While autobaud is operating, the modem searches for the "A" or "a" which begins an "AT" command sequence. It determines the data rate from this character and tests the next character received to see if itis a"T" or "t. If the "AT" or "at" sequence is detected, parity and bit lengths are determined from the two, and the remainder of the command line is parsed after a carriage return is detected. If the command buffer overflows, or if a parity or framing error is detected, autobaud operation will resume. The modem will autobaud to speeds of 300, 600, 1200, 2400, 4800, 7200, 9600, 14400, 19200, 38400, and 57600 bits/s.

D-9AT&T V32x-V42D DeskTop Complete Modem Chip Sets ~ AT & T MELEC (I ) b4E D MM 0050026 0009439 995 MBATTe User Information (continued) Blind Dialing Blind dialing allows the modem to not detect dial tone prior to dialing. The modem can be configured to dial from 2 seconds to 255 seconds after going off-hook by changing the value in S register 6. The default time, as well as minimum time, is 2 seconds. Pulse Dialing The ATDP command designates that subsequent dialing operations will use pulse dialing. The modem pulse dials at a rate of 811 pulses/s. AT&PO selects the default make/break ratio of 39% make to 61% break. AT&P1 selects an alternate ratio of 33% make to 67% break required in some countries. DTMF Dialing Table 4 lists the DTMF tone pairs used for tone dialing. All tones are generated within +1.5%, conforming to Bell System Communications Technical Reference Publication 47001 dated August 1976. Table 4. DTMF Tones High Frequency (Hz) 1209 1336 1477 | 1633 Low 697 1 2 3 A Frequency | 770 4 5 6 B (Hz) 852 7 8 9 Cc 941 * 0 # D Ring Detection A ring signal between 15 Hz and 68 Hz will be detected. Call Progress Frequency: 340 Hz640 Hz Level: On >-43 dBm Busy Timing: 500 ms + 10% (2 cycles) = Normal busy Reference: Bell System Technical Reference PUB 61100. Answer Tone Detection The answer tone detection range for CCITT V.32bis, V.32, V.22bis, V.22, V.21, and V.23 is 2100 Hz + 40 Hz. The detection range for Bell 212A and 103 is 2225 Hz + 40 Hz. The detection level for both CCITT and Bell answer tones is greater than or equal to -43 dBm. Billing Protection The answering modem must remain silent for a period of time to allow the network administration to send billing information between central offices. After going off-hook, the modem must wait at least 2 seconds before sending answer tone. D-10AT&T V32x-V42D DeskTop Complete Modem Chip Sets AT & T MELEC (I ) bYE D MM OOSO02b 0009440 300 MMATT2 ~ User Information (continued) Automode Automode from V.32bis to V.22bis is implemented according to V.32 annex A (11/22/90), and automode to V.21, Bell 103, and Bell 212A is implemented according to the EIA.TIA draft standard from subcommittee TR-30.1. Modem Handshaking Protocol The calling modem aborts the call if it does not detect carrier after the time period defined in S register 7. The default time is 30 seconds. Phone Number Dialing The modem can dial numbers entered in the command buffer or dial stored numbers. When the D is detected in the command, the following characters in the command buffer are treated as digits or dial modifiers. The dial digits are O9, A, B, C, D, #, and *. Dial Modifiers Pulse dial (default). Tone dial. Pause for number of seconds in S register 8. Hook-flash (on-hook for 1/2 second). Wait for at least 1 ring followed by 5 seconds of silence. Wait for dial tone for number of seconds in S register 7. Return to COMMAND mode after dialing. n _ Dial stored number in directory entry n. Originate in answer mode (go to answer mode after dialing). Dp Z=Q-" AV Stored Numbers The AT&Zn=x command sets the contents of directory entry n, which can be 0 through 3, to be the dial string x. Up to 36 characters can be stored in a directory entry. The only dial modifier which cannot be stored is S. Answering The modem will answer an incoming call when the ring counter (S register 1) equals the ring to answer on (S register 0), unless S register 0 = 0 or unless DTR is required and is not true. The AT&Dn commands govern the use of DTR. AT&D2 causes the modem to disable autoanswer on an on-to-off transition of DTRand to re- enable autoanswer on an off-to-on transition of DTR. The other AT&Dn commands cause DTR to not affect the autoanswer function. The modem may also be caused to answer manually with the ATA command. Stored Profiles After the user has set up the modem for a particular configuration, that configuration may be stored as one of two user profiles which can be recalled at any time. The AT&Wn command will store the current modem configuration as user profile n, where n can be 0 or 1. Either profile can be recalled at any time with the ATZn command. Likewise, either profile can be designated to be the default configuration at powerup with the AT&Yn command. The AT&V command displays the active configuration and both stored profiles. The factory configuration can be made the active configuration with the AT&F command. D-11AT&T V32x-V42D DeskTop Complete Modem Chip Sets AT & T MELEC (I ) BYE D M@@ OOS0026 0009441 24? MBATTe User Information (continued) Data Mode Flow Control The modem provides the ability for the data terminal or computer port to pause the flow of data from the modem and for the modem to pause the flow of data from the data terminal or computer port. Flow control is required when a DTE cannot handle data as fast as it is received. Two types of flow control are provided: EIA flow control (RTS-CTS) and XON/XOFF flow control. Escape Sequence Detection S register 2 contains the decimal representation of the ASCII character used to enter COMMAND mode. The factory default is a decimal 043, the plus (+) character. A value of 128 or greater disables the escape function. Break Detection The modem detects a BREAK signal from either the DTE or the remote modem. The following table summarizes the modem's response to a received BREAK signal depending on the AT\K command. The default value is \K5. (In connect state, if reliable mode or normal mode, then transmit break to remote) 0, 2, 4: Enter command state but do not send a break 1: Destructive/Expedited. 