teleServiceCode

Validations ASN.1 Parent Types

A code which uniquely defines a TeleService.

Group TeleService 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 TeleService group codes can only occur in call independent supplementary service operations.

Derivation:

GSM item TeleServiceCode (GSM 12.05).

The code is derived by taking the MAP encoding (GSM TS 09.02) and translating bits 8-5 into a ‘hex’ character and bits 4-1 into a second ‘hex’ character.

Conditionality:

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