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 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.

This is the site receiving the data from the remote CIBs.
Central EXBOne 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 EXBThis is the Central EXB that normally passes traffic.
Standby EXBThis is the Central EXB that is normally in the Standby
mode. It only passes traffic when a fault is detected.
Remote SiteThis is the location of the CIB modules that are sending
their data through the EXB Channel.
Remote EXBsOne 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 LineThis 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 LineThis 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 LineThis 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 NeuronThe 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.

traffic would pass through the bottom path.
7. If break was at Point B, both EXBs would be passing data.
MCN traffic to/from the In port of the top Remote EXB would pass via the top

would pass via the bottom pair of EXBs.
8. If the break was at Point C, the standby EXB would still close its switch, but there
would be no traffic over the bottom path. The Standby EXB would know that the
link was down because of its link layer diagnostics.

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

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.

Turn off the PC and remove the power cord.
Open the PC case and locate an empty slot.
Remove the corresponding blank panel from the rear of the PC.
Insert the Network Interface card into the slot, ensuring that the
edge connectors are fully mated, and the slot in the rear panelmounting lug of the Network Interface card is aligned with the
threaded hole in the PC chassis.
Replace the screw to hold the card firmly in place.
Close the PC.
Reinsert the power cord and then restart the PC. A “New
Hardware Found” window will be displayed briefly when the
operating system recognizes the Network Interface card.
The S2-60617 MCN Adapter Screw Term to Dual RJ-45
has a pluggable screw terminal installed on it, but it fits only the
PCLTA module. The EXB Network Management Software
Network Interface uses a different terminal strip. Remove the
terminal strip from the adapter and attach the cable to the screw
terminal that ships with the Network Interface card.
