<strong>C55</strong>/<strong>C55</strong>I <strong>AT</strong> <strong>COMMAND</strong> <strong>SET</strong> VERSION 1.00<br />

Parameter <strong>Description</strong><br />

(num)<br />

[0] disconnect from line and terminate call<br />

Notes<br />

• OK is issued after circuit 109 (DCD) is turned off, if it was<br />

previously on.<br />

• <strong>AT</strong>H terminates every circuit switched call (voice, data or fax), even<br />

if it is issued via another interface. This behavior is in accordance<br />

with ITU-T V.25 ter; (07/97, "Hook control": "<strong>AT</strong>H is terminating<br />

any call in progress.").<br />

• <strong>AT</strong>H clears any active PDP context or terminates any existing PPP<br />

connection, but only if issued on the same interface where GPRS is<br />

used and if there is no pending network request for PDP context<br />

activation. It does not affect PDP contexts and PPP connections on<br />

other interfaces (see also chapter "<strong>AT</strong>H Manual rejection of a network<br />

request for PDP context activation").<br />
