When ic is an odd number, subtract 1 and when it is even, add 1 M
An SU change unit, an MSU analysis unit that determines and starts a reception processing unit that performs processing corresponding to the information according to various information in the received MSU, and switches the electronic exchange between a test state and an operational state. A configurable changeover switch, when the changeover switch is in operation state, the received MSU is sent as is to the MSU analysis department, and when it is in test state, the received MSU is sent directly to the MSU analysis department.
It is equipped with a switching monitoring unit that sends U to the MSU analysis unit via the MSU changing unit, and the line numbers CIC are adjacent and odd numbers.
It is configured by performing a common line signaling system connection call test on its own by performing call control according to the processing result in the reception processing section with two lines to the same opposing station of even numbers being looped back.
本発明の共通線信号方式を具備する電子交換機において
、信号線および通話線の工事試験を行うための共通線信
号方式における試験方式に関するものである。The present invention relates to a test method in the common line signaling system for carrying out construction tests on signal lines and communication lines in an electronic exchange equipped with the common line signaling system according to the present invention.
２局の交換機間において制御用情報を送受する中継線信
号方式としては、制御用情報を通話線を経て伝送する個
別線信号方式と、専用回線（共通線）を設けてその上を
ディジタル化した制御用情報を伝送する共通線信号方式
とがある。The trunk line signaling system for transmitting and receiving control information between two exchanges includes an individual line signaling system that transmits control information via a telephone line, and a dedicated line (common line) that is digitized. There is a common line signaling system that transmits control information.
共通線信号方式は、信号線と通話線とを一体化した個別
線信号方式と異なり、信号線を通話線と独立して具備す
るため、局間において種々の情報を随時かつ高速に転送
できる利点があり、従って局間における接続時間の短縮
１局内サービスの局間への拡張、ｌ５ＤＮへの対応等を
期待することができ、ＰＢＸ市場における導入要求が強
まっている。Unlike the individual line signaling system, which integrates the signal line and the communication line, the common line signaling system has the signal line independent of the communication line, so it has the advantage of being able to transfer various types of information between stations at any time and at high speed. Therefore, it can be expected to shorten the connection time between stations, expand intra-station services to inter-station services, support I5DN, etc., and the demand for introduction in the PBX market is increasing.
このような共通線信号方式を導入するに当っては、対向
局との接続試験についての配慮が必要であり、特に対向
局がまだ対向試験を行うことができない状況にある場合
に、自局単独で試験可能にすることが要望される。When introducing such a common line signaling system, consideration must be given to the connection test with the opposite station, especially when the opposite station is not yet able to perform the opposite test. It is requested that the test be made possible.
個別線信号方式においては、対向局が対向試験を行うこ
とができない状態にある場合、この対向局向けの中継線
に対してジャンパ架（ＭＤＦ）上でそれぞれ他の中継線
へ折り返すジャンパを設定することによって、自局だけ
で対向局への接続試験を行うことができる。In the individual line signaling system, if the opposing station is unable to perform an opposing test, a jumper is set on the jumper frame (MDF) for each relay line destined for the opposing station to loop back to other relay lines. By doing so, it is possible to perform a connection test to the opposite station using only the local station.
しかしながら共通線信号方式の場合は、次の理由によっ
て個別線信号方式と同様の方法をとることができない。However, in the case of the common line signaling system, the same method as the individual line signaling system cannot be used for the following reasons.
すなわち共通線信号方式においては、網内のすべての交
換局に対してそれぞれ異なる信号局コードが局番号とし
て付与されるとともに、対向する２局間の通話回線にも
それぞれ異なる回線番号が付与され、かつ２局間におい
て回線番号が一致している必要がある。In other words, in the common line signaling system, different signal station codes are assigned as station numbers to all switching stations in the network, and different line numbers are assigned to the communication lines between two opposing stations. In addition, the line numbers must match between the two stations.
このためもしも２局間で信号局コードの設定を誤ると通
話回線は使用不可能状態となり、また信号局コードの設
定が一致していても回線番号の設定を誤れば、通話回線
は使用可能となるが接続時通話が不可能となる。Therefore, if the signal station code is incorrectly set between two stations, the telephone line will become unusable, and even if the signal station code settings match, if the line number is incorrectly set, the telephone line will become usable. However, it becomes impossible to make a call when connected.

通線有意信号ユニットＭＳＵ中の着信局コードＤＰＣが
自局の信号局コードと一致しなくなるため、ＭＳＵは破
棄されてしまって接続操作を行うことができなくなる。If the opposing station is in a state where it is not possible to perform an opposing test, if you perform a loopback jumper on the MDF of the signal line to this opposing station to another signal line for this opposing station, the signal will be sent from any signal line and the signal will be sent from the MDF. Since the receiving station code DPC in the common line significant signal unit MSU received after being looped back to another signal line does not match the signal station code of the own station, the MSU is discarded and connection operations cannot be performed. become unable.
このような問題点を解決する手段として、対向試験を行

局コードＤＰＣが登録した信号局コードと一致する場合
には、自局着信信号として取り扱う方法が考えられ、特
開昭６１−２３６２６２号によって公開されている。As a means to solve such problems, the terminating station code of the opposite station that cannot perform the opposing test is registered as one of the own station identification codes, and the terminating station code DPC in the received MSU is registered. If the received signal station code matches the received signal station code, a method is considered in which the signal is handled as an incoming signal from the local station, and this method is disclosed in Japanese Patent Application Laid-Open No. 61-236262.

線捕捉試験は行い得ても、呼接続のためのＭＳＵ送受信
による呼の接続と通話確認までは行い得ないという問題
点がある。However, in the above method, firstly, there is a problem that the operation of registering the own station identification code one by one is troublesome, and secondly, there is no consideration of the line number CIC value in the receiving MSU. Although it is possible to perform an acquisition test, there is a problem in that it is not possible to perform call connection and call confirmation using MSU transmission and reception for call connection.

になる。In other words, each of the two call lines looped back on the MDF has a line number CIC, and if one of them is captured and a trunk line call is made, the MSU of the call connection request accompanying the call will be the call line number. any one of the signal lines corresponding to
The signal is sent to the opposite station using a signal line, but it is looped back on the MDF and received by the own station via another signal line. received M
The terminating station code DPC in the SU is registered as the own station identification code, so it is analyzed, or at this time, the line number crc in the MSU indicates the value of the line that was captured, so the analysis processing unit This will be interpreted as a call collision, and the line will be released.
そのため自局内の伝送路障害等によって通話が不可能な
通話回線があったとしても、対向試験を行うまでは障害
を検出できないことになる。Therefore, even if there is a communication line in which communication is impossible due to a transmission path failure or the like within the own station, the failure cannot be detected until a peer test is performed.

The purpose is to provide a test method in the method.
