Introduction

LineMan is a central office phone line simulator designed to work with standard North American

phones and telephone related devices. It is compatible with telephones, answering machines,

voice mail systems, fax machines, and data modems. Its high quality audio allows for clear voice

communication and it even supports high speed analog data calls.

LineMan is very sophisticated but easy to operate. Although you can use it as-is, you can also

customize it for your special applications. For example, you can alter its operating mode, reorder

tone behavior, network delay time, and more. Entering simple codes from a TouchTone (DTMF)

telephone is all that is needed to program the various features. Most users will not need to do this,

but if you do, it is a simple process.

Telephone Dialing Format

LineMan accepts TouchTone or Pulse (rotary) dialed phone numbers. The called number can be

any local or long distance phone number that follows the North American dialing standard. The

local numbers use the xxx-xxxx format and the long distance numbers are 0/1-(xxx)-xxx-xxxx.

You can also call using a “Quick Ring” short cut method. Anytime you hear dial tone you may

press the phone’s Star key twice (ww) to start a ring cycle.

Special Phone Numbers

There are several phone numbers that simulate those commonly used by your local phone

company. Here is a summary:

Phone Number Name Comment

0 Local Operator Rings after fixed 8 second delay + network delay.

00 Long Distance Rings after network delay time.

Operator

311 E-311 Non-Emergency 311. Two short stuttered rings.

411 Information Telephone Company “information” number.

611 Repair Service Telephone Company “repair” number.

911 E-911 Emergency 911. Three short stuttered rings.

INE

Telephone Line Simulator Page 4 December 2007

Emergency 911 and Non-Emergency 311 Training Feature

The emergency 911 feature is perfect for E-911 training, which is a popular subject in many grade

schools. Dialing “911” will cause the phone’s bell to ring using a special stuttered ring pattern.

This allows for easy identification of E-911 calls. To maintain realism, the caller always hears a

normal ring tone.

The E-911 ring pattern’s cadence is three short rings followed by the standard four seconds of

silence. After the call is answered, a short beep is heard every ten seconds. This beep simulates

the typical tone heard on calls that are being monitored by recording equipment.

LineMan also supports “311,” the non-emergency safety number. It will also cause the phone’s

bell to ring using a stuttered ring pattern. The cadence is two short rings followed by the standard

four seconds of silence. The simulated two-way record beep is present too.

Both the stuttered ring and beep tone can be disabled (please see the System Programming

Section).

Test Phone Numbers

There are several pre-assigned phone numbers to test dialing equipment. Although these

numbers will generate test tones, they do NOT disturb the called line. Here is a summary:

Test Number Name Comment

123-4567 Irregular Number Unacceptable number. Reorder tone (fast busy).

767-1000 Busy Signal Standard busy signal.

767-1001 Ringing Tone Standard ring signal.

767-1002 Network Busy Reorder tone.

767-1003 Test Tone 620 Hz test tone. Audio level is -14 dBm (±3dBm).

CLASS Feature (Recall Dial Tone)

Whenever you begin a dialing sequence with “w,” followed by two digits (00-99), you will hear

three short beeps. This tone sequence is called Recall Dial Tone and is similar to the beeps heard

on some phone systems during special dialing modes. These special dialing codes are similar

to those used by the Public Switch Telephone Network’s (PSTN) CLASS features.

Note: The

47 code sequence is reserved for System Programming.

Manual CPC Request (w50)

The CPC signal is essentially the removal of talk current for about one-half second and normally

occurs when the caller hangs up. It is used to help some phone devices hang up at the end of a

call. Since the CPC signal is handled automatically, there is really no need to send it manually.

But if you wish to do so, just dial w50 when you hear dial tone.

INE

Telephone Line Simulator Page 5 December 2007

System Programming

The System Programming feature allows you to adapt LineMan to your special application. If your

needs are not met by the factory default settings, then perhaps one of the programmable features

will.

All programming codes are six digits long and are entered using a TouchTone (DTMF) phone.

They always begin as “w47,” followed by a two digit operation code, then ended with a trailing “w.”

If you do not correctly follow the order the code will be ignored.

Table 1 offers a quick summary of the programming codes. The items marked as “D

EFAULT

?” are

the standard power-up settings (as shipped from the factory). The items marked as “

SAVE

?” are

those that can be stored in memory as a power-up default setting.

Please be aware that these codes are only valid when dial tone is present. You will hear three

beeps after entering the code, followed by a new dial tone. A busy signal indicates that an

undefined code has been entered.

Operating Modes

LineMan can work just like a normal telephone line or it can provide special operating modes.

