CBC Conformance Testing and Interoperability
Issues

• Interface 1 Base Station Standards
• Communication with BSC manufacturers is required
• Conformance Testing normally occurs using BSC
  simulators, or Test BSCs or at the Customer Site
• Cost of BSC activation for CBC is questionable,
  as is the quality of some BSC configurations.
• There are some performance issues with BSCs
• We need buy in from the manufacturers to CBC.
• We need better access to standards and testing
  facilities

CBC Conformance Testing and Interoperability
Issues

• Interface 2 Handset / SIM issues
• Need for CBC download support to be standardised
• Storage of CBC profiles of the SIM made standard
  (channels etc)
• Un-Intrusive Receipt of Class 2 Messages as
  standard
• The need for a published list of CBC compliant
  handset / SIM combinations
• Question to Handset manufacturers what sort of
  resources are they willing to commit to
  standardisation of CBC? Will it be a ride along?
