Prefabricated system cable 12 x RJ45
The cable is 6 m long and, at one extremity, has 12 RJ45 connectors for the inter-
faces on the front panel. Two of them have 4 cores; the others, 2 cores. This means
the cable is suitable for connecting the following interfaces:
• 2 network interfaces BRI-T or 2 terminal interfaces BRI-S or a combination thereof.
• 10 terminal interfaces (DSI, FXS) or a combination thereof.
Note:
This cable cannot be used to connect Ethernet interfaces (see also "Con-
nection of PRI primary rate interface", page 125 and "Connection of Ether-
net interfaces", page 166).
Tip
Use standard commercial connecting cables not just for the PRI and
Ethernet interfaces but also for connecting the BRI-T interfaces.
