The SPo pin could then be monitored by the
system processor to detect a prompt from the
peripheral.

Applications
A block diagram schematic of a simple Voice-Data
integrated switching system is illustrated in Figure 8.
The data terminal can access a number of remote
devices via the gateway provided by the Data
Codec. In this application, the Data Codec function
parallels that of the Voice Codec, i.e., the Voice
