1.3 Functional Description

MT1000A contains the following printed circuit boards:

• One main circuit board that includes four tributary interfaces

• One or two fiber optic interface boards (A and B)

• One or two power supplies (A and B): AC/48 VDC wide-range power supply

Fiber Optic Link

Fiber Optic Link Interface Characteristics

The fiber optic interface can be used to provide a secure link in hazardous or hostile environments, increase the maximum connection range, and achieve immunity against electrical interference and protection against the harmful effects of ground loops.

The fiber optic interface complies with the requirements of ITU-T Rec. G.956, and uses a proprietary signaling format that ensures optimum performance. To optimally meet a wide range of system requirements, the fiber optic interface can be ordered for operation over 62.5/125 micron multi-mode fibers (typical attenuation 3.5 dB/km at 850 nm), as well as over low-loss 9/125-micron singlemode fibers (typical attenuation 0.4 dB/km at 1310 nm, and 0.25 dB/km at 1550 nm). Most of the options can be ordered with ST, SC, or FC/PC connectors. In addition, 9/125-micron single mode over a single fiber is also available (with SC connectors only).

Not

The SF3 option uses an SC/APC connector. The FO cable connected to it must therefore be of the same type.

Table 1-1 provides information on the characteristics of the optical sub-system,

including the maximum range over typical fiber optic cable. The maximum range values given in the table assume a 3 dB margin.

All the fiber optic interface options offer high performance and have a wide dynamic range, which ensures that the receiver does not saturate even when using short fiber optic cables (saturation is caused when the optical power applied to the receiver exceeds its maximum allowed input power, and results in very high bit error rates).

Fiber Optic Link Redundancy Option

MT1000A can be ordered with one or two link interface options. Each interface operates independently, and can be ordered from any of the link options listed above.

In the fiber optic link redundancy option, MT1000A supports fully automatic switching between link A and link B. Link A has priority. Therefore, normally link A is selected for use, and link B is disabled. In case a failure occurs on link A, MT1000A automatically switches to link B and continues providing normal service. After link A returns to normal operation, it is automatically reselected.

Each link interface has its own set of indicators that show the current state of the link. AIS alarm will not appear for the non-active optical link.

Tributary Interface Characteristics

The MT1000A tributary interfaces meet the requirements of ITU-T Rec. G.703. Each tributary port has a 100Ω balanced line interface terminated in an RJ-45 eight-pin connector.

1-4 Functional Description

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.

Each tributary interface has its own set of indicators that show the current state of the tributary link. The user can disable the alarm indications generated by unused interfaces (via internal switch and terminal, see section 2.5). AIS data streams are transmitted instead of failed or unconnected tributary data streams.

Test and Diagnostics Capabilities

MT1000A has comprehensive test and diagnostics capabilities that include local and remote loopbacks on the fiber optic link interface and on each tributary link. The activation is performed by sending a special test sequence through the fiber optic link. An automatic self-test on power-up further enhances maintenance.

For more information on activating loopbacks see Chapter 4.

Alarms and Alarm Indications

MT1000A can detect the following alarm conditions on each T1 and fiber optic interface:

• Loss of input signal

• Loss of frame synchronization

• Reception of alarm indication (AIS) signal, which consists of a continuous

sequence of 1s.

Notes

• When AIS is received, loss of frame synchronization occurs. However, in this case the alarm indicating the loss of frame synchronization is suppressed.

• AIS alarm will not appear for the non-active optical link.

When not all the tributaries are in use, the user can disable the alarm indications related to the unused tributaries.

The response to alarm conditions is as follows:

• AIS is transmitted on each tributary output in the following cases:

 Loss of fiber optic input signal is detected

 AIS is received on the fiber optic input

 Loss of fiber optic frame synchronization.

• For each tributary, an AIS signal is sent instead of the tributary data stream

through the fiber optic link in the following cases:

 Loss of tributary input signal is detected

 AIS is received on the tributary input

 Loss of tributary frame synchronization.

Functional Description 1-5

Chapter 1 Introduction MT1000A Installation and Operation Manual

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.

• Loss of tributary input signals, or loss of frame synchronization

• Unable to activate redundancy.

The minor alarm is activated in the following cases:

• Reception of AIS signal on the fiber optic input.

• Reception of AIS signal on tributary inputs.

Management and Monitoring

MT1000A units are equipped with a front panel serial RS-232 management port and an Ethernet management port. The RS-232 port operates at user-selectable rates of 9.6, 19.2, 38.4, 57.6 and 115.2 kbps over a null-modem cable. The Ethernet port operates at a rate of 10 Mbps and can be set to full- or half-duplex.

The management interface supports the following management methods:

• Supervision Terminal–An ASCII terminal connected to the RS-232 port (or a

PC running a terminal emulation program) can be used as a supervision terminal. All software required for the various management functions available through the terminal is contained in the MT1000A.

