For a long time, incumbent carriers tended to regard spc exchange, ddn, fr, atm and ip equipment as leading network elements. most often than not, the transmission equipment is only seen as supportive parts for those leading elements
長期以來,主體電信經營商都認為程式控制電話交換機、 ddn 、 fr 、 atm 、 ip等設備是作為網路的主體,而傳送設備僅認為是這些設備的配套。After the switching of the numbering mode, services can be displayed and configured on the basis of lucent s numbering mode. but at that time since there was no network - level nm in beijing telecom s transmission network and the lct ( pc - based element - level nm ) could display and configure services only on the basis of huawei s mode, the configuration mode needed to be modified manually when implementing interconnection to lucent s equipment and each adjustment had to be made according to lucent s numbering mode through the built - in cross connection function while configuring services
轉換后,即可按朗訊的編號方式在網管上顯示業務與配置業務。但當時北京電信的華為傳輸網未建立該網路級網管,而lct (基於pc的網元級網管)只能以華為公司的時隙編號方式顯示與配置業務,在與朗訊對接時需要人工修改配置方式,通過sdh設備的內置交叉功能在配置業務時按朗訊公司的編號方式一一調整。The conventional switching power supply usually use a diode rectifier followed by a bulk capacitor to convert ac voltage to dc voltage, resulting in the pulsating waveform of the input ac line current, low power factor ( generally 0. 65 ) and high harmonic line current
傳統的開關電源設備通常採用二極體橋來進行整流和一個較大的電解電容來進行濾波以實現輸入電壓的交直流轉換,導致輸入電流為一個很窄的脈沖波並含有較多的諧波分量,功率因數變低(通常只有0 . 65 ) 。The product is widely applied to telecommunication fitting exchanging equipments, telephone sets, cable televisions, computers, modem, various electronic, facilities, equipments, household electrical appliances, terminals of transmission units, electrical equipment and surge protection for power distribution system and so on. switching spark gaps have more extensive use
產品被廣泛應用於電信裝置交換設備電話機有線電視計算機數據機及各類電子設備儀器家用電器,傳輸裝置終端,電氣設備及配電系統電涌保護等方面,開關放電管主要用於點火裝置,例如汽車氙氣燈hid ,燃氣爐具,照明燈具等。In early 2000, beijing telecom tested interworking of the stm - 1 ports of ericsson s axe10, shanghai bell s p3s and huawei s cc08 with the transmission equipment and their connectivity with the communication network in operation, and successfully introduced stm - 1 equipment between the tandem exchanges and between some end exchanges and exchanges. besides, it cut over dozens of stm - 1 paths
2000年初,北京電信對愛立信的axe10 、上海貝爾p3s和華為cc08交換機的stm 1埠直接與傳輸設備進行互通測試,與運行的通信網路相連測試,並成功地在匯接局間和部分電話端局交換局之間引入stm 1介面設備,並開通了幾十條stm 1通路。With their digital distribution frames connected to the transmission equipment, such ports provide trunk paths at 2 mbs by means of hf cable
利用高頻電纜在2mbits速率上,經數字配線架( ddf )與傳輸設備相連接,提供交換機間的中繼通路。The tandem switch is directly connected to 10 g transmission equipment via two 155 mbs coaxial cables, saving adm41 or adm161 equipment
匯接交換機直接與10g傳輸設備經過2條155mbits的同軸電纜進行連接,節省了adm41或adm161設備的使用。As a result, at all these connection points, the two coaxial cables are connected to different transmission equipment, sharing the traffic load from the tandem switch to a given end exchange, with half of the respective trunk circuits put into use, ensuring network safety. for such connectivity, see figure 4
因此,在所有的同軸電纜連接處,都採用兩條同軸電纜接到不同的傳輸設備的方法,將匯接交換機到某一端局的話務量在這兩條同軸連接上進行負荷分擔,中繼電路各開一半,從而保證網路的安全性。After the introduction of pcm, a pair of fiber can transmit at the rate of 34 mbits, which is equivalent to 480 circuits. now, digital trunks have been introduced, with a port rate of 2 mbits, which is equivalent to 30 circuits
在pcm出現之後,一對光纖可傳送34mbits ,相當於480條電路;現交換機中繼設備數字中繼,每埠速率2mbits , 30條電路。Optical relay network technoiogy is to buiidup various teiephone networks by the flexible sdh transmission equipment working with stored program control switches. at present, it has been adopted by most of telecom operators in iocal networks of pstn and becomes an eff6ctive solution to imp the operation cost, improve the qos, as well as faciiitat6 the oam
