1G Giganet

 

Ethernet is an increasingly important service for many of todays carriers and service providers. Southern Cross has a number of Ethernet Private Line (EPL) products (SX Giganet), providing the security, privacy and dedicated bandwidth connectivity of a private line service on Soutehrn Cross' robust ring based network architecture, with the flexibility and scalability of Ethernet interfacing.

Southern Cross offers Ethernet connectivity starting at a 1 Gigabit interface, and uses Generic Framing Protocol (GFP) to transport the Ethernet frames over the underlying SDH/OTN network. This allows the inherent and superior network restorative features of SDH/OTN to be applied to your Ethernet circuits, in a similar fashion to our SDH/OTN portfolio.

Note: Protected Ethernet configurations refer to the SDH/OTN network side protection. Port (MSP) protection is not available on native Ethernet interfaces.

Southern Cross Giganet EPL services are provided using Generic Framing Protocol (GFP) which allows asynchronous (octet aligned, variable length) payloads such as Ethernet to be carried over octet-synchronous networks.

 

 Ethernet Throughtput Estimates

 As part of the GFP procedure the Ethernet frames (save the 'pre-amble' and 'frame delimiter') are encapsulated within a GFP frame, before being transported as part of the SDH/OTN payload. Actual data 'throughput' is therefore impacted by the efficiency and attributes of the client Ethernet network, particularly frame size.

The table indicates the estimated maximum throughput that will be achieved via a Giganet circuit based on the client Ethernet frame size selection, and is calculated in accordance with ITU-T Recommendation G.7041. However, as actual throughput is impacted by a number of client side settings (such as Ethernet frame check sequence), these should be used as a guide only.

 

Note: Giganet (1GbE) and Giganet 10L (10G LAN-PHY) services require Ethernet interfaces on connecting backhaul. Giganet 10W (WAN-PHY) services require and SDH interface on connecting backhaul.

2.5 Gigawave

 

Gigawave is an important service for many of todays carriers and service providers who require transparency of SDH/SONET overhead section signalling information on their services within Australasia and the USA.

Southern Cross offers Transparent SDH line solutions at both the 2.5 Gigabit and 10 Gigabit  interface level. Southern Cross uses virtual concatenation and/or OTN (Optical Transport Network) functionality to transport the SDH/SONET line signal transparently over our robust backbone network. This allows the inherent and superior network restorative features of SDH/OTN to be applied to your SDH circuits, while maintaining the inherent featrures of transparent carriage of a customers SDH/SONET signals.

What is Transparent SDH?

Traditional SDH/SONET carriage terminates the section/RS and line/MS layer information, and hence associated in-band OA&M channels at the network boundaries.

Southern Cross Gigawave services employ virtual concantenation and/or OTN functionality to transport SDH/SONET line signals transparently over the network.

In the case of the 2.5G Gigawave service the client signal is split into 17 STS-3c/VC-4 containers over the network, to be re-assembled and handed back as an OC-48/STM-16 signal.

General characteristics  & Features

  • Structure - Rec G.707 SDH
  • Framing - Rec G.707 SDH / G.709 OTN
  • Network Transmission quality - Rec G.826

  • Operating Wavelength range - 1270-1360 nm

 

SDH Mapping: Visibility of the SONET/SDH Section/RS bytes on the client signal is required. The 2.5G Gigawave service is mapped within the Southern Cross SDH network as a VC-4-17v.

Backhaul: Gigawave service require relevant SDH/SONET interfaces on connecting backhaul.

Fault Monitoring: While Southern Cross proactively monitors its network equipment, and has non-intrusive visibility of the B1 byte of the SONET/SDH section/RS information, transparent services by definition do not provide Southern Cross with detailed SDH monitoring capability.

Fault Monitoring is therefore dependent on the customer having adequate SDH/SONET fault monitoring capability to allow notification to Southern Cross in the event of downstream fault conditions.

Timing: As the client signal is tranported transparently across the Southern Cross network, the Southern Cross network interface cannot be used as a timing source.

The client signal and associated client equipment may be able to be used as a timing source. However, this is dependent on the functionality and configuration of the client side equipment, and is not guaranteed by Southern Cross.

10G OTN

 

OTN is an optical transport standard developed by the ITU-T and first standardized in 1998. It is also known as ITU G.709 or"digital wrapper." As part of OTN, the ITU has defined payload encapsulation, OAM overhead, forward error correction (FEC), and multiplexing hierarchy parameters. The result is a transport standard that includes the benefits of SDH but with improvements for transporting data payloads.

Southern Cross' 10G service is presented via an OTN OTU-2 interface. OTN services are not currently available in Fiji.
