CSX WPIMs 2-5
Device Configuration
service provides users with dedicated, two-way
simultaneous transmission capabilities operating at
transfer rates up to 64 Kbps. This WPIM comes with a
built-in CSX/DSU. (CSX203)
WPIM-DI The DI (Drop-and-Insert) WPIM 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-
DI provides Full T1 or Fractional T1 using 56 or 64 Kbps
Time Slots. It also provides a second Drop-and-Insert
interface that allows more than one device, such as a
PBX, to share a single T1 connection. (CSX201)
WPIM-E1 This WPIM provides an E1 interface through a front-
panel RJ-45 port and includes a built-in CSU/DSU for
direct connection to an E1 line. This WPIM provides Full
E1 or Fractional E1 using 56 or 64 Kbps Time Slots with a
total throughput of up to 2 Mbps. Time Division
Multiplexing (TDM) allows for the channelization of up
to 31 links of a single physical interface. (CSX201)
WPIM-HDSL This WPIM is designed for campus environments and
provides a connection for sending LAN trafÞc over
existing telephone lines at rates up to 1.544Mbps. It can
communicate reliably up to a distance of 12,000 feet over
Unshielded Twisted Pair (UTP) cabling.
WPIM-S/T For the CSX400 only . This WPIM provides an ISDN 128
Kbps Basic Rate Interface (BRI) and is designed for an
ISDN back-up link for a frame relay or leased line. In the
United States and Canada, Network Terminator
equipment (NT1) is required to provide an interface
between the WPIM-S/T and the ISDN line.
WPIM-SY Provides a synchronous serial connection of up to 2.048
Mbps to external communications equipment (an
external CSU/DSU is required). For the CSX202. The
following electrical interfaces are supported. An external
CSU/DSU is required (consult your hardware
