Dear All, Thanks for your help, ideas, suggestions, etc.
We use the same setup at the moment (with 3/2 down/up) but I was wondering if we could increase the length of the V.35 link so we can move the router to our computer room from the earth station for ease of maintenance, etc.We are using SDM-300 Sat modems with a UB-530 interface board. This has an EI-530 interface which can be wired to V.35 standards. We have our core routers at the SES (only < .5 mtr away) and using Ethernet take it to the distribution/access network where one is 500mtrs and another is 2km. We keep the internet traffic on a separate VLAN to distribute it. This way you need not have to run it into a Mux or converter... Saves you money.
I look through the blackbox site and they had converters, extenders, etc but with max of 2mbps.
Our link is presently configured to work at 3M down and 1M up. I know that V.35 can go up to 5Mbps after that we will shift to HSSI or Ethernet interface on the sat modems.

Before the modem was connected via coax to a DXC (convert from coax to v.35) and then to the router in our computer room. The problem with the DXC is that its limited to 2mbps link. I am wondering how we can extend our connection so that we can move our router back to our computer room for easier maintenance, etc.Short of upgrading your DXC to support speeds above 2Mbps, the only other options would be to have a small router used as "media" convertor at the earth-station (V.35 one side, ethernet the other), connecting to your main router back at the office by ethernet (up to 100 metres) or by fibre. What speed are you trying to support? Or get some device that will extend >2Mbps circuit over fibre... I started browsing through RAD's website, and maybe something like http://www.rad-direct.com/Application-t3-extender-fiber.htm could work. This particular one won't as it only supports T3s. Sorry, I don't have much idea otherwise... :-( Upgrading the DXC seems easiest if you can't leave the router at the earth-station. philip -- _______________________________________________ pacnog mailing list pacnog at pacnog dot org http://mailman.apnic.net/mailman/listinfo/pacnog
