Cisco 4 Port MIX multichannel T1/E1 2048Mbit/s networking card

4 Port MIX Multichannel T1/E1 Port Adapter with CSU/DSU This family of multipurpose MIX-enabled port adapters comprises three members—the PA-MCX-2TE1, PA-MCX-4TE1, and PA-MCX-8TE1. These port adapters come with built-in channel service units/data service units (CSUs/DSUs), and they offer the same feature set, differing only in the number of physical interfaces supported.

The MIX-enabled T1/E1 port adapters provide the ability to integrate voice and data on the same T1/E1 interface without the need for an external time-division multiplexing (TDM) device. With the "drop and insert" capability, DS0-level grooming is supported, thus providing cost-effective WAN access. Ports can be configured as voice, data, or both, depending on the application requirements. Powerful management capabilities are provided with the Cisco Voice Manager 2.0 Web-based user interface for provisioning, configuration, and monitoring functions.
