They are great, but correct network design is essential.

The IRX-111 has 1 async 115200 serial port and 1 synchronous 2048k
v.35/RS232 port
The IRX-112 has 1 async 115200 serial port, 1 synchronous 2048k v.35/RS232
port, and 1 synchronous 128k v.35/RS232 port
The IRX-114 has 1 async 115200 serial port, 2 synchronous 2048k v.35/RS232
ports, and 2 synchronous 128k v.35/RS232 ports

Yuck! You really need to see what options your telco offers. You also need
to analyze what type of traffic and what quantity will travel from office
to office. From your description, it sounds like frame relay would be your
best bet. This does depend on your overall network plan, but from your
description, I think this would work best. An added benefit is that you
only need one t1 csu/dsu router combo at your main site and each remote site.
