For ASI modules, the
Port Settings
tab is shown below:
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.

8.4.4.2
ASI Cloned Output
The ASI cloned Out
put 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 setting is applied, the inactive port will
not be able to be configured in the GUI, but will be a duplication of the active port.
