3.VOICE OVER ATM APPLICATION

You can upgrade the T1 RCU for VoATM by adding the Echo Canceller (see the Echo Canceller User Interface Guide, document number 61200384L1-31). The Echo Canceller is used in ATM voice applications that require G.168 echo cancellation. The RCU must be using Voice Over ATM firmware to be able to use this module. The module is available with and without ADPCM.

Figure 1 shows a typical VoATM application. The TA 850 connects to the ATM Network to provide both voice and high speed data from a single platform.
