Cobalt Digital COMPASS 9220 Bidirectional ASI_MPTS Gateway - Manual (Page 21)

If the connected input bit rate is higher than the rate entered in the Bit
Rate field, the ASI port will attempt to remove NULL packets from the
input in order to achieve the desired value. PCR packets will be
re-stamped as required. If there are not enough NULL packets to be
deleted, packets will be dropped, and an alarm will be raised. This alarm
will be indicated in the Dashboard™ Card State field, in the front Status
LED, and in the ASI Statistics page.
o Automatic: If this mode is selected, the Bit Rate field disappears. The ASI
output will exactly match the rate of the connected input. However, if the
connected input has no data, or if the ASI port is not connected to any input, there
will be no output, and any connected downstream ASI device will indicate loss of
sync. The ASI Statistics page will indicate this state. Note that an alarm will only
be raised if there is an input connected to the ASI output.
•
Bit Rate: This field is only available if the ASI Rate mode is set to Manual. Enter the
desired ASI output bit rate here, in bits/second. The minimum value is 64,000 and the
maximum value is 213,000,000.
Once the port is configured, click on the Apply button, and the configuration takes effect. If
there are any errors, they will be reported in the area on top of the Apply button. Two types of
errors can be reported:
1. Errors related to the port configuration itself. The only error of this kind applies to ASI
outputs; the 9220 requires individual output transport stream licenses, and if none are
available, the port configuration will fail. Contact Cobalt Digital Inc. to obtain additional
licenses.
2. Errors related to the connection, if you are configuring one. These are described in the
Connections section.
As ports are configured, they become visible in the Active ASI Ports table. An example is
depicted below:
The columns of the table are as follows:
•
Mode: Indicates the port mode (Transmit or Receive).
•
Status: Indicates the port status. It can contain the following values:
