Abstract
A boot program which can independently set the signaling links with the exchange is stored in the memory of a line concentration group. Under this boot program, a signaling controller (SGC) is used to set up a signaling link from the line concentrator to the exchange. Through the signaling link, a call processing program is transferred from the exchange side to the line concentrator side, and the transferred call processing program is used to start up the line processor in the line concentration group.
Claims18
A method for starting a switching system including an exchange, having at least a program holding unit in which various programs are held, a call processor, and a switch module controlled by the call processor, and a line concentration group provided between the exchange and a plurality of subscriber telephone sets accommodated in the exchange, the line concentration group including a line concentrator and a line processor which controls the line concentrator based on a call processing program, said method comprising the steps of:
- (I) storing in the line concentration group a boot program which can independently set signaling links with the exchange,
- (II) setting up, under the boot program, a signaling link from the line concentration group to the exchange,
- (III) transferring a call processing program through the signaling link set up in step (II) from the exchange to the line concentration group, and
- (IV) starting up the line processor in the line connection group under control of the call processing program transferred in step (III).
An apparatus for starting a switching system, comprising:
- an exchange, including
- a program holding unit storing programs,
- a call processor operatively connected to said program holding unit, and
- a switch module operatively connected to said call processor and controlled by said call processor, and
- a line concentration group provided between a plurality of subscriber telephone sets and said exchange, said line concentration group including
- a line concentrator operatively connected to the subscriber telephone sets;
- a line processor, operatively connected to said line concentrator, controlling the line concentrator based on a call processing program,
- memory means for holding a boot program which can independently set signaling links with said exchange;
- signaling link setup means for setting up a signaling link based on the boot program in said memory means;
- and
- starting means for receiving the call processing program from said program holding unit through the signaling link set up by said signaling link setup means and for starting up said line processor.
An apparatus for starting switching in a system having an exchange connected to a line concentration group, said apparatus comprising:
- program holding means at the exchange for holding a call processing program;
- switching means at the exchange for switching calls;
- call processing means at the exchange for processing calls by controlling the switching;
- line concentrating means at the line concentration group for concentrating lines;
- line processing means at the line concentration group for controlling the concentrating based on a call processing program;
- memory means at the line concentration group for storing a boot program;
- signaling link setup means at the line concentration group for setting up a signaling link with the exchange based on the boot program;
- and
- starting means at the line concentration group for receiving the held call processing program over the set up signaling link with the exchange based on the boot program.
A method of starting a line concentration group connected by signaling links to an exchange, said method including the steps of:
- (a) storing in the line concentration group a boot program which can independently set signaling links with the exchange;
- (b) setting up by control of the boot program a signaling link between the line concentration group and the exchange;
- (c) transferring through the signaling link from the exchange to the line concentration group a call processing program;
- (d) storing in the line concentration group the call processing program;
- (e) starting the line concentration group after storing the call processing program in the line concentration group;
- and
- (f) performing switching in the line concentration group to enable connection of calls between the line concentration group and the exchange.
