FOCUS System Manual Future Capabilities — FOCUS is designed with the future in mind. The use of position-independent channel slots permits adding or modifying features as required in the future. 1.7 Transceivers The T1/E1 link interfaces between terminals may be either optical or electrical. Once the communications medium for a particular link is known, the appropriate transceiver can be selected. Some examples of links include fiber optics, microwave, or other digital transmission paths.
Chapter 1. Product Description 1.9 Framer Module The Framer Module has four interfaces for bidirectional links in the east, west, north, and south directions. These correspond to transceiver 1-1, 12, 2-1, and 2-2, respectively. This provides communications along an T1/E1 line to the network. All data and control information is communicated by 2048 kbit/s serial streams conforming to Mitel’s ST-BUS format. The ST-BUS is a TDM serial bus.
FOCUS System Manual 1.12.1 Ring Down The ring down capability provides a point-topoint communications circuit using a standard telephone set at each end of the circuit. This capability is achieved by use of a standard telephone set and the originating Two-Wire Module (V2W). The V2W carries the signal over a single DS0 in a FOCUS system. The call may be initiated from either end by lifting the handset of the telephone, causing the distant end to start ringing.

2 2. System Application and Ordering 2.1 Purpose This chapter is designed to assist the engineer in determining the exact bill-of-material required to assemble a complete network of FOCUS nodes. The reason for building such a network is to provide an efficient method of transferring data from one place to another. For the purpose of this chapter, “data” is meant to include all types of channels including voice, RS-232, 64K, protective relay contact closures, etc.
FOCUS System Manual The choice of whether or not fiber will be available to the user for a particular link between nodes and even whether or not a particular node will be installed depends on the up-front planning and economics for the installation. This section assumes that there are no limitations to routing or node locations, as these decisions may be dependent on many factors.
Chapter 2. System Application and Ordering 2.2.1.2 Permissive and Direct Transfer Trip Systems A function on the Protective Relay Interface (PRI/PRS) Module may be used to provide a transfer trip function (permissive or direct). These systems normally are designed such that they will accept a form A contact to key the FOCUS system to a trip state. This causes contact closure at the remote terminal that can be used for tripping.

3. Installation 3.1 3 Installation Notes A FOCUS chassis is typically shipped assembled, with all common equipment, channel modules, and module interfaces already installed. In most cases, the correct software configuration (e.g., synchronization, module settings, channel assignments) for the installed equipment has also been done and is stored in the Maintenance Module of each chassis. If your chassis came already assembled (i.e.
FOCUS System Manual Inspect the condition of the FOCUS equipment as you remove it from its cartons. You must report any damage to the FOCUS equipment to the carrier. Damages are the responsibility of the carrier, and all damage claims are made good by the carrier. Send a copy of any claim to: AMETEK 4050 NW 121st Avenue Coral Springs, FL 33065 USA Attn: Quality Department 3.1.
Chapter 3. Installation connections for the chassis, the common equipment, and the individual channel modules. The connectors for the chassis and the common equipment are on the left-hand side of the motherboard. 3.2 Installation Summary This section provides a summary of the FOCUS installation process.
FOCUS System Manual directly to the DS1 interface, labeled “P2,” on the motherboard. In addition to the system connections, you must also connect the proper wiring to the channel module interfaces, which are plugged into the connectors on the right-hand side of the motherboard. On their “inside” face, these interface modules all have the same DIN connector, so that you can connect them to the back of the motherboard.
Chapter 3. Installation If you have both main and standby Power Supply Modules and a single power source, connect the wiring from the ac or dc power source to screws 1 and 2 on the terminal block on the rear of the chassis (see Figure 3-1). For convenience, these positions are labeled MAIN POWER. Also connect the power source to the standby power supply, screws 3 and 4. Note that positions 3 and 4 are labeled STANDBY POWER. You must also connect the ground screw to an electrical ground.
FOCUS System Manual NOTE If, when you install a dual transceiver, you connect just one of the transceivers—saving the second transceiver for future use—you must jumper the unused transmitter to the unused receiver using an external jumper. If the chassis input/output interface is electrical (i.e., if it has one or more DS1 Transceiver Modules), make the connection as follows: Connect the interface cable directly to the DS1 interface, labeled “P2,” on the motherboard.
Chapter 3. Installation modules is entirely up to you. Note, however, that you must match each channel module up with its interface on the rear panel. 3 To install each channel module, carefully insert it into the top and bottom grooves of an open slot. The grooves are marked with black lines for ease in alignment. Slide the module all the way in until it is well seated in the slot. Lock it into place using the black inject/eject lever on the front of the module.
FOCUS System Manual Windows, please consult the documentation that came with it. Before installing the FCS, it is recommended that any previous version of FCS be removed (uninstalled). The uninstall operation is available via the Windows’ Control Panel “Add/Remove Programs” Icon. Note: When you uninstall FCS, the sub-address file, SUBADDR.TXT is also removed. Before uninstalling, you may want to copy and save this file so that you will not need to create a new one. 1.
Chapter 3. Installation 3.4.5 Alternate PC connection FOCUS chassis with maintenance module version 4 & 5 provide an alternate PC connection using a special cable (see figure 3-5). Using a cable wired exactly as shown you can connect your PC to the female DB-9 connector on the rear of the motherboard. The connector, labeled “P4” is located just above and to the left of the terminal block. If you use any other cable your PC will be damaged severely.

