Circuit Core Intermediary Course (CCIC) Description

CCIC covers the intermediary level knowledge of Circuit Core in the Mobile Network and it is made up of three main modules: System Architecture, Interfaces & Protocols and Traffic Cases.

Circuit Core Network is that part of the mobile telecom network which handles the voice, SMS, USSD services.
