Single-Line Sets
SINGLE-LINE SETS
Industry-standard, single-line DTMF sets can be installed on the system and/or used as an off-
premises extension (OPX). On-premises single-line circuits can be used for installing AC-ring-
ing single-line sets, playback devices, and other single-line devices.
The single-line sets are connected to Single Line Cards (SLCs) or 16-Port Single Line Cards
(SLC-16s). Or, they can be connected to Single Line Adapter (SLA) circuits, which are in turn
connected to available Digital Keyset Card (DKSC or DKSC16) circuits. Off-premises stations
can be connected to SLAs, T1 Cards (T1Cs), or T1/E1 Cards.
•
Each SLC can support up to eight on-premises single-line stations and each SLC-16 can
support up to sixteen stations. The SLC and SLC-16 will support message lamps on sin-
gle-line sets if the optional Lamp Option Card is installed on the SLC or SLC-16.
•
Each SLA can support any combination of up to two single-line sets or DID devices.
•
T1 Card (T1C) and T1/E1 Card circuits can be used for installing off-premises single-
line stations.
Single-Line DTMF Sets
Single-line DTMF set users gain access to the features by performing a hookflash/recall (press-
ing and releasing the hookswitch quickly) and entering feature codes.
Single-Line Caller ID
Version 9.0 or later system supports caller identification (ID) for intercom (IC) calls on a sin-
gle-line device. When a single-line device receives an incoming call, if the system has ade-
quate caller ID resources, the single-line device displays the username and IC extension of the
calling party. This feature allows the single-line device to use the caller ID information to per-
form certain functions.
This feature is supported by single-line endpoints, including endpoints and fax machines con-
nected to a Single Line Card (SLC). The single-line device connected to the SLC must support
caller ID or Calling Line Identity Presentation (CLIP) as defined by current industry-standard
specifications. This feature is not supported on Single Line Adapters (SLAs).
NOTE:
There may be some third-party devices that are documented to support caller ID, but
they actually do not. Because an extension is shorter than a 10-digit number that the device
would normally receive, the device may not be capable of receiving the Caller ID information.
Also, some third-party devices may display the extension in a telephone number format rather
than as an extension number. For example, an extension of 11023 may appear as “110-23,” or
“- 1-1023,” etc.
Single-Line Set Message Lamps
The optional Lamp Option Card (LOC) for the SLC or SLC-16 supports message waiting
lamps. To enable a message waiting lamp on a specific single-line station, the station must
have the Message Lamp station flag enabled. In the default state it is disabled.
SLAs, T1C, and T1/E1 Card circuits cannot support message waiting lamps.
