AI-7280/AI-80 Specific:
1.  Display the delay from going off-hook (or line flash) to the start of the first dialed DTMF digit.  The delay time is displayed on the main control panel as well as the dialing logs.   
2.  Add a programmable delay time for the network tone (if any) configured to start once the TE goes off-hook.  Previously, the tone would start immediately following the off-hook.

AI-5120 Specific:
1.  Add a new setting in the 'FSK Detection Settings' window that optionally ignores FSK data in either the on-hook or off-hook state.
2.  Fix a bug that prevented (under certain situations) a display update if DTMF warning limits where changed.  The missing display update could have resulted in warnings being shown when they should not have been (or vice versa).
3.  Add the ability to configure the AI-5120 to record data without the TRsSim software connected.  For remote data collection, the AI-5120 can be configured to output event and waveform data directly to its USB or RS-232 port on power up.  If the data is recorded to a file (using 'Ai5120logger.exe' or other similar application), the event and waveform data can be recovered by the TRsSim software.
4.  Fix a bug introduced in vrs 1.31 that prevented the logging and exporting of event data.

4.  Add properties and functions to write and control low level device scripts.  

AI-7280/AI-80 Specific:
1.  Support Japanese NTT Type II CID.  A Caller ID signaling sequence is now included for generating Type II CID.  Note that only the AI-7280 can execute the Type II signaling sequence.
2.  Add a 41h message type for NTT CID.  The type 41h message is used for Type II NTT CID.  Messages can be set for auto-selection.  This changes the message type value between 40h and 41h depending if a Type I or Type II CID is being sent.
3.  Add new NTT CID message parameter 'Calling Number Extended Information'.
4.  In 'Signal Analysis & Generation' mode, add a new action that generates back to back line reversals.
5.  In 'Signal Analysis & Generation' mode, add the ability to write short scripts that execute directly on the AI-80 or AI-7280.
6.  For the AI-7280, use a band pass filter when measuring the SMS FSK message levels.  This fixes a problem where DC voltage shifts (line reversals or such) close to FSK messages upset the level meter to such a large degree that timing measurement accuracy becomes poor.  The band pass filter helps to removes the effect of large DC voltage shifts.
7.  Fixed a bug causing a terminal error if more than 25 Caller ID signaling blocks where inserted into a sequence.
8.  Display Type II Caller ID 'extension-in-use' check timing information in the Data Viewer window.  In addition, the ACK start and stop times can be shown when using the AI-7280 (not supported with the AI-80).

10.  For parameter sweep graphs, limit the minimum vertical span to 1 dB.
11.  Add a new setting for signal generator termination impedance of 'Source Z'.  This setting assumes the line termination impedance will be exactly the same as the line source impedance setting.
12.  Fixed a bug that occured when deleting CID signaling elements that have a branch.  If the lower portion was deleted, the branch element above was not correctly modified to reflect the change.
13.  Fixed a bug that caused the TRsSim software to try to generate a Type I CID (on-hook), when the line state was off-hook.  This occurred when the 'Reset.All' function was used in a script program and the current line state was off-hook.

