Media control protocol for ew G3 and 2000 series
01/2012 28/37
States [get only by cyclic attributes]
Valid for device EM only
Description
This attribute is sent to media control together with other cyclic attributes. The first
parameter shows Mute flags since last cycle. "Since last cycle" means that this
parameter does not represent the current mute status but what happened during
last cycle. For instance at the beginning of a cycle there is no RF-Mute. Thus bit 2 is
set to '0'. If a RF-Mute occurs this bit is set to '1'. This bit stays '1' even then when
RF-Mute does not exist anymore when the cyclic attributes are sent out next. This
bit 2 is set to '0' if RF-Mute is not detected for more than a complete cycle. In other
words these bits are set to '1' whenever within a cycle the appropriate mute was
active.
Bit 0 is set to '1' if for more than one complete cycle any kind of mute (TX, RF or RX)
was active. For instance when bit 0 is set to '0' and bit 2 is set to '1' it
means that RF-Mute was detected once since last cycle but it was not permanently
active. When bit 0 is set to '1' and bit 2 is set to '1' it means that RF-Mute was active
for the complete cycle. If the pilot tone is deactivated, the pilot flag will be
processed.
The second parameter shows the Pilot flag since last cycle.
Parameters
Examples
States 3 0<CR>
RF-Mute occurred during last cycle, no pilot signal detected for complete cycle.
States 9 1<CR>
TX-Mute and RX-Mute detected during last cycle, pilot signal detected for complete
cycle.
States 0 2<CR>
no Mute occurred during last cycle, pilot signal changed within last cycle .

Mute flags Bit 0: Mute
Bit 1: TX-Mute
Bit 2: RF-Mute
Bit 3: RX-Mute
– – No
Pilot flags 0: since last cycle no pilot
signal was detected
1: since last cycle a pilot signal
was permanently received
2: since last cycle a pilot signal
was not permanently received,
i. e a change in reception of
pilot signal occurred within
last period
