FACILITY DESCRIPTION
Faktaansvarig - Subject responsible
Digital link parameters
The following commands are valid for all configured
ISDN system connections.
2060
Consolidation time from alarm to OK
The system continuously monitors the existing ISDN
connections. In case that one ISDN connection fails for
undefined reasons, an internal alarm will be raised.
Command 2060 states for how long the ISDN
connection has to work correctly again in order to
cancel the alarm condition.
Valid data: 0 - 255 sec
2061-2065
First to fith priority link to be master for synchroni-
sation
Commands 2061-2065 state which digital interface
(board position / individual link ) shall be used first for
synchronisation and which others shall be used if the
first one fails. If a synchronisation source is defined,
and connected to a co-operating exchange,
ASB150 02 acts as "slave" and always takes over the
clock of the "master". This synchronisation strategy is
designed for 5 different sources. If no BTU-D/BTU-B_/
MFU is stated for synchronisation, the internal system
clock will be the master. This is used in case of a tie
line configuration.
In a tie line configuration one PBX has to be always
configured as "master" and the other one as "slave".
If the system is connected to the public network, it
always acts as a slave and takes over the clock from
the public network.
Number analysis
In this command group the exchange's national
significant number will be defined to be used for the
supplementary service CLIP and COLP.
(Depending on the configuration of the following
commands ASB 150 02, sends out either the complete
national significant number, the subscriber number or
only the directory number of the called or calling
extension).
According to the CCITT numberplan E.164 the
national significant number comprises the national
destination code and the subscriber number.
The subscriber number comprises the public access
number + directory number of the connected or calling
extension.
ASB 150 02 creates the national significant number by
connecting the defined digits from command 2220 +
directory number of the connected or calling extension.
2220
Public directory numbers
This command sets the public directory numbers for
the 32 public number groups. The numbers are used in
applications for which the public number and/or the
length of the public number must be known.
The number is also used in applications for which the
internal extension numbers in the public network must
be known. The extension numbers will then be built by
taking the corresponding public number from the table
(see command 1030 Public Number Group) and
adding the internal directory number to the
programmed number.
