description
The transition of private networks to IP standards opens up a plethora of backhaul options. These range from simply replacing traditional TDM-based backhaul with IP-based transmission systems of similar capacity to placing the backhaul in the hands of commercial telecommunications carriers and their low-cost IP service options. The promises of ubiquitous broadband coverage from national broadband networks (NBNs) potentially add even more confusion to this already complex design environment. This paper is based on the recent experiences of ATI in the Australian environment of providing high-capacity broadband backhaul in remote regional areas as well as urban areas. It touches on the important network variables as well as backhaul transmission characteristics in order to provide a set of selection and design guidelines applicable to most network cases, with particular focus on network security and cost.

COMMS CONNECT 2014
NBN Summary
• Most comms sites limited to fixed wireless and satellite
• Low cost • Low voice grade bandwidth • Complex access
COMMS CONNECT 2014
Microwave
• Mature technology • Gbps capacity • User defined availability • Simple deployment • Low cost
COMMS CONNECT 2014
Use NBN
• Wide geographic dispersion of sites • Within NBN footprint • Low capacity requirement • Mature IP design capability
COMMS CONNECT 2014
Use Private Microwave
• Regional coverage requirement • Outside NBN footprint • High capacity requirement • Require simple network architecture • Internally managed and defined availability and security
