Telephone Line Emulator User’s Manual

Basic Calling Operation

The Teltone TLE provides dial tone (Normal – default), or Ringdown (Hotline), or a quiet battery feed (Silent), when a device goes off-hook and draws sufficient loop current. When dialing is detected, DTMF or Pulse (aka Rotary dialing), dial tone stops. If an invalid sequence is dialed, the TLE will issue an Invalid Number Response of SIT + Audio (default), SIT repeating, Busy, Reorder, Ringback, Silence, or Audio. If a valid number is dialed, a Hunt Mode of Ring All (default), Ring 1st match, Ring 1st available, or Ring next, is invoked. Caller ID information is sent to the Called Party, along with Ringing, and Ringback tone is sent to the Calling Party. When the called line answers, a connection is established between the two parties.

During an existing call, another party may go off-hook and dial a number that matches one of the connected parties. If so, then a SAS (Call Waiting tone) + CAS (Caller ID tone) is issued to the called party. If the called party has a Caller ID box or phone that supports SCWID (aka Caller ID in Call Waiting), then the Caller ID information will be issued by the TLE. If the called party does not answer the waiting call, a repeat of the Call Waiting tone occurs ten seconds after the first. During an existing call, either party may wish to Transfer/Conference another party. To accomplish this, the originating party must generate a hook flash, after which the TLE will return a Confirmation Dial Tone, and the originating party will dial the number of a third party. After connecting to the third party, all three are brought together with another hook flash. Conference operation is dependent upon the setting of the Conference Type in the Miscellaneous Screen.

The end of a call uses Calling Party Control. If the Called Party hangs up, the connection may be re-established if they go off-hook before the Forced Disconnect Timer expires. If the Calling Party goes on-hook, or if the Forced Disconnect Timer expires, then a Forced Disconnect signal, a break in the loop current, is sent to the remaining party if they are offhook. After a Forced Disconnect signal is sent, and the party remains off-hook, then Disconnect Treatment is invoked. The options include Dial Tone (default), Busy, Reorder, Silence, or an Audio message.

The TLE supports a few special dialing sequences. These include: Special Caller ID dial ∗67 + telephone number to send PRIVATE dial ∗87 + telephone number to send OUT OF AREA dial ∗88 + telephone number to send Checksum error Speed Dialing dial 1#, 2#, 3#, or 4# to access lines 1,2,3, or 4 respectively Visual Message Waiting dial ∗50 + telephone number to turn VMW ON dial ∗51 + telephone number to turn VMW OFF DTMF Programming dial ∗∗99## Set Active Configuration dial ∗xx#, where xx is the configuration # Version Query dial ∗99#, view display for versions

Special Telephone Numbers (programmable) include: Audio Access Message dial 411 Dial Tone (continuous) 83781 (TEST1) Busy (continuous) 83782 (TEST2) Reorder (continuous) 83783 (TEST3) Ringback (continuous) 83784 (TEST4) Special Test Tone (continuous) 83785 (TEST5) Stuttered Dial Tone (continuous) 83786 (TEST6)

Telephone Line Emulator User’s Manual

Configuring the TLE

Using the Configuration Software, different configurations can be saved to download to the TLE. A configuration contains all the programmable parameters of the TLE. The standard TLE (TLE-BASE) unit can have 2 different configurations, while the add-on software modules can have up to 16 different configurations.

The Active Configuration is the configuration that is being used by the TLE. Any configuration may be selected as the Active Configuration using the Configuration Software, or an ASCII command string via the serial port, or a DTMF dialing sequence from a device connected to a port. See below for more information.

A Configuration Set is a file name given to reference the configurations saved. Only one Configuration Set can be downloaded to the TLE, although multiple Configuration Sets can be saved on the PC.

