Chapter 1. Introduction
4 TSU 600 User Manual 61200.076L2-1
The TSU 600 serves as the link between user data
sources such as local area network (LAN) bridges and
routers, computers, CAD systems, teleconferencing
equipment, and PBXs. Through the use of multiple
data ports, the TSU 600 can simultaneously connect
one or more of these devices to a T1 circuit. The
amount of bandwidth allocated to each port is custom
programmable. The bandwidth allocation can be
changed manually or set to automatically change at
predetermined times to use the available bandwidth
most advantageously. Changes in the configuration
are accomplished without disrupting data flow in
channels that are not being reconfigured. The unique
architecture and the availability of the option modules
provides a path for growth to accommodate future
requirements.
