Data Sheet

Small Branch Data and IP Phones

The Cisco EtherSwitch Network Module combined with analog or digital voice modules for the

Cisco 2600, 2800, 3600, 3700, and 3800 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
