Synchronization of time and frequency has always been crucial to cable networks since the development of data over cable service interface specification (DOCSISŪ), the first and still current cable-modem interface standard. Historically the crucial synchronization was contained within a single CMTS shelf and thus a proprietary implementation. Today, that is all changing.
Broadband cable operators are in a fierce market battle to innovate their competitive service platform for future success. They are rapidly escalating current services to satisfy hungry consumer demand for high-speed, high-bandwidth networks, and are looking to build secure, fast and cost-effective, state-of-the-art network infrastructures to run these new applications.
To accomplish this, the move is on to break apart the all-in-one-box architecture of CMTS and craft an advanced DOCSIS platform to allow sharing of network components across multiple services while leveraging economies of scale. This next platform, named Modular CMTS (M-CMTS), converges DOCSIS and Video on Demand (VoD) networks.
The synchronization interface, named DOCSIS Timing Interface (DTI), ensures that the M-CMTS core, Edge QAMs and upstream burst receivers are synchronized to support the existing DOCSIS requirements for frequency and timestamps that existed in the traditional CMTS. DTI lays a foundation for the existing and future network architectures to converge voice, data and video reliably and economically.
Symmetricom is the only company that offers a CableLabs qualified M-CMTS DOCSIS DTI Server, the TimeCreator 1000. Combining the TimeCreator 1000 DTI Server with a network of M-CMTS devices with embedded DTI Clients, Symmetricom provides cable operators who want advanced next generation services with timing and synchronization that:
- Reduces operating costs
- Is reliable and economical
- Increases network scalability and flexibility
