  1. Chapter 7 – Signaling and Control Signaling – extension of control information from one network node or user to another over one or more network links Signaling between user and serving node Subscriber device and serving switch Signaling between two network nodes Switch to switch

  2. Chapter 7 – Signaling and Control Signaling domains

  3. Chapter 7 – Signaling and Control Channel Associated Signaling (CAS) or In band Same circuit/path used for signaling and voice/data payload Bandwidth of circuit reserved for signaling Common-channel signaling (CCS) or out of band Separate circuit/path/network used for signaling Full bandwidth can be used for payload

  4. Chapter 7 – Signaling and Control CCS – out of band ITU – Q.931 used between private branch exchanges (PBX) ISDN Private corporate network ITU – Signaling System No. 7 (SS7) Signaling between carrier networks
