    BERT testing. The operator at either end of the line may test both the ETU-01A and the line in the remote digital loop back mode. The loop back is controlled by local LCD display setting, serial console, optional SNMP or by the DTE interface for V.35, RS-232 and RS-530.
  • Page 13 The ETU-01A E1 link receive path always operates on the receive clock. The ETU-01A recovers the receive clock from the received E1 link data signal. The source of the ETU-01A E1 link transmit clock may be selected by the user. The following E1 link transmit timing modes are available: •...
  • Page 14 • External (DTE) timing: The ETU-01A has three data channel clocking modes: • Clock mode DTE1: The ETU-01A data channel accepts the user transmit clock from the connected DTE (from the ETC pin) and provides a receive clock (Transparent timing) to the synchronous equipment connected to the data channel.

  • Page 15: Typical System Application

    Chapter 1. Introduction 1.4 Typical System Applications General In a typical application (Figure 1-1), the ETU-01A is used in a point-to-point connection. The synchronous data channels of each host are connected over an E1 line. Figure 1-1 Point-to-Point Application Fractional E1 data service is based on the assumption that the user data rate is a fraction of the available E1 bandwidth, in multiples of 56K or 64K.

  • Page 16: E1 Signal Structure

    Chapter 1. Introduction 1.5 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 are a total of the 32 time slots, each containing eight bits, carrying the data payload.
  • Page 17 Chapter 1. Introduction Multi-Frame Alignment Signal (MFAS) MFAS framing uses Channel Associated Signaling (CAS) to transmit A/B/C/D bit signaling information for each of 30 channels. This method uses the 32 time slot frame format with time slot 0 for the FAS and time slot 16 for the Multi-Frame Alignment Signal and the Channel Associated Signaling.

As with all electronic devices that are powered from an AC line, dangerous voltages may be present inside the unit. The technician should exercise proper care and judgement. Only open the unit for service after disconnecting the unit from the power source.

    Chapter 6. SNMP Option 6.2 Simple Network Management Protocol 6.2.1 SNMP Overview The Simple Network Management Protocol (SNMP) is one of many protocols in the Internet Protocol (IP) suite. SNMP is the protocol recommended specifically for the exchange of management information between hosts residing on IP networks.
  • Page 113 Chapter 6. SNMP Option 6.2.2 SNMP Operations The SNMP protocol includes four types of operations: getRequest Command for retrieving specific value of an “instance” from the managed node. The managed node responds with a getResponse message. getNextRequest Command for retrieving sequentially specific management information from the managed node.
  • Page 114 Chapter 6. SNMP Option The MIB includes the definitions of relevant managed objects (MIB variables) for the specific node. Various MIB's can be defined for various management purposes, types of equipment, etc. The management data itself is a collection of integer, string and MIB address variables that contain all the information necessary to manage the node.
  • Page 115 The assigned number designates the top of an enterprise-specific sub-tree of non-standard MIB's. Within this context, CTC Union has been assigned the enterprise number 4756. Under this scheme, the path to CTC Union’s Enterprise branch would be: iso(1).org(3).dod(6).internet(1).private(4).enterprises(1).ctcu(...
  • Page 116 Chapter 6. SNMP Option 6.2.5 SNMP Communities To enable the delimitation of management domains, SNMP uses "communities". Each community is identified by a name, which is an alphanumeric string of up to 255 characters defined by the user. Any SNMP entity (this term includes both managed nodes and management stations) is assigned by its user a community name.
