Connecting devices

Step 2: Install circuit protection

Out-of-building installations of telephones or other standard (tip/ring) devices/terminals that
connect to the Avaya G350 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 each of 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.
For the Avaya MM710 or MM340 T1/E1. Over-voltage and sneak current protection for the
●
Avaya MM710 and MM340 are provided on the Media Modules themselves
For the Avaya MM711, G350 TRUNK PORT 1 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:
With the exception of the MM712, all DCP media modules are intended for

in-building use only. Phone lines connected to these ports are not to be routed
out-of-building. Failure to comply with this could cause harm to personnel and
equipment.

Step 3: Connect to the Wide Area Network (WAN)

Since the G350 contains an internal router, you can connect the G350 directly to a WAN
endpoint device. You can also connect a WAN endpoint device to the G350 via an external
router.
