Functional Description

The ADTRAN TSU is one of several T1 multiplexers that offers complete flexibility for connection of various data sources to T1 or FT1 facilities. This family of TSU multiplexers includes the following.

1.TSU - a T1 CSU/DSU with a single NX56k/64k serial port. See Figure 1-1, above and Figure 1-2 on page 1- 4.

2.TSU 100 - same as the TSU with the added feature of a slot in the rear panel to house an option module. Each module offers up to four additional data ports.

3.TSU 600 - same as the TSU with the added feature of six slots in the rear panel to house up to six option modules. Each module offers up to four additional data ports for a total of 24 possible data ports.

The TSU serves as the link between user data sources such as LAN bridges and routers, computers, CAD systems and teleconferencing equipment. The amount of bandwidth allocated to the port is custom programmable. The DTE data can occupy contiguous or alternate channels in the T1 stream, and the channels may start at any position.
