Step 2: Connect to the Wide Area Network (WAN)

Since the G250 contains an internal router, you can connect the G250 directly to a WAN
endpoint device. You can also connect a WAN endpoint device to the G250 via an external
router.

Connecting a WAN to the G250

There are some differences in how to connect the WAN, depending on the type of WAN link you
are connecting. This section provides separate instructions for connecting various types of
WAN links, as follows:

●
Connecting an E1/T1 WAN link

Connecting a USP WAN link
You must connect the USP WAN link to a device connected to the Avaya MM342 media
module. To connect the WAN link, plug the WAN line into the USP port on the MM342 media
module. This port is marked USP. To connect the WAN line to the port, use one of the following
cable types, depending on the service provider's equipment:
