Direct Station Selector - AT&T MERLIN LEGEND System Reference Manual

Features

Direct Station Selector

Description
One or two Direct Station Selectors (DSSs) can be connected to an MLX-20L or
MLX-28D telephone assigned as a system operator position. The DSS enhances
the call-handling capabilities of a system operator with a direct-line console
(DLC) or a queued call console (QCC). When connected to an MLX-20L
telephone used as a system programming console, the DSS facilitates system
programming and centralized telephone procedures. When used with the
Extension Status feature or by the calling group or Call Management System
(CMS) supervisor, the DSS allows the user to determine, at a glance, calling
group or CMS group member status or room status.
The DSS provides the following call-handling capabilities or information:
One-touch dialing of inside extensions
One-touch transfer
One-touch hold (DLC only)
On-hook, off-hook, or do-not-disturb status of stations in the system
Extension Status indication (room or group member status)
Calling group queue status
Message-waiting LED status
System operator park zones
The DSS (Figure 2-5) has an array of 50 status/select buttons, called DSS
buttons, with red LEDs. A maximum of two DSSs can be connected together to
provide a field of 100 status/select buttons. Ten additional fixed-feature buttons
with green LEDs are at the bottom of the DSS. The first three (from left to right)
on the top row are Page buttons, which are used to select the range of
extension numbers represented by the status/select buttons. A fourth button
(lower left-most) is the Message Status button, which is used to change to and
from message status operation. The LED next to each DSS button indicates
whether or not a message is waiting from a system operator. The remaining six
buttons on the first DSS and the ten buttons at the bottom of the second DSS are
not operable (reserved for future use).