You can select the different modes anytime you have dial tone. Here is a summary:

Dialed Code Name Comment

w4701wNormal Operation. Normal line simulation.

w4702wRing-Down Line. Ring whenever phone goes off-hook.

w4703wSilent Talk Path. No call progress tones. Manual Ring.

Normal Mode w4701w

The Normal mode is used when you want standard telephone system emulation. When

you take the phone off-hook, a dial tone is heard. If you do nothing for twenty-five seconds,

a “reorder” sound is heard. If you dial a typical seven or eleven digit phone number then

the phone will start to ring. If you attempt to ring a line that is off-hook, then a busy signal

will be heard.

There are some shortcuts in the Normal mode that can be used to ring a line. For

example, pressing the phone's “w” key twice will immediately start the ring request. If the

CLASS mode has been disabled then only one wis required. The quick ring feature can

be disabled (please see the System Programming Section).

The Normal mode is perfect for demonstrating telephone equipment such as answering

machines, fax systems, voice mail, modems, and more! Because the standard call

progress audio tones are heard, your telephone call will appear very realistic to your

audience and your telephone equipment.

Please note that all the operational modes are set while in the “Normal” mode. Anytime you

hear dial tone you can enter the code for the other modes. If you are in the other modes

and wish to return to the Normal mode, then just press the # (pound) key.

Ring-Down Line Mode, w4702w

The Ring-Down Mode is designed to start the ring cycle merely by lifting a telephone off-

hook. The ringing can be delayed for up to nine seconds, as set by the Auto dial time

(programming code w471Xw).

INE

Telephone Line Simulator Page 7 December 2007

You can cancel this mode and revert to the Normal

mode by pressing #(pound) within two

seconds of going off-hook. You will hear a short beep followed by dial tone if it has been

canceled.

This mode is perfect for use as a front entry intercom for home or office use. Place a

phone near you and one near your entry. Be sure to post a note near the entry phone that

instructs your visitors to “lift the receiver for assistance.”

Silent Talk Path Mode, w4703w

The Silent Talk Path mode provides simple talk battery and allows for a manual ring. You

will not hear any call progress tones. However, you can converse normally. The phone’s

“w

w” key controls ringing. The ring signal will follow the key presses. Unlike the other

modes, the ringing does not continue after the button is released.

You can cancel this mode and revert to the Normal mode. To do so, take a phone off-hook

and press #. You will hear dial tone if it has been canceled.

This mode is used for testing basic telephone operation. Because you can control the

cadence of the ring signal, nonstandard equipment can be tested for ring operation.

Ring-Down Delay Feature (w471xw)

You can choose to delay the time before ringing on calls made in the Ring-Down mode. To

change the value, obtain dial tone and enter w471xw, where x is the delay time as shown below.

w471xwRing-Down Delay Codes

w4710w= No Delay w4715w= Five Seconds

w4711w= One Second w4716w= Six Seconds

w4712w= Two Seconds w4717w= Seven Seconds

w4713w= Three Seconds w4718w= Eight Seconds

w4714w= Four Seconds w4719w= Nine Seconds

To enter the delay code it will be necessary to exit the Ring-Down mode. This can be done by

going off-hook and pressing #(pound) within two seconds. After entering the new delay value,

you can restore the Ring-Down mode by entering code w4702w.

Network Delay Code Setting Feature (w472xw)

You can choose the network delay that is used during calls made in the Normal mode. The delay

simulates the short pause before ringing or busy signals. To change the value, obtain dial tone

and enter w472xw, where x is the delay time as shown below.

w4722w= Two Seconds w4727w= Seven Seconds

w4723w= Three Seconds w4728w= Eight Seconds

w4724w= Four Seconds w4729w= Nine Seconds

CPC Feature (w4742w/ w4743w)

When the caller disconnects, a momentary interruption of the phone line current occurs to

simulate the central office’s Calling Party Control (CPC) feature. You can turn off the CPC feature

by dialing w4742wor turn it on by dialing w4743w. We recommend that you leave it enabled.

Pulse Dial Disable (w4746w/ w4747w)

Both Pulse and DTMF dialing is supported. Code w4746wwill turn off pulse dial detection and

code w4747wwill turn it on. DTMF dialing remains enabled in both cases.

System Reset and Parameter Check (w4752w)

This code will cause the unit to reset and is the same as if you cycled power. It also checks the

stored settings for invalid entries. First you will see the three LED’s turn on. Then they will quickly

turn off in sequence. After a short delay the line that is in-use and Status LED will turn on.

However, if the Status light blinks then a problem has been discovered with the saved settings.

At the end of the test, dial tone will be heard.

