Individual Calls

These are private (not secret) calls made between one radio user and another. In most instances all these calls would be within the same fleet. Should calls be required to be made between fleets, additional interfleet and interprefix codes will have to be entered. When the call is made, an indication of the availability of the called party is given i.e. busy, available or not available. The length of the call will be limited to ± 3 minutes as set by the system manager.
Priority Calls

A feature of the Network is the set-up of priority calls. This means that precedence is given to a caller with enabled priority call set-up to be allocated the first available channel and not stay in the queue for the next available channel.
Emergency Calls

A feature of the Network is the enabling of emergency calls to selected users at an extra cost. An emergency enabled user will be given preferential treatment by having a channel allocated to him which is still in use on a high site with the longest timeslot user being knocked off the channel.
PSTN / PABX Calls

As a special feature, PABX interconnect to customers are available. Trunked radios can connect to a cellphone- or telephone network and vica versa through the PSTN Network. Both shortform and longform access to as many as 24 PABX lines routed via 8 exchanges is provided for inbound and outbound traffic into the trunking network. The interface to the PABX can be either E&M or loop disconnect with both DTMF and 10 i.p.s. dialling. Shortform PABX is available to any one of 4 different exchanges, although extension numbers are limited to 4 digits. In order to provide as much flexibility as possible, there is an interpretation table for the 4 combinations to produce any single BCD digit 0-9. Longform PABX allows for a maximum of 9 digits to be uploaded from the radio unit. The shortform PABX, routing table and shortform PABX digit stripping options may be configured.
Talk Group Calls

A group call can be set up to enable users in the same fleet to talk to one another. This normally will only take place on a single site i.e. everybody covered by that site in that fleet will be able to participate in the conversation. In certain special instances two- or three site calls will be allowed.

Broadcast Calls

The difference between a group call and a broadcast call is that during a broadcast call none of the activated radios can talk back. This type of call is typically used for announcements of whatever nature.
Call Logging

Call logging on the network is achieved by storing detail of the calling- and called radios in the memory banks of the network. This data is then later retrieved and translated to meaningfull data expressed as date time stamped prefix and ident information. Every single call made on the network is therefore traceable.
Call Diversion

Calls can be diverted from one mobile to another without the caller being aware that this process has taken place.
Comprehensive Queuing

Comprehensive queuing is an unique feature of a trunked radio network. This feature enables a user to obtain information from the display of his radio that his call has been accepted by the network and is waiting for a channel or called party (Status calls and SDM's only) to become available.
