Cisco 7304 6-Port Clear Channel
E3 Line Card with Digital Service Unit.



Major service provider and enterprise customers have requested a cost-effective and time-to-market solution for E3 interfaces on the Cisco 7304 platform for network edge aggregation deployments.

It provides customers with 6-port E3 connections in a single interface slot, ideal for providing direct customer IP access or network-to-network connections where copper E3 is the only service to a remote point of presence (POP).
