bearerServiceCode

Validations ASN.1 Parent Types

A code which uniquely defines a Bearer Service.

Group Bearer Codes, identifiable by the description ‘All’, should only be used where details of the specific services affected are not available from the network.

Note that compound Bearer Service group codes can only occur in conjunction with HSCSD usage or call independent supplementary service operations.

Derivation:

GSM item BearerServiceCode (GSM 12.05).

The code is derived by taking the MAP encoding as specified for BearerServiceCode in TS GSM 09.02 and translating bits 7-4 into a ‘hex’ character and bits 3-1 into a second ‘hex’ character.

Conditionality:

Must be present within group Service Code where the type of service used was a bearer service .  Must not be present when the type of service used was a tele service and, therefore, Teleservice Code is present.
