3.2.7.6 +A8J: - V.8 Negotiation Complete

This indication is issued by either modem when the negotiation is complete and CJ is sent or detected. An answering modem
will issue this on detection of CJ from the remote terminal. A calling modem will send a CJ signal to the remote terminal at the
same time as a +A8J indication. +A8J:1 indicates CJ; +A8J:0 indicates that the modem timed out waiting for a CJ signal.
Indication Syntax
+A8J:<value><CR>
Defined Values
<value> Decimal number corresponding to the selected option.
Example
+A8J:1 For CJ sent to a remote terminal.

3.2.7.7 +A8M: - V.8 Menu Report

This indication is issued by either modem, during V.8 negotiation, to indicate the contents of a valid received CM or JM signal.
A +A8M:0 indicates that the modem timed out waiting for a CM or JM signal.
Report Syntax
+A8M:< hex_string>
Defined Values
< hex_string> CM or JM hexadecimal coded string. A +A8M:0 indicates that the modem timed out waiting for a CM
or JM signal.
Example
A8M:XXX YYY

3.2.7.8 +A8R: - V.8bis Signal and Message Reporting

If enabled by +A8E=,,,[<v8b>=2] command, the modem monitors for V.8 bis signals and messages, and uses the +A8R:
intermediate result code response to report that signal. Two concatenated V.8 bis messages are reported with two
consecutive <message> indications.
Report Syntax
+A8R:<signal>[,[<1st message>]][,<2nd message>]<CR>
Defined Values
The V.8 bis signal, if detected, is indicated using a <signal> value (see Table 3-2). Values of 4 and 8
<signal>
are not reported, i.e., the modem is not expected to discern the power level of received CRe and
MRd signals. If a V.8 bis message is detected without a preceding V.8 bis signal, the preamble is
reported as a 0 <signal> value.
<1st message> The contents of valid V.8 bis message(s), if detected, are reported using hexadecimal octet coded
string(s) (A.4.1). Flag detection and consumption, flag transparency 0-bit deletion and FCS checking
are performed by the modem. The modem does not report invalid messages (e.g., bad FCS). If two
consecutive messages are detected but the first is invalid, the modem indicates this with no
characters between the first and second comma (e.g., +A8R:<signal>,,<2nd message>).
<2nd message See <1st message>.
Example
+A8R:0,XX,YY For a V.8 bis message detected without a preceding V.8 bis signal.
For a V.8 bis message detected with a preceding V.8 bis signal.
+A8R:0,XX,YY
