Services

HSCSD Services:

HSCSD services have two distinguishing features:

  • Symmetric / Asymmetric: Symmetric connections provide identical throughput rates in the uplink and downlink directions. Asymmetric connections have a greater throughput rate in the downlink direction. Note that HSCSD does not provide for higher throughput rates in the uplink rather than in the downlink direction .
  • Transparent / Non-Transparent: Transparent data services do not deploy extra measures for error recognition or correction while non-transparent data services use the Radio Link Protocol (RLP) to carry out these functions.
