Circuit protection installation
Protection from over-voltages (lightning, power line induction and so forth) and over-currents (sneak
currents) is required for ALL off-premises (out-of-building) trunks, lines, and terminal installations.
Campus installations (interbuilding cabling) of telephones or other standard (tip / ring) devices
require over-voltage and sneak current protection in both buildings.
Over-voltage and sneak current protectors must be Listed devices, and installed in accordance with
NFPA 70: NEC Article 800 (subsections “Protective Devices” and “Cable and Primary Protector
Bonding and Grounding”), or must comply with local safety codes.
Field installed sneak current protectors must have a maximum current rating of 350mA and a
minimum voltage rating of 600V.
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