3: Nondestructive/Expedited. 5: Nondestructive/Nonexpedited. (In command state and transmit break command issued, if reliable mode or normal mode, then transmit break to remote) 0,1: Destructive/Expedited. 2,3: Nondestructive/Expedited. 4,5: Nondestructive/Nonexpedited. (in connect state, if direct mode, then receive break at serial port) 0, 2, 4: Immediately send break and enter command state. 1,3, 5: Immediately send break through. (In connect state, if normal mode, receive break at modem port, send to serial port) 0,1: Destructive/Expedited. 2,3: Nondestructive/Expedited. 4,5: Nondestructive/Nonexpedited. Telephone Line Monitoring Loss of Carrier S register 10 specifies the amount of time (0 to 255 in 1 tenth of a second increments) needed to recognize the loss of carrier. The default is fourteen-tenths or 1.4 seconds. Long-Space Disconnect The Y command allows the user to control the operation of long-space disconnect. When enabled, the modem will terminate the connection if it receives a break 1.6 seconds in length, and will send a break four seconds in length prior to any controlled disconnect. D-12AT&T V32x-V42D DeskTop Complete Modem Chip Sets BYE D MM OOS002b oo09442 183 MATT2 AT & T MELEC (I C) User Information (continued) Error Control At 1200 bits/s14400 bits/s, the modem operates in full compliance with CCITT V.42, the international standard for point-to-point modem error control. Link access procedure for modems, more commonly referred to as LAPM, is the primary protocol, and annex A, the alternate protocol provides backward compatibility with MNP (Microcom Network Protocol) Classes 2 through 4. MNP and V.42 selections are performed via the \N commands. MNP or V.42 negotiation, if enabled, is automatic when a call is placed or received. The communicating modems will arrive at the highest class of MNP supported by both before data transmission begins. Data Compression The AT&T V32x-V42D supports CCITT V.42bis, the international standard for data compression which provides compression capabilities up to 4:1, for use by modems incorporating the V.42 LAPM error control standard. MNP Class 5 provides capabilities up to 2:1 compression. The "H3 command enables V.42bis data compression. The %C1 command enables MNP 5 data compression. Programmable Inactivity Timer The inactivity timer is the length of time the modem will wait before disconnecting when no data is sent or received. This timer is set using the \Tn command. It is programmable between 0 and 90 minutes. The default value is 0 (disabled). Modem Testing The following tests are available for testing the local modem and for testing of a remote modem. Analog Loopback Tests These tests verify the operation of a local modem without use of a telephone line or a remote modem. Local Analog Loopback These tests take characters from the local terminal and send them from the modem transmitter to the modem receiver, where they are echoed back to the terminal. The two tests are identical, except that AT&T10 tests the low-frequency channel of the modem and AT&T1A tests the high-frequency channel. Start the test with AT&T10 or AT&T1A. Type a few lines to test if the data echoes back correctly. Return to COMMAND mode via the escape sequence. Issue the AT&TO command to stop the test. Local Analog Loopback with Self-Test Set the test timer to a number of seconds (1255) to run the test. Start the test with AT&T8. The modem will generate a test message to its own receiver and verify its reception. At the end of the test, a number between 0 and 255 will be displayed indicating the numbers of errors during the test. Digital Loopback Tests These tests verify a local or remote modem's operation. By default, the modem will allow loopback tests ordered by a remote modem. This feature can be enabled and disabled by the user. The AT&T5 command will cause the modem to deny remote digital loopback (RDL) requests from the remote modem. The AT&T4 command will cause the modem to grant RDL requests from the remote modem. Remote Digital Loopback (RDL) This test commands the remote modem to send back all of the data it receives. Initiate a connection with the remote modem, and then enter COMMAND mode and issue the AT&T6 command. The data typed should echo back without error. Enter COMMAND mode and issue the AT&T0 command to end the test.

Establish a connection with the remote modem and start the test with AT&T7. The local modem will generate a test message and send it to the remote modem. The remote modem will send back the data it receives. The local modem will verify its reception. At the end of the test, a number between 0 and 255 will be displayed indicating the numbers of errors during the test. Local Digital Loopback This test causes the local modem to send back everything it receives from the remote modem. Establish a connection with the remote modem, and then enter COMMAND mode and issue the AT&T3 command. The operator at the remote modem should type some data and verify that it echoes back properly. Enter COMMAND mode and issue AT&TO to end the test. Hardware Interface The AT&T V32x-V42D hardware interface signals for the serial and parallel interfaces are shown in Figures 2 and 3.
