7.9 ATH Disconnect existing connection
Syntax
Command Description
Disconnect existing call from command line by local TE and terminate call.
Parameter Description
[0] disconnect from line and terminate call
Notes
OK is issued after circuit 109 (DCD) is turned off, if it was previously on.
ATH terminates every circuit switched call (voice, data or fax), even if it is issued via another interface. This
behavior is in accordance with ITU-T V.250; (07/97, "Hook control": "ATH is terminating any call in progress.").
ATH clears any active PDP context or terminates any existing PPP connection, but only if issued on the same
interface where GPRS is used and if there is no pending network request for PDP context activation. It does
not affect PDP contexts and PPP connections on other interfaces (see also Chapter "ATH Manual rejection
of a network request for PDP context activation").
