Annex C: Bibliography

Specifies the service description and control aspects, including functional capabilities and information flows, of standardised circuit-mode bearer services. Includes the following sections: symbols and abbreviations; circuit-mode 64 kbit/s unrestricted 8 kHz structured bearer service category; circuit-mode 64 kbit/s 8 kHz structured bearer service category usable for speech information transfer; information flow sequences; allocation of functional entities to physical entities. Also gives definitions.