Editing a configuration may be done off-line, or while connected to the TLE. While connected to the TLE, changes made are updated in the TLE by either selecting the APPLY or OK button on each screen. Using the APPLY button will implement the changes but keep the current screen to allow for any additional changes. Using the OK button will implement the changes, exit the screen and return to the Main screen. If the update is to the Active Configuration, every update will cause the display of the TLE to show “Initializing Configuration” and then “Active Configuration” and then the configuration number. The TLE must be in the idle state (all lines on-hook) for the update to occur. If the update is to a configuration that is not currently active, the TLE display will not change.

When the TLE_PC software is run, it will read the Unit Name and the Active Configuration of the TLE and display them on the Main screen of the software. If there is no TLE connected, the title bar will read TLE_PC - No Unit Connected. If there is a TLE connected and the Configuration of the TLE does not match the default configurations in the software, a screen will appear asking whether you want to query the TLE for its configuration settings. In addition, any time the TLE is initially connected, the software will automatically query the unit for firmware version information. If the software has an updated version, it will ask you if you want to download the new code.

Reset

On the front panel of the TLE there is a recessed button called Reset. Pressing this button for greater than 1 second once will display a prompt asking. “Reset all configs? Press Reset = yes”. Pressing Reset a second time for greater than 1 second will reset the TLE configuration memory to the factory default settings with Configuration 1 active.

When the front panel Reset button is pressed, the unit will be reset to the US/Canada defaults for all configurations. The user must perform Defaults and Send All from the PC configuration software to reload the defaults for each individual country configuration.

Selecting Active Configuration using DTMF

All other ports must be on-hook and the dialing sequence is as follow: go off-hook, dial ∗∗99## to enter Programming Mode, then dial ∗xx#, where xx is the configuration number. For example, to select configuration 02, dial ∗02# and the TLE will respond with

40-400-00020, Rev. M 10

Telephone Line Emulator User’s Manual

a three beep confirmation tone (if enabled), and the display will show the new configuration following an initialization sequence. If an error in the entry occurs, the TLE will respond with a single beep error response.

Selecting Active Configuration using the serial port

The Active Configuration may be selected via the serial port with PC_TLE software 2.00 or greater. This is accomplished by setting up the serial port at 9600 baud, 8 data bits, 1 stop bit, no parity, hardware flow control, and sending an ASCII string to change the Active Configuration. The format of the message to the TLE is either:

:XX<cr> or,

:XX,YY<cr>

The TLE will respond with !OK if the command is accepted or !ERR if it is rejected.

:XX will set the active configuration from 01 to 16 for all 4 ports and :XX,YY will set the active configuration XX for ports 1 and 3 and YY for ports 2 and 4.

Note: Local echo of command characters is not provided by the TLE.

Main TLE Screen

The top section of the main TLE screen displays the Active Configuration Number, Name, and Date/Time it was created, if a TLE is connected. This field will be blank if no TLE is connected. It also shows the current Configuration Set Name and the Date/Time it was created. The Set Active button allows the user to choose the Active Configuration in the TLE.

The middle section of the screen displays the Configuration being edited. The Name button allows the user to change the name of each configuration. The Send button sends the current configuration being edited to the TLE. The Send All button sends all of the

40-400-00020, Rev. M

Figure 5. Main TLE Screen (No TLE Connected)

Telephone Line Emulator User’s Manual

configurations in the Configuration Set to the TLE. The Query button will query the settings for the current configuration in the TLE. The Query All button will query all of the stored configurations in the TLE. The Defaults button will reset any Configuration under edit to the factory default settings.

The bottom section displays buttons that conform to the natural order of call placement and pressing any of these buttons will bring up windows with information regarding the operation of the TLE. Another method to use when changing the operation of the TLE is to use the S alphabetical order. A Find button is also supplied to help with locating the parameter to be changed.

The bottom line of the Main screen will report three items:

1) The name of the saved file under edit.

2) If the Configuration Set under edit matches what is stored in the TLE, Set=TLE will be

displayed. If the Configuration Set does not match, Set<>TLE will be displayed.

3) If the Configuration being edited matches the configuration stored in the TLE,

Configuration=TLE will be displayed. If not, then Configuration<>TLE will be displayed.

