SX-200 General Information Guide

A CENTREX extension can be put on softhold to dial another extension, by sending out a Flash Over Trunk followed by the digits of the extension. If the caller hears busy or ringing, the CENTREX extension can be put on softhold again, and the Double Flash Over Trunk feature access code can be dialed. This sends out two flashes on the trunk, with one second between the flashes. When the CENTREX service receives the double flash, it clears the ringing/busy tone. The caller returns to a talking state with the trunk that was on softhold.

The trunk must be in a trunk group in order to flash over the trunk and the feature can be used by telephones only. The feature only functions if one trunk is on consultation hold and cannot be used with a conference on consultation hold.

CENTREX Compatibility (Single Flash Over Trunk)

This feature provides the ability to send a switchhook flash out over a trunk. Flashing over a trunk allows for the use of CENTREX features by telephones within the system. Callers must follow instructions specified by the local central office concerning which access codes to dial, and when to wait for dial tone. After sending the flash over the trunk, the system will wait for dial tone from the central office, or for the Limited Wait For Dial Tone timer.

Speed Call: The Access Code for Flash Over Trunk, followed by digits which make sense to the local central office may be programmed into a Speedcall key, or a System Abbreviated Dial Number. The trunk must be in a trunk group in order to flash over the trunk. Any central office access code with an asterisk (*) in it must be entered as **.

CLASS (Custom Local Area Signaling Services) for Analog Telephones

CLASS (station side) for Analog Telephones allows the SX-200 EL or the SX-200 ML system to pass Calling Line ID digits and CLASS name information through to analog stations, such as display sets, that support Caller ID functionality.This feature supports a calling name and number display (if available) to a ringing set and to a set in talk state (a visual call waiting or campon). The CLASS message is also able to activate and de-activate the message lamp. To maintain privacy, the CLID information is cleared on checkout.

CLASS (Custom Local Area Signaling Services) for Digital Sets

Available on the SX-200 SPINE nodes and on the LS/CLASS Trunk cards in the SX-200 rackmount cabinets. The system receives Calling Line ID digits or CLASS name on incoming Loop Start (LS) CLASS trunks. The calling directory number or name is presented to SUPERSET display telephones, to SUPERSET 7000 and SUPERCONSOLE 1000 consoles, to SMDR printers, and to the MITEL Application Interface (MAI) platform package.

Class of Restriction (COR)

Fifty Class of Restriction (COR) groups are available in the system to give 50 different levels of outgoing call capabilities. Each extension, SUPERSET telephone, dataset, console or dial-in trunk is assigned a COR that defines the outgoing call privileges for that device. All devices with the same COR have the same outgoing call privileges. The Class of Restriction allows the system to restrict which trunks cannot be accessed by a user.
