System Features

Line Groups

For easy access, various types of outside lines can be assigned to groups (normally for pooled line
and LCR applications). For example, all local lines can be assigned to one group and WATS lines
in another group. Station users access line groups by dialing an access code or by pressing a
feature button.
DK14 provides up to 4 line groups
DK40i provides up to 8 line groups
DK424 provides up to 16 line groups

Line Queuing

A station user can use the Automatic Callback feature to enter the queue for a busy outgoing line.
When the line becomes available, the system calls the station back. Queuing applies to single lines,
line groups, and when calling via LCR.

Live System Programming

Programming the Strata DK from an on-site or off-site location does not interrupt the operation of
the system in most cases. It is interrupted for hardware upgrades.

Memory Protection

If the power fails, the Strata DK has an internal battery backup that protects data and the
customer's 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.
DK424 and DK40i – an RSTU2 PCB must be connected to a standard telephone with a MW
lamp to enable this feature. The DK40i and DK424 provide Message 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
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]
DK424 supports a maximum of 336 [PDNs] and 336 [PhDNs] (see
capacities for various common control units)
