Freq - frequency in KHz

FEC - error correcting coder mode

SR - symbol rate

BR - user bit rate (calculated based on SR and FEC)

TX - transmit mode (ON, OFF, PURE, BALANCE, /INV, /TLC); spectrum inversion

switching on and TLC are also displayed here

SetLvl - transmit level set by the user

OutLvl - current transmit level, with TLC correction

Max - maximum permitted level for TLC

Min - minimum permitted level for TLC

10M - switching 10 MHz signal on

24V - switching BUC power supply on

Rate/Bps - current traffic rate in transmit mode

If DVB-S2 mode is active the following section will be added to the statistics:

------------------------------------------------------------------------------

Mode: ACM-LF Modulation: 8PSK FEC: 5/6

Mode modulator operation mode

Modulation type of modulation

FEC Forward Error Correction mode of LDPC coder

Pilots Pilot-signal mode

Roloff type of output filter

Furthermore, statistics show information on four priority packet queues. Traffic from IP-router is fed to these

queues. The first queue to be able to transmit a packet is the HIGH queue, and if it is not empty – then MED

queue, and if it is empty – then the LOW queue. The fourth service queue CTRL has the highest priority and

purposed for: frame plans service traffic, routing control, statistics, etc. In the TDMA mode, prioritization is

implemented on the packet fragment level, while in the SCPC mode - on the whole packet level.

For each of the queues, shown in the display is the number of packets and bytes that have passed through it, the

queue length in bytes (this permits to judge on the overload and delays), the queue depth, as well as the number

of packets lost from the queue due to serious overload with traffic. The depth of every queue could be defined by

command:

queues 20-800 20-400 20-200 - TX queues length in packets (LOW MED HIGH)

where every value is maximal depth of queue in packets.

Counters can be cleared using the “clear counters modulator” command.

2.8 Controlled SCPC

Controlled SCPC (CSCPC) mode allows creating “star” topology network based on SCPC channels. Central station of

such network called “Master” broadcasts a carrier towards peripheral stations (Slaves). All slaves receive this

carrier. With the help of special service information transmitted via broadcast channel master can allow one of the

slaves to start transmitting the carrier with specified bandwidth and level.
