Small Branch Data Only
A Cisco EtherSwitch Network Module in a branch data deployment provides the flexibility of integrated routing and
switching functions in one unit for low port densities. This deployment provides high-speed connections between
individual desktops, servers, and other network resources in a single unit for Layer 2 and allows WAN connection at
Layer 3 through the router. The Cisco EtherSwitch NM and Cisco 2800 router also provide an ideal solution for Cisco
2505, 2507, and 2516 users whose requirements have expanded beyond the existing Cisco 2500 Router/hub
capabilities.

Small Branch Data and IP Phones
The Cisco EtherSwitch Network Module combined with analog or digital voice modules for the Cisco Integrated
Services Routers provide a small branch office infrastructure for IP Telephony deployments. This solution can be
combined with Cisco CallManager IP Telephony and the Cisco IOS Survivable Remote Site Telephony (SRS
Telephony) solution. SRS Telephony runs on the local branch office router allowing it to automatically detect a failure in
the network, and initiates a process to intelligently auto-configure the router to provide call-processing backup
redundancy for the IP phones in that office.
The Cisco EtherSwitch NM with the external power chassis provides IP Phone power and phone discovery for Cisco IP
phones. In addition, the Cisco EtherSwitch NM supports automatic VLAN configuration for IP Phones. The auxiliary
VLAN feature allows network administrators to segment phones into separate logical networks even though the data
and voice infrastructures are physically the same. The phone discovery allows the EtherSwitch NM-16ESW-PWR to
automatically detect the presence of an IP phone and supplies Cisco pre-standard power over Ethernet

For 802.3af power over Ethernet support one of the newer EtherSwitch Service Modules (NME-16ES-1G-P, NME-23ES-1G-P, or
NME-XD-48ES-2S-P) or one of the EtherSwitch HWICs (HWIC-4ESW-POE or HWIC-D-9ESW-POE) are recommended.
