My company had had a telephone installation job. This was pretty much an ordinary install. The company that was having the phone system installed was a long time customer who had purchased two systems from us. The one system that was installed in their old building was done so about 10 to 15 years ago. The other, in their new warehouse and office location, was installed about 3 to 4 years. It was time to replace the old system.
The phone techs that were on site were pretty good so when I got the call at about 9:30PM and saw who it was, I was surprised and curious as to what the problem could possible be. It turns out that on one side of the point-to-point T1 connection an Adtran Total Access 750, that I installed years ago, was removed and replaced with a Paradyne for the new phone system. They were able to configure the two systems through the paradyne to the point were the voice was working but the data, IP, wasn't working. The other side of the T1 was an Adtran TSU 600 unit which was unchanged - 8 channels voice and the rest of the DS0s were for data.
The voice was working but the data was not. He was on server on the new unchanged side and could not reach any computer desktop in the main and the same held true for the main side to the remote. I tried assisting them remotely by trying to talk them through the screens. I didn't have desktop remote access over the internet to configure the unit. Access to the paradyne was through the front panel only at this time I had to take a trip in.
What techs almost had it right, and they tried.
The Paradyne, when configured for voice and data needs:
- The port that connects to router must be set to V.35 (at least this is the most common configuration)
- If port 1 then that port must be assigned to NET in the configuration. The same applies if port 2
- Once the above is complete then additional options are available to configure the data channels.
- In the channel configuration under voice, the channels that are for data must be set to RBS - this one is the gocha.

I did an Adtran TSU 600 remotely a while back. I was able to connect to it over the internet. The tech support crew that was onsite setup access to it for me to connect from a remote office.
I has been a while since I have used Adtran total access products of this level. Mostly see routers and wireless routers. There was a time where my company used to install total access products and support them for clients. We also had purchased an Atlas product to simulate T1 lines a frame-relay links for testing and integrating communication systems.
