CSX200 and CSX400 WAN Configuration

	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.
