TSU LT 220V OVERVIEW

The TSU LT 220V belongs to the ADTRAN T1 single-port CSU/DSU family and offers complete

flexibility in connecting various data sources to T1 or FT1 facilities (see Table 1-1).

The TSU LT 220V 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.
