CHAPTER 3. LEASED LINE OPERATION
9
CHAPTER 3. LEASED LINE OPERATION
This chapter tells you how to establish a leased line connection in asynchronous and
synchronous modes.
What is Leased Line Operation?
In leased line operation, two modems are directly wired together by a dedicated
telephone line. The register S7 does not pose a time limit on making a data connection.
One modem must be set to originate mode and the other must be set to answer mode.
ACTIVE modem is designed to be used with a 2-wire / 4- wire(optional) leased line
The RS-232C DTR signal must be ON to maintain the leased line data connection. If
the modem detects a DTR drop during data connection, the carrier will be dropped.
Once the DTR signal is restored to ON, the modem will re-start to establish data
connection. The user can use the AT&D0 command to cancel the effect of DTR status
on this operation. In this case, the modem will perform this operation disregard of the
DTR status.
Asynchronous Power-on Leased Line (POLL) Operation
When the modem is set to POLL mode, the carrier is transmitted immediately upon
powered up. The modem will wait for the remote carrier eternally until data
connection is established. If the modem detects a loss of carrier during data
connection, it will send the carrier for a re-connection automatically.
The following is an example to establish a Power-on 2-wire leased line (POLL)
operation, Please follow the instructions below:
1. Make proper wiring connection.
2. Prepare two modems. One modem set to Answer mode, another one set to
Originate mode.
Method:

APPENDIX A. AT COMMANDS
11
APPENDIX A. AT COMMANDS
The PC or terminal communicates with the modem through the use of the AT
commands. Your communication software will act as an interface between you and
your modem. You read this chapter to customise your configuration.
To issue these industry-standard "AT" commands, first load a communication
software package and then enter Terminal or Interactive Mode (Refer to your
communication software manual).
All command lines must begin with the ASCII letters "AT" and end with "<Enter>"
except for the A/ command and escape characters (default +++), which will be
discussed later. The letters "AT" are sometimes referred to as an attention code. This
command indicates to the modem that one or more commands are to follow. The
"AT" and all following alphabetic characters may be in upper or lower case.
AT must be entered in the same case such as "AT" or "at".
"At" or "aT" are not permitted.
A series of commands can be grouped in a single line. The commands can be entered
in a string with or without spaces for readability. Spaces within or between
commands are ignored. The maximum number of characters in any command line is
39 (including “AT”). During the entry of a command, the backspace key can be used
to correct errors with the exception of “AT”.
If a syntax error is found anywhere in a command line, the remainder of the line will
be ignored and the ERROR result code will be returned. Most commands entered
with parameters out of range will not be accepted and the ERROR result code will be
returned.
This chapter lists all the commands used to configure the modem. It includes
standard Hayes AT commands, Hayes V-series commands and extended commands
to control ACTIVE modem.
DESCRIPTION OF AT COMMANDS
The symbol * means command setting may be stored in one of the two user
profiles with the AT&Wn command.
A/ Re-execute command
Re-executes the most recent AT command string. The principle
application of connect due to a busy line, no answer, or a wrong number.
This command must appear alone in a command line and must be
terminated by the “/” character. (A <Enter> should not be entered to
end the command.)
ACTIVE Professio nal External Modem User’s Manual
APPENDIX A. AT COMMANDS
12
+++ Escape Characters Default : +
Switch the modem from Online State to Command State without
breaking the data connection. This character can be redefined by
changing the value in S Register S2.
AT=x Write to Selected S Register
This command writes the value x to the currently selected S register. An
S register can be selected by using the ATSn command. All of the Sregister will return the OK response if x is a number.
AT? Read Selected S Register
This command reads and displays the selected S register. An S register
can be selected by using the ATSn command.
ATA Answer
This must be the last command entered into the command line. The
modem proceeds with the connect sequence in answer mode. The
modem will enter the connect state after exchanging carrier with the
remote modem. If no carrier is detected within a wait period specified in
register S7(default = 50 seconds), the modem will disconnect. Any
character may be entered via the DTE during the connect sequence to
abort the command.
ATBn * Set ITU-T or Bell mode Default : 0
ATB0 Selects ITU-T V.22 and V.21 standards for communication at
1200 and 300bps
ATB1 Selects Bell 212A and 103 standards for communication at
1200 and 300bps
ATCn Carrier control Default : 1
This command is included for compatibility only, and has no effect
other than returning a result code.
ATC1 Normal transmit carrier switching
ATDn Dial
This must be the last command in a command line. ATD causes the
modem to go off-hook, dial according to the parameters entered, and
attempt to establish a connection.
If there are no parameters, then the modem goes off-hook in originate
mode without dialling a number.
Punctuation may be used for clarity. Parentheses, hyphens and spaces
are ignored. If an invalid character is entered, that character and all
subsequent characters in the dial string are ignored. The modem
truncates dial strings to 36 characters.

