The Cisco 3600 Series is a family of modular, multiservice access platforms for medium and large-sized offices, along with smaller Internet Service Providers (ISPs). The Cisco 3600 Series has over 70 modular interface options and provides solutions for data, voice video, virtual private networks (VPNs), and multiprotocol data routing. This series protects customers' investment in network technology and combines the functions of several devices into a single, easily managed solution.

The Cisco 3600 Series has been extended to the Cisco 3660 multiservice access platform. The Cisco 3660 provides higher densities, greater performance, and more expansion capabilities. The additional power and performance of the Cisco 3660 platform enables new applications.

The Cisco 3600 series of multiservice platforms has been greatly enhanced with many voice capabilities, such as added support for Voice over Frame relay (VoFR) and Voice over ATM (VoATM-AALS). QSIG is also now supported on all digital interfaces, including T1/E1 and BRI. Other improvements include Off Premise Extension (OPX), VoIP over Frame Relay, and enhanced queueing functionality. Additonally, a feature that works with an upcoming version of Call Manager software makes these products ideal gateways for the PBX and PSTN for IP telephony, which enables applications like call transfers, holds, and conferencing.
