		Channelized Data
Overview
What Is It?
	The Channelized Data option provides an alternative to using Serial Data Boards
	(SDB) to concentrate data traffic from remote nodes attached to the PathBuilder
	S24x, 26x, and 27x switch through a multiplexer.
	Using one T1 or E1 card installed in a PathBuilder S24x, 26x, and 27x switch,
	Channelized Data supports a greater number of port connections between the
	PathBuilder S24x, 26x, and 27x switch and remote nodes than allowed is by SDBs.
	For example, eight SDB cards installed in the PathBuilder S24x, 26x, and 27x switch
	plus three motherboard ports allow a maximum of 19 connections per node, or two
	ports per SDB card. With Channelized Data you can make up to 30 connections
	using a T1 card or E1 card.
		Note
		Each E1 or T1 card contains two ports. However, the Channelized Data option
		only supports up to 30 configured virtual ports for data traffic. The remaining
		virtual ports available on the PathBuilder S24x, 26x, and 27x switch are reserved
		for uncompressed voice traffic.
	The Channelized Data option is configurable from the Control Terminal Port. See the
	“Configuring Channelized Data” section on page 5-3for details on how to configure
	a PathBuilder S200 series switch for channelized data operation.
Statistics and
	The Channelized Data option uses the standard X.25 and Frame Relay statistics
Alarms	available for the PathBuilder S200 series switch products family. Refer to the X.25
	Configuration Basics Guide for information on statistics.
	For details on alarms and reports, refer to the Alarms and Reports manual.
Software
	No Software Authorization Key is required to enable Channelized Data on a

Authorization Key PathBuilder S24x, 26x, and 27x switch.
