The 1−port Fast Ethernet plus channelized T1/PRI network modules offer a single, integrated 10/100 BaseT
port with one− or two−port T1/PRI interfaces. These T1/PRI interfaces are available with and without an
integrated CSU. The network modules without an integrated CSU have a DB−15 connector and require a
connection to an external CSU, PBX, or, channel bank, whereas the network modules with an integrated CSU
connect directly to the Telco network via an RJ−45 cable.

Each of the T1 network modules support speeds up to 1.544 Mbps full−duplex, provide up to twenty−four
virtual interfaces in channelized mode, and up to twenty−three ISDN B−channels in PRI mode.
