4.1.2 Programming
z
Group membership
-
A station may be member of several groups.
By default all stations are member of Group 1. Group 1 defines all
stations that shall receive emergency PA announcements.
Note! Analogue telephones will receive the PA announcement only if
they are in a conversation.
z
Group Access Level
-
Used to specify which group and PA calls a user may perform.
Each group used for group and PA calls will have an associated
‘Group
Access Level’
. The levels are:
low (=0), medium(=1) and high(=2)
.
The user must have a higher or the same group access level.
By default the group used for emergency PA announcement is
programmed as
group 1
with group access level
high
. Only users with
group access level
high
can make an emergency PA announcement.
z
Class of Service (COS)
-
Determines which system features the station can activate.
There are 16 different classes available and each can be freely programmed.
A station (analogue telephone) can only have one defined COS.
An ACM solution is usually programmed with the following available
Classes of Service:
-
COS 1
Regular stations in the system
-
COS 2
Notify busy station
-
COS 3
Override of absent or private feature
-
COS 4
Busy override
-
COS 5
Override of busy, absent and private
-
COS 16
Includes all services. Default for SuperUser
4.1.3 Terminal
connections
z
LCM
-
The LCM module number.
ACM-M-A-V2 has only one module. Large exchanges (ACM-48, ACM-
144) may have more than 60 subscribers and need for two or more
modules.
z
Station terminal number
The A,B,C and D wires are the 4 wires used towards stations.
-
An intercom station uses all 4 wires.
-
Analogue telephones use 2 wires, either the A/B or C/D wires.
z
RCO
-
These are programmable relay outputs linked to the associated
ACM physical numbers. (The first 6 on line board 1).
The RCOs are used to signal to external PA system and signal units.
4.1.4 Additionals
z
Information
Each station may have the following additional functions:
-
Members of a ringing group
. A ringing group is a group of
stations that will receive external calls in parallel. Calls to a ringing
group will have distinct ringing.
-
Parallel ringing.
Stations that are set up belonging to same
parallel ringing will ring in parallel. Up to 10 stations can be in
parallel ringing.
z
Ext field equipment
-
Field equipment is unit types that are installed in parallel on the line
to the telephone set, for instance an IRR-3 relay boxes.
