3 Connecting 
State after opening a service with AT^SISO where the connection is being
established. 
If connection setup is successful the service proceeds to the state "4" (Up) and
one of the URCs "^SISW" and "^SISR" may follow. If connection setup is not
successful, the "^SIS" URC may appear and the service enters <srvState>
6 (Down). 
In the case of FTP, <srvState>=3 means that the command channel is being
established.
If the service profile is configured as Socket listener, then the listener always
stays at <srvState>=3 and <socketState>=3 (LISTENER), while the
<srvState> and <socketState> of the dynamically assigned service pro-
file may change. See examples in Section 10.15.4 and Section 10.15.5.
4Up
The service performs its purpose. The data transfer process is the major func-
tion at this state.
FTP: Data channel is up.
SMTP: The SMTP service will not enter <srvState>=4 until the host has writ-
ten the first data packet with AT^SISW.
5 Closing 
Internet Service is closing the network connection.
FTP: Command channel is released.
6 Down 
This state is entered if 
- the service has successfully finished its session (see note on Socket), 
- the remote peer has reset the connection or 
- the IP connection has been closed because of an error (see note below on
service or network errors). 

If a service in this state be sure to close it with AT^SISC before reopening it.
