Introduction
TSU LT OVERVIEW
The TSU LT belongs to the ADTRAN T1 single-port CSU/DSU family offering complete flexibility in
connecting various data sources to T1 or FT1 facilities (see Table 1-1).
The TSU LT serves as the link between user data sources such as local area network (LAN) bridges and
routers, computers, CAD systems, and teleconferencing equipment. The amount of bandwidth allocated to
the port is custom programmable. The data terminal equipment (DTE) data can occupy contiguous or
alternate channels in the T1 stream, and the channels may start at any position.
