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 mm2) 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
1Connect one end of the conductor to a telephone cable building entrance protector ground that is
connected to an approved ground.
2Route the rest of the conductor next to the exposed telephone cables being protected until they
reach the cross-connect nearest to the telephone system.
3Terminate 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.
