A failure of a network element is detected automatically. A bootable image of the network element is electronically retrieved upon detection of the failure of the network element. The bootable image is employed to restore the network element.

Restoration of network element through employment of bootable image

This invention is generally directed to minimizing the disruption of subscriber selectable features during the transfer of subscriber lines from a first line unit equipment to a second line unit equipment associated with a telecommunications switch. A second data assignment table which is based on a first data assignment table is utilized in conjunction with a digital telecommunications switch to facilitate an improved service transition when subscriber lines are to be transferred from a first type of line unit equipment to a second type of line unit equipment. The data assignment tables contain for each telephone number an identification of a line unit address utilized to support that telephone number and corresponding parameters which identify which customer selectable features are active. The second data table duplicates the parameter defining features in existence in the first table as of the time of creation of the second table, but substitutes different line unit addresses corresponding to the new line unit equipment for each telephone number to be supported. Upon a physical transition to the new equipment, the second data table is activated so that upon a resumption of service customers will have access to previously defined features as defined in the second table.

This invention relates to arrangements for simplifying the transfer of a source of telecommunications signals, such as a telecommunications customer line or telecommunications trunk, from a first port of a switching system to a second port of that same switching system. Such a transfer requires a transfer of a connection in the outside plant, usually in a manhole, and establishment of a connection from the outside plant to the second port, usually in a distributing frame of the switching system. Translation data is stored for the second port to indicate availability of the second port for assignment to a customer, and, in one embodiment of the invention, to identify the customer to be connected to that second port. In accordance with that embodiment of the invention, the customer line to the first port is tested in the manhole to verify the identity of that customer; the line to the second port is tested to see if the translation data for that second port comprises the same customer identification. If so, a request to assign the translation data for that customer to the second port is then transmitted from the manhole. In response to an acknowledgment that the translation data has been so assigned, the customer's line is transferred to the second port. Advantageously, the translation data can be stored and a connection to the second port can be established ahead of time in the switching system, and the transfer of the line can be carried out by one individual in the manhole without requiring the cooperation of other craft in the switching system.
