FACILITY DESCRIPTION
Faktaansvarig - Subject responsible
Capacity
The maximum number of trunks is determined by the
number of voice channels (60) .
32 different public numbers can be assigned to the
trunks. Up to 16 digits can be programmed per public
number.
Analogue trunk boards: maximum 7 boards (56 lines).
Digital 30B+D trunk boards: maximum 2 boards
(60 lines).
Digital 2B+D trunk boards: maximum 3 boards
(24 links=48 lines).
Limitations
When dimensioning the system ensure that the
number of trunks is in proportion with the number of
available voice channels and also to the relationship
between internal and external traffic.
In case of trunk to trunk connection and
using Line Signals (command 1201)
06 ( Australia, standard ) or
21 ( Standard with detection of disconnection tone )
the maximum time the caller is connected to the
desired party is 10 minutes.
Programming
Each trunk line can be programmed for adaptation to a
connected public exchange or other PBX.
NOTE Adaptation of transmission, line signalling
and system times requires excellent
knowledge of ASB 150 02 and the
relevant signal diagram.
On system level we define a table with up to 32
different public numbers ( command 2220 ) which will
be used in case of outgoing calls. One public number
per number group. In addition the type of the
programmed number has to be specified ( national,
subscriber, .... ). Which number type has to be sent out
depends on the public network. With the information
on the individual trunk about the dedicated trunk
number group it is possible to find the corresponding
public number in the table. Finally the opposite parties
directory number will be added.
2220
Public directory numbers
Up to 32 public directory numbers can be
programmed.
In addition the number type has to be specified.
Type of number:
- Subscriber The prog. digits contain the public
subscriber number.
- National The prog. digits contain the public
destination code and the
subscriber number.
- International The prog.digits contain the country
code, public destination code and
subscriber number.
- Unknown Only direct indialling digits are
programmed.
- Network specific The content of the digits
programmed depends on the
respective network operator.
The descriptions of commands provided below are
brief and state a handling program for the
programming of trunk lines.
Recommended programming sequence for trunk line
data:
- Program one route at a time.
- Program one line in the route and copy its data
to the other lines in the route
- Repeat the procedure for the other routes.
5605-5607 Number series:
Via these commands it is possible to alter the number
series for individual line positions or for all trunk lines.
5605
Assign directory number to the line position
5606
Change directory number for individual trunk line
