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 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.

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. 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.

Off-Premises Extensions (OPX)

Off-premises extensions are remote single-line DTMF sets that are connected to the Inter-Tel 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 system. This incompatibility results in an inability to pro- vide 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.

AGENTSET

The AgentSet is used in place of an Inter-Tel phone with an attached PCDPM. It is connected to a Digital Keyset Card (DKSC or DKSC-16) port just as a phone would be. It has a jack for plugging in an Inter-Tel handset or headset. It also has a serial connector (DB9) for attaching it to a PC. The AgentSet does not require a transformer or external power source.

To operate properly, the AgentSet must be programmed for headset mode. This can be done in one of the following ways:

•

Enable Headset Mode via Station Programming in the system database

•

At the AgentSet, unplug the headset or handset (to take the AgentSet off hook) and enter the Headset On/Off feature code (317) to enable headset mode. Then plug in the headset or handset.

NOTE: There is nothing to prevent the user from disabling headset mode using the Headset On/Off feature code at the station.

Because the AgentSet does not have feature buttons, a dialing pad, or a speaker, it must be con- nected to a PC that is equipped with an OAI product that emulates an Inter-Tel phone. The OAI product is used for dialing and feature access.

The AgentSet also requires an Inter-Tel headset or handset. Only Inter-Tel equipment should be used. Other manufacturer’s equipment may not be compatible with the AgentSet.

If the user wishes to receive audible signals at the headset, there is a station flag that will send a single tone to the headset when a call is ringing. (Refer to page 81.)
