ISDN number String with maximum length of 20 characters. Allowed characters: +, 0-9, A, B, C.
Note:
• This command may be aborted generally by receiving a character during execution. Abortion is not possible
during some states of connection setup such as handshaking.

Notes:
• OK is issued after circuit 109 (DCD) is turned off, if it was previously on.
•
ATH terminates every circuit switched call (voice or data), 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 "ATH Manual rejection of a network
request for PDP context activation").
