The Dual Gigabit Ethernet Adapter provides dual 10/100/1000 Mbit/s Ethernet communications links on either copper on fibre media and is available in the following industry standard compliant formfactors :

• PMC
  • Air-coolded PMC adapter with Front Panel I/O (IEEE Std 1386.1-2001)
  • Conduction-Cooled PMC (CCPMC) adapter with backplane I/O (ANSI/VITA 20-2001)
  • Conduction-Cooled PMC adapter with Front Panel I/O (requires modification to host carrier)
• PCI-104 (PCI-104 v2.0)
• PCI (PCI Local Bus Specification Rev. 2.3)

Architecture

The Dual Gigabit Ethernet Adapter uses a custom intelligent ASIC for the control of the Gigabit Ethernet MACs (Media Access Controllers). The ASIC removes protocol processing overhead from the host processor, ensuring a higher nett data throughput.

The ASIC supports two distinctly different operational modes, being : Dual Net and Redundant Link Management Technology (RLMT) modes. In Dual Net mode the adapter provides two independent Gigabit Ethernet network interfaces, useful for maximising I/O connectivity and the available network bandwidth. In RLMT mode the adapter provides a single Gigabit Ethernet network interface, using one of its two channels as the default (primary) network link and the other (secondary) as a standby. In the event of the primary link failing, the ASIC automatically switches to the secondary link without any user intervention.

The ASIC also incorporates Virtual Cable Tester (VCT) technology for advanced cable diagnostics. VCT enables the system to pinpoint the location of cabling issues down to a meter or less, reducing network installation and support costs.

Features

• An advanced ASIC removes protocol processing overhead from the host processor, maximising the net data throughput
• User configurable in either Dual Net or Redundant Link Management (dual redundant) modes of operation
• RLMT implemented in hardware manages unattended and automatic failure recovery of downed links in real time
• Automatic MDI/MDIX crossover at all speeds
• High data transmission rate
• Compliant to IEEE 802.3 (Ethernet), IEEE 802.3u (Fast Ethernet) and IEEE 802.3ab (Gigabit Ethernet)

I/O Media Types

Front Panel versions of the adapter supports all of the following I/O media types :

• 1000BASE-SX : Gigabit Ethernet using multimode fibre media and a 850 nm wavelength, over distances of at least 200 m
• 1000BASE-LX : Gigabit Ethenet using singlemode fibre media and a 1 270 to 1 355 nm wavelength, over distances of at least 2 km
• 1000BASE-T (IEEE 802.3ab) : Gigabit Ethernet using Category 5, 5e or 6 copper cable, over distances of up to 100 m
