System for working at a remote office PBX
First Claim
1. An arrangement comprising:
- a switching network;
a digital network;
a first PBX includingtrunks connected to said switching network,lines adapted to operate with telephonic instruments,a first processor for controlling operation of the first PBX,a first memory associated with said first processor, anda digital port coupled to said first processor, through which information contained in said first PBX can be accessed, and through which control signals can be applied to store in said first memory and thereby control manner of operation of said first PBX;
a first security processor for coupling the digital port of said first PBX to said digital network, for insuring that only bona fide messages pass through to said digital port from said digital network;
a second PBX includingtrunks connected to said switching network,lines adapted to operate with telephonic instruments,a second processor for controlling operation of said second PBX,a second memory associated with said second processor, anda digital port coupled to said second processor through which information contained in said second PBX can be accessed, and through which control signals can be applied to store in said second memory and thereby control manner of operation of said second PBX; and
a second security processor for coupling the digital port of said second PBX to said digital network, for insuring that only bona fide messages pass through to said digital port from said digital network;
wherein said first memory contains a calling plan module that specifies telecommunication capabilities of line A of said first PBX, and a directive that specifies a line B in said second PBX that is to be used instead of line A, and said second memory contains a directive that line B is to be treated as if it is line A, and a module associated with line B that contains a facsimile of said calling plan module contained in said first memory.

Abstract
An arrangement that includes at least two PBXs interconnected by a network employs CTI ports to control operation of the PBXs. Through such control, a user can set up a telephonic presence in a visited PBX such that, to the user and to all others who interact with the user, it appears that the user is at the user'"'"'s office, rather than at an office that is served by the visited PBX. This is effected by forwarding calls that are destined to the user at the user'"'"'s office to the visited PBX, and by translating all dialing commands of the user at the visited PBX, and acting upon the translated commands, so as to provide the user with the features available to the user at the user'"'"'s office while presenting an appearance to called parties that the user is at the user'"'"'s office.

8. A method for providing virtual telephonic presence at a first telephonic instrument served by a first PBX while physically present at a second telephonic instrument served by a second PBX, comprising the steps of:
-
said first PBX receiving a request, on behalf of line B of said second PBX, to provide a calling plan of line A of said first PBX which describes telecommunication capabilities of a telephonic instrument connected to said line A; installing in said first PBX information about said line B of said second PBX, including a directive that said line B is to be used in all communications pertaining to said line A; said fist PBX delivering said calling plan of said line A to said second PBX; installing in a memory accessible by said second PBX, in association with said line B, said calling plan pf said line A, a directive to provide service to said line B in accord with said calling plan of said line A, and information that allows outgoing calls from said line B to provide caller ID information of said line A; and said first PBX and said second PBX cooperating to provide to said line B outgoing and incoming telecommunication service in accord with said calling plan of line A and in a manner that is transparent to users. - View Dependent Claims (9, 10, 11, 12)

13. A method for providing virtual telephonic presence at a line A of a first PBX while physically present at a telephonic instrument connected to line B of a second PBX, comprising the steps of:
-
receiving a connection request at said telephonic instrument; determining that a directive exists with respect to said telephonic instrument that a foreign calling plan is to be emulated, which foreign calling plan is a calling plan for line A, previously obtained from said first PBX and installed in said second PBX to be associated with said line B; translating said connection request in accordance with information regarding said calling plan to create translated connection request; and undertaking to establish a connection pursuant to said translated connection request. - View Dependent Claims (14, 15)