Restore Factory Settings (w4755w)

This code will restore all of the factory default settings. These are not automatically saved, so you

will need to use the Save Settings feature if you want to make them your default settings. The

factory defaults are as follows:

Operating Mode = Normal

Network Delay Time = 1 Second

Ring-Down Delay Time = 2 Seconds

Calling Part Control (CPC) = Enabled

Rotary/Pulse Dial = Enabled

311/E-911 Stutter Ring = Enabled

Quick Ring (ww) = Enabled

Recall Dial Tone/CLASS Mode = Enabled

Speaker Audio Mute = Enabled

Reorder Tone = Enabled

311/E-911 Record Beep = Enabled

INE

Telephone Line Simulator Page 9 December 2007

Save Settings (w4759w)

This code will store your settings in the unit’s memory. If you do not save the settings then any

feature changes that you have made will be discarded when power is lost. If the settings are

stored then they will be retained. Memory retention does not require a battery.

311/E-911 Stutter Ring (w4764w/ w4765w)

The special emergency phone numbers can be set to ring normally or use a stuttered ring. Calls

to “311" will provide a double bell stutter and the E-911 number will sound with a triple bell stutter.

You can turn off the bell stutter feature by dialing w4764wor turn it on by dialing w4765w.

Quick Ring Feature (w4766w/ w4767w)

You can use a shorthand method to ring the other line. The Quick Ring mode can be used by

dialing ww

wwww

ww (star-star) whenever you hear dial tone. If the CLASS mode is disabled only one w

wis

required. You can turn off the Quick Ring feature by dialing w4766wor turn it on by dialing

w4767w.

CLASS/Recall Tone Disable Feature (w4776w)

To disable the CLASS/Recall Dial Tone feature, obtain dial tone and dial w4776w. With the

CLASS mode disabled, the wcodes will be prevented from sending the three response beeps and

the codes will be ignored. Your LineMan can now start phone ringing with just a single wentry

(see Quick Ring feature). This feature cannot be saved as a default setting. To cancel it just dial

#whenever you hear dial tone.

Speaker Mute Disable/Enable (w4790w/ w4791w)

The optional external speaker audio can be attenuated (muted) approximately -3dB during DTMF

or call progress tone activity. The voice/data volume is not attenuated. The attenuation is limited

to the external speaker audio jack and does not affect the telephone line’s level. This attenuation

prevents the loud DTMF and dial tones from disturbing the listener. Code w4790wwill turn off the

Speaker Muting feature and code w4791wwill turn it on. We recommend that you leave the mute

feature enabled.

Re-Order Tone Control (w4796w/ w4797w)

If you dial an incomplete number, you will receive a reorder tone (fast busy). You can turn off the

reorder tone by dialing w4796wor turn it on by dialing w4797w.

311/E-911 Two-Way Record Beep (w4798w/ w4799w)

During a 311 or E-911 emergency call you will hear a beep noise every ten seconds. This short

tone is used to simulate the two-way record beep heard on monitored or recorded lines. This

provides a more realistic experience when LineMan is used as an E-911 training system. You can

turn off the record beep feature by dialing w4798wor turn it on by dialing w4799w.

LineMan Rear View

External Audio Jack

The rear panel mounted E

XTERNAL

UDIO

Jack can be used with an amplified speaker system.

This allows you to publically broadcast your phone conversations. This is ideal for sales

demonstrations, telephone training, and test monitoring. The audio connector is a standard 1/8"

miniature phone jack. It provides a buffered low level signal, so you must use an amplified

speaker (mono or stereo). The low cost speaker systems used with “PC” computer sound cards

work quite well.

High Loop Jumper

The rear panel mounted H

OOP

Jumper feature can be used to increase the telco loop current

by 25%. To increase the current, short the two pins with a standard .1" shorting block (available

at your local computer/electronic store). This feature should only be used with telephone

equipment that requires higher loop current. Normally the jumper is NOT installed, which provides

standard loop current.

Power Jack

LineMan must be connected to the provided AC wall adapter (transformer). For use outside North

America, a suitable AC adapter can be purchased from a local electronic parts supplier. The unit

requires 14VAC 50/60Hz at 500mA. The power jack will accept a 2.1mm x 5.5mm coaxial plug.

Please note that a “DC” adapter will NOT work, so be sure to use an “AC” output type.

Modular Jack Wiring Format

The modular jacks are wired in the RJ-14 format. The primary line is on the inside pair and the

secondary line is on the outside pair. This allows for the convenient use of 2-line telco devices.

If yours uses the secondary telephone leads for accessory control (A-leads, lamps, etc.) then you

will need to disconnect them from R
