Port

for the

 Series

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.

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.
