Abstract

In a wide area system with a centralized audio switch (refer to figure l), the creation of channels consists of mapping base stations to audio slots. Currently, this map- ping is done manually by a user. The. user must know how many base stations and audio slots are present and determine how they should be mapped to one another. This procedure must be repeated each time a new sys- tem is installed. Errors can be introduced ifthey are not mapped correctly and as a result, the audio could be mis-routed or lost. Elimination of errors encountered during manual configuration (mapping) of base stations to audio slots can be accomplished by automating the. process.

AUTOMATIC CONFIGURATION OF BASE STATIONS TO AUDIO SLOTS

by Christina M. Hartley, William A. Felderman, and John W. Maher

  In a wide area system with a centralized audio switch (refer to figure l), the creation of channels consists of mapping base stations to audio slots. Currently, this map- ping is done manually by a user. The. user must know how many base stations and audio slots are present and determine how they should be mapped to one another. This procedure must be repeated each time a new sys- tem is installed. Errors can be introduced ifthey are not mapped correctly and as a result, the audio could be mis-routed or lost. Elimination of errors encountered during manual configuration (mapping) of base stations to audio slots can be accomplished by automating the. process.

  Automatic configuration of the channels in this sys- tem consists of three steps. The first step is receiving the hardware status of the sites and base stations in the sys- tem via the remote site data link to the fLxed end con- troller. The second step involves receiving the hardware status of the audio switch. This consists of a physical board address and Tl/El synchronization confirmation from each site interface board within the audio switch to the fixed end controller. The third step is determining which site interface board address and slot number a given base station has been physically wired to.

  Once the hardware status of the audio switch and at least one sites worth of information is received, the con- figuration of the channels can begin. Starting with the fust audio slot which is not already mapped to a base station, the audio slot is set to "loopback? In "loopback' a tone generated at the base station is sent to the audio switch and is retransmitted by the site interface back to the base station in the same slot number. All other non mapped slots are programmed to "non loopback:' A message is sent to the base station that...
