The Cisco 16-port 10/100 Ethernet Switch Network Module (NM-16ESW) is a high-density ethernet network module that provides line-rate Layer 2 switching across Ethernet ports using Cisco IOS® Catalyst Software. Features such as port autosensing, QoS and VLAN support from 802.1P and 802.1Q standards, and 802.1D Spanning Tree protocols are standard on the EtherSwitch module. The EtherSwitch offers service providers the option to integrate switching and routing in one compact platform to simplify their Operations Support Network. This combination offers ease of configuration, deployment and management while utilizing the powerful characteristics of Cisco routing and Catalyst switching features.

With an optional configuration, DC power can be provided directly from the CO to the etherswitch module and from there inline to Cisco IP Phones and Aironet Access Points and Base Stations. This solution allows for deployment of IP Telephony and wireless LANs throughout the CO without adding an AC power source.