5. Alternate Path Mode (APM) 5.1 Description The Alternate Path Mode (APM) feature gives FOCUS the ability to detect a T1/E1 break on a closed loop and reroute the affected channel data around the opposite side of the loop, using the same time slot (a time slot may be used only one time within a loop). The FOCUS network consists of network nodes (FOCUS chassis) connected in one or more paths.
FOCUS System Manual neighbors’ addresses into FOCUS, the entering of the loop definitions, selecting channels to be skipped, and sending the ARM and DISARM APM message. 5. No more than one (1) loop fault can be tolerated at a time. A loop fault is defined as a broken link between two nodes in one or both directions or a failed FOCUS terminal. A broken link condition can be a broken fiber or wire or a bad transmitter or receiver at either end of the link.
Chapter 5. Alternate Path Mode (APM) Where xxxx is the chassis address (terminal ID) of the node which prevented APM to arm, and yyyy is the reason the node at address xxxx failed to arm. It will be one of the following: • • • • • T1/E1 Bad Inactive Node Wrong XID Time Out Address Mismatch Refer to Table 5-1 for help in troubleshooting the problem. 5.1.2 How to Disarm a Loop The APM Loop may be disarmed at any time.
FOCUS System Manual Table 5–1. Reasons for Failure of APM Loop to ARM. Reason recorded in target Explanation User Action T1 Bad The node at the given address has an T1 error on at least one side of the loop definition (possibly both sides). This reason is reported if any of the following T1 states are present at the time the “APM Arm” command was received: Repeat the “APM Arm” command. If the same reason is repeated, go to the node that matches the address and fix the T1 problem.

Alternate Path Mode (APM) and “X2-1 to “X2-2.” Note that if you set the loop definitions in this example to “X1-1 to X2-2” and “X1-2 to X2-1” the loop might arm, but APM would not operate correctly. 5.1.4.9 Minimizing Sync Slips with Two APM Loops ARMed A FOCUS chassis with two dual transceiver modules can be part of two APM loops, and you can protect both loops with APM. In some situations, however, sync slips may occur when one or both loops are in alternate path mode.
FOCUS System Manual Scenario 4 This scenario, (Figure 5-9), shows what will happen if none of the FOCUS chassis in a twoloop system is programmed as the master. Here, spur chassis 305 is the programmed master of the system. Figure 5–7. Two ARMed APM Loops – Scenario 2. Scenario 3 This scenario, (Figure 5-8), shows what will occur if the FOCUS chassis functioning as the common chassis of a two-loop system is not programmed as the master. Here, chassis 532 is the programmed master of the system.
Chapter 5. Alternate Path Mode (APM) When APM is activated, each chassis around the loop will skip the same channels you selected here. When should you skip a channel? When you have a channel assignment that is not supported by APM. This is true if: 1. A channel is used for more than one connection around the loop. 2. A PLD connection is made, and the next time slot is not cleared around the entire loop. 3.

