82 Strata DK General Description 6/00
Memory Protection
If the power fails, the Strata DK has an internal battery backup that protects data and the
customers programmed configuration. This information will be maintained within a powerless
system for at least six years.
Message Waiting
Any station and most voice mail devices can leave a message waiting indication (light) on a
designated message waiting light of a digital, electronic, or standard telephone station.
Message waiting lights can be activated when a voice mail message has been left, or they can be
turned on by a calling station. The station user can retrieve messages by pressing the button next to
the message waiting light.
DK14 and DK40i QSTU2 and KSTU2 PCBs do not support standard telephone MW lamps.
DK40i, DK424i an RSTU2 PCB must be connected to a standard telephone with a MW
lamp to enable this feature. These DK systems provide Messages Waiting to standard
telephones with a message waiting lamp. The user can enter an access code to retrieve the
messages. A standard station can store up to four indications.
Multiple Directory Numbers
A [DN], sometimes called an extension number, is the number someone must call to reach a
destination within the system. To maximize call coverage flexibility, station [DNs] can appear on
multiple telephones. Also, individual telephones can have multiple [DNs] (see Figure 17).
The system provides three types of [DNs]: Primary, Secondary and Phantom. All [DNs] can be
used to originate and answer calls. If you press a [DN] while on a call, it releases the existing call
and provides dial tone to make another call.
DK14 supports a maximum of 10 [PDNs] and 10 [PhDNs]
DK40i supports a maximum of 28 [PDNs] and 28 [PhDNs]
DK424i each support a maximum of 336 [PDNs] and 336 [PhDNs] (See Table 38 for
maximum capacities for various common control units)
Primary Directory Number [PDN]
Each station in the Strata DK has a unique [PDN]. This [PDN] can appear on multiple buttons (up
to four) of the primary station.
Secondary Directory Number [SDN]
When the [PDN] of a station appears on another station, it becomes an [SDN]. Any [PDN] can
appear as an [SDN] on all other Toshiba telephones in the system. A [PDN]/[SDN] can ring on up
to 120 telephones in the system. Each telephone can be assigned up to four of the same [SDN]. The
maximum number of [PDNs] plus [SDNs] on each telephone is 16.