The S These are broken into individual screens labeled as Audio, Busy, Call Waiting, Caller

ID, DC Signaling, Dial Tone, Loop Parameters, Miscellaneous, Phone Numbers, Port Configuration, Reorder, Ringing, Special Information Tones, and Voice Messages.

Other screens that are active if the TLE-INTL, TLE-ADV, or TLE-TEST software modules are purchased include Country, Metering Tones, Impairments, Signal Level Measurement, and Automated Test. The TLE-ICID Software Module combines Call Waiting and Caller ID into a single screen called Caller ID/Call Waiting.

Operational Screens

Audio Line Monitor

The Audio port on the front of the TLE is used to monitor the AC signals on any one of the lines of the TLE when this feature is enabled. Only one line may be monitored at a time. The audio line monitor port is a 3.5 mm miniature audio jack.

Figure 8. Audio Screen

Recorded Messages

The Recorded Messages portion of the Audio screen, together with the Voice Messages screen, allows the selection of recorded messages for playback. There are three conditions defined for playback: Invalid phone Number dialed, Audio message on Disconnect, and message for Dial Access. There are four

messages which may be stored. The default names (see Voice Messages screen) are: Invalid Number, Disconnect, Dial Access, and Alternate. Any of these four names may be selected for the three conditions with the Audio screen.

When one of the conditions for playback occurs, the recorded message plays one time, followed by silence. If the Repeat selection is checked, the audio message will repeat continuously.

The TLE ships with one default message for each of the three conditions. These messages are stored in a mono 8 kHz, 8-bit µ-law WAV file format. Their names are: Invalid.WAV, Hangup.WAV, and Dialacc.WAV. The user may create new files using a sound card. Double clicking on the File field in the Voice Messages screen allows the selection of a new file. The TLE-PC software stores these in

0.5 seconds increments and displays the total file length on the screen. The sum

40-400-00020, Rev. M 14

Telephone Line Emulator User’s Manual

of all recorded messages must not exceed the total length for the audio memory (8 seconds).

Attenuation

Attenuation is the loss of signal level. Attenuation values refer to the amount of attenuation compared to the original recording.

Attenuation may be set from 0 dB to 60 dB in 1 dB increments.

Busy Tone

The Busy signal is an indication that the Called Line is off-hook and not available. Busy Tone has several variables, including: single tone or dual tone, output level, and a simple or complex cadence.

Figure 9. Busy Screen

Busy Tone Levels and Frequencies

Busy Tones may be single or dual frequencies with individually adjustable amplitudes. With a selection of Single Tone the system will only generate the first tone. With a selection of Tone 1 + Tone 2 the system will generate both tones with the specified frequencies and amplitudes. Purchase of the TLE-INTL Software Module adds the selection of Tone 1 x Tone 2. The system will generate Tone 1 modulation by Tone 2. In this implementation only the fundamental and upper side tone are generated, both at the amplitude programmed for Tone 1.

For each tone, the frequency range may be set from 10 Hz to 1000 Hz in 1 Hz increments.

Output level may be set from -6 dBm to -60 dBm per tone in 1dB increments.

Busy Tone Cadence

First Cadence on time may be set from 100 mS to 2000 mS in 5 mS increments.

First Cadence off time may be set from 100 mS to 2000 mS in 5 mS increments.

40-400-00020, Rev. M

Telephone Line Emulator User’s Manual

Second Cadence on or off time may be set from 0 mS to 5000 mS in 5 mS increments, or

may be set to 0 if only the First Cadence values are to be utilized.

If the Second Cadence values are 0, the unit will repeat with the First Cadence values. If the Second Cadence values are programmed, the unit will repeat after going through all four time values.

Call Waiting

The Call Waiting signal (a.k.a. SAS Tone, Subscriber Alerting Sequence) is an indication that there is a calling party waiting for the called party to become available. The calling party hears normal ringing and the called party hears a Call Waiting Tone that is repeated once, 10 seconds after the first occurrence. The called party answers a Call Waiting by either generating a FLASH, which places the existing caller on hold, or by hanging up on the existing caller, after which the telephone will begin to ring again with the waiting caller. In some Central Offices, a waiting caller is announced with a Normal single tone if the call is local, and a Distinctive two tone sequence if the caller is calling from long distance.