17. Pilot Wire Interface (HCB/SPD) Module 17.1 Description 17.2 Application The Pilot Wire Interface Module connects directly to the HCB, HCB-1, or SPD relays. It monitors the voltage and the current of the connected pilot wire. The module is designed for use with either Westinghouse/ABB HCB and HCB-1 relays or the General Electric SPD relay.
FOCUS System Manual Figure 17–1. HCB/HCB-1 Interface Module for Two-Terminal Applications. CAUTION ! Because the switches used in the metallic pilot wire application are not designed to work at low voltages and currents, they can create more problems than they help solve. A small amount of oxidation on the switch contacts will have a large effect on system operation. You can make your system more reliable by removing the test milliammeter and switch.

19. Party Line Data (PLD) Module 19.1 Description 19.2 Application The Party Line Data (PLD) Module provides “multi-drop” RS-232 data communications over a single DS0 channel. It occupies one physical slot in the FOCUS chassis. The module’s interface has a single DB9 female connector (DCE) for directly connecting your RS-232 device. The PLD system does not support hardware handshaking. If handshaking is required, RS-232 channel modules (232) must be used.
FOCUS System Manual the remote device; with internal addressing, the master unit uses the address of the PLD module to which the target device is attached. Following are descriptions and examples of both types of applications. 19.2.1 Applications Using External Addressing The most typical application for the Party Line Data (PLD) Module is a network of polled RTUs. Figure 19-1 shows a typical application using external addressing.
Chapter 19. Party Line Data (PLD) Module 19.2.2 Applications Using Internal Addressing The PLD Module’s internal address mode capability enables you to make remote connections to RS-232 devices that do not have their own internal address capability. Some examples of these devices are smart switches, meters, and other IEDs (Intelligent Electronic Devices). A typical PLD application using internal addressing is shown in Figure 19-2.
FOCUS System Manual At the location where the Master device is connected, configure the PLD module at this terminal as the “Head” module. To configure the “Head” for internal addressing, the module must first be mapped to a DS0 channel. Mapping of the “Head” module is accomplished by a single mouse click on the module end and a double mouse click in the desired T1/E1 stream and DS0.

FOCUS System Manual Figure 20–1. Sample Internal Network within a FOCUS Ring Configuration. Here’s how it works: The network operates on a “first come, first served” basis, allowing one station-to-station call at a time. This means that the first person to pick up one of the phones on the network will hear the network dial tone and be able to place a call as described below.
Chapter 20. Addressable Two-Wire Voice (PBW/PBT) Module Figure 20–2. Sample Internal Network with PBX Connection in a FOCUS Ring-with-Spur Configuration. you can instruct the other stations to hang up and then place your emergency call. For a conference call, all three parties can simply stay on the line. Other stations on the network can join the conference using the same procedure. If desired, all the stations on the network can join the conference.
FOCUS System Manual • Ring all stations on the internal network simultaneously from any one station on the internal network or from any extension on the PBX • Break in, or interrupt, an ongoing call involving any of the stations on the network (for an emergency or a conference call) either from any of the other stations on the internal network or from any extension on the PBX How it works: The basic operation of the “internal” portion of the network is the same as described above.

Chapter 20. Addressable Two-Wire Voice (PBW/PBT) Module Table 20–2. PBW/PBT Module Specifications.
FOCUS System Manual Assigning the DS0 time slots for the first module/chassis in the chain For the first chassis in your network, you must map the module’s voice channel “b” to an unused time slot. This prevents any “idle” noise on the line. If your system is in a loop configuration, map the module’s voice channel “b” to an unused time slot in the transceiver stream coming from the last chassis in the loop (i.e., a time slot that is not mapped in that chassis).
Chapter 20. Addressable Two-Wire Voice (PBW/PBT) Module if the module is functional and red if the module is non-functional. The remaining four LEDs, beginning at the top left, work as follows: PBX CH BUSY – This green LED, when lit, indicates that the (network) line is busy. The line becomes busy as soon as any phone on the network is lifted off the hook. BREAK-IN – This green LED is lit when a user enters the break-in code (#00) on the phone connected to the module.
FOCUS System Manual Pick up the phone at one station. When you hear the network dial tone, dial the number for the other (i.e., any other) station with a PBW module connected to a telephone. Have someone pick up that phone when it rings. Make sure you can talk to each other and then hang up. Have the person at the other station call you.
