Single-Line Sets - Inter-Tel AXXESS Administrator's Manual

AXXESS System Hardware
INTER-TEL AXXESS ADMINISTRATOR'S GUIDE – Issue 5.1, March 2000

SINGLE-LINE SETS

Industry-standard single-line DTMF sets can be installed on the AXXESS System and/or used
as an off-premises extension (OPX). On-premises single-line circuits can be used for installing
AC-ringing 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.

Single-Line DTMF Sets
Single-line DTMF set users gain access to the features by hookflashing (pressing and releasing
the hookswitch quickly) and entering feature codes.
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.
Off-Premises Extensions (OPX)
Off-premises extensions are remote single-line DTMF sets that are connected to the AXXESS
System through telephone company OPX circuits (or customer-provided circuits).
Off-premises station users gain access to the features by hookflashing (pressing and releasing
the hookswitch quickly) and entering feature codes.
Some telephone company off-premises extension (OPX) networks do not recognize certain sin-
gle-line set ring cadences used in the AXXESS System. This incompatibility results in an
inability to provide certain ring signals to off-premises extensions. Because of this, the system
is equipped with a station option (Extended Ring Cadences) which allows the ring cadences be
altered for individual single-line circuits.

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.
