mixed system

# P0602812 Ver: 1.3 Page 71

mixed system A special type of digital system that contains both digital line

controllers (TPLC) and analog line controllers (VPLC).

Internally, a mixed system uses an 8K Hz PCM format for audio data

speech and recording, which is the same format used in digital

telephony. Mixed systems are configurable for both T1 and E1

telephone networks, and are comparable in performance to standard

digital systems, having similar line capacities, resource capabilities,

and data throughput.

The VPLCs in a mixed system provide analog-to-digital conversion

of audio data. This is done using PRO-2000 boards installed on the

VPLCs. All voice input/output operations in mixed systems are done

through TPLCs. In most configurations, each analog line in a mixed

system replaces the resource utilization of one digital line. Because of

this internal sharing of resources, mixed system configurations have

certain limitations.

For applications, there are no special considerations for mixed

systems. Applications associated with digital lines function as if they

were in a pure digital system; applications on analog lines function as

if they were in an analog environment.
