Product Overview
This data sheet details the features of the new modular OC-48c/STM-16 ATM SPA for Cisco 7600 Series routers.
The Cisco 1-Port OC-48c/STM-16 ATM SPA, in conjunction with other SPAs implementing various types of
network technologies, allows users to flexibly build cost-effective routing solutions that focus on point-of-presence
(POP) and service provider core applications targeted for all telcos and Internet service providers (ISPs), for
worldwide use. This SPA includes a comprehensive ATM feature set, including per-virtual circuit and per-virtual
path traffic shaping; ATM service classes, including constant bit rate (CBR), non-real time variable bit rate (VBR-
nrt), real-time variable bit rate (VBR-rt), unspecified bit rate (UBR), Layer 3 QoS, a high-performance
segmentation-and-reassembly (SAR) architecture, and support for a large number of ATM virtual connections. All
these features are based on industry specifications and standards.
