Appendix A AT Commands 2 Enables DTE-controlled V.8 negotiation. +A8T=,,,,,-Send V.8 bis Signal and/or Message This command instructs the DCE to send a V.8 bis signal or message. This command is only supported when V.80 is enabled. Valid Values: 0 None. 1 Initiating Mre. 2 Initiating MRd. 3 Initiating CRe, low power. 4 Initiating CRe, high power. 5 Initiating CRd. 6 Initiating Esi. 7 Responding MRd, low power. 8 Responding MRd, high power. 9 Responding CRd. 10 Responding Esr. Valid Values: 0 Enables detection of initiation signals (default). 1 Enables detection or responding signals. Valid Values: 0 Disables detection of messages (default). 1 Enables detection of V.8 bis messages. Valid Values 0 No delay inserted (default). 1 Inserts a 1.5 s delay between transmitted V.8 bis signal and the subsequent V.8 bis message. +DR-Data Compression Reporting Use this command to enable or disable the compression report. If the compression report is enabled, the +DR: intermediate result code reports the current DCE-DCE data compression type. It is issued after the error control report (+ER) and before the final result code (e.g., CONNECT). 47

Enables DTE-controlled V.8 negotiation.
+A8T=<signal>,<1st_message>,<2nd_message>,<sig_en>,<msg_en>,<su
pp_delay>±Send V.8 bis Signal and/or Message
This command instructs the DCE to send a V.8 bis signal or message. This
command is only supported when V.80 is enabled.
Valid <signal> Values:
0
None.
1
Initiating Mre.
2
Initiating MRd.
3
Initiating CRe, low power.
4
Initiating CRe, high power.
5
Initiating CRd.
6
Initiating Esi.
7
Responding MRd, low power.
8
Responding MRd, high power.
9
Responding CRd.
10
Responding Esr.
Valid <sig_en> Values:
0
Enables detection of initiation signals (default).
1
Enables detection or responding signals.
Valid <msg_en> Values:
0
Disables detection of messages (default).
1
Enables detection of V.8 bis messages.
Valid <supp_delay> Values
0
No delay inserted (default).
1
Inserts a 1.5 s delay between transmitted V.8 bis signal and the
subsequent V.8 bis message.
+DR<value>±Data Compression Reporting
Use this command to enable or disable the compression report. If the
compression report is enabled, the +DR:<type> intermediate result code
reports the current DCE-DCE data compression type. It is issued after the
error control report (+ER) and before the final result code (e.g., CONNECT).