APPENDIX C. S REGISTERS
Your ACTIVE modem has a number of S registers that affect various operation
characteristics, let you obtain information about your modem, and let you test and
configure your modem. Most of the registers have default values, which you can
display or change to fit your particular requirement.
profiles with the AT&Wn command. Register parameter ranges from 0 255 unless specified.
S0 * Number of rings till auto-answer Default : 2
S1 Ring counter Default : 0
S2 * Escape character Default : 43
Establishes the number of rings required before the modem answers
incoming calls. Setting this register to 0 disables auto-answer mode.
Number of rings which the modem detects before it answers a call. If no
rings occur over an 8 second interval, this register is cleared.
S2 holds the decimal value of the ASCII character used as the escape
character. The default value corresponds to an ASCII '+'. A value over
127 disables the escape process, i.e., no escape character will be
recognized.
S3 Carriage return character (Range:0-127) Default : 13
S4 Line feed character (Range:0-127) Default : 10
S5 Backspace character (Range:0-32) Default : 8
ACTIVE Professio nal External Modem User’s Manual
Sets the command line and result code terminator character. Pertains to
asynchronous operation only.
Sets the character recognized as a line feed. Pertains to asynchronous
operation only. The line feed control character is output after the
carriage return control character if verbose result codes are used.
Sets the character recognized as a backspace. Pertains to asynchronous
operation only. The modem will not recognize the backspace character
if it is set to a value that is greater than 32. This character can be used to
edit a command line. When the echo command is enabled, the modem
echoes back to the local DTE the backspace character, an ASCII space
character and a second backspace character; this means a total of three
characters are transmitted each time the modem processes the
backspace character.
APPENDIX C. S REGISTERS

S6 * Wait time for blind dialling (Range:2-255) Default : 2
Sets the length of time in seconds to pause after the modem goes offhook and before the modem dials the first digit of the telephone number.
The modem always pauses for a minimum of 2 seconds even if the S6
register is set to a value less than 2 seconds. The "wait for dial tone" call
progress feature (W in the dial string) will override the value in register
S6. If option ATX2 or ATX4 is in effect, this register is ignored.
S7 * Wait for carrier after dial (Range:1-255) Default : 50
Defines two delay times in seconds:
1. During call establishment, this register establishes the time that the
local modem waits for carrier from the remote modem before
hanging up.
2. Sets the length of time that the modem waits when the "wait for dial
tone" call progress feature (W in the dial string) is in effect.
S8 * Pause time for dial delay Default : 2
Sets the length of time in seconds to pause when the modem encounters
the "pause during dial" call progress feature, i.e., the comma.
S9 * Carrier detect response time (Range:1-255) Default : 6
Determines the duration in tenth of a second which a carrier signal must
be present before the modem recognizes it as a carrier. As this time is
increased, there is less chance to detect a false carrier due to noise from
the telephone line.
S10 * Lost carrier to hang up delay (Range:1-255) Default : 14
Sets the length of time in tenth of a second which the modem waits
before hanging up after a loss of carrier. This allows for a temporary
carrier lost without causing the local modem to disconnect. When
register S10 is set to 255, the modem functions as if a carrier is always
present.
The actual interval the modem waits before disconnecting is the value
in register S10 minus the value in register S9. Therefore, the S10 value
must be greater than the S9 value or else the modem disconnects before
it recognizes the carrier.
S11 * DTMF tone duration (Range:50-255) Default : 95
Sets the duration in millisecond of tones in DTMF (Dual Tone Multi
Frequency) dialling. This value has no effect on pulse dialling.
S12 * Escape code guard time Default : 50
Sets the time delay in fiftieth of a second required immediately before
and after entering the escape code. The time interval between the
sending of the first and second, or the second and third escape code
characters must be less than the value of the guard time.

S25 Delay to DTR Default : 5
Register S25 serves two purposes. When the modem is operating in
synchronous mode 1, the value assigned to S25 specifies the length of
time which the modem waits after a connection has been made before
examining DTR. This allows the modem to ignore an ON-to-OFF
transition of DTR giving the user sufficient time to disconnect the
modem from the asynchronous terminal and attach it to a synchronous
terminal, without forcing the modem back to the asynchronous
command mode. During this time, the value for S25 is read in seconds
(e.g., the factory-set value of 5 equals 5 seconds).
In all other modes, and after call establishment in synchronous modes 1
and 4, the value is read in 1/100 second. In any mode, a change in DTR
(ON or OFF) that persists for a period shorter than the value held in S25
is ignored by the modem while it is in data mode.
S26 RTS to CTS delay interval Default : 1
Pertains to synchronous operation only. When CTS tracks RTS
(AT&R0) and the modem detects an ON-to-OFF transition on RTS, this

S29 Flash Dial Modifier Time Default : 25
Sets the length of time, in units of 10 ms, that the modem will go onhook when it encounters the flash (!) dial modifier in the dial string. The
time can be limited as it is a country dependent parameter.
S30 Disconnect Inactivity timer Default : 0
Determines the length of time, in tenth of a second intervals, that the
modem will wait before disconnecting when no data is sent or received.
In MNP or V.42 mode, any data transmitted or received will reset the
timer. In other modes, any data transmitted will reset the timer. The
inactivity timer is incorporative in synchronous mode.
