For the longest time, Cisco didn't support OPX lines. We had a few OPX stations which were built, with a circuit from our MDF to the central office, and back out to the location.
PBXs could handle this _no_ problem. Finally, they released OPX Lite. An example: http://www.cisco.com/c/en/us/products/collateral/unified-communications/vg224-voice-gateway/prod_qas09186a00801d87b5.pdf Q. What distance can the VG300 Series OPX-Lite ports drive? 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. So only 2 to 3 miles. :( Sent from my iPhone > On Jun 22, 2016, at 3:50 PM, Louis Koekemoer (ZA) > <[email protected]> wrote: > > > > Hi all, > > What would be the maximum length one will be able to run an analogue > extension or what device can one use to extend the length? > > Regards > > Louis > > > > Sent from my Samsung device > > > This email and all contents are subject to the following disclaimer: > "http://www.dimensiondata.com/emaildisclaimer"; > _______________________________________________ > cisco-voip mailing list > [email protected] > https://puck.nether.net/mailman/listinfo/cisco-voip