AI-5120 Specific:
1.  If only a single AI-5120 is connected, default to a new display view.  The 'Docked Window' mode automatically opens two linked Data Viewer windows that automatically display a list of detected events in one window and the captured waveforms in the second window.  The windows are automatically resized to the application window size.  This display mode can be enabled or disabled from a command selection under the 'Window' menu.
2.  Modified CID Summary report view as follows:
  a)  Lock header to the top of the window.
  b)  Scroll bar position is not reset when selecting different CID transmissions.
  c)  Ensure waveform icon is refreshed in case the waveform download does
       finish until after the display updates.
  d)  Add a waveform icon that displays the entire CID transmission (all elements).
  e)  If in 'docked window mode', the CID waveforms are displayed in the 2nd
       window.  
3.  For the FSK waveform analysis, fixed a distortion measurement error that occurred when the mark level and frequency could not be measured.  In such a case, a warning message is included in the report.
4.  Fixed a bug that could cause an extra channel seizure bit being reported (for FSK messages).
5.  For the event list view, add an option to always 'snap to last' event.  If enabled, once additional events are detected, the Data Viewer window always ensures they are displayed.
6.  Add two tool bar buttons to snap to the next or previous waveforms.  When clicked a search is made for the next or previous waveform and if found, the waveform(s) are displayed.
7.  Changes to the Navigation bar:
  a)  Hovering the mouse over a waveform displays a pop-up of the waveforms.
  b)  Left clicking on any waveform causes that waveform to be displayed.
  c)  Right clicking enters a local panning mode.  Hold the mouse button down
       and drag left or right to pan over a range 10 times the currently displayed
       time span.
8.  Fixed bug when time shifting waveforms via cursor positions.  The time delta was incorrectly calculated as B-A instead of A-B.
9.  Add two additional cursor commands to move either cursor A or cursor B to the screen center.
10.  Coping and moving waveforms.  A new 'Copy & Float' menu command makes a copy of a selected waveform and floats it on the screen.  As the time scale is panned, the floating waveform does not move.  To move the floating waveform, click on the center screen icons to move vertically, horizontally, or in both axis together.  To fix the floating waveform in time and vertical position, select the 'Lock Position' command under the Waveform menu.
11.  To toggle the event detection and waveform capture enable, click the mouse on the green/red light icon on the main window.  This is a shortcut to clicking the 'More' button and selecting 'Freeze/Resume Detection & Recording'.
12.  If more than 5000 events are detected, the 'Event Find' window can display them in groups of 5000 by using the drop-down list box at the bottom of the window.
13.  The redraw speed of the event list has been greatly increased.  Scrolling now occurs at a much faster rate.
14.  Complex event searches can be created.  Searches can specify multiple events with various logical relationships.  In addition, criteria can be added to event  measurements.  To define searches, select the 'Event Search Criteria' from the 'Settings' menu.  Once searches are defined, the results can be viewed by selecting 'Search Results' from the 'View' menu.
15.  Add the option to measure THD+N from the main window level meter.  It is enabled by selecting 'Measure THD+N' when the units button is clicked.  Once enabled, the AI-5120 automatically tunes its notch filter to the strongest signal in the range of 80 to 10000 Hz.
16.  For the AC Signal event, add two detection modes.  They are minimum level, and minimum level with frequency.  
17.  If the waveform analysis optional component is enabled, then waveform captures due to AC Signal events will cause an automatic measurement to be made of the signal's frequency and level.  These measurements are annotated on the waveform display and shown in the event list.  In addition, the measurements may be exported or logged to a file.
18.  Add the option to export waveforms at different sample rates.

AI-7280/AI-80 Specific:
1.  For ETSI Protocol 1 SMS, the Message Generator window now supports the usage of 16 bit reference numbers when concatenating long messages.
2.  For ETSI Protocol 1 SMS, allow alpha-numeric addresses. If the type field is set to a value between D0h and DFh, the address is encoded using the GSM 7-bit character set. If any other type value is used, the address is encoded as semi-octets.
3.  Add an option in the Caller ID Signal Settings window that adjusts the time reference point for ACK detection to the end of the ACK signal. By default, the time reference point is the moment the ACK signal is detected. Note, this setting is only applicable when using the AI-7280.

AI-5120 Specific:
1.  Increases the maximum number of frequencies in a network tone to four and allows a wider frequency range from 300 Hz to 5000 Hz. Note that a single tone frequency between 800 and 1180 Hz can not be detected. Requires AI-5120 firmware version of 2.01 or greater.

3.  Add "auto-increment" support for FSK based Caller ID parameter.
4.  Add FSK based Caller ID message type and length offset fields.
5.  Add ETSI SMS protocol 2 message generator window.  Similar to what exists for protocol 1, this window simplifies the task of generating segmented TL messages.

