low for GPRS and multiplex mode.

ously on.

Parameter

<n> 0 terminate call

Reference

V.25ter

Note

Using ATH in Multiplex mode (AT+CMUX):

· ATH terminates every voice, fax or CSD call, no matter on which channel ATH

was executed.

For example, if ATH is executed on channel 2 or 3, a voice call m ade on chan-

nel 1 will be disconnected, too.

This behaviour is in accordance with ITU-T V.25 ter; (07/97, see “6.3.6 Ho ok

control“: "ATH is terminating any call in progress").

Using ATH while GPRS is active during Multiplex mode:

· ATH clears an active PDP context or term inates an existing PPP connection,

but only if issued on the same logical channel where GPRS is used . It does not

affect PDP contexts and PPP connections on other channels.

· See also Chapter 6.3.2, ATH Manual rejection of a network request for PDP

context activation.
