Single-Line Set Message Lamps
12.111The optional Lamp Option Card (LOC) for the SLC or SLC-16 supports message wait-
ing lamps. To enable a message waiting lamp on a specific single-line station, the station must
have the Message Lamp station flag enabled (see page 6-212 in PROGRAMMING). In the
default state, it is disabled.
12.112SLAs, T1C, and T1/E1 card circuits cannot support message waiting lamps.
Single-Line Ring Zones and Extended Ring Cadences
12.113In some installations, where more than one single-line device is connected in series to
an SLC or SLC-16 circuit, zoned ringing may be necessary. The system can support devices
with up to 3 Ringer Equivalences (REs) per circuit. However, the system can only ring 8 REs
per board. If the installation exceeds eight REs on any SLC or SLC-16, the system-wide SLC
Ring Zones flag must be enabled (see page 6-261 in PROGRAMMING). Also, all circuits on
the SLC or SLC-16 should have the Extended Ring Cadences station flag enabled to allow the
longer cadence to be used instead of the short internal cadence (see page 6-211 in PROGRAM-
MING).
12.114With ring zones enabled, devices 1-3 on the card will ring first, 4-6 ring next, and so on
until all devices have rung.
12.115The table below explains the difference between standard and extended ring cadences
for the various types of single-line devices used on the Inter-Tel system in the United States
and Europe.:

Single-Line Device Cadence Type Description
SLA, SLC, SLC-16,
or T1 OPX
Standard IC Ring This is a repeating 2-second cadence that
rings twice. Each ring lasts 200 ms and is sep-
arated from the next ring by 400 ms of silence.
The remaining 1.2 seconds is silent.
Extended IC Ring This is a repeating 6-second cadence that
rings twice. Each ring lasts 800 ms and is sep-
arated from the next ring by 400 ms of silence.
The remaining 4 seconds is silent
Standard CO Ring This is a repeating 6-second cadence that
rings once for 2 seconds followed by 4 sec-
onds of silence.
Extended CO Ring Same as Standard CO Ring cadence.
Executive, Profes-
sional, Standard,
Associate, Model
8520, or Model 8560
Phone MDPM
Standard IC Ring This cadence has two 250 ms rings every 2
seconds.
Extended IC Ring This is a repeating 3-second cadence that
rings once for 1 second followed by 2 seconds
of silence.
Standard CO Ring This is a repeating 6-second cadence that
rings once for 2 seconds followed by 4 sec-
onds of silence.
Extended CO Ring This is a repeating 6-second cadence that
rings once for 4 seconds followed by 2 sec-
onds of silence.
