[Lelio Fulgenzi]

Another option is an Ethernet extender or xDSL modem pair that will give you a low speed network connection. Should be enough for an IP phone.

> A. The VG350 supports two modules: SM-D-72FXS and SM-D-48FXS-E. The first 4 ports (ports 0 through 3) on the SM-D-72FXS module can be configured for long loop-length (OPX-Lite), and all 48 ports on the SM-D- 48FXS-E support OPX-Lite. On the VG310, the first 8 ports (0 through 7) can be configured for OPX-Lite. On the VG320, the first 4 ports (0 through 3) can be configured for OPX-Lite. For all the VG300 Series models, the OPX-Lite ports can drive up to 11,000 feet using 26 AWG wire, and up to 18,000 feet using using 24 AWG wire.
