Automatic Call Distribution Application

The ADPCM server can be used to reduce leased line charges in automatic call distribution or remote call center applications by increasing the number of voice circuits supported on a single T1 or E1.

The application shown in Figure 21b illustrates an ISDN-based automatic call distribution system. The IMACS is used to provision BRI remotely via BRITE (BRI Terminal Extension). With the IMACS, ten BRI circuits can be extended to remote locations over a single T1 line, and 13 over a single E1 line. The IMACS is able to do this by placing the 2B+D signal into 2.25 time slots (1 for each B, and .25 (16Kbps) for the D channel).

The ADPCM server is used to increase the number of BRI circuits supported per T1 or E1 by compressing the B channels in voice only applications. This means that a 2B+D channel can be transported in 1.25 time slots (.5 for each B, and .25 for the D channel). Hence, 19 BRI circuits (38 voice channels) are transported over a single T1 and 24 BRI circuits are transported (48 voice channels) over a single E1.
