STM-1
An STM-1 (Synchronous Transport Module, level 1), is the basic unit of framing in SDH and operates at 155.520 megabits per second (Mbit/s), and in terms of high-level functionality, frame size, and bit-rate is equivalent to an OC-3c in SONET.
An STM-1 optical interface is the smallest interface available from Southern Cross.

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.

General characteristics
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. |
|
|
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
|
|
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. |

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

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.

Configurations
PROTECTED
A Protected configuration provides a single traffic circuit between two specific access points, inclusive of the in-built self-restoration capabilities provided by the network. The network protection mechanism is compliant with ITU-T G.841. A Southern Cross Protected circuit is typically provided using technologies such as SNC-P protection, Optical Switching and/or Mesh networking technologies.
2 DROP
A 2 Drop configuration provides two non-overlapping traffic circuits, each between two specific access points, configured in a ring around the network. Access points for the two circuits can be via the same or seperate cable stations in the source and/or destination country. The traffic circuits are neither protected or restored in the event of failure.
3 DROP
A 3 Drop configuration provides three non-overlapping traffic circuits, each between two specific access points, configured in a ring around the network. Access points for any two circuits can be via the same or seperate cable stations in the source and/or destination country. The traffic circuits are neither protected or restored in the event of failure.
4 DROP
A 4 Drop configuration provides four non-overlapping traffic circuits, each between two specific access points, configured in a ring around the network. Access points for any two circuits can be via the same or seperate cable stations in the source and/or destination country. The traffic circuits are neither protected or restored in the event of failure.
UNPROTECTED
An unprotected configuration provides a single linear traffic circuit, between two specific access points, configured around the network. The service is accessed vi a single access point in each of the terminal countries. The traffic circuit is neither protected or restored in the event of failure.
DROP RESTORED
An N-Drop Restored configuration mirrors its N-Drop counterpart and provides N (2,3 or 4) non-overlapping traffic circuits, each between two specific access points, configured in a ring around the network. Access points for any two circuits can be via the same or seperate cable stations in the source and/or destination country.
However, two of the circuits (elected at time of activation) are configured to be restorable in the event of failure.
