Tele-45 layer 2+ managed Gigabit Ethernet switches are positioned as a Carrier Ethernet access switch solution. They are equipped with 24 100Base-FX / 1000Base-X dual-speed optical ports based on SFP and 4 uplink ports 10G Base-X SFP + or 1000Base-X SFP. The Tele-45 offers the best flexibility and scalability for operators and service providers to deploy their Metro Ethernet networks. Targeted specifically at Metro Ethernet implementation, the Tele-45 specifications fully comply with the Carrier Ethernet attributes proposed by the Metro Ethernet Forum. The switches comply with the MEF 9 standard to support E-Line / E-Access services and the MEF 14 standard to allow configuration of the bandwidth profile to deliver Service Level Agreement (SLA) with end-to-end performance characteristics Predictable. The Tele-45 also supports advanced OAM management to quickly detect and recover network incidents in real-time
