8 port MIX-enabled multichannel T1/E1 with CSU/DSU PA-MCX-8TE1
This family of multipurpose MIX-enabled port adapters comprises three membersâ€”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.
The MIX-enabled T1/E1 port adapter enhances the multiservice solutions enabled by the enhanced digital voice adapters available on the Cisco 7200 VXR series of routers. By using the TDM capabilities of the Cisco 7200 VXR, the MIX-enabled T1/E1 port adapter can maximize the use of digital-signal-processor (DSP) resources on the enhanced digital voice adapters. The MIX-enabled T1/E1 port adapter enables the use of the DSP resource pool on the enhanced digital voice adapters for high- and medium-complexity coder/decoder (codec) voice calls. The concept of sharing the DSP resources across the TDM bus on the Cisco 7200 VXR platform is called DSP farming. With the DSP farm capability, a total of 20 T1s or 18 E1s of voice can be terminated on a Cisco 7206 VXR Series Router, providing a highly cost-effective solution.
