Voice Commands for the MT5656ZDXV and MT5600ZDXV Modems

Multi-Tech Systems, Inc. Commands Reference Guide (PN S000273D)

Unformatted Form Reporting

The MultiModem does not display the Caller ID information if it detects a checksum error in the caller ID packet

(either SDM or MDM) while in presentation mode. If the MultiModem receives multiple copies of the Caller ID

packets, the MultiModem presents all of the packets to the computer. The MultiModem presents all data items

and packet control information found in the SDM and MDM packets, except the leading Us (line seizure informa-

tion) from the presentation. The checksum is included in the presentation. The entire Caller ID packet is prre-

sented in ASCII hex as printable numbers. The characters in the ASCII hex message are in the bit order

presented to the MultiModem. The MultiModem does not insert spaces, <cr>, or <lf> ASCII codes for formatting

between the characters of the packet.

The MultiModem does not check the checksum, and it is the computers job to check message validity. Note that

this means that the MultiModem presents the Caller ID information even if the MultiModem detects a checksum

error in the Caller ID packet (SDM or MDM) in the presentation mode.

The MultiModem presents all of the information in the packet in ASCII hex as printable characters. The MultiMo-

dem includes all Mesasage Type Octets, Message Length Octets, Data Octets, and Checksum Octets for the pre-

sentation mode.

Voice Mode Shielded Codes

These codes can be sent in either Command mode or Data mode. The DCE may return the event detection re-

ports after the OK result code from the +FCLASS command. One or more simple event detection reports may be

embedded within the data portion of a complex event detection report. Table 3 describes voice mode shielded

codes. The number in the first column is the ASCII equivalent (in hex). The number in the second column refers

to the numbering scheme used below.

Shielded

Code Hex Event Report Description

<DLE> (10) Two contiguous <DLE><DLE> codes indicate a single <DLE> in the data stream.

<SUB> (1A) <DLE><DLE> in the data stream.

<ETX> (3) End Data State; signifies the end of voice data. Can end with Event 9 (Presumed

Hangup Timeout), Event 10 (Presumed End of Message), Event 13 (Loop Current

Interruption), Event 14 (Loop Curent Polarity Reversal), Event 19 (BUSY), or Event

20 (DIALTONE).

Q (51) Data stream shielded Xon character. Used in the +VXT command to shield XON

characters in the full-duplex data stream and in the Packet Protocol.

S (53) Data stream shielded Xoff character. Used in the +VXT command to shield

XOFF characters in the full-duplex data stream and in the Packet Protocol.

M (4D) Data stream shielded SOH code used for the Packet Protocol.

W (57) Data stream shielded ETB code used for the Packet Protocol.

F (46) Data stream shielded ACK code used for the Packet Protocol.

U (55) Data stream shielded NAK code used for the Packet Protocol.

G (47) Data stream shielded ENQ code used for the Packet Protocol.

T (54) Timing Mark.

X (58) Packet Header for the "Complex Event Detection Report" (additional event data

transfers to the DTE).

. (2E) Packet Terminator for the "Complex Event Detection Report" (additional event data

transfers to the DTE).

/ (2F) Start of DTMF tone shielding.

~ (7F) DTMF transitions to off.

R (52) Event Number 3 (RING). The <DLE> shielded version of the RING result code.

1 (31) Event Number 4 (DTMF 1).

2 (32) Event Number 4 (DTMF 2).

3 (33) Event Number 4 (DTMF 3).

4 (34) Event Number 4 (DTMF 4).

5 (35) Event Number 4 (DTMF 5).

6 (36) Event Number 4 (DTMF 6).

7 (37) Event Number 4 (DTMF 7).
