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.
