RAN machine. Multi-Channel RAN routes do not support the cross connecting (daisy chains)
of multiple trunk ports together so that several callers hear the same RAN message.
Multi-channel machine types - Continuous Mode Multi-Channel (MCON), Pulse Start/Stop
Multi-Channel (MPUL) and Level Start/Stop Multi-Channel (MLVL) – are not linked to a RAN
machine or a given trunk. All trunks belonging to the RAN route are considered independent.
RAN trunks and RAN machine channels are connected one-to-one. If one RAN trunk is
detected as faulty, then all other trunks are not impacted.
For the RAN machine types, the maximum length of the recorded announcement is two hours.
The meaning of a ground signal received from the RAN machine (play or idle) is configured in
LD 16.
Multi-Channel Level Start/Control Mode (minimum vintage BA)
A RAN mode of operation is available called "Multi-Channel Level Start/Control Mode." This
mode enables provisioning of multiple RAN channels for a RAN route (playing the same
message independently on demand) cross-connected one-to-one to each RAN trunk in a multi-
channel level start RAN route. Do not bridge RAN trunks in a multi-channel RAN route.
The Route Data Block LD 16 is used to configure a RAN route in Multi-Channel Level Start/
Control mode, using the following response:
RTYP = MLSS
Trunk members are provisioned in the Trunk Data Block LD 14.

Continuous operation mode
In the continuous operation mode (sometimes called the Audichron mode), a message is
constantly played, over and over again. Callers "barge in" on a playing message or receive a
ringback tone until the message plays again. The start line (ST+) is hardwired as always active.
See
Figure 129: RAN control signals (Control GRD = IDLE)
on page 414. At the end of each
message, a pulse is issued on the "C" line that is used by the trunk unit to cut through to the
waiting call.
Note:
The "B" (busy) signal line indicates availability of an announcement machine message to
the trunk unit when configured for the continuous operation mode. This signal is made active
(ground) by the announcement machine if the channel contains a recorded message and is
in an online condition. The "B" line is not connected to a trunk unit when configured for start
mode operation.
Start modes (minimum vintage BA)
In a start mode (sometimes called the Code-a-Phone or start-stop mode), playback of a
message does not begin until a start pulse is received by the announcement machine. Two
subcategories of the start mode exist: pulse start and level start.
