Chapter 3 System Features
I/O, Optical, and Server Modules
The DSP2C module supports ATM Adaptation Layer 2 (AAL-2) SVC
connections and PVC multiplexing for reduced call latency.
To protect facsimile transmissions, the DSP2C module automatically turns off
voice processing and echo cancellation on any channel when it detects a
modem tone.
Figure 3-12 illustrates how an Access Concentrator system using voice
processing might be deployed in a combined voice/data network.
