CTI Products, Inc. Overview
1. System Overview
Hot-Standby EXB Network Extender Modules are used when added reliability is required in monitoring and controlling remote comparators. They work with CTI Products' MCN Monitoring and Control network. They provide a hot-standby dual path for the monitoring and control data.
The EXB Network Management Software runs on a PC and monitors the status of the Hot-Standby EXB modules and links. It provides the following functions:

Figure 1 Hot-Standby EXB System with Network Manager PC
Figure 1 shows a typical Hot-Standby EXB system with a Network Management PC. It shows hot-standby channels to two remote sites. Not shown on the diagram are CIB modules at the remote sites or the MCN Remote Comparator Display (MCNRCD) PCs.
The figure shows a Network Management Router. These routers are used in large systems that have multiple MCN networks. In these cases, the Network Management PC sits at a higher tier than the MCNRCD PCs and manages all Hot-Standby EXB modules that feed its MCNRCD PCs. In smaller systems with only one master central network, the Network Management router is not needed.
Figure 1 shows Serial EXB Modules with two ports each. The system could contain a mix of Serial and Analog (Telco) EXB modules, depending upon the WAN links available to the remote sites. Analog (Telco) EXB Modules have only one port each. The second port on Serial units may only be used at the Remote side.

Table 1 EXB Modules
Table 1 shows the various types of EXB modules that can be used in a system. The "xxx" in the model number is the revision number. The revision must be 300 or above to be used in a hot-standby system. The Hot-Standby function of these units must be enabled with special programming provided by CTI Products, Inc. as part of a Custom Engineered System. 78K EXB modules are typically used at the remote sites. 1.25 Mb units are typically used at the central sites, although 78K devices could be used in some systems.
The EXB Network Management Software runs on a PC separate from the MCNRCD PC(s). The software package includes a Network Interface card for the PC.

If a system has multiple PC monitoring points, it can have an EXB Network Manager at each PC location. Each Network Management PC can control only those EXBs that bring data from remote sites to its own (Central) site.
For example, Table 2 shows a system with monitoring points at Site 1 and Site 2. A Yes in the table indicates that the PC can monitor the appropriate "Remote" (CIB or Group) EXBs. Notice that Site 1 cannot monitor the EXBs at its site that feed CIB data to Site 2, and vice versa.

2.1 Definitions
EXB Channel Everything required to implement a
Hot-Standby EXB Link, including:
-Central Main EXB
-Central Standby EXB
-(2) Remote EXB
-Main & Standby WAN Lines
-Central MCN Tie Line
-Remote MCN Tie Line
Central Site The location of the MCNRCD PCs
and the EXB Network Manager PC. This is the site receiving the data from the remote CIBs.
Central EXB One of the EXB modules at the central site
(where the MCNRCD PCs and the Network Management PC are)
Central EXBs are sometimes referred to as "Network EXBs" since they are tied to the MCN network backbone at the MCNRCD location.
Main EXB This is the Central EXB that normally passes traffic.
Standby EXB This is the Central EXB that is normally in the Standby
mode. It only passes traffic when a fault is detected.
Remote Site This is the location of the CIB modules that are sending
their data through the EXB Channel.
Remote EXBs One of the EXB modules at the Remote Site. These
may be referred to as the "Remote Main" or "Remote Standby" EXB to identify which WAN line it is connected to.
They are also sometimes called "Group EXBs" or "CIB EXBs" since they are associated with CIB modules in a particular MCN group.
WAN Line This is the connection between the Central Site and the
Remote Site. There will be a Main Line and a Standby Line. These lines may be analog (leased telephone lines) or Serial Asynchronous (RS-232) lines, depending upon what type of EXB modules are used.

