COS Systems delivers a cloud-based platform built for broadband operators, automating operations from demand generation through provisioning, billing, and field service. Operators run COS Business Engine as the operating core for retail, open access, or hybrid models, and add COS Wholesale Engine as the wholesale layer when several ISPs sell on the network. COS FSM, COS Prospector and COS Marketplace extend the portfolio across field service, door-to-door sales and the subscriber storefront, and COS Fiber Flow extends it with Active Ethernet network operations.
