i am getting ready to install a ctx system with voip and wanted to know what would be the best router to use or could i use one of those small linksys jobs on my ip phone end cuz theres only gonna be 7 to 10 phones on it? i will be using a lipu card in my cabinet with a bctu1a proc. any help would be appreciated.

The last install I did was a 40 with the ip phones off site, so at the main office I ran the data off the adtran to a D LINK dumb switch. Into that went my IPU card and the office internet. Office internet had one STATIC IP ADDRESS and my IPU card had another. At the off site it doesn't matter what router you have, all the phones look for is that PUBLIC IP ADDRESS. Toshiba Tech support uses Sonic wall routers if that helps

Be careful. The Linksys wireless routers won't work. Particularly the WRT54G. Toshiba knows about this and will recommend alternatives.

Netgear WGT624 also have issues. What I have found is that Linksys WRT54G routers version 1-4 work fine. Version 5-8 do not. Linksys changed their OS and hardware. You can load DD-WRT firmware on versions 6-8 fairly easily and version 5 with a little more trying and then it will work. DD-WRT is open source linux/custom firmware. It is free as well.

Ok now heres the scenario thanx for the advice on the switches. what i am trying to accomplish is a point to point t1 connection between two locations what type of router would be best used on each end to run into the switch. i was given advice to use a cisco 1841 router is there any other alternatives that would be just as good but a little better priced? thanx again in advance.

For a point-to-point t1 connection you don't need a router. Just connect the two switches together like this.

switch - ethernet - csu/dsu - t1 - csu/dsu - ethernet - switch

Before you say I' crazy and don't know what I'm talking about, think about it. Why not make both sites into one big happy network?

grim reaper thats exactly what i want to accomplish. i want the remote end to use the data circuit of the main building for their internet access and just run the phones like they are part of the lan. so that way will work for me? do you recommend a certain csu dsu?

We have always used the Adtran TSU 120 for the above application.

Most CSU/DSU units have the V.35 or other high-speed serial port to connect to your network. You would then need a router or other media converter to connect this to your Ethernet LAN.

I did a little research online and found the Patton Model 2720/I CSU/DSU . This has an Ethernet connector in place of the high speed serial connector and can be plugged directly into your Ethernet switch at both ends. There is no router involved and these units pass the Bridge Packet Data Units (BPDUs) transparently across the T1 so that the Ethernet switches in both locations can talk to one another. In fact I believe all multicasts and broadcasts will pass across the T1 just like it was a local link.

One side would end up being the default gateway for all internet traffic from both sites, and Internet trafic from 1 site would be passing thru the P-T-P, right? I guess if the plan was to make 1 big network, then they would be in the same subnet, with the same default gateway.

Also, you could not get QOS without a router if you wanted to prioritize voice traffic, unless the switches supported QOS.
