If a CALL comes in to an ODC and the 116 is "busy" in a call, the new call is in the Queue
and a message is sent to "their" system indicating the Call, but the ODC will not ring. ODC's
will only ring when they are able to take the call, i.e., the ODC and the 116 are not busy.
When any Station on a 116 is in use, all Stations for that 116 are tagged as busy.
Call RELAY Processing
When RELAY Enable has been configured, calls are placed in a hybrid "Circular hunting"
loop. Depending on the configuration, a loop consists of up to three steps. The first is the
initial Hunt Group of ODC's, the second is the RELAY 1 ODC, and the third is the RELAY 2
ODC. When a new call is placed, one of the timers that were assigned was the Call Time
Out. If a call is unanswered for the duration of the timer, the call will advance through the
loop and the timer will be reset. Once the end of the loop is reached the process starts over.
Typically, during this process, only the active loop ODC(s) will ring, however, there is a
configuration option (Ring Local) that will keep ringing the initial Hunt Group until the call is
answered.
Call Forward All
Is where the ODC is out of service for some reason and all calls are to be rerouted to another
ODC. This is a system command that is set up in the control system (Touch Screen) so that
the Operator can put their console out of service. When a console is out of service it just
means that their calls will ring somewhere else. The visual call status is still broadcast to all
control screens and can still be displayed as long as the touch screen is still on. It is
suggested that the Touch Screen Icon be programmed to reflect that the ODC is in Call
Forward All mode.
Call Forward Processing
An ODC can only use forwarding if it has been configured to allow it. When a forward is
created, it will only be created if it does not create an endless forward. For example, if ODC-
a is forwarded to ODC-b, and ODC-b to ODC-c, and ODC-c to ODC-a, any call to any ODC
would be in an endless loop and never ring anywhere. To avoid this, the system will not allow
a new forward until a section of the loop is broken. In the example above, the last forward
would fail. This means that any forward not needed should be removed before a new one is
created. In the example above, the last forward was put in because ODC-a is back from
lunch. So ODC-a to ODC-b would be canceled, then ODC-c to ODC-a created.
Console Call Enables (aka Hunt Groups) - Calls can be to a single ODC or to multiple ODCs
in a Hunt Group. Hunt Groups on the MC-IP are set up for each Station and are not system
wide.