光中繼組網就是利用同步數字體系( sdh )傳輸設備本身組網的靈活性來配合程式控制交換機組成各種電話網路,在目前的公共電話交換網路( pstn )中的本地網路中,較多地被電信運營商所採用。Digital distribution frame is suitable for the distribution and connection of digital terminal equipment or exchanger, with performance of circuit redeploy, connection and test
數字配線架適用於傳輸碼率為2 - 155mb s以下的數字終端設備或程式控制交換機的數字信號的配線與轉接,具有電路調度轉接和測試等功能。Before the 1990s, the digital transmission equipment was based on the technical standards of plesiochronous digital hierarchy ( pdh ). in order to connect the switch to pdh transmission equipment, the switch side needs lots of terminal equipment of the primary rate, i. e., 2048 kbits ( 2m ) switching terminal circuits in compliance with itu - t standards ( e. g. s1240 s dtm trunk module and axe10 s etc module ) and ansi - standard - based 1544 kbits ones
在90年代初期以前,數字傳輸設備是建立在pdh ( plesiochronousdigitalhierarchy )技術標準上,為了連接交換機到pdh傳輸設備上,在交換機側需要大量的符合基群速率的終端設備,即符合itu - t標準的2048kbits ( 2m )交換終端電路(如s1240的dtm中繼模塊, axe10的etc模塊)和符合ansi標準的1544kbits交換終端電路等。E - government construction especially stresses standardization and interchange. the electronic document interchange becomes the most important medium in the contact and communication among governmental offices due to its important role in the governmental office. in the early stage of edi, the expensive special network must be adopted and the specific hardware and software must be purchased while considering the data security and its transmission
早期的電子資料交換作業在考慮到資料的安全性與傳送速度因素下,需採用成本高昂的專用網路,並購置特殊的軟硬體設備,才能構建一個完整的電子資料交換系統,這樣的電子資料交換機制實現和使用成本非常昂貴,而且用來進行交換的資料格式相當復雜不具彈性。Generally speaking, information appliances have exceeded the traditional electrical home appliances concept, including all the information processing equipments that can exchange the information through the network system, such as home pc, roof box, hpc, dvd, wireless data communication equipments ( dce ), palmtop computers, pda, video game equipments, webtv, etc. they are the combination of 3cs ( computer, communication and consumer electronics )
廣義來說,信息電器已突破傳統家電概念,包括家用pc 、機頂盒、 hpc 、 dvd 、無線數據通信設備、掌上電腦、 pda 、視頻游戲設備、 webtv等所有能通過網路系統交換信息的信息處理設備。它也是3c ( computer 、 communication 、 consumerelectronics )合一的產物。For the convenience of operation, it is necessary to number 63 e1s. since there are no definite speculations about the corresponding relationship between the e1 numbers and the positions of the tributary channels in the optical circuit, vendors number the e1s on the basis of before and after multiplexing. hence two e1 numbering methods. while difference in numbering will not cause problems in interconnectivity of equipment, it will cause inconvenience of maintenance
在使用中為了操作方便需要對63條e1進行編號,由於在itu - t的規范中,沒有具體對e1的編號和支路在光路中的位置的對應關系作明確的規定,所以不同設備供應商分別按照復用前和復用后兩種方式對e1進行編號,因此也就出現了兩種e1的編號方式,編號不一致不會造成設備對接問題,但是會造成維護的不方便,一旦分配電路時出現人為的差錯,糾正起來非常困難,因此在實施前統一不同交換機和傳輸設備的編號是十分重要的工作。On the other hand, in networking trunk circuits, we should consider using dual coaxial cable connections as many as possible via different transmission equipment, and enable the trunk circuits of a given switch to be shared by the two routes
另一方面,在中繼電路的組網上,也要考慮盡可能採用雙同軸電纜連接、經不同傳輸設備的連接方式,將到某一交換機的中繼電路分擔在這兩條路由上。Alarm systems. alarm transmission systems and equipment. part 1 - 3 : requirements for systems with digital communicators using the public switched telephone network
報警系統.報警傳輸系統和設備.第1 - 3部分:使用公共交換電話網帶數字發報機的系統要求Alarm systems. alarm transmission systems and equipment. part 2 - 3 : requirements for equipment used in systems with digital communicators using the public switched telephone network
