M3900 Series Meridian Digital Telephones Description, Installation and Administration
Feature overview
M3900 Flash Download provides the capability to download a new firmware
version from the Meridian 1 to an M3900 telephone. Flash Download
provides a way for installed M3900 telephones to be updated to the
appropriate firmware release level for supporting features on the Meridian 1.
Flash Download can be invoked for one M3900 telephone, for a group of
M3900 telephones, or all telephones on the Meridian 1. It can be invoked
locally or remotely for maintenance purposes. Features of the flash download
procedure include the following:
• Set 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 Meridian 1 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 set. It is sometimes referred to as a Peripheral Software DownLoad
(PSDL). Both PSWV and PSDL refers to an actual file that is downloaded to
the M3900 set.
Flash Download requires the use of two software overlays in the Meridian
system. 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.