Add right mouse click popup menu with view history and moving to next/previous events & waveforms. Panning mode entered by clicking new mode button, middle mouse click, or right mouse click AND CTRL button held. When in panning mode, automatically scroll when mouse is moved off the view port. When scrolling left or right and no waveform data exists at the current view, snap to the next/previous waveform based on the scroll direction. 
9.  Be able to specify the analysis range for all waveform analysis types (instead of just DTMF). Now FSK/CAS/DTMF/NT analysis can be performed over a variable range.
10.  Add a new event type for network tone.  Common network tones such as dial, ring back, and busy can now be detected.  Custom templates from 1 to 3 tones can be specified.  Requires AI-5120 firmware version 2.00 or greater along with the TRsSim Waveform Analysis option.
11.  Add an option for adjustable high pass and low pass filters to be engaged during any waveform analysis type.

General:
1.  Support a compressed file format for configuration files (.cfz) and script project files (.spz).  The older uncompressed file format remains supported, however using the compressed format greatly reduces the file size.  When using the AI-5120, the waveform capture file is now included within the compressed file.  A separate capture file (.cap) is no longer produced.
2.  Setup package includes an updated USB driver (version 1.6.20).  

AI-7280/AI-80 Specific:
1.  Bug fix. The DLE character codes within a NTT Caller ID message were not treated correctly.  They should of been automatically duplicated within the message contents.

3.  Add two Signal I/O options to mute either the BNC audio input or BNC audio output connectors during a Type II (off-hook) Caller ID transmission (AI-7280 only).
4.  Stop performing local syntax checks for USER blocks in the CID signaling sequence. The syntax check prevents using globally defined variables in the USER block, since they are defined elsewhere in the CID signaling program.
5.  Improve response time for terminating network tones when a DTMF digit is dialed (assuming this option is enabled).  The network (dial) tone is now normally terminated before the first DTMF digit finishes.
6.  Support user defined wave shapes for ringing (AI-7280 only).

AI-5120 Specific:
1.  DTMF detection and analysis modifications: 1) lower minimum detect level to -35 dBV, 2) improved ability to detect DTMF in the presence of other tones (ie. dial tone).  Note, requires AI-5120 firmware of 1.05 or greater.

Scripting:
1.  Double clicking a module in the project view window displays the source code module.
2.  Add "Save Project" menu command to complement the existing "Save As Project" menu command.
3.  Add "Immediate" window (under the "Run" menu). Script commands entered into this window are directly executed. They run in parallel with any other script program execution.
4.  Script modules can be linked to external files. This allows other editors to be used with script projects. To link a file to a module, right click the mouse on the module in the "Script Project" window, and select the "Link to File..." command.
5.  Expand script editor help list capabilities to: i) Show all help items, ii) Find modules or declarations for subs/functions/variables/constants/labels, iii) search help list for keywords, iv) disable help list when using slower PCs.

2.  Add Cid.Messages.Fsk.Script.AddLine property and Cid.Messages.MDMF.Param.Custom function (allows user defined parameters).
3.  Add Sms.Events.Flags property.   This read only property returns 1 for Rx/Tx phantom message events (if Rx message ignored by SM-SC, or Tx message sent with zero FSK level).
4.  Add Reset() functions.  Used to return various program settings to their default values.
5.  Add ability to show a user definable list of items from the pop-up message window.  See PopUpMsg.List properties and functions in the help file.

AI-7280/AI-80 Specific:
1.  Change all default Caller ID signaling sequences to generate only a single ring following the FSK/DTMF transmission.
2.  For ETSI protocol 2 SMS setups, event definition now supports phantom message transmission (SC sends message with zero FSK level), and ignoring Rx messages (SC ignores the message from the TE). Both of these event options help to simulate event sequences where messages are not received properly (on either side). Sending phantom messages still updates applicable timers, while ignoring Rx messages does not reset, start, or stop any applicable timers.
3.  Bug fix for AI-7280 FSK decoder filter delay nodes.  Fixes a problem that can cause the unit to miss the first FSK message after power up.
4.  Add new "custom" Caller ID MDMF parameter type. Allows user defined type, length, and data bytes. This can be used to test unknown or illegal parameters.  Requires Advanced Caller ID option.
5.  For Telecordia Caller ID type, use the same set of available MDMF parameters for both the Call Setup (80h) and VMWI (82h) message types.    Requires Advanced Caller ID option.
