System Alarms
A DISA alarm will warn the customer if the DISA security system has been triggered by too
many incorrect password attempts. The alarm can ring any station or group of stations and
show an appropriate display at the assigned station(s).
System Maintenance Alarms
Internal system diagnostics are performed continuously while the system is operating. When
a major or minor fault is detected, the system can ring stations with an ALARM KEY assigned.
The keyset display shows information that includes the description, location and date and
time stamp for each alarm.
A log of 100 alarms is stored in a buffer and can be reviewed at a display keyset or sent to a
printer (see ‘Sample Alarm Report’ section of this manual).
System Directory
Each station, station group and outside line can have a directory name up to 11 characters.
This name will appear on keyset displays to provide additional information about lines and
stations.
Tenant Service
The Tenant Service feature allows the system installer to split the system between two
‘tenants’, each tenant being completely separate and having control over their own system
features such as operator groups, page zones,
speed dial numbers, DISA and customer-level
programming. No internal calling between tenants is permitted.
Toll Restriction
Any outside line may be programmed to follow station toll restriction or follow the toll
restriction class assigned to it. Each station and trunk can have a dialling class specified by
the time plan.
Allowance and Deny tables set in the system contain the numbers that can or cannot be
dialled. Each entry in a table is a maximum of 1
2
digits, and the maximum number of entries
per table is 500.
Each of these entries can apply to dialling classes B, C, D, E, F and G. Expensive calls, as
well as specific area and office codes, can be allowed or denied on a per-class basis. Class A
stations have no dialling restrictions and Class H stations cannot make outside calls.
Special Code Table
A Special Code Table of 10 entries (four digits each) allows use of telephone company features such
as CID Blocking or Call Waiting Disable without interference to toll restriction or LCR. The Special
Code table allows use of these custom calling features on a per-call basis.
Toll Restriction Override
Program options allow system speed dial numbers to follow or bypass a station’s toll
restriction class. In addition, users may make calls from a toll-restricted station by using the
Walking Class of Service or Authorisation Code feature.
