Feature Benefit
Investment Protection
Modular platform which shares interfaces
with Cisco 1700, 2600, 3600
• Network interfaces are field-upgradable to accommodate future technologies
– Additional services can be added on an “integrate as you grow” basis
– Leverages the large existing portfolio of WICs, VICs, NMs and AIMs to reduce sparing,
training, configuration and installation and maintenance costs
