Claim 1
Independent Claim
163 words
A method for limiting the number of build-up packets during the process of building-up a routing address for the subsequent transmission of address-coded packets, the addresses of these packets being this said routing address, from a first to a second subscriber of a digital telecommunication network, this network comprising, a plurality of switching nodes, a plurality of subscribers including said first and second subscriber, a plurality of bearer channels connecting each switching node with at least one other switching node and with no, one or more of said subscribers, a plurality of routing words individually assigned to said bearer channels, a plurality of call numbers individually assigned to said subscribers, in which said process of building-up a routing address, the first subscriber dispatches a build-up packet containing the call number of the called second subscriber, said build-up packet received by the switching node connected to the first subscriber is retransmitted by this switching node through all bearer channels connected to this switching node,
Claim 2
Independent Claim
163 words
A method for limiting the number of build-up packets during the process of building-up a routing address for the subsequent transmission of address-coded packets, the addresses of these packets being this said routing address, from a first to a second subscriber of a digital telecommunication network, this network comprising, a plurality of switching nodes, a plurality of subscribers including said first and second subscriber, a plurality of bearer channels connecting each switching node with at least one other switching node and with no, one or more of said subscribers, a plurality of routing words individually assigned to said bearer channels, a plurality of call numbers individually assigned to said subscribers, in which said process of building-up a routing address, the first subscriber dispatches a build-up packet containing the call number of the called second subscriber, said build-up packet received by the switching node connected to the first subscriber is retransmitted by this switching node through all bearer channels connected to this switching node,
Claim 3
Dependent Claim
128 words
such retransmission is continued at each switching node upon reception of a build-up packet, the method of limiting the number of said build-up packets comprising at each switching node, storing of the said call number of the second subscriber upon reception of a first build-up packet during a preetermined time interval, which starts with the reception of said first build-up packet, comparing during said time interval the call numbers contained in the subsequently received build-up packets with the call number stored, counting of all said subsequently received build-up packets with a call number corresponding wth the call number stored, comparing the respective count with a predetermined limiting value, and eliminating each of said subsequently received build-up packet, if said respective count is higher than said predetermined limiting value.
Claim 4
Dependent Claim
128 words
such retransmission is continued at each switching node upon reception of a build-up packet, the method of limiting the number of said build-up packets comprising at each switching node, storing of the said call number of the second subscriber upon reception of a first build-up packet during a preetermined time interval, which starts with the reception of said first build-up packet, comparing during said time interval the call numbers contained in the subsequently received build-up packets with the call number stored, counting of all said subsequently received build-up packets with a call number corresponding wth the call number stored, comparing the respective count with a predetermined limiting value, and eliminating each of said subsequently received build-up packet, if said respective count is higher than said predetermined limiting value.
Claim 5
Dependent Claim
158 words
A swiching node of a digital telecommunication network for the transmission of addressed-coded packets comprising, a sorting switch (80) for separating information packets and build-up packets, a shift register (82) for storing the incoming build-up packets, a store (84) for storing the call-number contained in the first incoming build-up packet for a predetermined time interval, starting by storing the said call-number, a comparator circuit (83) connected to said register (82) and said store (84), a counter (95) controlled by said comparator circuit (83) for counting the subsequent incoming build-up packets whose call-number corresponds to the call-number stored in said store (84), a logic circuit (96, 97) controlled by said counter (95) for causing retransmission of the build-up packet, stored in said register (82), if the position of the counter is lower than or equal to a predetermined limiting value, and a timing circuit (87) for resetting said store and said counter on the end of said time interval.
Claim 6
Dependent Claim
158 words
A swiching node of a digital telecommunication network for the transmission of addressed-coded packets comprising, a sorting switch (80) for separating information packets and build-up packets, a shift register (82) for storing the incoming build-up packets, a store (84) for storing the call-number contained in the first incoming build-up packet for a predetermined time interval, starting by storing the said call-number, a comparator circuit (83) connected to said register (82) and said store (84), a counter (95) controlled by said comparator circuit (83) for counting the subsequent incoming build-up packets whose call-number corresponds to the call-number stored in said store (84), a logic circuit (96, 97) controlled by said counter (95) for causing retransmission of the build-up packet, stored in said register (82), if the position of the counter is lower than or equal to a predetermined limiting value, and a timing circuit (87) for resetting said store and said counter on the end of said time interval.
