the same slot into service simultaneously
for two unrelated calls.
Caller ID Name
Since most PRI lines hook directly into the international SS7 telephone
signaling network, it is possible to have parties see any Caller-ID string.
For analog phone lines, the CO determines this string but for PRI lines,
the Allworx server can determine it. Set the caller ID name field to the
preferred value for called parties to see when placing outgoing calls on
this Digital Line.
Note:The service provider may override these settings.
