Install Circuit Protection

Over-voltage and sneak fuse protection measures are necessary for the safe operation of the G700 Media
Gateway system.

Over-Voltage and Sneak-Current Protection

Out-of-building installations of telephones or other standard (tip/ring) devices/terminals that connect
to the Avaya G700 Media Gateway Media Modules require over-voltage and sneak current protection
at both building entry points. Sneak current protectors must have a maximum of 350 mA and a
minimum voltage rating of 600V. The following devices have been evaluated or tested and approved
to protect the Media Modules from over-voltages and sneak current protection:
• Avaya MM712 DCP: either 146E IROB (In-Range Out-of-Building) or 4C3S-75 solid state
protectors for surge and sneak current.
• Avaya MM710 T1/E1: over-voltage and sneak protection for the Avaya MM710 T1/E1 Media
Module is provided on the Media Module itself.
• Avaya MM711 Analog: analog trunks use the 507B or 110-SCP-9 sneak current protectors. Over-
voltage protection is normally provided by the local telephone company. Analog voice terminals
use one of the following types of combined over-voltage and sneak current protection:
- Gas tube with heat coil: 4B1E-W
- Solid state with heat coil: 4C1S
- IROB: 146C (4-lines) or 146F (25-lines)
!
WARNING:
Only service-trained personnel are to install these circuit protection devices.
