(default: 221)
Station modules are assigned
starting at the top (channel 2) of
the available media bay module
DS30 channels.
Exception: DSM 16 or DSM 32
used for Companion. In this
case, DSM 32 must be set to
channel 6. DSM 16 can be
installed in both channels 6 and
7. If channel 7 is not available
you cannot use a DSM32.
Lines start at 61 on
DS30 channel 7
Trunk modules are assigned
starting with the last available
media bay module DS30
channel (channel 6 or 7,
depending on the DS30
channel split in effect).
Exception: a 4X16 module
cannot be assigned to the last
channel.
3/5 channel split
* Channel 7 is not available to any module if your system has been
configured with a 3/5 DS30 channel split
Modules that require two DS30 channels, such as the DSM32 and
the 4X16, must be assigned to channels higher than 6, to allow all
their channels to be active.
Companion: Only a maximum of 16 Companion base stations
(30 handsets) can be registered on a system configured with a
3/5 split.
