  • Page 10: Signal Structure

    Chapter 1. Introduction 1.3 E1 signal structure The E1 line operates at a nominal rate of 2.048Mbps. The data transferred over the E1 line is organized into frames, with each E1 frame containing 256 bits. The 256 bits consist of 32 time slots of eight bits each, which carry the data payload. E1 transmission utilizes two main types of framing: Frame Alignment Signal (FAS) and Multi-Frame Alignment Signal (MFAS).

  • Page 11: Etu01-Plus Capabilities

    External timing: The ETU01-Plus E1 link transmit clock is locked to the clock signal provided by the user DCE connected to the data channel. When the data channel is used as the clock source, the data channel must use clock timing mode 3 (DTE2) or 4 (DTE3).
  • Page 12 The ETU01-Plus can select from one of five clocking mode settings. Clock mode 0 (DCE 1): The ETU01-Plus data channel operates as a DCE and provides both transmit and receive clocks (recovered timing) to the data terminal equipment connected to the user channel.
  • Page 13 E1 transmit link. Clock mode 3 (DTE 2): The ETU01-Plus data channel is physically wired as DCE. However, the ETU01- Plus may operate as a DTE when connected to other DCE equipment by using a cross-over data cable and by setting the clock mode to the DTE2 setting. NOTE: The X.21 data channel cannot be operated in clock timing mode 3 (DTE2).

    E1 transmit link. 1.6 Functional Description The ETU01-Plus is a single port access unit for E1 or Fractional E1 service. The ETU01U-Plus is a single port access unit for Unframed E1 only. The ETU01-Plus AC model has a universal, auto-switching power supply (90~250VAC) while the DC model's internal regulator module accepts DC voltages from 18 to 75 volts.

  • Page 15: Loopback Feature

    The operator at either end of the line may test both the ETU01-Plus and the line in the digital loop back mode. The loop back is controlled by either a manual switch or by the V.35 DTE interface.
  • Page 16 In the previous application, the ETU01-Plus is connected over hardwire point to point. The ETU01-Plus can also be connected to an E1 network or to E1's provided by SDH equipment. Within the SDH network, the E1 can be cross mapped at the VC12 level to provide point to point connections.

  • Page 17: Chapter 2. Installation

    Install the ETU01-Plus within reach of an easily accessible grounded AC outlet. DC power capable units connect via terminal block connection. Allow at least 10 cm (4 inch) clearance at the rear of the ETU01-Plus for signal lines and interface cables. 2.3 Mechanical Assembly The ETU01-Plus is designed for tabletop or bench installation, and is delivered completely assembled.

  • Page 18: Dip Switches

    RRING (Receive data in) Cable and Termination Use a shielded twisted pair cable between the ETU01-Plus and the DTE device. The receivers on the ETU01-Plus are 100 Ohm terminated. If problems are encountered with the connection to the V.35 DTE interface, make sure that the DTE interface is terminated correctly.

  • Page 21: Chapter 3. Operation

    This chapter describes the ETU01-Plus controls and indicators, explains operating procedures, and supplies instructions for settings. Installation procedures (in Chapter 2) must be completed and checked before attempting to operate the ETU01-Plus. 3.2 Controls and Indicators All controls (push-button switches) and LED indicators are located on the ETU01- Plus front panel.
  • Page 22 Control Switch Function Loc dig loopbk The local digital loop back switch causes the local ETU01-Plus to loop E1 received data to its transmitter. Loc ana loopbk The local analog loop back switch causes the local ETU01-Plus to loop transmitter output back to its receiver.

    2. Diagnostic loops are required. 3.3.1 Visual Indicators The ETU01-Plus is turned on when its AC power cord (or central office DC power) is connected to an AC power outlet (or the DC input connections) and the power switch is turned to the ON position. Initially, all LEDs will light, followed by all LEDs flashing rapidly 5 times.

    Internal Oscillator timing Based on the above point to point application, use the following DIP switch graphic to visually set the ETU01-Plus units. This example will use CCS (PCM31) framing with CRC4 and provide 1024kbps (16 timeslots) throughput. ON=Enabled Pushbuttons...

  • Page 25: Chapter 4. Test & Diagnostics

    The loop back test buttons (Loc dig loopbk, Loc ana loopbk and Rem loopbk) and the LED indicators built into the ETU01-Plus allow for rapid checking of the data terminal, ETU01-Plus and the E1 line. Before testing the operation of the data system equipment and their line circuits, ensure that all units are turned on and are configured correctly.

  • Page 26: Local Analog Loop Back

    4.5 Local Digital Loop Back This test is activated by depressing the "Loc dig loopbk" button. The test consists of looping the received data back to the remote ETU01-Plus. This test checks the performance of the local ETU01-Plus, the remote ETU01-Plus and the connections between them (see Figure 4.3).

  • Page 27: Remote Digital Loop Back

    4.6 Remote Digital Loop Back This test is activated by depressing the "Rem loopbk" push button. The test determines the performance both of the local and the remote ETU01-Plus units, as well as their interconnecting lines. The remote digital loop back test consists of providing a loop back at the remote ETU01-Plus (see Figure 4.4).
