CHAPTER 3. LEASED LINE OPERATION  
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:  
Set Normal / Config. Switch to POP position for Normal mode. Toggle the  
O/Aswitch to Answer mode or Originate mode. The LED segment displays  
‘A.’ for Answer mode, orO.’ for Originate mode.  
3. Set desired DTE speed, protocol, transmission mode, flow control, etc.  
Method:  
Set Normal / Config. Switch to PUSH position for Config mode.  
DTE speed: For example, if 57600 bps DTE speed is required, toggle the  
Menu Switch to Menu 4 (DTE speed menu), the digit ‘4’ is shown on the  
LED segment. Then toggle the Function Switch to Function 2 (speed 57600  
bps is selected), the digit‘2is shown on the LED segment.  
ACTIVE Professional External Modem User’ s Manual

CHAPTER 3. LEASED LINE OPERATION  
Then press the Enable Switch to update the DTEspeed, The characterU’ is  
shown on the LED segment.  
If more settingare required (i.e transmission mode, flow control, etc), repeat  
the above procedures.  
4. Enable the POLL after all parameters are set.  
Method:  
Set Normal / Config. Switch to PUSH position for Config mode.  
Toggle the Menu Switch to Menu 2 (type of line menu), the digit‘2’ is shown  
on the LED segment.  
Then toggle the Function Switch to Function 1 (2 wire LL is selected), the  
digit ‘1is shown on the LED segment.  
Then press the Enable Switch to enable POLL, the characterU’ is shown on  
the LED segment and all parameters will be saved to profile 0 automatically.  
5. To finish configuration by setting theNormal / Config. Switch to POP  
position.  
You will hear the sound of modem handshaking procedure. The sound will be  
on until the data connection is made.  
Procedure to exit the Power-On Leased Line(POLL)  
1. Set Normal / Config. Switch to PUSH position for configuration mode.  
2. Toggle the T/D switch to break the handshake.  
3. Toggle the Menu Switch to Menu 2 (type of line menu), the digit‘2’ is shown  
on the LED segment.  
4. Toggle the Function Switch to Function 0 (dial up line is selected), the digit  
0is shown on the LED segment.  
5. Press the Enable Switch to disable POLL, the character ‘U’ is shown on the  
LED segment and all parameters will be saved to profile 0 automatically.

APPENDIX A. AT COMMANDS  
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 ofAT”.  
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 Professional External Modem User’ s Manual

APPENDIX A. AT COMMANDS  
+++  
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 S-  
register 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 theATSn 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.

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  
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.  
The symbol * means register value may be stored in one of the two user  
profiles with the AT&Wn command. Register parameter ranges from 0 -  
255 unless specified.  
S0 *  
S1  
Number of rings till auto-answer  
Establishes the number of rings required before the modem answers  
incoming calls. Setting this register to 0 disables auto-answer mode.  
Default : 2  
Ring counter  
Default : 0  
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 *  
Escape character  
Default : 43  
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  
S4  
Carriage return character (Range :0-127)  
Sets the command line and result code terminator character. Pertains to  
asynchronous operation only.  
Default : 13  
Line feed character (Range:0-127)  
Default : 10  
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.  
S5  
Backspace character (Range:0-32)  
Default : 8  
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

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 off-  
hook 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 *  
S9 *  
Pause time for dial delay  
Sets the length of time in seconds to pause when the modem encounters  
the "pause during dial" call progress feature, i.e., the comma.  
Default : 2  
Carrier detect response time (Range :1-255)  
Default : 6  
Determines the duration in tenth of asecond 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 *  
S12 *  
DTMF tone duration (Range :50-255)  
Sets the duration in millisecond of tones in DTMF (Dual Tone Multi  
Frequency) dialling. This value has no effect on pulse dialling.  
Default : 95  
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  
Pertains to synchronous operation only. When CTS tracks RTS  
Default : 1  
(AT&R0) and the modem detects an ON-to-OFF transition on RTS, this

Flash Dial Modifier Time  
Default : 25  
Sets the length of time, in units of 10 ms, that the modem will go on-  
hook when it encounters the flash (!) dial modifier in the dial string. The  
time can be limited as it is a country dependent parameter.  
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.
