ETEL Telephony Architecture
ETel is the EPOC telephony server, introduced in EPOC Release 5. Its purpose is to abstract the details of controlling and working with telephone devices and services. It presents a straightforward but comprehensive telephony interface to EPOC applications.
The ETEl core API defines the basic core API which should be available to nearly all telephony hardware.
The ETel Basic GSM API is an extension to the core API, and provides access to basic GSM functionality.
The TSY Modules section lists the Basic GSM API client-side functions which have been implemented in the Basic GSM TSY shipped with ER5 - gsmbsc.tsy.
