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.
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.
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.

FRONT PANEL OVERVIEW The ESU LT front panel monitors operation and controls the configuration of the unit. Figure 3-1 shows the ESU LT front panel. Table 3-1 describes each part of the front panel. Front panel operation is more fully described in subsequent pages.
Item Name Description LED ON when ESU LT has clear to send (CTS) active toward DTE. A 2X16 LCD window that displays menu items used in configuration and displays information useful in monitoring the unit. It also displays alarm and status information.
Chapter 3. Operation Config (Configuration) The C menu displays and sets the ESU LT ONFIGURATION operational configuration, including all network interface parameters, the allocation of the TS0s, and the port parameters. For detailed information on configuration options, see Configuration Menu on page 41.

T-Watch PRO Management Software Program T-Watch PRO is the ADTRAN management software program that allows the user to control the ESU LT from a PC. It provides complete control over the configuration of the ESU LT using a graphic interface. The T-Watch PRO program displays the same status and performance data as the front panel LCD.

FAS word is located in timeslot 0 of even frames. Odd numbered frames may contain the Not FAS word (NFAS) in timeslot 0. The ESU LT can be configured to require the NFAS word for frame sync. In CCS mode, there are 31 channels (timeslots 1-32) available for user data.
Selects the clock source for transmission toward the network from the NI. Choices: N ; DTE ETWORK NTERNAL The clocking option selected always designates the clock source for transmission. Clocking necessary for receiving data is always re- covered from incoming data. ESU LT User Manual 61200410L1-1B...
Figure 5-3. Network Timed Clock Source Internal Timing The ESU LT is the source of timing. The ESU LT is configured to use its own internal oscillator as the source of timing. Applications include private line driver circuits where one end is set to network and the other to internal.
Chapter 5. Configuration Menu DTE Timing The DTE is the source of timing. The ESU LT uses the incoming DTE clock to determine the transmission timing. This is typically used in applications such as limited distance line drivers, where it is necessary to have the DTE as the primary clock source.
Sets baud rate for communications with PC or modem. Position Determines whether this ESU LT is at the head of a chain of units (directly connected to the modem or PC). The head of the chain is referred to as the master unit. Units down the chain are referred to as slaves or a slave unit.
Chapter 5. Configuration Menu Output Selects whether the alarm traps (if enabled) are sent directly, or whether the telephone number stored in the ESU LT should be dialed first (industry-standard AT dial command sent to modem). Choices: D IRECT Tel Num This is the telephone number which is dialed to obtain alarm traps.

Chapter 7. Test Menu QRSS ACT TS0s The ESU LT has an internal QRSS pattern generator and detector. The pattern only appears in the TS0s assigned to the Nx56K/64K port. The QRSS test pattern can be used in conjunction with network loopbacks to perform end-to-end tests.
Chapter 7. Test Menu This menu function is very useful for testing end-to-end integrity of the network. First loop up the far end ESU LT. Then send a 511 pattern from the local ESU LT. The ERRORS screen can then be used to determine if the link is functioning properly by verifying that no errors are being counted.
Port Tests are used to control the activation of a DTE loopback. This test loops data received at the high-speed serial interface back towards the DTE. See Figure 7-7. Figure 7-7. Loopback Setting Screen Cancel Tests Use to deactivate all active tests. 61200410L1-1B ESU LT User Manual...