Call Waiting With Caller ID Enabled (SCWID or CIDCW)

SCWID (Spontaneous Call Waiting with Caller ID) also known as CIDCW (Caller ID in Call Waiting) is a function that sends the FSK data (Caller ID) after a Call Waiting Tone. This data transmission burst is typically sent to a specially configured telephone or an adjunct device that mutes the line to the local caller for the duration of the FSK burst. The format of the message is always multiple message format, that is, the Name and Number are sent to the called party. This feature is invoked whenever a third party places a call to an existing call, if Caller ID is enabled and Cancel Call Waiting has not been enabled. When a third party is calling, the called line will be momentarily isolated and will hear a Call Waiting Tone (SAS tone), followed by a CAS tone to alert the Caller ID phone or adjunct. If the Caller ID phone or adjunct issues a DTMF “D” (from non-ADSI CPE) or a DTMF “A” (from ADSI CPE) acknowledgement tone, the FSK sequence is sent down the line for Caller Identification. The called party may then ignore the Call Waiting, or generate a flash to place the first caller on hold, and answer the Call Waiting. If the Called Party ignores the first Call Waiting alerting sequence, it will be repeated once, ten seconds later. If the called party answers the Call Waiting, they are allowed to alternate between callers using the flash function. If one party hangs up, the remaining parties are automatically connected.

Call Waiting with Caller ID Disabled

A user may want to have the TLE generate just the Call Waiting Tone (SAS tone) without Caller ID or CAS tone. To have the TLE perform in this manner, go to the Caller ID Screen and disable Caller ID for the line in use.

Cancel Call Waiting

The Call Waiting tone may be disabled on a per-call basis by dialing ∗70 or 70#, TLE Response - Confirmation Dial Tone. (See Dial Tone screen.) Call Waiting will be reset and enabled after the line is placed on-hook.

Telephone Line Emulator User’s Manual

Figure 10. Call Waiting Screen

The Call Waiting signal has several variables, including: Disabled, Single Tone or Dual Tone, Type of Call Waiting Signal, and Cadence.

Call Waiting Tone Levels and Frequencies

Call Waiting Tones may be single or dual frequencies with individually adjustable amplitudes. With a selection of Single Tone the system will only generate the first tone. With a selection of Tone 1 + Tone 2 the system will generate both tones with the specified frequencies and amplitudes. Purchase of the International Module adds the selection of Tone 1 x Tone 2. The system will generate Tone 1 modulation by Tone 2. In this implementation only the fundamental and upper side tone are generated, both at the amplitude programmed for Tone 1.

For each tone, the frequency range may be set from 10 Hz to 1800 Hz in 1 Hz increments.

Output Level may be set from -6 dBm to -60 dBm per tone in 1 dB increments.

Call Waiting Type

Call Waiting Type may be programmed for each Line. Options are Disabled, Normal, and Normal & Distinctive.

Call Waiting Cadence

Two Cadences are available: Normal and Distinctive.

Both Cadence on times may be set from 0 mS to 1500 mS in 5 mS increments.

Cadence off time may be set from 0 mS to 1500 mS in 5 mS increments.

Leading Blank, or the delay before the call waiting tone is sent, may be set from 5 to 100

mS off in 5 mS increments. (Default = 50 mS.)

40-400-00020, Rev. M

Telephone Line Emulator User’s Manual

Trailing Blank, or the delay after the call waiting tone is sent, may be set from 20 mS to

100 mS off in 5 mS increments.

The Leading Blank time is the time from when the existing call is muted and the Call Waiting starts. The Trailing Blank time is the time from when the Call Waiting stops and the existing call is reconnected.

