hello there, i am a newbie with cisco routers. i was able to connect to 2 buildings using 1600 on the one end and a 1700 series router on the other end thru a copper lease line. i just found a cisco 878 router in the market and it has a g.shdsl wan port, can i use it on both ends? what would be the requirements? is the copper lease line enough? thank you so much in advance.

Sure, copper dry pair lease will let you connect the two g.shdsl routers just fine. Remember one side has to provide clock.
Hope this helps, if so please rate post!

Nothing to be sorry. Look at this doc for configuration;

sir, this doc really helps me a lot. straight forward config. thank you so much. i have just wandering one thing on my setup from computer at building two i can ping the ip of the ethernet and atm of the two routers also the LAN at building b.... but from a computer from building b, i cannot ping the ip of the atm0, but I can see the LAN. I think it's weird. What would be the thing that i miss in the configuration.? here is the config. thanks

Hi,
do you feel ready for a little bit of dynamic routing?
on both routers:
router rip
version 2
network
redistribute static
At that point if you do "show ip route" on the other building router you should see "0.0.0.0 via

When dynamic routing is in place,you just need to leave the static default route 0.0.0.0.
There is also a setting so that it is learnt automatically from PPP, but it not so important to do so.

guys, i was able to have the existing configuration work, problem is i forgot to make a static route to the internal LAN. it is now working. with regards to the dynamic routing, i've tried it on my other setup and it works fine. thank you so much for being patience with me.

Sure can do Voip, connect you equipment and if there are quality issues search CCO "LLQ QoS" and try to apply a configuration example.

Hi,
You got this working I see and I'm trying to do exactly the same thing. Could you possibly post a working config of both the CO & CPE routers please ?
Regards,
Stuart
