Introduction
The Cisco IAD2430 is the next generation integrated voice and data services platform for Service
Providers, building on the Cisco IAD2420 series IAD. The Cisco IAD2430 series offers software
functionality such as MGCP SRST used to accelerate the migration from TDM to VoIP cost efficiently.
The Cisco IAD2430 series harnesses the maturity of the Cisco IAD2420 series software and enhances
functionality by providing more capabilities such as denser interfaces (up to 24 FXS or up to 2 voice and
2 data T1s), encryption, and DC power backup while maintaining its 1RU form factor for space saving
service provider managed services deployment.
