Primary rate interface PRI
With the interface cards TIC-1PRI, TIC-1PRI-T1
1)
and wiring adapters WA-1PRI, PRI
network interfaces can be made available at RJ45 sockets 1.1, 2.1, 3.1 and 4.1. For
test purposes the PRI interface is also routed in parallel to ports x.2. The possible RJ45
sockets are highlighted in colour in the figure below.

Connection possibilities for PRI network interfaces
Notes
– In normal operation the x.2 test socket must not be connected; otherwise faults may occur.
– Circuit type as per EN/IEC 60950: SELV
Cable Requirements
The connection to NT1 (Network Termination) is implemented using commercially
available screened cables with 8-pin RJ45 connectors at both ends, e.g. S-FTP 4P,
PVC, Cat. 5e.
