DCC: Data Communications Channel
Data Communications Channel (DCC) is the inband data communication channel in SONET/SDH communication. Each SONET/SDH frame includes two Data Communication Channels (DCC) called Section DCC and Line DCC for transporting management messages between NEs and between NEs and Management systems. DCC enables service providers’Operation Support Systems (OSS) to manage SONET/SDH Network Elements (NE) without the need for an expensive out-of-band data communication network.
