The TXPORT PRISM 3111/3112 CSU/DSU terminates a broad range of T1/FT1
networking applications. The single port 3111 and the dual port 3112 models
integrate voice and data, LAN-to-LAN networking, or disaster recovery in either
managed or unmanaged environments.
It provides the T1 network connection through an advanced integral ESF CSU.
Full performance T1 span monitoring allows early detection and correction of
problems before they affect critical applications. The unit provides a wide range of
test functions and loopbacks to aid in rapid fault isolation and repair and also

equipment connections.
The PRISM 3111/3112 is compatible with industry standards ensuring access to
any T1 provided service and allowing connection of all equipment quickly and
correctly. The unit uses Flash memory allowing firmware upgrades in the field
