Point-to-Point SDH

Our Point-to-Point SDH services are premium performance, low latency, carrier grade SDH transmission services with interstate and local coverage.

Category:

Suitable for carriers and corporations requiring uncompromising quality, Nextgen Group’s Point-to-Point SDH services are available with dedicated circuit switched bandwidth ranging from 50Mbit/s (VC3) to 9600Mbit/s (VC4-64c). Our core network is built from SDH rings with 50ms protection switching and we offer a range of access circuit protection options.

For efficiencies of scale, we are able to multiplex a number of sub-rate services onto our STM-n interfaces.

Speeds and interfaces

Our network offers a wide range of standard SDH speeds, from 50Mbit/s (VC3) to 9600Mbit/s (VC4-64c), ensuring ability to cater to your current and future needs. We offer increments as fine as 150Mbit/s (VC4) so that customer incremental costs can be managed.

Standard interfaces range from STM-1 to STM-64. Multiple sub-rate circuits can be delivered to a single physical interface to reduce equipment costs and complexity.

24×7 network monitoring

Nextgen Group’s Service Management Centre provides ongoing end-to-end monitoring around the clock for our national network. All SDH elements are actively monitored and our in-line fibre monitoring system can pin-point fibre faults to within a couple of metres across the country. Our technicians are on call to fix the faults any time of the day or night.

Robust network

Nextgen Group’s network is designed and configured for continual operation, with a rebate-backed network commitment of 99.95% per month. Geographic fibre diversity on the east coast is provided by our own fibre. We have electronic and fibre diversity from Melbourne to Perth, with geographic fibre diversity provided through a third party. All of our main switching nodes have on-site spares and we have primary and backup service management centres.

Depending on your business requirements, we can customise access solutions with different levels of redundancy up to and including geographic diversity with dual building entries.

Nextgen Group’s fibre network

Nextgen Group owns and operates the third largest national fibre network in Australia, which is fully redundant on all routes and geographically diverse on the east coast. Our inline fibre monitoring system gives us the ability to pinpoint trouble spots rapidly to within a few metres. The result is a high reliability network with maximum network availability.

Target applications

Nextgen Group’s SDH services are suitable for a wide range of applications:

• Interstate and Local Transmission
• Data Centre Interconnection
• ATM Switch Interconnection
• Channelised Transmission