CTI Products, Inc. EXB Operation
Central MCN Tie Line This is the MCN network cabling between the Main
EXB and the Standby EXB. Although it is shown as a single logical jumper in the program and on diagrams, there may actually be a number of jumpers between the Main and Standby EXBs, depending upon the exact equipment mounting.
Remote MCN Tie Line This is the MCN Network Cabling between the two
remote EXB modules in a channel. Although it is shown as a single logical jumper in the program and on diagrams, there may actually be a number of jumpers between the two EXBs, depending upon the exact equipment mounting.
Control Neuron The processor in the EXB that controls the data flow.
2.2 Operation
The system normally passes data on the Main link. If a failure is detected, the Standby half of the channel is enabled.
System testing proceeds as follows:
1. The Main EXB module continuously probes its Standby EXB over the WAN lines.
2. The Standby EXB sends a Probe Acknowledge over the WAN lines.
3. When the Main EXB receives the Poll Acknowledge, it issues a Holdoff command to the Standby EXB over the Central Tie Line.
4. If the Standby EXB receives the Holdoff command, it will keep its channel switch turned off. It also sends a Holdoff Acknowledge to the Main EXB.
5. If the Standby EXB does not receive a Holdoff command within a fixed timer period, it enables its channel switch, passing data to and from the Remote site.
The Hot-Standby EXBs can operate without intervention from the EXB Network Management Software.
Each EXB in an EXB Channel has custom configured addresses so that the Control Neuron in the Master and Slave EXBs know the address of each other. These addresses are entered in the EXB Network Management Software Configuration Program so that the EXB Network Management Software knows the addresses of each EXB in a channel.

3. Hardware Installation
3.1 MCN Hardware (EXB Modules) Installation
Hardware must be installed in accordance with the following documents which are listed from most system-specific to most generic. In the case of any discrepancy, the documents first in the list shall take precedence.
1. Customer Specific System Diagrams and Configuration Documents CA-xxxxx-xxx Drawings KA-8xxxx-xxx Custom Configuration Disks
2. MCN Monitoring and Control Network Engineered System Installation Manual
Part Number S2-60650
3. MCN EXB Network Extender Manual
Part Number S2-60596
4. Monitoring and Control Network System Manual
Part Number S2-60425
Since all EXB modules have custom addresses, they must be installed as per the customer specific documents.
If a system is pre-configured at the factory, the EXB modules will be labeled appropriately.
If a system is not pre-configured, the EXB modules must each be programmed appropriately with the custom scripts provided in the Customer Configuration Disk(s). See the instructions with the Customer Specific System Drawings.
When Serial EXB modules are used, be sure to set the Baud Rate switches on the back of the units to the WAL Line data rate being used. 19.2K or higher is recommended. Be sure to use Asynchronous Serial channels for the WAN line.
When Analog (Telco) EXB units are used, be sure to set the wireline 2W/4W ,TX Level (-10 / -16 dBm), and Answer/Originate option switches as appropriate (see Customer Specific information and the EXB manual.)
3.2 Serial EXB Dual Port Use
Serial EXBs have two serial ports. The following rules govern the use of those ports:
1. Remote EXBs (CIB EXBs) can use 1 or 2 ports. They can feed multiple MCNRCD display positions. If two EXB Network Management Software PCs are running, both can see this remote EXB.
2. Central EXBs can use only 1 port.

6.8 System Status Analysis & Example Screens
The EXB Network Management Software program tries to analyze the system to the best of its ability. It presents its best guess as to what is wrong in the system.
When a Main EXB notices a change in state of its Standby EXB, it will notify the program. The program will start an analysis on that EXB channel.
It will try to communicate to all EXB units first in the forward direction (Clockwise -- the Probe direction as shown in Figure 3).
It will then try to communicate to all EXB units first in the reverse direction (Counter-Clockwise -- the Holdoff direction as shown in Figure 3).
It can take about 5-10 seconds to analyze a failed EXB channel.
Based upon the responses, the program will then determine what the most likely failure is. Do not take its recommendations as absolute truth. Sometimes there are other failures that can result in the same display. The program is presenting the most likely problem. Some alternate problems are shown in the following status displays.
6.8.1 Normal Status
