Basın Bülteni Allied Telesis Đleri Düzey QoS özelliklere sahip Layer 3+ Fast Ethernet Switch Ürününü Duyurdu 1U yüksekliğe sahip AT-x900-48FS, performans, güvenilirlik ve esneklik özelliklerini bir arada sunuyor. Chiasso, Switzerland. 19 July 2007 – Allied Telesis, a global provider of secure IP/Ethernet access solutions and an industry leader in the deployment of IP Triple Play networks over copper and fiber access infrastructures, today announced the launch of the AT-x900-48FS, a new advanced Layer 3 switch. The high-density device with a low cost per port is ideal for both Fiber To The Home (FTTH) and Fiber To The Desk (FTTD) applications and comes with an unusually rich feature set, including 48 100FX SFP ports and 4 1000FX SFP uplinks. With a next generation switching core for wirespeed IPv4 and IPv6 routing, the AT-x90048FS is supplied with several functions that ensure service and resilience are paramount. These range from AC or DC hot swappable power supplies and bestin-class Quality of Service (QoS) to a robust hardware design with extended operating temperatures of up to 50°C (122°F). Policy-based Quality of Service Feature Set Allied Telesis’ new AT-x900-48FS is delivered with extensive QoS features operating at wirespeed. Along with twin-rate three-level metering, these include flow-based traffic management with full classification, prioritization, traffic shaping and minimum/maximum bandwidth profiles. The AT-x900-48FS is ideal for Network Service Providers (NSPs) delivering premium voice, video and data services, as well as for enterprise customers wanting to guarantee the performance of their business-critical applications and maximize uptime. Reliability and Low Space Requirement With front-to-back cooling, Allied Telesis’ powerful new AT-x900-48FS switch is only one rack unit high, making it perfect for demanding, high-density environments where space is at a premium. Further space savings are provided by the dual hot swappable power supplies, which eliminate the need for an external redundant power supply. With support for Ethernet Protected Switched Ring (EPSR), the device provides rapid failover in ring-based network topologies. Its tolerance for operating temperatures of up to 50°C (122°F) enable it to continue delivering exceptional performance, whether it is installed in a central office or in a roadside cabinet. Future-proof Performance With wirespeed switching on all ports, the AT-x900-48FS switch features four hot swappable Gigabit Ethernet uplink ports that can be aggregated to deliver 4Gbps of bandwidth. As it can support any combination of Gigabit copper and short and long-haul fiber SFP modules, it is flexible enough to adapt to companies’ and NSPs’ changing needs over time. It also offers IPv6 routing along with a choice of SFP interfaces to ensure a long lifecycle and low total cost of ownership. With support for up to 4k VLANs and VLAN double tagging, the AT-x900-48FS enables NSPs and enterprise network engineers to maximize the number of customers or users per switch. “Our new AT-x900-48FS delivers power and intelligence to the network edge while being robust and flexible enough for a wide range of applications and connectivity needs,” said Melvyn Wray, Allied Telesis’ Senior Vice- President of Marketing in EMEA. “Whether for security and budgetconscious companies and government departments, or NSPs delivering Triple Play content, its reliability and QoS features make it a perfect fit for all FTTH and FTTD needs.” By-directional Fiber To support the AT-x900-48FS, Allied Telesis is also launching the AT-SPFXBDLC-13 and AT-SPFXBD-LC-15 100Mbps Bi-Directional SFP modules with Transmit=1310nm and Receive =1550nm (and visa versa). Up to 48 of these optical modules can be installed into the switch, providing ISPs with a linear payas-you-grow upgrade path, whilst allowing single fiber deployment on each port of the switch. Allied Telesis already deliver a wide range of single Bi-Directional fiber based intelligent Multiservice Gateways (iMGs) for Triple Play (VoIP, video and data) installations at the remote end of the fiber.
