  DSX System Software 3.45 Overview
  New Features and Enhancements


E911 simplifies 911 emergency call dialing. When E911 is enabled, a user can go to any telephone, lift the handset, and dial 911 without first dialing an access code or pressing any additional keys.

E911 alerts keyset users when someone has placed an emergency call. Keysets with E911 alerts enabled show a message on display line 1 identifying the 911 caller and play an optional audible alarm. The display remains until it is cleared and the audible alarm continues to sound until it is cleared or times out. The extension user can press CLEAR to immediately silence the alarm, then press CLEAR again to clear the display.

Before setting up E911, carefully review one of the following:

Important! Due to the flexibility inherent in the system, other features can interact with dialing 911. Review the DSX E911 Manual for specific feature interactions. Additionally, always test the system to be sure it meets the requirements for 911 accessibility.

Home Automation

Home Automation in DSX software version 3.45 features several important enhancements.

X10 Speed Up

The response time between connected X10 devices and DSX telephone control key presses has been improved. The first key press is immediately sent to the X10 device with additional presses buffered until user adjustment is complete.

Power Control Timer

With a Super Display Telephone, power devices (such as lights and switches) can now be timed by pressing a soft key. After accessing the power device and pressing the Timer soft key, the user can activate the power device for the designated time period by selecting one of the following choices:

  • 1, 5, 10, or 30 minutes
  • 1, 2, 4, or 8 hours

Power Device

Once the Power Control Timer is activated, the device elapsed active time shows on the top line of the DSX 22-Button, 34-Button, or Super Display.

34 power elapsed

Thermostat Run Timer

The Thermostat Run Timer automatically runs when connected heating and cooling units are turned on. If the unit is running, the timer shows how long it has been running. If the unit is not running, the timer shows the total time the unit ran during its last on cycle. The display below shows the following for the example site's Server Room:

  • Temperature is 74 degrees F.
  • Relative Humidity is 42%.
  • The cooling unit is on.
  • The cooling unit has been running for 10 minutes and 53 seconds.

  Software Corrections
  • Caller ID Logging
    • When placing a call from the Caller ID log at a keyset, the user can lift the handset and have the call privately placed in the handset. Pressing SPEAKER toggles between handset and handsfree mode. In prior software versions, pressing SPEAKER could disconnect the call.
  • Directory Dialing
    • If an extension has System Speed Dial Access disabled in System: Class of Service: Features: Features (1401): System Speed Dial Access, the Company directory button is hidden and the System Speed Dial contents cannot be viewed. If an extension has Personal Speed Dial disabled in Stations: Config: Options: Features (2111): Personal Speed Dial, the Personal directory button is hidden and the Personal Speed Dial contents cannot be viewed. In prior software releases, the buttons and contents were not hidden even though the numbers were unavailable.
  • Door Box
    • Door Box call processing has been modified to prevent an extension’s calls from being broadcast over the Door Box. This could potentially occur if an extension user answered a Door Box call handsfree and then pressed Open Door to release the door strike. Ref: F141002001
    • To facilitate answering, an extension can have a Call Coverage key for a SIP Door Box (such as the Algo 8028) even though the extension is not in the Door Box Ring Group. To answer the Door Box call, the user just presses the Call Coverage key. In prior software versions, the Call Coverage key would flash and optionally ring but the user could not answer the call. This is corrected.
  • IntraMail
    • After dialing 2 to initiate Park and Page, the system ignores any additional digits the caller may dial during the Park and Page. In prior software versions, additional dialed digits could cause a prompt to incorrectly play over the paging system.
  • ML440
    • In prior software versions, Call Coverage Delay Ring Feature Keys could ring immediately. This has been corrected. Ref: F150421004
    • In prior software versions, placing a call on Hold could inadvertently place the call on Exclusive Hold (as if the Hold soft key had been pressed twice in succession). This issue is resolved. Ref: F150421003
  • Paging Answer
    • If an extension has a Page key, the user can press the flashing key during a page to talk to the page initiator. In prior software versions, the user could also press INTERCOM + *1 + (the page zone) to answer the page. To prevent inadvertent Paging Answer, this option is no longer available. Paging Answer is only available from a Page key. Ref: F140811001
  • Phone Manager
    • Corrections have been made to the Phone Manager to prevent a system reset when large amounts of System Speed Dial data is submitted. Ref: F150616001
  • Prime Line Preference
    • If an extension has Prime Line Preference set to Intercom, and additionally has access to Speed Dial bins set to Prime Line, the Speed Dial calls will be placed over the extension's dial 9 group (Stations: Config: Options: Groups: Dial 9 Group (2113)). In software version 3.44.06, this feature was inadvertently disabled and would cause a system reset.
    • The Prime Line Preference feature has been rebuilt to correctly handle the case where all lines in the Secondary Prime Line group are busy.
  • Speed Dial, System
    • System Speed Dial bins 1-999 can be stored in System Speed Dial Feature Keys and pressing the key dials the stored number. In prior software versions, pressing a Speed Dial Feature Key with an assigned bin higher than 256 would incorrectly dial a lower numbered bin. Ref: F150218002
  • System Administrator 3.38
    • The action buttons on the On Line: System Directory screen are disabled during the connect state. This includes Edit, Delete, New, Show List, and Folder. In prior releases, only the Delete button was disabled during connect.
    • In prior releases, System: Speed Dial: Import could not import any phone numbers larger than 2147483647. This is corrected in version 3.38.
    • The Stations: Config: Setup: Type: Open Code and Close Code fields are working correctly in version 3.38. In prior releases, data from the Close Code field was inadvertently written into the Open Code field.
    • The programming options for the E911 feature have been added in version 3.38. These options include:
      • System: Class of Service: Features (1401): E911 Alerts
      • System: Options: Setup: E911 (1561): E911 Dialing and E911 Alerting
      • System: Timers: Features: Outgoing (1602): Ring Down Delay
      • System: Timers: Features: Station (1604): E911 Alarm
      • Lines: Groups: Group 99 (E911)
  • VoIP
    • The efficiency and memory usage of the SIP trunk registration process has been improved.
