Page 228 of 504 M3900 Flash Download
553-3001-367 Standard 3.00 August 2005
Download provides a way for installed M3900 telephones to be updated to the
appropriate firmware release level for supporting features on the system.
Firmware on all M3900 Series Digital Telephones can be upgraded using
Flash Download, with the exception of the M3901. Flash Download can be
invoked for one M3900 telephone, for a group of M3900 telephones, or all
telephones on the system. It can be invoked locally or remotely for
maintenance purposes. Features of the flash download procedure include the
following:
• Telephone type can be specified (M3902, M3903, M3904, M3905, All)
• Day(s) of week can be specified
• Up to four intervals per day can be specified (start time, length)
• TN Range can be specified (start TN, end TN)
• DN Range can be specified (start DN, end DN)
• Force Download can be specified (yes, no)
Flash download is incorporated in the existing Peripheral SoftWare Version
(PSWV) background tasks of the Work Schedule. Therefore, regular call
processing is impacted as little as possible. In the context of this document,
PSWV represents the firmware file that is downloaded to an M3900
telephone. It is sometimes referred to as a Peripheral Software DownLoad
(PSDL). PSDL is a file that holds PSWV for hardware (for example,
terminals or trunk cards) that supports a firmware upgrade.
Flash Download requires the use of two software overlays. Use LD 97 to
configure the parameters for the Flash Download capability. Use LD 32 to run
the feature. Before the Flash Download feature is used, configure the feature
in LD 97.
