CSX200 and CSX400 WAN Configuration
3-4 CSX WPIMs
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
documentation for cable pinout information):
EIA-RS449
V.35
EIA-RS232D
X.21
EIA-RS530
EIA-530A
RS530 ALT A
RS530A ALT A
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 QuickSET or SPEL. Currently,
however, SPECTRUM Element Manager does not
support a DDS interface on a CSX device.
