Chapter 1. Introduction 1.4 E1 Signal Structure E1 link line rate The E1 line operates at a nominal rate of 2.048Mb/s. 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 2.048Mb/s transmissions because synchronization loss occurs during long strings of data zeros.
Chapter 1. Introduction 1.6 Applications / Capabilities In the following example, the Fiber Multiplexer 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. The timing scheme for typical E1 or T1 equipment is to transparently pass timing from a timing source unit on one side, to a timing slaved unit on the other.
Chapter 1. Introduction This page left blank intentionally. 10 Version 1.
Chapter 2. Port Card Overview 2.1 Introduction This chapter provides a more descriptive over-view of the available 4-Channel Port card options. Detailed specifications are in Chapter 1, while removal and replacement procedures are detailed in Chapter 3. Unit configuration is all covered in Chapter 4. The cards are NOT designed to be "hot" swappable, therefore make sure the Fiber Multiplexer chassis is powered off before replacing a card or pulling it from the chassis.
Chapter 2. Port Card Overview 2.6 4 x Data I/F Module Overview The 4 x Data 4-Channel Port Cards for the Fiber Multiplexer are modular PCAs which slide into the Fiber Multiplexer chassis and provide four completely independent Data (V.35, X.21, RS-530, RS-449, or RS-232) interfaces. The PCA module terminates with a HD62F connector that is designed to connect to a physical adapter. The Data module is available in one of ten interface and cable options. 1. 4 x V.35 with 4 MB34 Female connectors 2. 4 x V.
Chapter 2.

Chapter 2. Port Card Overview When the Fiber Multiplexer is ordered with an RS232 Port Card option, a 4-CHANNEL RS-232 Card and adapter cable are supplied with each DB25 wired according to the following table.
Chapter 2. Port Card Overview 2.7 Ethernet Bridge Module Option When the Fiber Multiplexer is ordered with an ET100 Port Card option, a Single-Channel Bridge Port Card is supplied. Complete bridging functions are provided. BRIDGE FEATURES 10BASE-T/100BASE-TX, Full Duplex or Half Duplex HP Auto-MDIX, detects and corrects crossed cables IEEE 802.
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 DIP1-4 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 Fiber Multiplexer Standalone/Rack Mount Fiber Optical Multiplexer. 3.2 Site Preparation Install the Fiber Multiplexer 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).
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 Fiber Multiplexer 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 3. Installation 3.4.2 Rear and Front panel connectors All 4-Channel Port Cards install into the rear of the Fiber Multiplexer. The back plane provides both DC power to the 4-CHANNEL Port interface cards and routes signals from the cards to the multiplexing circuitry. From here, the multiplexed signal is sent to the Fiber Interface modules installed in the front panel. Mains Switches external clock IEC AC Mains Input Datacom (V.
Chapter 3. Installation 3.5 Removal/Replacement Procedures 3.5.1 Optical Module Removal / Replacement (Hot Swappable) The optical interfaces are installed into the front of the Fiber Multiplexer. The front plane connectors of the internal mainboard provide both DC power to the optical interface cards and routes signals from the cards to the multiplexing/de-multiplexing circuitry.
Chapter 3. Installation 3.5.2 Channel Port I/F Module Removal / Replacement ****CAUTION**** All the following removal/replacement procedures must be done with all power sources disconnected. All 4-Channel Port Cards install into the rear of the Fiber Multiplexer. The channel connector for E1/T1 is held by two "thumb" screws. Loosen both thumb screws (use a flat blade screwdriver if they are too tight), then remove the connector adapter by gently pulling straight back.
Chapter 3. Installation 3.5.3 Top cover Removal / Replacement for internal access Normally, there is no need to remove the cover of the unit. All interface cards can be removed and replaced without the need to access the internal portion of the Fiber Multiplexer. However, to change any AC or DC power module, add the SNMP and/or External clock feature, or to change the internal firmware, internal access is required and the cover must be removed.
Chapter 3. Installation 3.5.4 External Clock Feature Removal / Replacement ***CAUTION*** This procedure should only be performed by qualified service personnel. In addition, all power connections must be removed before attempting to open the case. 1. If the unit is installed in a rack, it must be removed. 2. Follow the procedure in 3-5-3 to remove the top cover. 3. Remove the two screws on the cover plate for the external clock feature. Once the feature is installed, this cover is no longer needed. 4.

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 Enterprise-specific MIB's are published and distributed by their creators, who are responsible for their contents. The MIB supported by the Fiber Multiplexer SNMP Agent follows RFC 1158 (MIB-II standard). 6.5 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.
