Study Notes

Call Management Features

Calls unanswered within a set timeframe automatically transfer to a designated Controller.
Incoming Priority Alert Calls trigger a pop-up with Train ID and location, enabling the Controller to acknowledge and initiate two-way communication.
Traffic Controllers can participate in active calls through 'Call Inclusion', employing pre-emption and forced call clearing capabilities.
Group Patching allows for handling call authorization for specific calls or users; configurations of Patch Groups can be pre-stored on the desktop for easy access and modification.

User Identification and Communication

RCW displays 'Calling Line and Connected Line Identifications' to show user identities and associated Radio Base Stations.
Late Entry Facility accommodates users who are busy or unavailable during group calls.
'Call Hold' functionality is included in RCW to manage call interruptions.

Call Forwarding and Group Call Dynamics

RCW enables call forwarding to another Controller if the original is busy or non-responsive within a designated time.
Users can belong to multiple Call Groups, with local areas for Group Calls adjustable within the Network.
Only one member can speak at a time in a Group Call, though Controllers can interrupt as needed; calls operate in half-duplex mode.

Specialized Call Types

Broadcast Calls are one-way communications from a single user to all in the same Call Group, initiated only by OCC/DCC.
Emergency Calls can be initiated by Train-borne Mobile, Hand Portables, and Control Centres, categorized into:
- Train Emergency Call, automatically routed to the designated Traffic Controller.
- Other essential identifiers displayed on the Radio Control Head post successful log-on.

Hand Portable Radio Features

Hand Portable Radio users can initiate calls to other users and control centres based on their access level.
Functional identity of the calling party/group is indicated through short audible and visual cues.

Types of Calls via Hand Portable Radios

Individual Calls are private, one-to-one conversations not audible to other users.
Group Calls allow users to talk to a selected group after obtaining permission indicated by audio and visual signals; out-of-range notifications are provided for users who stray from the call area.
Users cannot speak during a Broadcast Call but are informed of this restriction.