Caller ID - Visual Message Waiting

The Caller ID signal is an FSK signal sent at 1200 baud to alert the called party of the identity of the calling party. This may consist of the telephone number only, (Single Message Format), or a Name and Number (Multiple Message Format). The transmission also includes a Date and Time, and issues a checksum at the end for error correction. Special sequences include Out of Area ∗87 (indicates no available information for the caller), Private ∗67 (Blocked Call) and an error message ∗88 (checksum error) when a special prefix code is dialed before the normal telephone number. For testing and development purposes, there is a special mode where the Caller ID is sent after every ring. (TLE-ADV only.)

Visual Message Waiting is an FSK signal sent at 1200 baud to turn on a visual indicator on an adjunct or Caller ID phone. This signal is sent during an on-hook state after an open switch interval.

Turn ON the Visual Message Waiting Indicator using the following dial sequence;

Dial ∗50 + “Called Telephone Number”

Turn OFF the Visual Message Waiting Indicator using the following dial sequence;

Dial ∗51 + “Called Telephone Number”

Example: A Caller ID adjunct or display phone is connected to Line 2. From a telephone connected

to any other line, go off-hook and dial *50 102. The display for the called line will indicate VMW sent during the time when FSK is generated after the Open Switch Interval.

Stuttered Dial Tone is issued to the called line until VMWI OFF is invoked or the Dial Access Audio Message is dialed. Default is 411.

Note: The TLE-ICID Software Module is available as an upgrade to the TLE-INTL Software

Module. This upgrade module combines the Call Waiting screen and the Caller ID screen. The TLE-INTL software will allow Caller ID to be enabled for other countries but it conforms to the Bellcore (USA/Canada) standards.

Caller ID Time

This may be set either by the user or can be read from the PC clock. The TLE maintains a real time clock only when power is on. Upon power up the date and time start at the time as set by this field.

Caller ID After Every Ring

Caller ID After Every Ring is a feature that will send the FSK sequence after every

Power Ring Cycle. The Caller ID will be sent only if the minimum off time criteria is met. (TLE-ADV and TLE-TEST Software Modules only.)

Minimum Ring Off Time

By default, the TLE must see a minimum of 3 seconds in the off portion of the Ring Cadence, before Caller ID is sent. By programming this field to a shorter time, the user can force a transmission during shorter Ring Off Time. The user must be aware that, for shorter times, the entire FSK data burst may not be complete before the next ring cycle.

The Minimum Ring Off Time can be set from 0 seconds to 10 seconds in 5 mS increments. Default is 3 seconds.

Caller ID Sequence

Caller ID Sequence is a feature that allows a user to select the sequence and information

that is sent with each Caller ID block using the Multiple Message Format. This is useful to ensure that CPE devices may receive this data regardless of the order of the messages.

If a ∗67 prefix is dialed prior to the number, the Private sequence will be used.

If a ∗87 prefix is dialed prior to the number, the Out of Area sequence will be used.

If a ∗88 prefix is dialed prior to the number a checksum error is generated.

Otherwise, the Normal sequence will be used.

Caller ID Mode

This feature allows the selection of the Caller ID Mode for each Line. The options include Multiple Message format (default), Single Message format, or Disabled.

Select Name & Number

This feature allows the selection of one of three different Groups of Names and Numbers (see Phone Numbers). The Names for Group 1 are programmable for up to 16 characters. The Names for Group 2 and 3 are fixed. The defaults for the Names follow this paragraph.

Group 1 - Programmable names, uses Group 1 telephone numbers Line 1 = ANDERSON ALLEN Line 2 = JONES JENNIFER Line 3 = SMITH SHARON Line 4 = MACDONALD MIKE

Fixed names for Group 2, uses Group 2 telephone numbers Line 1 = CLINTON BOB Line 2 = REAGAN RICK Line 3 = CARTER JOHNNY Line 4 = FORD GARY

Fixed names for Group 3, uses Group 3 telephone numbers Line 1 = MONTANA JIM Line 2 = MARINO DON Line 3 = AIKMAN TOM Line 4 = KELLY JOHN

Group 1 Name

The Group 1 Name is programmable up to 16 characters. This is the name that is sent to the Called Line from the Calling Line when Multiple Message format is used.

