Operation 671
Multi-Channel RAN modes
In Multi-Channel RAN, multiple RAN channels can be configured within one
RAN trunk route. In a Multi-Channel RAN route, each trunk has its own
dedicated RAN channel on a physical 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 arenot 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.
