The MIX-Enabled T1/E1 multi-channel port adapter (PA-MCX) provides the ability to integrate legacy voice traffic and data over the same T1 or E1 interface. Using the Multi-service Interchange (MIX) bus of the 7200VXR router platform, the PA-MCX can:
- Provide additional T1/E1 interfaces to voice channels on the Enhanced Digital Voice Port Adapter (PA-VXC-2TE1+), effectively enabling the DSPfarm feature
- Terminate N x DS0 data channels off the same incoming T1 or E1
- Provide local TDM switching between interfaces (Drop and Insert)
- Or a mix of all the above functionalities