Visual Message Mode

This feature allows the selection of the Visual Message Mode for each Line. The options include Multiple Message format (default), Single Message format, or Disabled.

CAS Tone

CAS Tone is a CPE Alerting Signal; a Bellcore term for a tone used to alert CPE equipment of Call Waiting, asking for ACKnowledgement prior to sending Caller ID. The CAS Tone has several variables, including: Disabled, Single Tone or Dual Tone, Duration, and Time to Wait for Acknowledgement.

With a selection of Single Tone the system will only generate the first tone. With a selection of Tone 1 + Tone 2 the system will generate both tones with the specified frequencies and amplitudes. Purchase of the International Module adds the selection of Tone 1 x Tone 2. The system will generate Tone 1 modulation by Tone 2. In this implementation only the fundamental and upper side tone are generated, both at the amplitude programmed for Tone 1.

Frequency for Tone 1 and Tone 2 may be set from 10 Hz to 3000 Hz in 1 Hz increments and -6 dBm to -60 dBm in 1 dBm increments.

Duration may be set from 70 mS to 90 mS in 5 mS increments.

After the TLE sends the CAS signal it waits a certain time for a DTMF ACKnowledgement signal from the CPE device. If it sees this, it sends the FSK data. This Wait for Acknowledgement time may be varied to ensure that CPE devices are responding within the proper time window. Wait for Acknowledgement may be set from 100 mS to 300 mS in 5 mS increments.

FSK Tone

The FSK (Frequency Shift Key) Tones are programmable in both frequency and signal level. The mark (1) tone is the lower of the two tones and is programmable from 1100 Hz to 1400 Hz. The space (0) tone is the upper tone and is programmable from 2000 Hz to 2300 Hz. Both tone levels may be set from -10 dBm to -60 dBm in 1 dB increments.

40-400-00020, Rev. M

Telephone Line Emulator User’s Manual

Open Switch Interval

The Open Switch Interval is a form of DC signaling, sent during an on-hook state, prior to Visual Message Waiting. During this time, the -48 VDC is momentarily removed. Open

Switch Interval may be set from 0 seconds to 5 seconds in 5 mS increments.

Advanced Screen Telephony

ADSI, also known as Advanced Screen Telephony, a Type III Caller ID sequence, is supported in the TLE using a special ADSI test number ∗∗99∗∗, which performs a script download from the TLE. Three data bursts are sent from the TLE, shown in the display as ADSI_ack1, ADSI_ack2, and ADSI_ack3 to load a script called “Call Management”.

This new service provides a limited script that will display “New Call From” and “Caller ID”. After answer, the display changes to “Talking To” and “Caller ID” and a button labeled “Don’t interrupt”. If the button is pressed, the CPE will perform a flash; dial ∗70 to disable Call Waiting and then displays “Call Waiting OFF”.

When the CPE receives a Caller ID during a call, the display will show “New Call From” and “Caller ID”. The button selection will change to “Connect New Call”. If this button is pressed, the original caller is placed “On Hold” and the button changes to “Reconnect

1st Call”.

DC Signaling

DC Signaling changes polarity or loop current characteristics of the line. These include

On/Off-Hook Detect Times, Hook Flash Detect Time, Line Reversal, and Forced Disconnect Length and Delay.

40-400-00020, Rev. M 22

Figure 13. DC Signaling Screen

Telephone Line Emulator User’s Manual

On/Off-hook Detect Times

Off-hook Detect is the minimum duration that loop current must occur for a valid off-hook condition. On-hook Detect is broken into two values. If a call has not been completed, for example a busy number has been dialed, a short on-hook time is used. If a call has been completed, a long on-hook time is used. This allows hook flashes to be recognized. If hook flashes have been disabled, the TLE always uses the Call Not Completed timer value for on-hook detection.

