NETWORK CONFIGURATION (See Figure B3)
C ONFIGURATION is used for programming the DXC901 or the DXA100. The configuration
programming is stored in nonvolatile RAM in the DXC901 or DXA100. This is the way the network
recognizes how to handle and manipulate events from substations on the Tridex system.
Since Crisis Alert and Tridex Intercom are two separate stand alone systems working as one, there
has to be an interpreter to allow Tridex to communicate with Crisis and vice versa. The Digital
Exchange Controller (DXC901 in a CB901 system) is the device that interfaces the Crisis System
to the Tridex Intercom. It is necessary to program the DXC901 so that when an event is initiated
from the substations, the Crisis System will know how to handle it. The DXC901 monitors the I/T
bus and can identify activity in the intercom system. Based on the DXC901's programming, these
activities can be ignored or intercepted and handled in accordance with it’s programming. The
DXC901 can dial on behalf of any station in the system. For example a master station dialing a
substation, or a substation dialing program distribution.
The DXC901/DXA100 has a list of information for each subscriber in the Intercom Central it is
installed in. This list is referred to as the Subscriber Address Record (SAR). The SAR contains all
pertinent information regarding the station and how Crisis Alert is to handle any activity. It also tells
the DXC901/DXA100 what number to dial for that station when required.
When entering C ONFIGURATION , the SAR template and the option list will be displayed. The program
waits for a selection of one of these options. Only the first letter of the option name must be entered
followed by carriage return (ENTER key).
The rest of this section makes reference only to the DXC901 however, it also applies to the DXA100.
