Broadband Access Networks
Next generation, modern and super fast broadband networks must respond and support to the Open Access model to cater for multiple Retail Internet Service Providers (RSP). This provides the ability for subscribers can connect with any participating RSP of their choice, over one compliant and efficient infrastructure .
For those interested in the technology, wholesale open access is done on layer 2 of the OSI network model. Whereas each RSP has exclusive Layer 3 access to their subscribers and each RSP provides their own Internet Protocol (IP) subscriber management and backhaul/peering facilities. The broadband access network is the physical network layer, which is shared by all participants. It provides and active Bitstream connection as a virtual pathway, connecting each RSP to their own subscribers.
In or near larger cities there is usually no shortage of ISP’s/RSP’s willing to participate, but for rural communities these things are more difficult. A mix of direct buried fibre and/or multi-hop microwave links to the nearest access point is often the only solution. These backhauls can be very expensive to install and maintain. This is where experience counts and a design consultation with field survey will bring up the best concepts.
Sometimes the community need to dig their own trenches and lay their own cabling. Sometimes local resources need to build the masts and facilities for a microwave link. Sometimes there are helpful power companies (or railway operators) with optic fibre on their utility and High Voltage lines, which can be rented. There are often many opportunities that will just have to be discovered and explored for the better of the community. Teletechnique can assist you with bringing together an effective solution for delivering Open Model Broadband Access Networks.
Technologies typically used for Open Access Networks
- GEPON (Ethernet based PON)
- Gigabit Ethernet Passive Fibre Optic Network – based on IEEE 802.3ah
- GPON (ATM and Ethernet based PON)
- Gigabit Passive Fibre Optic Network – based ITU 984
- P2P Metro Ethernet
- Fibre based IEEE 802.3(ab, ag, ah)
- HFC with DOCSIS
- Fibre and Coaxial based (Typically Fibre to each node of 100-200 subs)
- DOCSIS 3.0 is the current deployed standard by Telstra and nbn™ in Australia
- DOCSIS 3.1 has been released by CableLabs and is taking hold of the world market rapidly
- ADSL/VDSL over ULL
- Fibre and Copper Pair based (Typically Fibre to each node of 100-200 subs)
- ADSL2+ is the most widely deployed standard in Australia
- New nbn™ fibre to the node (FTTN) areas will deploy VDSL
Open Access?
Legislation today permits and supports the deployment and use of technologies that provide superfast broadband. One key requirement is simply that each deployment must provide non-discriminatory wholesale access to retail service providers or RSP’s.
RSP’s are engaged directly with the subscribers, whereas the Wholesale Provider is only engaged with the respective RSP’s on the network. The wholesale provide effectively builds and maintain the “in-ground” infrastructure, with an ACCC defined revenue model.
