Property Description
is a power line channel that uses the Enhanced LonTalk ® Proxy
Protocol to transmit network messages from the SmartServer to
the devices attached to the channel. For more information on
the Enhanced LonTalk Proxy Protocol and power line
repeating, see the i.LON SmartServer Power Line Repeating
Network Management Guide.
The transceiver ID of the channel. To create a new channel with
the Set function, you must include this property. This property
may be one of the following values:

CUSTOM
The interval (in milliseconds) network messages wait for
confirmation before being re-sent over the network. The default
value is TT_96 for FT-10 channels and TT_512 for PL
channels.
The default interval is calculated based on the network topology,
specifically the transmission time for each channel that the
message must cross. By default, the transmission time for each
channel is determined by its type.
The number of times a network message is re-sent when no
confirmation is received. The default value is 3 for FT-10
channels, and it is 5 for PL-20 channels.
The default retry count, which can range from 0 to 15 attempts,
is calculated based on network topology. Typically, the default
retry count is set to 3 attempts; however, if a message must pass
through certain channel types, the default may be increased. For
example, if a message must cross a PL-20 channel, the default
retry count would be increased to 5 attempts.
The maximum number of priority slots available on the channel.
Priority slots may be used by the critical devices on a network
that use priority messaging.
With priority messaging, the device with the highest priority
sends its packet before any other devices can send theirs. This
