Interoperability between Satellite modems

Close

Interfacing satellite modulators and demodulators to user equipment can be complicated.

EIA530, LVDS, HSSI and ASI satellite modem interfaces are serial in nature and can support flexible data rates i.e. 1bps increments on the satellite modem. In contrast G.703/coax satellite modems only support fixed "Telco" rates such as T1 1.544Mbps, E1 2Mbps, E2 8Mbps, E3 34Mbps, DS3 45Mbps and STS-1 52Mbps.

  • Interfacing EIA530/TTL/RS422 satellite modems - standard low to medium speed modem interface for data applications, with modems often supporting flexible data rates, with 1bps granularity up to 20Mbps, including asymmetric operation (different transmit and receive rates)
  • Interfacing LVDS satellite modems - modern high speed modem interfaces for data applications, with modems often supporting flexible data rates, with 1bps granularity up to 52Mbps, including asymmetric operation (different transmit and receive rates)
  • Interfacing HSSI/ECL satellite modems - traditional high speed modem interfaces for data applications, with modems often supporting flexible data rates, with 1bps granularity up to 110Mbps, including asymmetric operation (different transmit and receive rates)
  • Interfacing G.703/coax satellite modems - primarily used for voice trunks and broadcast backbones, with modems supporting fixed "Telco" rates such as T1, E1, E2, E3, DS3, STS-1
  • Interfacing ASI satellite modems - primarily used for the broadcast and distribution of broadcast quality video, with modems often supporting flexible data rates, with 1bps granularity up to 216Mbps, including asymmetric operation (different transmit and receive rates)
