Chapter 1. Introduction 1.4 E1 Signal Structure E1 link line rate The E1 line operates at a nominal rate of 2.048Mbps. E1 link line coding The basic E1 line signal is coded using either the Alternate Mark Inversion (AMI) or HDB3 rule. In the AMI format, "ones" are alternately transmitted as positive and negative pulses, whereas "zeros" are transmitted as a zero voltage level. AMI is not used in most 2.048Mbps transmissions because synchronization loss occurs during long strings of data zeros.
Chapter 1. Introduction The 4-CHANNEL T1 Port Card supports two T1 line codes: AMI coding. B8ZS coding. The 4-CHANNEL T1 Port Card supports only transparent unframed format. 1.6 Applications / Capabilities In the following example, the MULTIPLEXER UNIT utilizes an optical fiber connection between a pair of units to provide 4, 8, 12 or 16 channels of E1, T1, Datacom, or 1 to 4 channels of Ethernet Bridge between the units.

Chapter 2. Port Card Overview Duplex: The original specifications for Ethernet did not allow any bi-directional transmissions. The Ethernet operated in a half duplex mode. Modern Ethernet has the ability to operate in Full duplex mode which essentially doubles the throughput from 10Mbps to 20Mbps on 10Base-T or from 100Mbps to 200Mbps on 100Base-TX. Using this setting requires connection to equipment which also supports Full duplex Ethernet. Setting DIP-4 OFF will enable this Full duplex mode.
Chapter 3. Installation 3.1 General This chapter explains in detail the requirements and procedures for the installation of the MULTIPLEXER UNIT Standalone/Rack Mount Fiber Optical Multiplexer. 3.2 Site Preparation Install the MULTIPLEXER UNIT within reach of an easily accessible grounded AC outlet. The outlet should be capable of furnishing 90 to 250 VAC (20 to 60 VDC for DC supply). Allow at least 10cm (4 inch) clearance at the rear and front of the MULTIPLEXER UNIT for signal lines and interface cables.
Chapter 3. Installation 3.4 Electrical Installation 3-4-1. Power connection For a model with AC power supply, AC power (90~250VAC) is supplied to the MULTIPLEXER UNIT through a standard IEC 3-prong receptacle, located on the rear of the chassis. For a model with DC power supply, DC –48V (20~60VDC) is connected to the terminal block, observing the proper polarity. In the AC/DC model, both IEC receptacle and DC terminal block are provided for dual power operation.

Chapter 6. SNMP Operation 6.1 General 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. Network management allows you to monitor and control network devices remotely using conventional computer network technology.
Chapter 6. SNMP Operation 6.3 The Management Information Base The management information base (MIB) includes a collection of managed objects. Managed objects are defined as parameters that can be managed, such as specific information on device configuring or on performance statistics values. 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.
Chapter 6. SNMP Operation 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(4756) Enterprise-specific MIB's are published and distributed by their creators, who are responsible for their contents. Specific information regarding the CTC Union's sub-tree are available from CTC Union's Research and Development Division. The MIB supported by the MULTIPLEXER UNIT SNMP Agent follows RFC 1158 (MIB-II standard). 6.
