ADPCM Voice Compression Server (887160) Applications
Figure 2-9. IAD in an ISDN-based ACD System
2.4.3 Wireless Base Station Application
In the application shown in Figure 2-10, the IAD is used as a channel bank at each of the
remote Base Stations. In each of the stations, the IAD is connected via T1/E1 or Analog voice
ports to the radio transmission equipment. The voice circuits that are destined for the
switching center are sent to the ADPCM voice compression server at each base station. This
compressed voice traffic is then groomed with other Base Station data traffic and transmitted
over Fractional T1/E1 lines. An IAD is used at a central location to groom the Fractional
T1/E1 lines into two T1s or E1s. These two lines are connected to the Switching Center where
an IAD with two ADPCM servers is used to decompress the voice circuits and send them to
the switch via four T1s or E1s.
