I have four Adtran 550's (one at each site) with a T1 Connection providing data only communications to each location.
I am interested in replacinf these devices with newer less exspensive alternatives.
Question 1: Would a Cisco 1720 provide a simple soltution for terminating a T1 to Ethernet 100 Mps.
Question 2: If this would not be an option, what Cisco box would provide the needed termination/routing?
Question 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?
Thank you in advance for your assistance!!!!

It depends on the topology of how your sites are interconnected to each
other. Please describe in greater detail.

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.

Gmail has the 128-SSL Connection so it cannot be viewed on all phones. If you really want to access Gmail on your mobile download ProfiMail from LonelyCatGames and configure setting for Gmail (GOOGLE THE SETTINGS) in ProfiMail. ProfiMail is like a Outlook Express but for a mobile phone.
A T1 line is a dedicated connection to an Internet backbone router. Typically a T1 line is for major businesses and school campuses. A T1 line is capable of handling 637 simultaneous VOIP connections with full-duplex connection.
How many computers do you intend to have connected to this network? Even a fractal T1 is very expensive. A full T1 connection can cost nearly 25K per month usage. A T1 line will need to be installed by your ISP provider and this too will cost a significant amount of money and it depends on how close your network connection will be in relation to the main network trunk-line.
If you trying to connect a T1 line to a Belkin 54g wireless router, you are way out of your league. I have worked for several networking firms in the Atlanta, GA area and we never had more than a fractal T1. Most small to midsized networks (up to 100) users can be accommodated with using a DSL or Cable Internet connection with a dedicated firewall and router/switch to handle the network traffic. Unless you are willing to pay for a T1 fiber optic line to be run from the main trunk line to your place of business or home, you will be fine with a high speed cable internet connection from an ISP provider like Comcast of Qwest here in the US. Fiber still has an installation cost of about $10,000USD per 1000 feet.
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 :-)
