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
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.
