Bearer service

In telecommunications, Bearer Service or data service is a service that allows transmission of information signals between network interfaces. These services give the subscriber the capacity required to transmit appropriate signals between certain access points, i.e. user network interfaces.[1]

Bearer Services are categorized by three classes of attributes: dominant, secondary, and qualifying.[2] These classes are further categorized by accessing services, interworking requirements, and other general characteristics.

The bearer services contain the following:

  1. Rate adapted sub-rate information like circuit switched asynchronous and synchronous duplex data, 300–9600 bits.
  2. Speech and data swapping during a call, i.e. alternate speech and data.
  3. Modem selection, i.e. selection of 3.1 kHz audio service when inter-working with ISDN.