• SNMP Management–The management interface includes an SNMP agent that

enables SNMP management of the MT1000A, using the UDP-over-SLIP (Serial Link Internet Protocol) protocol. The SNMP agent also enables management by other SNMP-based systems.

• Ethernet Management–A management terminal can be connected to the

MT1000A via an Ethernet connection, using a UTP-CAT5 cable. The 10BaseT Ethernet interface supports a throughput of 10 Mbps. All software required for the various management functions available through the terminal is contained in the MT1000A.

Power Requirements

MT1000A can be ordered with one or two power supplies. Two types of power supplies are available:

• AC/DC wide-range for operation on AC (100 to 240 VAC) or on

DC (40-72 VDC) sources

• DC operation on 24 VDC source.

Each power supply (A and B) can be ordered as one of the above power supply types).

1-6 Functional Description

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.

5.4 Diagnostic Tests

MT1000A supports the following types of loopback connections:

• Loopbacks toward the local MT1000A

• Loopbacks toward the remote MT1000A.

The test functions are controlled by the management software. During all loopbacks, the TST indicator lights up on the units that participate in the loopback path.

The available loopback functions are described in the following paragraphs.

5-4 Diagnostic Tests

MT1000A Installation and Operation Manual Chapter 5 Testing and Diagnostics

Local Loopbacks in the MT1000A

You can set two types of local loopback connections in the MT1000A unit:

• T1 local, which is set for each T1 interface separately from a terminal.

• Fiber optic link local, which can be set from a terminal.

T1 Local Loopback in the MT1000A

The T1 local loopback returns the T1 transmit signal to the output of the receive path. Simultaneously, an unframed all-ones signal is sent to the MUX. Figure 5-1 shows the T1 local loopback connection.

This test checks the operation of the connections to the equipment attached to the local tributary interfaces.

Diagnostic Tests 5-5

Figure 5-1 T1 Local Loopback in the MT1000A

Chapter 5 Testing and Diagnostics MT1000A Installation and Operation Manual

Fiber Optic Link Local Loopback in the MT1000A

The fiber optic local loopback returns the transmit signal of the active fiber optic link interface to the input of the receive path. Simultaneously, the local MT1000A sends an unframed all-ones signal to the fiber optic link. Figure 5-2 shows the fiber optic link local loopback connection.

When this loopback is activated, the equipment connected to the local MT1000A tributary must receive its own transmission.

This test checks the operation of the local MT1000A, and the connections to the equipment attached to the tributary interfaces.

MT1000A Installation and Operation Manual Chapter 5 Testing and Diagnostics

Remote Loopbacks in the MT1000A

You can set two types of remote loopback connections in the MT1000A unit:

• T1 remote, which is set for each T1 interface separately, from the terminal.

• Fiber optic link remote, which can be set from the terminal.

T1 Remote Loopback in the MT1000A

The T1 remote loopback returns the transmitted Demuxed T1 to the receiver Mux. Simultaneously, the MT1000A sends an unframed all-ones signal to the T1 link.

Figure 5-3 shows the T1 remote loopback connection.

This test checks the operation of the local MT1000A and the connection to the remote MT1000A unit.

Chapter 5 Testing and Diagnostics MT1000A Installation and Operation Manual

Fiber Optic Remote Loopback in the MT1000A

The fiber optic remote loopback returns the received signal of the active fiber optic link interface to the input of the transmit path. Simultaneously, the remote MT1000A sends an unframed all-ones signal to the input of the Demux.

Figure 5-4 shows the fiber optic remote loopback connection.

This test checks the operation of the local MT1000A and the connection to the remote MT1000A.

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.

Connect the wires of your power supply cable to the TB plug, according to the voltage polarity and assembly instructions provided below.

Caution: Prepare all connections to the TB plug before inserting it into the unit’s VDC-IN connector.

Preparing and Connecting the Power Supply Cable with the TB Plug

Refer to Figure 2 for assistance.

1. Strip the insulation of your power supply wires according to the dimensions shown.

2. Place each wire lead into the appropriate TB plug terminal according to the voltage polarity mapping shown in Figure 4. (If a terminal is not already open, loosen its screw). Afterwards, tighten close the three terminal screws.

3. Pull a nylon cable tie (supplied) around the power supply cable to secure it firmly to the TB plug grip, passing the tie through the holes on the grip.

4. Isolate the exposed terminal screws/wire leads using a plastic sleeve or insulating tape, to prevent the possibility of short-circuit.

5. Connect the assembled power supply cable to the unit by inserting the TB plug into the unit’s VDC-IN connector until it snaps into place.

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.

Warning:

• Reversing the wire voltage polarity can cause damage to the unit!

• Always connect a ground (earth) wire to the TB plug’s Chassis (frame) Ground terminal. Connecting the unit without a protective ground, or interruption of the grounding (for example, by using an extension power cord without a grounding conductor) can cause harm to the unit or to the equipment connected to it!
