Adtran 1246026L4 I need to know what HTU C card is compatible

The Atlas 550 is modular, and can break out the 23 channels as BRI or FXS. Since you want 23 analog lines, I presume you want regular 2-wire phone lines (aka, FXS lines). The you that by using 3 "Octal FXS" modules (8 port modules) in addition to the T1 module.

You need to enter maintenance mode (a web interface) and check the power settings from there as some of these have the ability to sleep etc at preset times.

sort of added security and green all in one function

It sounds like you need to "crossover" the connection.

Using a crossover patch cable to connect the two devices is the first thing that comes to mind. (http://en.wikipedia.org/wiki/Ethernet_crossover_cable)

However, some routers/switches have physical buttons on ports to cross them over or you can use their web-based management to change port settings.

I hope this helps.

Here is a document which describes this.
Please download, it then:

1. Connect the console.
2. Configure ip address of the router
3. Enable telnet access.

It's not likely that VZ gave you dynamic IP's, but it's possible. You should have been given more than one. If not, it's better to get more and a set of configuration instructions. In the last one I set up, we put a 5-port switch on the ethernet port coming off the Adtran, then fed 2 routers and a security system from the switch. Our gateway was one number lower than the bank of IP's we had, and we just gave each piece of equipment a static ip address and gateway to the gateway :-)

try repalcing ethenet cable if that does not reslove issue either there is an accumulation of dust in the port or the port has gone bad.

1: Would a Cisco 1720 provide a simple soltution for terminating a T1 to Ethernet 100 Mps I recommend a 1721 2: If this would not be an option, what Cisco box would provide the needed termination/routing I recommend a 1721 3: If a Cisco device could do this would it be necessary to replace them at both locations or could it communicate with the Adtran device. It depends on the topology of how your sites are interconnected to each other. Please describe in greater detail.
