WPIM-T1 Provides a T1 interface through a front-panel RJ45 port
and includes a built-in CSU/DSU for direct connection to
a T1 line. The WPIM-T1 provides both Full T1 or
Fractional T1 using 56 or 64 Kbps Time Slots, with a total
throughput of up to 1.544 Mbps. Time Division
Multiplexing (TDM) allows for channelization of up to 24
links over a single physical T1/FT1 interface. CSX201
WPIM-T1/DDS This WPIM provides both a T1 and DDS interface that
allows you to easily switch between the two interfaces by
changing the physical cabling and reconÞguring the
desired interface with either QuickSET or SPMA.
Currently, however, SPMA does not support a DDS
interface on a CSX device.
For more information on these WPIMs, consult the appropriate hardware
documentation or your QuickSET documentation.
