Step 6: Install the Coupled Bonding Conductor
Installation of the G350 Media Gateway 51
December 2003
Connecting an external router to the G350
You can connect a router to any of the following ports on the G350:
• the ETH WAN port on the G350 front panel.
• the ETH LAN port on the G350 front panel.
• the Gigabit Ethernet port on an MM314 media module.
• one of the 24 10/100 Ethernet ports on an MM314 media module.
Step 6: Install the Coupled Bonding Conductor
The Coupled Bonding Conductor (CBC) provides mutual inductance coupling between the CBC and the
telephone cables that are exposed to lightning. The conductor can be a 10 AWG (4 mm
2
) wire tie wrapped
to the exposed cables, a metal cable shield around the exposed cables, or six spare pairs from the exposed
cable. In a high-rise building, connect the CBC to an approved building ground on each floor.
Before you begin, be sure the telephone lines are cross-connected to the appropriate media module(s).
To install the CBC
1 Connect one end of the conductor to a telephone cable building entrance protector ground that is
connected to an approved ground.
2 Route the rest of the conductor next to the exposed telephone cables being protected until they
reach the cross-connect nearest to the telephone system.
3 Terminate the other end to the single-point ground block provided for the telephone system.
NOTE:
Position the non-exposed telephone cables at least 12 in. (30.5 cm) away from exposed
telephone cables whenever possible.
