Chapter 1 Introduction 1.1 Overview General MT1000A is a second-order multiplexer that combines four T1 (1.544 Mbps) tributary data streams into a single fiber optic link. The fiber optic interface provides a secure link in hazardous or hostile environments, increases the maximum connection range, and achieves immunity against electrical interference and protection against the harmful effects of ground loops.

MT1000A Installation and Operation Manual Chapter 1 Introduction Line coding is B8ZS or AMI. The nominal balanced interface transmit level is ±3.0 V. The line attenuation is up to 12 dB, and each T1 signal is processed by an adaptive equalizer that compensates for various cable lengths to ensure optimal performance. Phase Locked Loops (PLL) are used to recover the clock signals, and the resulting jitter performance complies with the requirements of ITU-T Rec. G.824.
MT1000A Installation and Operation Manual Chapter 1 Introduction Front panel indicators display each alarm condition. In addition, a dedicated connector is used to provide major and minor alarm indications, by means of dry contacts. The major alarm is activated in the following cases: • MT1000A is not powered, or total power supply failure (e.g., when two power supplies are installed, failure of both supplies). • Loss of fiber optic input signals, or loss of fiber optic frame synchronization.
MT1000A Installation and Operation Manual Chapter 1 Introduction When two power supplies are installed, they share the load; in case one of the supplies fails or its input power is disconnected, the other power supply continues providing power to MT1000A. 1.4 Technical Specifications Fiber Optic Interface Characteristics Applicable Standards ITU-T Rec.

Mechanical and electrical installation procedures for MT1000A are provided in the following sections. After installing the unit, refer to Chapter 3 for operating instructions and system configuration procedures.
Chapter 2 Installation and Setup MT1000A Installation and Operation Manual Fiber Optic Link Connections Each fiber optic link interface is terminated in two ST, SC, or FC-PC connectors, in accordance with order. The maximum allowable attenuation depends on the interface option ordered (refer to Table 1-1). When working with the WDM option, only one fiber optic cable per link should be connected.
MT1000A Installation and Operation Manual 2.5 Chapter 2 Installation and Setup Installation and Setup To install MT1000A: 1. Set the internal switches. 2. Connect MT1000A’s various interfaces in the order listed here. Warning This module may include Class A or Class 1 lasers. For your safety: • Do not look directly into the optical connectors while the module is operating. Remember that the MT1000A starts operating as soon as it is powered. • Do not attempt to adjust the laser drive current.

DC Power Supply Connection – Terminal Block Connector Note: Ignore this supplement if the unit is AC-powered. Certain DC-powered units are equipped with a plastic 3-pin VDC-IN power input connector, located on the unit rear panel. Different variations of the connector are shown in Figure 1. All are functionally identical. Supplied with such units is a kit including a mating Terminal Block (TB) type connector plug for attaching to your power supply cable.
Note: Certain TB plugs are equipped with captive screws for securing the assembled cable’s TB plug to the unit’s VDC-IN connector (C and E types only). To secure the plug, tighten the two screws on the plug into the corresponding holes on the sides of the input connector as shown in Figure 3. Captive screws Figure 3. TB Plug with Captive Screws (optional) DC Power Supply Wire Voltage Polarity Refer to Figure 4 for proper mapping of the power supply wire leads to the TB plug’s three terminals.
