WAN overview
You can use an MM340 E1/T1 media module or an MM342 USP media module as an endpoint
for a WAN line on both the G250 and the G350. You can also use the Fast Ethernet port on the
G250/G350 chassis as the endpoint for a WAN line by configuring the Fast Ethernet interface
for PPP over Ethernet (PPPoE). The G250/G350 serves as a router, as well as the endpoint, for
the WAN line. For more information about routing, see
The G250/G350 supports the following WAN features:
PPP over channeled and fractional E1/T1 — the G250/G350 has the ability to map several
