Features and Programming Options

When any MC-IP-ODC Operator Desk Console selects a Station to have a conversation,
either Master to Master (MC-IP-ODC to MC-IP-ODC) or Master to Station (MC-IP-ODC to
MC-IP-116), the MC-IP-HOST sees if that Station is available. If not, the requesting Station
is sent a "Busy Signal". If the Station is available a connection is established between the
two devices and the ODC is in control of the conversation. If a remote Station pushes their
call button a message is sent to the HOST requesting and intercom call. Any calling Station
can be sent to one or more Operator Desk Consoles (ODCs) at the same time for answering
this is known as a "Hunt Group". This is configured for each Station. Call routing and feature
options are stored in the MC-IP-HOST (HOST) for call processing.
Call Processing
Calls are typically generated from a Station. When a Station places a call, a message is sent
to the HOST for processing. Independent timers are assigned and started for each new call
and the call is then put into the Call Queue. Depending on the calling Station configuration
and the state of the MC System, the HOST rings the ODC's that were configured for that
Station. An ODC will only ring when they are able to take the call, i.e. the ODC and the MC-
IP-116 (116) are not busy. An ODC is considered "busy" when it is in a page or on a call. A
116 is considered "busy" when any Station on a 116 is in a call. If any Station on a 116 is in
a page, the 116 is not considered "busy". In this case, an ODC will ring and can even connect
the call, however, the page will override the call.
Master to Master (ODC to ODC) calling has two options which are configured for each ODC.
An ODC can be "Automatic" meaning that if it is not busy, and another ODC wants to talk to
it, the voice channel will automatically open as if the calling ODC had called a remote Stations
such as a door or a cell. In this case the calling ODC is in control of the Push To Talk function
and call ending. If Privacy is turned on, the receiving ODC will hear a beep tone before the
calling ODC hears any audio. However, if an ODC is set to "Manual" any ODC calls will be
processed as if a remote Station were calling and the receiving ODC will have to answer it.
In this case the receiving ODC will ring. To answer the call, the receiving ODC will generate a
call to the originating ODC. At this point the "receiving" ODC is now the master and normal
ODC to ODC communications are handled as stated above.
Call RELAY (what the Telephone Industry calls "Circular hunting")
Call relaying is a feature which redirects a call to another ODC. In the MC-IP the Call Relay
is configured for each Station with up to two RELAY ODC's. The call processing for Call
RELAY is determined by the configuration. The configuration is independent for each Station.
There are four aspects to Call RELAY, Call Time Out, RELAY 1, RELAY 2, and RELAY
Enable. See below for a better definition.
If a Station that is calling my ODC is relayed to You, and you are on a call, the call will still
be pending for you, however, your ODC will not ring. Anytime a new CALL comes in an
independent Relay timer is started.
If a CALL comes in to an ODC and the ODC is "busy" in a page or on a call, the new call is
in the Queue and a message is sent to "their" system visually indicating the Call, but the ODC
will not ring.
