Cisco 16- and 36-port EtherSwitch Modules

SINGLE PLATFORM SOLUTION FOR BRANCH OFFICE IP TELEPHONY AND VOICE GATEWAY

As the migration to converged voice/data networks accelerates, enterprises need to deploy a platform that has the ability to immediately or

gradually grow to support a wide range of traditional telephony devices in addition to newer IP telephony solutions. The Cisco 3700 Series

delivers on that need by supporting legacy phone systems through a variety of scalable analog telephony connectivity options starting at two

analog ports and scaling to 16, 32, 48 or 64 analog ports. Digital telephony connectivity is just as scalable with options beginning at 12

channels and scaling up to up to 480 channels. IP telephony solutions are also supported on the Cisco 3700 Series through a powerful set of

features including line powered IP phone connectivity that begins with 16 ports and scales to 36, 52, or 72 ports in a single platform.

The performance-tuning of the Cisco 3700 Series enables customers to apply quality of service, bandwidth optimization and fragmentation

services, along with other advanced call admission control, call control and queuing mechanisms, without sacrificing the expected data

performance needed for future growth. The Cisco 3700 Series offers resilient IP telephony services, including Survivable Remote Site

Telephony (SRST), H.323, SIP and MGCP, and redundant power for the system and IP phones.

With the Cisco 3700 Series, enterprises can deploy this scalable platform to support all of their telephony needs without investing in all

connectivity requirements in the initial deployment. The enhanced service density of the Cisco 3700 allows enterprises the opportunity to

deploy a base level configuration that will scale to the converged telephony needs of that branch when necessary. This modular telephony

format mitigates future technology lockout.

Deployment of IP Telephony infrastructure solutions are facilitated by the following key Cisco 3700 features:

• Optional modular integration of an inline-powered EtherSwitch NM or HDSM, combined with analog and/or digital high-density voice

gateway modules and flexible WAN connectivity for a modular, single-platform IP Telephony infrastructure

• Resilient IP Telephony services, including Survivable Remote Site Telephony (SRST), H.323, SIP and MGCP, and redundant power for

system and IP phones

• Complete Cisco CallManager support for both H.323 and MGCP call control protocols makes the Cisco 3700 the ideal voice gateway

• Integrated Cisco Unity Express for Voice Mail and Auto Attendant services

• Performance-tuned to scale both analog, and digital voice solutions and hybrid solutions

• Modular expandability enables the addition of gateway or phone aggregation ports as needed

• Integrated Time Division Multiplexing (TDM) for full Drop&Insert functionality between all WIC, Network Module and onboard AIM’s

The evolution from traditional TDM voice to IP Telephony has created the requirement that branch offices be equipped to deploy IP Telephony

solutions without the need to replace the branch office access platforms. The Cisco 3700 series fulfills that need by ensuring complete support

for the range of voice gateway densities and IP Telephony features necessary for Enterprises’ evolving branch office infrastructures.
