  • Page 5: Introduction

    1. Introduction The STM SatLink 1000, 1900, 1901 and 1910 are the indoor units (IDUs) of the STM SatLink VSAT family of DVB-RCS VSATs. They perform several functions: they are satellite modems (at Layer 1); they handle data link layer processing (at Layer 2) for both satellite and LAN communications; and they act as IP routers and DHCP servers (at Layer 3).

    VSAT has been correctly installed and commissioned by the Network Operator, it is convenient to enable rx autostart and tx autostart as described in section 6.5. When rx autostart and tx autostart are set to off (disabled), the STM SatLink VSAT will make one attempt to acquire the forward link when issuing the CLI command .

  • Page 114: Appendix N. Accessing The Forward Link Signalling

    A rough outline of the procedure is as follows: The STM SatLink VSAT tunes to the transport stream of the forward link that it has pre-configured as ”start-up” forward link. There it reads the NIT. The NIT PID value is hard-coded in the SatLink VSAT.
  • Page 115 The STM SatLink VSAT can report the following Receiver State status: Tuning transponder one Tuning transponder two Tuning transponder three Waiting for NIT (transponder one) Waiting for PAT (transponder two) Waiting for PMT (transponder two) Waiting for RMT (transponder two)
