Comment
0x08 = AG role of HSP (bitmask), needs subsequent
“AT&W” and “atz” to activate
Responses:
successful: “CONNECT 123456789012,1108,>”
failed: “NO CARRIER”
wrong state: “ERROR 63”
profile disabled: “ERROR 59”
An existing SLC is required. RING / in-band-ringing is
controlled by S346. Automatic alerting can be config-
ured using S345.
HSG must be in alerting state (ATI64=5 or =6)
HSG will stop sending RING-message or release audio
(in-band ringing)
An existing SLC is required
Response:
successful: “OK” and “HSG”AU0”
wrong state:” ERROR 63”
profile/role disabled: “ERROR 59“
Response:
successful: NO CARRIER 1112
(AG(HSP) was connected previously)
wrong state:” ERROR 63”
profile/role disabled: “ERROR 59“
0 = disable auto alerting
1 = auto alerting on outgoing ACL established
2 = auto alerting on incoming ACL established
3 = auto alerting on outgoing and incoming ACL
established
0 = disable in-band ringing
1 = enable in-band ringing
0 =disable
1 = ACL will be released automatically when audio was
released by the HS.
0 = not connected
1 = ACL connected
