Abstract

The method for assigning an identification number is constructed in that in a transmission system with transmission system managing equipment being connected to at least one of a plurality of pieces of connected transmission equipment, each of all or some of the transmission equipment acquires information peculiar to adjacent devices connected thereto and holds the information as peripheral connected-state data of each piece of transmission equipment. The transmission system managing equipment collects information from all of the transmission equipment which hold the peripheral connected-state data of each piece of transmission equipment, and on the basis of the information, determines and transmits an identification number for each piece of transmission equipment. Each of the plurality of pieces of transmission equipment carries out internal setting of the identification number thereof transmitted from the transmission system managing equipment. By this duplication of the same identification number among different pieces of transmission equipment, setting error or the like in setting the number can be avoided.

Claims

1. A method of assigning a transmission-equipment identification number such that an identification number is assigned to each of a plurality of connected transmission apparatuses in a transmission system in which a transmission system managing apparatus is connected to at least one of the plurality of connected transmission apparatuses, said method comprising:

acquiring, with at least one of the plurality of transmission apparatuses, information peculiar to adjacent transmission apparatuses connected to the at least one of the plurality of transmission apparatuses, respectively;

holding the information as peripheral connected-state data of the at least one of the plurality of transmission apparatuses in the at least one of the plurality of transmission apparatuses, respectively;

collecting, with the transmission system managing apparatus, the information from the at least one of the plurality of transmission apparatuses;

determining and transmitting, with the transmission system managing apparatus, based on the information, an identification number for the at least one of the plurality of transmission apparatuses;

performing, in the at least one of the plurality of transmission apparatuses, internal setting of the identification number of the at least one of the plurality of transmission apparatuses, respectively, transmitted by the transmission system managing apparatus.

2. A method as claimed in claim 1, wherein:

said acquiring is performed with each of the plurality of transmission apparatuses, respectively, so as to acquire information peculiar to adjacent transmission apparatuses connected to each of the plurality of transmission apparatuses, respectively;

said collecting is performed such that information from each of the plurality of transmission apparatuses is collected;

said determining and transmitting is performed so as to determine and transmit an identification number for each of the plurality of transmission apparatuses; and

said performing of internal setting is performed in each of the plurality of transmission apparatuses so as to internally set the identification number of each of the plurality of transmission apparatuses, respectively.

3. A method as claimed in claim 1, comprising:

acquiring, with each of the transmission apparatuses, the peripheral connected-state data of each of the plurality of transmission apparatuses, respectively, when each of the plurality of transmission apparatuses receives a request for alteration of adjacent-station information from the transmission system managing apparatus.

4. A method as claimed in claim 1, comprising:

acquiring, with a newly-installed transmission apparatus, information peculiar to adjacent transmission apparatuses connected to the newly-installed transmission apparatus; and

holding the information peculiar to the adjacent transmission apparatuses connected to the newly-installed transmission apparatus as peripheral connected-state data of the newly-installed transmission apparatus in the newly-installed transmission apparatus.

5. A method as claimed in claim 1, for further use with an additional transmission system managing apparatus, said method comprising:

directly transmitting a request for setting identification numbers from the transmission system managing apparatus to the additional transmission system managing apparatus after the transmission system managing apparatus has received the identification number set in the at least one of the plurality of transmission apparatuses so as to allow a setting of identification numbers in the additional transmission system managing apparatus.

6. A transmission system comprising:

a plurality of connected transmission apparatuses; and

a transmission system managing apparatus, connected to at least one of said transmission apparatuses, operable to output a request for adjacent-station information to said at least one of said transmission apparatuses and to output, to said at least one of said transmission apparatuses, a request for identification-setting including an identification number assigned to said at least one of said transmission apparatuses, respectively;

wherein each respective transmission apparatus of said plurality of transmission apparatuses includes

a peripheral connected-state acquiring device operable to acquire information peculiar to adjacent transmission apparatuses connected to said respective transmission apparatus, and to hold the information as peripheral connected-state data of said respective transmission apparatus,

a peripheral connected-state transmitting device operable to transmit the peripheral connected-state data to said transmission system managing apparatus in accordance with the request for adjacent-station information from said transmission system managing apparatus, and

an identification number setting device operable to internally set an identification number of said respective transmission apparatus in accordance with the request for setting identification number from said transmission system managing apparatus; and

wherein said transmission system managing apparatus includes

an updating request device operable to transmit a request for updating adjacent-station information to said at least one of said transmission apparatuses, and

an information collecting device, operable to collect the peripheral connected-state data from each of said transmission apparatuses holding peripheral connected-state data.
