Sencore SMD989

The SMD-989 is a versatile DVB-S/S2/S2X/TurboPSK modulator platform capable of one or two channels of modulation per rack unit. The SMD-989 comes standard with IP and ASI inputs to offer flexibility for future changes in network architecture or sourcing content from two different interfaces. The SMD also supports advanced DVB-S2 features such as 16APSK and 32APSK modulation as well as the carriage of multiple streams on a single RF carrier. It also supports the advanced modulator coding scheme turbo PSK and S2X.

Installation and configuration

Creation

SNMP Main Connection

This connector uses a Simple Network Management Protocol (SNMP) connection and requires the following input during element creation:

SNMP CONNECTION:

  • IP address/host: The polling IP of the device.

SNMP Settings:

  • IP port: The IP port of the device.
  • Get community string: The community string used when reading values from the device, by default public.
  • Set community string: The community string used when setting values on the device, by default private.

Usage

System

This page contains system info parameters, including:

  • Unit 10 MHz Reference Clock: Indicates whether the system is using an external or internal 10 Mhz reference clock.
  • Unit 10 MHz External Reference Clock Error: Signals whether an error was encountered with the reference clock (possible values: OK or Fail).
  • Unit Mute on Settings Change: If this is Enabled, the connector automatically mutes the output(s) on a modulation or output setting change. Output(s) are muted only on the bay where the change occurred. If this is Disabled, each output mute setting retains its configured value on a modulation or output setting change.

The page also contains page buttons to the Network Settings, Clone Settings and License Settings subpages.

Network Settings subpage

This subpage contains the following tables:

  • MPEG IP Table: Displays the connector to use as Default Gateway (Connector 1 or Connector 2), and allows you to enable or disable the ICMP Response.

    • Subnet Mask: The subnet mask of the mpeg NIC.
    • Gateway: The gateway of the mpeg NIC.
    • MAC: The MAC address of the mpeg NIC.
    • Link Speed: The link speed in Mbps of the mpeg NIC.
    • Link Status: The link status of the mpeg NIC (Down, Half Duplex or Full Duplex).
    • Rx Rate: The aggregated received bitrate in Mbps.

Clone Settings subpage

This subpage contains the following parameters:

  • Cloning: Allows you to enable or disable the clone settings.

  • Bay Assignment: The licensing bay assignment (Bay 1, Bay 2 or Bay 1 / Bay 2).

Input

This page contains the following information parameters:

  • Primary Input: The primary input source for the stream. Refer to the Label values from the Input Table (see below).
  • Backup Input: The backup input source for the stream. Refer to the Label values from the Input Table (see below). However, note that input failover is not supported when the DVB-S2 multi-stream modes are used.
  • Failover Condition: The condition that triggers failover of the stream input from the primary input source to the backup input source. However, note that input failover is not supported when the DVB-S2 multi-stream modes are used.
  • PRBS Status: Allows you to enable or disable PRBS (pseudo-random binary sequence) as the modulator input.
  • Restore Condition: Condition that triggers the stream input to switch back from the backup input source to the primary input source. However, note that input failover is not supported when the DVB-S2 multi-stream modes are used.

The possible values of the Failover Condition parameter depend on the value of the Restore Condition parameter, and vice versa.

  • If the value of the Restore Condition parameter is not Manual Only, the Failover Condition parameter can be set to anything except Manual Only.
  • If the value of the Failover Condition parameter is Manual Only, the only valid value of the Restore Condition parameter is Manual Only.
  • If the value of the Restore Condition parameter is On Primary TS Restored or On Backup TS Loss, the only valid value for the Failover Condition parameter is On Primary TS Loss.
  • Similarly, if the value of the Restore Condition parameter is On Primary TS Analysis Restored or On Backup TS Analysis Failure, the only valid value for the Failover Condition parameter is On Primary TS Analysis Failure.
  • If the value of the Failover Condition parameter is On Primary TS Loss, then the valid values of the Restore Condition parameter are On Primary TS Restored and On Backup TS Loss.
  • Similarly, if the value of the Failover Condition parameter is On Primary TS Analysis Failure, then the valid values of the Restore Condition parameter are On Primary TS Analysis Restored or On Backup TS Analysis Failure.

The page also displays the Input Table, which includes the following parameters:

  • Label: Label of the input.
  • Bitrate: The calculated bit rate of the stream in Mbps.
  • Status: Allows you to determine whether or not the input is enabled.

Finally, the page also contains a page button to the IP Settings subpage.
