7.4.4 ASI Output Module
For ASI modules, the Port Settings tab is shown below:
Figure 7.39 - Port Settings Tab for ASI Modules
An ASI output module can output up to four separate MPTSs. The ASI output configuration is
similar to that of an IP MPTS output, except for a different
Port Settings tab.
The following ASI parameters are available:
Rate [Mbps] Total ASI output rate - the stream will be stuffed with NULL packets to
maintain the correct fixed bit rate.
Packet Size TS packet size (188 or 204)
Byte Mode Byte mode specifies how the TS data is transported over the ASI link:
Burst Mode – In burst mode, all TS-data-bytes are sent without any idle
symbols in between. Maximum data rate in burst mode is 213 Mbps per
port.
Spread Mode – In spread mode, the ASI specification requires at least
one idle byte between each data-byte, and each packet start indicator
(0x47) is preceded with at least two idle bytes. The ASI output stream in
spread mode guarantees that each data-byte is preceded with two idle
symbols. This effectively reduces the maximum data rate to 1/3 of the
maximum ASI output rate, i.e., (213/3) Mbps. If higher rates are
required, use burst mode.

Please refer to the Terrestrial Solution Configuration Guide for more information
7.4.4.2 ASI Cloned Output
The ASI cloned Output mode allows you to set any available output port as a “monitor” port for
an active one. Service configuration that is performed to the active port is then output on both
physical ports.
In order to configure this, on the active port you can select the Port Settings tab. Here you
have the option to choose an inactive port in which to be used as a monitor port. Once this
