Table 3: Connection Monitor Server API definitions| ETel | Symbian OS Telephony Server |
| Connection | In this document, connection refers to an IAP level connection. If
two applications have a data connection activated with the same IAP (and therefore
the same network interface), the number of connections is 1. Identified with
a connection ID. |
| Subconnection | A PDP context within a certain IAP. The existing connection has always
at least one subconnection. Currently valid only in case of GPRS/UMTS. If
secondary PDP contexts are not used, subconnection means almost the same as
connection. Identified with a subconnection ID. Support for sub- connections
is not implemented. |
| Client of connection | An application using a certain connection. Identified with UID. |
| Internal connection | An internal connection has been started by an application running in
the phone. |
| External connection | An external connection has been started by an application running e.g.
in the PC and the phone is used in modem mode. |
| IAP availability | An IAP is available, if there is an active connection through this
IAP, or there is a possibility to start a connection through this IAP right
away. |
| SNAP availability | A SNAP is available, if there is any available IAP inside this SNAP. |
