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).
Chapter 1. Introduction 1.4 ETU01-Plus Capabilities E1 link line coding The ETU01-Plus and ETU01U-Plus support two E1 line codes: AMI coding. HDB3 coding. E1 framing formats The ETU01-Plus supports three formats: Unframed format. FAS (CCS, PCM-31) format. MFAS (CAS, PCM-30) format. The ETU01U-Plus supports only unframed format. User data channel rates The ETU01-Plus supports user data channel rates which are a multiple of 56 or 64kbps. For maximum flexibility, the ETU01-Plus supports data rates up to 2.
Chapter 1. Introduction 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. The clocks are locked to the recovered E1 timing. Clock Mode 0: Recovery TC DTE Connected Equipt. RC DCE Data Port TX E1 E1 transceiver RX Figure 1.
Chapter 1. Introduction Clock mode 2 (DTE 1): In the transparent clocking mode, the ETU01-Plus data channel supplies the receive clock to the synchronous DCE, and accepts a transmit clock from the DCE (from the ETC pin). The DCE must transmit data at the rate of the clock signal supplied by the ETU01-Plus. Clock Mode 2: Transparent DCE Connected Equipt. ETC RC Crossover Cable TX DCE Data Port E1 E1 transceiver RX Figure 1.
Chapter 1. Introduction Clock mode 4 (DTE 3): The ETU01-Plus data channel is physically wired as DCE (classed as communication equipment). 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 DTE3 setting. The ETU01-Plus data channel then operates as a DTE and accepts both transmit clock and receive clock (both from the ETC pin) from the user equipment. Clock Mode 4: External DCE Connected Equipt.
Chapter 1. Introduction 1.7 Loopback Feature The ETU01-Plus features V.54 diagnostic capabilities for performing local loop back and remote digital loop back. 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. A front panel switch generates an internal 511 bit pseudo random test pattern, according to ITU-T, for direct end-to-end integrity testing.
Chapter 1. Introduction 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. Figure 1.7 E1 Point-to-Point over SDH Application In these cases the E1 timing will be set to "Recovery" to synchronize to the SDH network's timing.
Chapter 2. Installation Chapter 2. Installation 2.1 General This chapter provides detailed instructions for mechanical installation of the ETU01-Plus. Following the completion of installation, please refer to Chapter 3 for operating information. 2.2 Site Preparation Install the ETU01-Plus within reach of an easily accessible grounded AC outlet. DC power capable units connect via terminal block connection.
Chapter 2. Installation E1 Line BNC coax connector Two BNC coax connectors marked TX and RX. RJ-45 Connector The pin assignments for the RJ-45 connector are as follows: Pin: Function: 4 TTIP (Transmit data out) 5 TRING (Transmit data out) 1 RTIP (Receive data in) 2 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.

Chapter 3. Operation Chapter 3. Operation 3.1 General 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 ETU01Plus front panel. Depress a push-button to activate (turn ON) the corresponding control.
Chapter 3. Operation Table 3.1 Control Functions Control Switch Function Item 1 Loc dig loopbk 2 Loc ana loopbk 3 Rem loopbk 4 Pattern Item Indicator The local digital loop back switch causes the local ETU01-Plus to loop E1 received data to its transmitter. The local analog loop back switch causes the local ETU01-Plus to loop transmitter output back to its receiver. The transmitter sends 'all ones' data to the line.
Chapter 3. Operation 3.3 Operating Procedure The ETU01-Plus requires no operator attention once installed, except for occasional monitoring of the front panel indicators. Intervention is only required when: 1. The ETU01-Plus has to be adapted to new operational requirements. 2. Diagnostic loops are required. 3.3.

Chapter 4. Test & Diagnostics Chapter 4. Test & Diagnostics 4.1 General This chapter contains procedures for performing system diagnostic tests. 4.2 Loop Back Tests 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.
Chapter 4. Test & Diagnostics 4.4 Local Analog Loop Back This test is activated by depressing the "Loc ana loopbk" button. This test checks the performance of the ETU01-Plus, the local data terminal and the connections between them. It is performed separately at the local and the remote sites (see Figure 4.2): Loc ana loopbk Depressed E1 CLK XMTR DATA DATA TERMINAL CLK RCVR DATA X ETU01-Plus ETU-01 Figure 4.2 Local analog loop back 4.
Chapter 4. Test & Diagnostics 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). A system test may be performed by first depressing the remote loop back switch, then depressing the pattern switch.