Off-hook Detect Times may be set from 100 to 3000 mS in 5 mS increments. On-hook Detect may be set from 100 to 3000 mS in 5 mS increments.

Note: On-hook time must exceed Hook Flash time.

Hook Flash Detect

Hook Flash, a.k.a. FLASH and Switch Hook Flash, is a loss of loop current for a specific duration that is used to request special features, such as Transfer, Conference, and Hold.

Hook Flash Detect Minimum and Maximum can be set from 75 mS to 1200 mS in 5 mS increments.

Each line may be enabled or disabled for Hook Flash Detect.

Line Reversal

A line reversal is a signal that changes the polarity of the battery on the line subject to certain conditions. These conditions may include Called Party Answer, Call Termination, and others. Line Reversal Type is available as Disabled, Simple or Complex. (The default is reversal disabled. This programming will apply to all lines.) When the unit is programmed for Simple Line Reversal on an originating call, a line will perform a reversal just prior to issuing dial tone. It will then remain at that state until it goes back on-hook, in which case another reversal will be performed. For an incoming call a line will perform a line reversal after it goes off-hook in response to ringing.

When the unit is programmed for Complex Line Reversal on an originating call, a line will perform a momentary reversal just prior to issuing dial tone. The duration of the reversal is programmable, and may range from 50 mS to 100 mS in 5 mS increments. On an incoming and outgoing call a permanent line reversal will be performed at call completion.

Forced Disconnect

Forced Disconnect is a method used by the telephone company to clear a line. When the called party goes on-hook, the Central Office returns an open (that is, drops loop current) of at least 800 mS to the calling party. The TLE emulates Calling Party Control, in which, if the calling party goes on-hook the called party receives a Forced Disconnect within 2 seconds. If the called party goes on-hook, the calling party receives a Forced Disconnect which may occur some time greater than 2 seconds later. This timer is programmable, up to 30 seconds. The actual Length of the Forced Disconnect is also programmable with the default being 850 mS.

Forced Disconnect Length may be set from 0 to 2 seconds in 5 mS increments.

Forced Disconnect Delay may be set from 1.2 to 30 seconds in 5 mS increments.

This feature may be enabled or disabled for each line.

40-400-00020, Rev. M

Telephone Line Emulator User’s Manual

Dial Tone

Dial Tone is the audible signal issued to a calling party when the Central Office is ready to receive digits. The TLE issues a Second Dial Tone after a series of digits are dialed to emulate operation of a PABX or other switch platforms. (See Revert to Dial Tone phone number.) Other types of dial tones include Recall Dial Tone (an interrupted Dial Tone, a.k.a. Stuttered Dial Tone, indicating recognition of a FLASH Hook to access other features), Message Waiting Dial Tone (an off-hook interrupted Dial Tone indicating messages in voice mail), and Confirmation Dial Tone (an interrupted dial tone sequence indicating that a feature has been properly used, such as Cancel Call Waiting).

Figure 14. Dial Tone Screen

Dial Tone Level and Frequencies

Dial Tones may be single or dual frequencies with individually adjustable amplitudes. With a selection of Single Tone the system will only generate the first tone. With a selection of Tone 1 + Tone 2 the system will generate both tones with the specified frequencies and amplitudes. Purchase of the International Module adds the selection of Tone 1 x Tone 2. The system will generate Tone 1 modulation by Tone 2. In this implementation only the fundamental and upper side tone are generated, both at the amplitude programmed for Tone 1.

Frequency for both tones may be set from 10 Hz to 1000 Hz in 1 Hz increments and signal level from -06 dBm to -60 dBm in 1 dB increments.

Dial Tone Cadences

The TLE supports multiple dial tones. These include Normal, Recall, Message Waiting, and Confirmation dial tones. Each dial tone may be configured for continuous, simple or complex cadence.

Simple cadence has one on and one off time. Default is 0.1 seconds on, 0.1 seconds off. Complex cadence has two separate on/off times. Default is 0.1 seconds on, 0.1 seconds
