MoCCA consists of the following units:
A base unit, about the size of a small laptop computer which is connected to a remote server wirelessly through a CDPD connection. Located in the FSE's toolkit, the base unit has a large color display for viewing large schematics.
A cellular phone is tethered to the base unit and communicates wirelessly with the local cellular provider.
A hand carried satellite unit which is in communications with the base unit in the FSE's toolkit. The satellite unit displays the contents of the base unit screen. The satellite unit weights less than 0.75 pound.
A wireless microphone and headset combination which is wirelessly linked to the cellular phone.
The software architecture uses a thin client approach to minimize the amount of software on the mobile base unit by exploiting web-browsing technology and a wireless CDPD Internet connection to communicate with a server. The satellite unit is not running the browser, it is merely displaying whatever is currently on the base unit display.
There are six buttons defined for the user interface. The Bboard button provides access to a phone-based voice bulletin board where FSEs may asynchronously collaborate to solve problems. The Calls button accesses the summary of active field service calls for the engineer. The Phone button invokes an auto-dialer keypad. The FSE button brings up a directory of FSEs and the Availability button shows their current status. The Pager button accesses the list of current Pager messages. The FSE directory, Pager message list, Calls list, and Availability form are all web pages, generated automatically from various field service databases.
