The AudioCodes Mediant 500L multi-service business router (MSBR) combines WAN access, routing, voice and security in a single device. It is designed for small offices and SMBs, and for the service providers delivering managed data, SIP trunking, hosted PBX and cloud-based services to them. Its multi-core architecture maintains consistent performance across data and voice. The M500L-I8S-AGECSLA is the eight-FXS configuration, the maximum analog port count of the Mediant 500L platform. It suits sites with a larger set of analog phones, fax machines or other analog endpoints moving to IP voice. This Americas configuration offers four WAN paths: - ADSL2+/VDSL2 with vectoring - A 1000Base-T Gigabit Ethernet WAN port - A dual-mode SFP WAN interface - An internal 3G/4G LTE Cat 4 modem covering North American LTE bands B2, B4, B12 and B13 Because these are multiple, redundant WAN options, a site can keep voice and data running over LTE when its primary circuit is unavailable. The unit includes a USB port and Gigabit Ethernet networking. The chassis measures 51 x 296 x 160 mm (H x W x D), weighs 670 g and can sit on a desk or mount in a 19-inch rack.
