The Cisco ONS 15310-MA is a carrier-class MSPP that efficiently switches Ethernet and TDM traffic for use in metropolitan and regional optical networks. Its flexibility and scalability allow it to support 1.5-Mbps to 2.5-Gbps TDM, as well as 10/100/1000-Mbps Ethernet interfaces. The Cisco ONS 15310-MA can aggregate traffic at a central office or collect services at the customer premises. At a central office, it can groom traffic from multiple customer-located network elements, such as the Cisco ONS 15310-CL, Cisco Catalyst 3750 Series Switch, or another Cisco ONS 15310-MA for distribution to other networks or handoff to specialized networking devices, such as a Cisco 7600 Series Router, a high-capacity digital cross-connect (DXC), or a Class 5 telephone switch. At the customer premises, the Cisco ONS 15310-MA can collect high-density and highcapacity traffic from medium-sized and large businesses, or from several customers in a multitenant location.
