2. TECHNICAL SPECIFICATIONS

2.1 ESTABLISHING DATA MODEM CONNECTIONS

Dialing

DTMF Dialing. DTMF dialing using DTMF tone pairs is supported in accordance with ITU-T Q.23. The transmit tone level complies with Bell Publication 47001.

Pulse Dialing. Pulse dialing is supported in accordance with EIA/TIA-496-A.

Blind Dialing. The modem can blind dial in the absence of a dial tone if enabled by the X0, X1, or X3 command.

Modem Handshaking Protocol

If a tone is not detected within the time specified in the S7 register after the last digit is dialed, the modem aborts the call attempt.

Call Progress Tone Detection

Ringback, equipment busy, and progress tones can be detected in accordance with the applicable standard.

Answer Tone Detection

Answer tone can be detected over the frequency range of 2100 ± 40 Hz in ITU-T modes and 2225 ± 40 Hz in Bell modes.

Ring Detection

A ring signal can be detected from a TTL-compatible square wave input (frequency is country-dependent).

Billing Protection

When the modem goes off-hook to answer an incoming call, both transmission and reception of data are prevented for a period of time determined by country requirement to allow transmission of the billing signal.

Connection Speeds

Data modem line connection can be selected using the +MS command in accordance with V.25 ter. The +MS command selects modulation, enables/disables automode, and selects transmit and receive minimum and maximum line speeds.

Automode

Automode detection can be enabled by the +MS command to allow the modem to connect to a remote modem in accordance with V.25 ter.

2.2 DATA MODE

Data mode exists when a telephone line connection has been established between modems and all handshaking has been completed.

Speed Buffering (Normal Mode)

Speed buffering allows a DTE to send data to, and receive data from, a modem at a speed different than the line speed. The modem supports speed buffering at all line speeds.

DTE-to-Modem Flow Control

If the modem-to-line speed is less than the DTE-to-modem speed, the modem supports XOFF/XON or RTS/CTS flow control with the DTE to ensure data integrity.

Escape Sequence Detection

The “+++” escape sequence can be used to return control to the command mode from the data mode. Escape sequence detection is disabled by an S2 Register value greater than 127.

GSTN Cleardown (K56flex, V.34, V.32 bis, V.32)

Upon receiving GSTN Cleardown from the remote modem in a non-error correcting mode, the modem cleanly terminates the call.
