DE3024787A1 - PABX night service call queuing - directing incoming calls directed to designated extensions in priority order - Google Patents

Abstract

Out of service, i.e. night service, arrangements are provided for a PABX using a switch block and data highway connections to the common control and peripheral controls. No calls are lost due to nominated night service extensions in a priority order as they come in. The extensions are nominated in a determined order so that the calls can be switched through on a PBXing basis through the exchange.

Description

Procedure for centrally controlled telecommunications switching

, in particular private branch exchanges with attendant sets.

The invention relates to a method for centrally controlled telecommunications switching systems, in particular Fernspre chnebenstelleanlagen with a speech path coupling network and with for exchanging switching technology, for establishing a connection via the Speech path network serving data, addresses and control commands between for different Tasks provided for separate partial controls with several operator stations with different modes of operation, with the allocation of individual calls to the Operator stations are carried out through a call folder and call distributor.

It is already a method for a centrally controlled telephone exchange proposed (P 29 12 764), in which operator places are provided, with each Operator console a centrally arranged one containing the status and the operating mode State memory is assigned and where the operating mode after commissioning the Switchboard to any other operating mode provided in the system - e.g. also night operation - can be changed.

The object of the invention is now to consist in one of the above PBX to create a way to switch off all Switchboards e.g. incoming calls to one or more during night operation normal subscribers make the system divert without losing a call goes.

This is achieved according to the method according to the invention in that the call folder and call distributor can be controlled from an organizational control unit is that when all switchboards are taken out of service, all incoming calls to one or one of several normally designed subscriber stations, at the same time the subscriber station or stations selected for this purpose have a waiting chain is assigned for further pending calls and being selected in the case of several Participant positions in a definable order the next free participant position or if all selected subscriber stations are occupied, the next one with the fewest The subscriber who is already waiting for a call is occupied by another call or is also occupied.

This has the advantage that even with a larger one centrally controlled telephone exchange, for example, all switchboards during night operation can be switched off and still after switching off the attendant consoles incoming calls can still be accepted.

In the method according to the invention, one of the aforementioned State of the art centrally controlled private branch exchange went out. It is easily conceivable that one of the mentioned switching stations is switched to "night mode" so that ane incoming calls and all switching requests be directed to him. It is also conceivable that it is in such a system At times it is not worthwhile to operate such a switchboard during the night to be maintained, since no outgoing switching requests and only a few incoming ones Calls are to be expected, the latter from - permanent, not to one Operator station belonging, only equipped with normal telephone stations Personnel can be done.

If you assign these telephone stations in principle or on a case-by-case basis The case is determined by adding their address and a corresponding identifier in the address memory to be scanned during a call enters, then a further code 11 to be entered is sufficient for all switching stations out of order "to answer an incoming call to one of the to forward operable telephone stations. As also for the operator stations a priority can be provided, can be used simultaneously with the indicator "all Switching places out of order "the priority list of the provided telephone stations be assigned, with only a conversion of the attendant console addresses must be made in the respective telephone station address.

Furthermore, with the indicator "all switching places except Operation "assigned a waiting chain to the individual telephone stations, as in the operator stations in the company. This can be used at a telephone station Several other calls are pending while a call is being answered. This is then the case when the call folder and call distributor for another incoming Call no longer finds a free telephone station intended for night operation. He then occupies the waiting chain of the next subscriber station that can be occupied by him with the incoming call, so that this station now has to handle two calls. For further incoming calls, a free or a subscriber station with fewer than two calls to be processed selected. Only when two calls to be processed have been allocated to all subscriber stations will any next subscriber station or one determined in the priority list occupied a third call on the waiting list.

From the above it appears that it is according to the invention Procedure in a simple way is possible in a centrally controlled Telephone exchange system with attendant consoles when all attendant consoles are switched off E.g. one or more calls that are intended for this purpose are still arriving during night operation To forward subscriber stations, with the intended subscriber station or stations a waiting chain and, if necessary, a priority can be assigned at the same time can.
