    ESU LT - E1 CSU/DSUs with a single Nx56K/64K serial port. • ESU 120e - Same as the ESU LT with the added feature of a G.703 drop port and a slot in the rear panel to house an option module. Each module offers up to four additional data ports.

  • Page 18: Esu Lt Features

    Chapter 1. Introduction The ESU 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 user-programmable. The data terminal equipment (DTE) data can occupy contiguous or alternate channels in the E1 stream, and the channels may start at any position.

  • Page 19: Esu Lt Configuration Application

    Chapter 1. Introduction ESU LT CONFIGURATION APPLICATION The following example illustrates a possible ESU LT application. Bridge/Router Application A bridge or router can be interfaced to the network by using the DTE interface. The bandwidth used is programmable at Nx56 or Nx64 data rates for E1 or FE1 service.
