Figure 4 Typical Deployment: Small Branch Data and IP Phones
Small Branch Data and IP Phones
TheCiscoEtherSwitchNetworkModulecombined withanalogor digitalvoicemodules fortheCisco 2600/3600/3700series
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 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 in-line power.

Data Communications Networks (DCN)
Another unique application of the Cisco EtherSwitch NM with Cisco 2600/3600 routers is in a Cisco DCN (Data
Communications Network) operations and facilitiesmanagement solution. The Cisco DCN solution can be deployed using
Cisco routers and Catalyst switches and delivers an out-of-band network used by service providers and large enterprises for
managing their primary network. By integrating the routing and switching functionality into one form factor, service
