Remote MACPHY systems –
Multi-gigabit solution for coaxial networks
The core of our solutions for signal transmission are our Remote-MACPHY systems compatible up to DOCSIS 3.1. They provide an enormous increase in power of coaxial networks, allowing flexible configuration of the architecture by virtue of the Distributed CCAP approach.
When equipped with Remote-MACPHY, all key functions are no longer located in the headend, but directly in the access node, that means in a highly integrated platform. Our solutions can be adapted precisely to the customer‘s requirements with regards to the spectrum of up to 1218 MHz, data rates, channel assignments and the number of users. Apart from that they are also scalable to future applications. Once implemented, your devices can be controlled according to your individual requirements – via a user-friendly web interface, SNMP or locally on site.
How it works
The Distributed-CCAP-Node can replace existing analogue-optical nodes, because an analogue Fibre-Node is integrated for reconversion of TV signals (RF-Overlay) into electrical signals. The Remote-MACPHY node supports all major DOCSIS standards and can be operated with classic central CMTS units as well as with Remote-PHY in the same network. Between the CCAP nodes and the headend station, digital-optical or alternatively electrical 10G connections can be used for the IP / Internet signals.
With fully digital control, where the TV signals are also fed to the node via the 10G uplink in the form of IP data streams (MPTS or SPTS), the CCAP node takes over the generation of the entire RF spectrum for TV, radio, Internet and telephony:
The proportion of the analogue transmission path is minimised, thus maximising the signal-to-noise ratio of the signals. The higher signal quality enables higher QAM modulations in the networks, which ultimately enable significantly higher transmission speeds for the user.
What are the advantages? Compelling!
- Fully developed system technology, field-proven a thousand times
- Additional services
- Higher return channel bandwidths
- Future-proof
- Simple and space-saving solution in the central headend
- Short implementation times ensure timely switch-over or quick network extension
- Optimum use of the bandwidth – the network becomes a multi-gigabit capable network through modern DOCSIS 3.1 technology
- Low investment costs per user
And what about flexibility? High!
- Various migration scenarios while maintaining the current TV provision via an HFC network
- Continued use of existing coaxial or HFC infrastructures
- For a stepwise network upgrade, temporary coexistence with centralized headend equipment is possible without problems
- High scalability, extension and adaptation to new customer requirements is possible
- Flexible and manufacturer-independent selection of switch and OLT systems in the central headend
And the running costs? Low!
- Cost-efficient software solutions
- No running annual hardware licence costs
- Transparent, full cost check for the operator
- Average profit per customer is high due to low investment costs
- Lower implementation costs
- Lower maintenance costs through PNM support (Proactive Network Maintenance)
