Radio Control Board

One of the circuit boards plugged into the backplane, which provides the interface between the controller and a radio transmitter and receiver combination or any other audio signal source and destination, such as an IRLP node or telephone interface.

Port

Generic term for one full duplex connection to the controller. This could be a repeater, a link to another site, and IRLP node, or a remotely controller transceiver (remote base).

Physical Port Number

The Radio Control board farthest to the left in the card cage, and next to the CPU board is designated physical port number 0, the Radio Control board immediately to the right of physical port number 1, and so on.

Logical Port Number

Users need to control the system by commanding specific ports, using the port number. For example, the user may want to disconnect Link 1 at the San Francisco Bay area Black Mountain site which links to another site at Crystal Mountain. He would issue the Link 1 OFF command to do this. There may be situations where the port number that a user associates with a particular link cannot be the same as the physical port number. As a system grows, or if there is a problem with the hardware for one of the links, it is undesirable to change the logical port number for a link to some particular other site, but it may be necessary to change the physical port number attached to that link. The controller provides a logical to physical port mapping that can be used to make the logical and physical port numbers different.

Repeater or Local Radio or Repeater Port

A port which is configured to operate as a repeater. Signals coming in on its receiver will be repeated back out its transmitter.

Link or Link Radio or Link Port

A port which is configured to operate as a link. Signals coming in on its receiver will not normally be repeated back out its transmitter, but only to other ports which are connected (“linked”) to this port.

IRLP Port

A port which is configured to operate as a restricted link, normally used for IRLP or other voice over IP connections into the site.

Remote Base Port

A port which is configured to operate a remotely controlled transceiver. It invokes special telemetry, and is most commonly used in a simplex mode. The
