Module-specific data (continued)
Two isolating transformers ensure the necessary electrical separation from the peripherals.
All the instructions for programming digital or analog exchange lines also apply to the PRI module.
The code numbers correspond to the criteria for programming T
0
lines.
The management of the lines is dynamic. The assignment of a line number proceeds independently
of the B channel number. (I.e. line 4 can have the channel number 30 and line 30 the channel number 2).
In Germany the installation of an S
2
M connection is always combined with the allocation of 30 B channels.
As the use of all 30 B channels of the PRI module corresponds to the maximum extension of the system from
the exchange side, in this case no further T
0
connections or analog exchange line junctions are allowed to be
configured.
If nevertheless additional digital or analog exchange connection organs are configured, the useable number
of B channels is reduced accordingly.
The synchronization of the Integral
5 clock generator to the reference
pulse of the public network can be
done:
Using a T
0
interface (MSN or TK)
Using a S
2
M interface
In the case of an MSN connection, levels 1 and 2 of the T
0
interface are
deactivated if the T
0
line is not busy.
In the case of a TK connection, levels 1 and 2 are activated.
For an S
2
M interface, levels 1 and 2 remain activated. Consequently
the synchronization is prioritized principally on the S
2
M interface, since in the
case of the T0 line (MSN) the synchronisation clock is switched off at the end
of the connection.
If the PRI module fails or the S
2
M path is interrupted, the synchronization
takes place on an exchange plug-in module with T
0
interface that has access
to a T
0
line. If no T
0
line is available synchronization is internal. (as for T0 with
MSN in inactive state, when there is no call connection)
When the PRI module reports back again, the system ends the synchroni-
zation process on the T
0
interface and changes over to the S
2
M interface.
