Coupled Bonding Conductor Installations - Avaya G430 Deploying And Upgrading

Connecting devices
The following over-voltage and sneak current protection devices have been approved for use with
the G430 Gateway:
• For the Avaya MM710, MM710B media modules: Over-voltage and sneak current protection
for these interfaces are provided on the media modules themselves.
• For the Avaya MM711, MM714, MM714B, and MM716 Analog media modules: Over-voltage
and sneak current protection for these interfaces is provided on the media modules
themselves.
Note:
Incoming trunks normally have primary over-voltage protection provided by the local
telephone company.
Analog voice terminals require one of the following types of combined over-voltage and
sneak current protection at both building entry points:
- Gas tube with heat coil. 4B1E-W
- Solid state with heat coil. 4C1S
- IROB. 146C (4 - lines) or 146H (25 - lines)
• For the Avaya MM712 and MM717 DCP media modules: out-of-building connections require
either the 146E IROB (In-Range Out-of-Building) or 4C3S-75 solid state protectors for over-
voltage and sneak current.
• For the Avaya MM722 ISDN-BRI media modules: over-voltage and sneak current protection
are provided on the media modules themselves.
• For the Avaya MM720 and MM721 ISDN-BRI media modules: All out-of-building installations
(both trunk (network) side and line (customer) side) require either the 146E IROB (In-Range
Out-of-Building) or 4C3S-75 solid state protectors for over-voltage and sneak current. Trunk
(network) side applications also require an NT-1 device.
Warning:
Only service-trained personnel are to install these circuit protection devices.

Coupled Bonding Conductor installations

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
wire tie wrapped to the exposed cables, a metal cable shield around the exposed cables, or six
spare pairs from the exposed cable. Modem access is not supported if FIPS mode is enabled in
the gateway. In a high-rise building, connect the CBC to an approved building ground on each
floor.
