Toll Restriction; Tone On Hold - Comdial DXP Plus Manual

DXP Plus General Description

Toll Restriction

With the toll restriction feature, the system allows or denies outgoing line calls to selected users over
selected lines. Toll restriction meets different dialing needs by allowing users to dial numbers that they
are required to dial yet restrict them from dialing numbers they are not allowed to dial. Toll restriction can
be used together with the automatic route selection and call costing features if desired, or used separately
as a stand alone feature or not used at all.
The programmer assigns toll restriction to stations based on system requirements. Telephones that are not
assigned this feature are free to dial any number their users choose to dial. Plus, a toll restricted station
can dial any telephone number that it is not restricted from dialing. If a station is restricted from dialing a
certain telephone number on a certain line, it can, if programming permits, dial that number on another
line that is not restricted. Further programming action specifies whether or not toll restriction applies to
system speed dial numbers. The programmer can also differentiate between day toll restrictions and toll
restrictions that only take effect in night mode. A defaulted system imposes no toll restriction on any
station.
The toll restriction feature first compares a dialed number to a matching assigned restricted number up to
the last digit in the assigned number. At that point it considers it a match and applies other toll restriction
tests whether the station user keeps dialing or not. If all toll restriction tests are met, the station is not
normally allowed to dial the number. There are 32 exception number test matches assigned to the station.
Exception numbers allow stations to dial numbers that they are not normally allowed to dial by their toll
restriction.
Toll Restriction Pause Entries
When this feature is activated by installers, they can enter a pause at the end of a restricted number's digit
string to indicate that dialing is complete. They do this by typing a P or p after they type the digit string.
The pause entry distinguishes this restricted number as unique. They can enter the same digits without the
pause but instead followed by additional digits as another unique number. They can assign different
routing and toll restriction parameters to each of these entries. There are several applications for this
feature. One application is in international dialing where different toll restriction parameters apply
depending upon whether the caller dialed 0 or 011. In this case, installers can enter 0 pause to access local
lines and 01 to access international lines. Another application is with tie line calling where a remote
extension is the same digits as an office or area code that installers need to enter in the restriction table.
By entering nnn pause for tie line access and nnn@ for CO line access, the system can route the call over
the proper line. A third application is brought forth with the advent of the new North American
Numbering Plan (NANP). With NANP, an area code may be the same digits as a local office code.
Installers can enter nnn@@@@ pause for local line access and nnn@@@@@@@ for long distance line
access (the @ is a match anything character). In any application, the system resets its pause timer after
receiving each caller dialed digit. If the timer expires before the caller dials another digit, the system
routes the call based on the digits preceding the pause. If, instead, the system detects more digits instead
of a pause, it routes the call based on the entire digit string.

Tone On Hold

This feature gives you an alternative to providing music or no music for callers who are placed on hold.
When you program this feature into the DXP Plus system, both internal and external callers hear a pattern
of short tone bursts while they are on hold. The patterns consist of two 1/10-second tone bursts separated
by 1/10-second. These tone patterns repeat every five seconds.
The installer enables this feature and assigns it to particular trunks through line programming or stations
through class of service programming using the PC. The system manager can also select this feature from
the applicable class of service from a programming station for intercom calls placed on hold. The choices
when programming this feature are: music from source one, music from source 2, tone on hold, or nothing.
