Panasonic Digital Phones

E-MetroTel is pleased to announce that our efforts to integrate the support for select Panasonic Digital Phones connected via our DSM16p card interface into our UCX software have progressed to readiness for beginning beta trials. This integration is part of our overall strategy to enable graceful, cost effective migration of customers with investments in legacy equipment to a modern, fully featured unified communications platform complete with full featured voice, video and messaging support.

Supported Devices

E-MetroTel has focussed on integration of two of the more popular and widely deployed Panasonic digital phone models (other models may be supported in the future):

  • KX-DT521 Digital Telephone with 1-Line Display
  • KX-DT543 Digital Telephone with 3-Line Display

Both of these models will be supported on any of our existing DSM16p cards after the application of a software update to both the DSM16p card and the UCX software.  The updated DSM16p software adds a new Digital Set Mode to the Gateway / Device Configuration page to enable the card to support a full complement of a maximum of 16 Panasonic digital phones. Note that while a single DSM16p can only support one Digital Set Mode, multiple digital set types can be supported across multiple DSM16p cards connected to a single UCX based system. The updated UCX software, which can be running on a premise based appliances, virtualized, or cloud based environments, allows the selection of either the KT521 or the KT543 phones in the Device Type setting in the Nortel Properties page.

Limitations

Current Limitations

The following list represents limitations that are based on the current state of development at the time of the creation of this document and is subject to change after further testing and development effort:

  • The volume control function is not fully working on the phone
  • Line key LEDs may turn off during the call
  • Shared Call Appearance has not been fully tested
  • Call Log has not been fully tested

Planned Limitations

The following is a list of planned limitations that will exist even after the formal product release:

  • DECT base stations are not supported via the Panasonic digital interface
  • Digital XDP mode is not supported (each Panasonic telephone must be connected directly to the DSM16p on a dedicated pair)
  • Set Relocation is not supported (Note: an extension is tied to the DSM16p port, not the telephone. However, UCX Hotdesking will allow that extension to be used on a different telephone connected to a different port.)
  • The maximum loop length for Panasonic sets on the current DSM16p implementation is 200 feet (60 meters). A new DSM16p design is planned that will enable a maximum loop length of over 1000 feet (304 meters). However, it is important to note that mulitple DSM16p cards deployed in separate Galaxy Express chassis dispersed throughout a large building (connecting back to the UCX software though standard ethernet network) can be used to extend the coverage and effectively shorten the required loop lengths for the phones. See the image below for an example:

Note that the wiring pinouts on the line cord connectors on Panasonic digital phones is different than the pinout used on similar sized connectors on Nortel and Avaya phones.  Please ensure you have the correct pins connected. Also note that the standard RJ-21 connector pinout for the DSM16p connection also applies to the DSM16p when in Panasonic Digital Set Mode.
