---------- Traffic Shaper parameters

shaper stream 0-500 0-64000 [0-64000] - TS stream CIR(Kbps) [MAXSPEED(Kbps)]

Stream parameter adjustment. Guaranteed bit rate (CIR) and optionally – maximum stream bit rate are set. If

maximum bit rate is not set, stream bit rate will be tantalizingly constrained by CIR. Stream bit rates are

measured in kilobit per second (1024 bit/s). When selecting stream numbers it is better to number them from the

beginning and not to use too large numbers (numbering 100, 200, 300... is undesirable, better numbers are 1, 2,

3 or 2, 4, 6).

shaper delete 0-500 - Delete TS stream

Nulls stream parameters by switching this stream over to TS transparent algorithm.

shaper bandwidth 0-128000 - Composite channel bandwidth (Kbps)

Output bandwidth limit to which TS algorithm will reference to. This is not a tough (monitored) value but a

desirable one – with sharp changes in traffic at the input, the TS output traffic may exceed this value. It is

expedient to first set the TS bandwidth 5% less than the channel bandwidth and then correct it while observing

the network traffic.

shaper slope 1-64 - Shaper algorithm slope factor

Relative non-dimensional coefficient (a multiple) monitoring how TS is adapting (increasing) streams bandwidth.

Value 16 is optimum to begin with, and it can be corrected if necessary.

TS settings and statistics can be observed using ―show shaper‖ command.

1 | 100 0 | 0 0 | 0.0 | 0 0 0 |

5 | 256 384 | 0 0 | 0.0 | 0 0 0 |

Slope - Bandwidth adaptation coefficient.

Bandwidth - Desirable TS output bandwidth.

ModSpeed - modulator traffic rate in kilobits and in per cent of the modulator

maximum possible bandwidth (physical).

ModDelay - Delay on the modulator in seconds (queues length / bit rate).

Strm - Stream number.

CIR.K - Assigned certified information rate.

Max.K - Assigned maximum permissible bit rate.

Spd.bps - Current bit rate at the stream output in bits per second and per cent.

Per cent is calculated with reference to CIR.

Del - Delay on the stream is seconds (queues length / bit rate).

LowSp,... - Bit rates in each queue inside the stream.

Title - Stream name (for CS). Setting is performed only from NMS and

transmitted to the router on the network.

2.10 Satellite Pointing

Satellite routers have built-in tools for pointing the antenna to the satellite. The router

provides actual information about overall input signal level (RF Level), as well as the quality

of the reception of the carrier (Eb/No) from the Hub (or carrier of another station in SCPC

mode) when demodulators locks on such carrier. Such information can be obtained in real

time via HTTP interface, a local console (command line) or as an analog DC signal.

Pointing procedure is common for any method of displaying the level of signal quality:

 Calculate expected elevation and azimuth (corrected accordingly to magnetic

declination). Such calculations can be performed with EASTAR Calculation Tool

available on the Documentation CD or can be downloaded from the Web.

 Direct the antenna toward the satellite. When installing the angle of elevation please

take into account offset angle of parabolic antenna (specified in the description) or

use an elevation scale of antenna.

 Access the information about actual signal level of satellite router with any of

methods described below.
