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.
Single-Line Ring Zones and Extended Ring Cadences
In 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. 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 inter-
nal cadence.
With ring zones enabled, devices 1-3 on the card will ring first, 4-6 ring next, and so on until
all devices have rung.
The table below explains the difference between standard and extended ring cadences for the
various types of single-line devices used on the Inter-Tel phone system in the United States.
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 separated
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 separated
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 seconds of
silence.
Extended CO Ring Same as Standard CO Ring cadence.
Model 8560, Model 8520,

Standard and
Associate 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 seconds of
silence.
Extended CO Ring This is a repeating 6-second cadence that rings
once for 4 seconds followed by 2 seconds of
silence.
