scaling up to up to 240 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

• 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.
