atcomsystems.ca/forum Forums Wiring - Telecom Carriers - Trunks & Services T1's, CSU's and DSU's CSU/DSU Point to Point Question

I have a client that got a data only point to
point full T1 installed at two of their locations.
The vendor did not supply and CSU/DSU just the jacks and I was asked to make everything work.

I have asked for a parameter sheet on the
lines installed and was going to get two
ADTRAN NetVanta 3200 - Router - DSU/CSU

Is there anything else I should be aware of or
ask about? I l know I will have to configure
the Adtran accordingly ..

Thanks for your help.

You are on the right track, just need to configure the routers but its easy...

I agree. You could also use two Cisco 1721s with a WIC-1DSU in each. Point to point is easy to do if between two locations.

You either bridge the traffic between the sites (uh not the best way to go) or make sure that both sites have different private network IP ranges and default route out the WAN interface along with static routes for the opposing networks in each router.

Example:
Site 1: LAN Block 192.168.20.x/24
static route: ip route 192.168.30.0 255.255.255.0 serial0

Site 2: LAN Block 192.168.30.x/24
static route: ip route 192.168.20.0 255.255.255.0 serial0

Cisco routers and WICs are unnecessary as the Adtran NetVanta 3200s have already been chosen for that function.

Bridge, route or brout as necessary (the protocol and application will dictate that). Some very, very large companies still use some unroutable legacy protocols. Unlikely...but worth asking about.

Set both units for network timing. Check your own work at the first sign of trouble, but don't ever discount the degree that a telco (or their order taker) can screw things up. I once had a simple point-to-point that was designed with B8ZS/ESF one end and AMI/D4 on the other.

I agreed with the Adtran's but also gave the Cisco as an alternate.
