The assigned working channel GETC receives the end of call signal from the calling radio and sends end of call information to the Site Controller When the Site Controller receives the end of call information or the conversation time limit is exceeded it first directs the channel connected GTI to extract itself from the audio loop of the assigned working channel then directs the line connected GTI to hang up the line and finally directs the assigned working channel GETC to terminate the call 65 LBI 38985B MULTIPLE CHANNEL PARTITION DESCRIPTION Multiple Channel Partition MCP is an optional feature of the EDACS Site Controller This feature requires no additional hardware but must be enabled at the factory can t be enabled through the System Manager The MCP option allows selected sets of channels partitions to be set aside for exclusive use by selected sets of users one set of channels for each set of users Backup sets of channels may also be set aside for alternate use by these selected sets of users to be used when a Working Channel is not available within the primary set of channels and the configurable condition for use is met Up to 15 partitions may be set aside defined for each system that is under the direction of a Site Controller One primary and up to three backup partitions may then be selected for each Logical unit ID LID and Group ID GID LIDs and GIDs may individually be MCP enabled Wh

27. LBI 38985B assignments to be covered later can sometimes be used to reduce the effects of partitioning on access time Partitioning can be used to set aside a specific set of channels to be used exclusively by a specific set of users This specific set of users may then experience an increase or decrease in access time more or fewer queued calls If this specific set of users experience a decrease in access time fewer queued calls as a result of the partition it is likely that the remaining users of the system will experience an increase in access time more queued calls The following general rules apply to the effect of partitions on access time e After the addition of a partition to a system some possibly all users will experience more queued calls e The smaller the partition the more calls will be queued NOTE In general the more partitions that are defined for a system the more often calls will be queued A partition containing a single channel will have no channel available while a background test call is being performed Although the partition assigned to a specific channel in one system does not need to be the same as the partition assigned to the same channel in another system and a partition that is defined in one system does not need to be defined in another system it is best to keep all systems in a network configured as similar as possible When you later assign IDs to these partitions
