TAC-900 Multi-Service Access Concentrator

The TAC-900 is a powerful concentrator that can serve as a centralized switching point for an ATM network and offers extended features such as power redundancy, increased management capability, and AC or DC power. It can switch cells between interface modules located within the TAC-900, and is compatible with the TAC-300 to provide a hub for the smaller unit at remote locations. With its higher port count, local services can also be provided at the hub site.
