Signalling Server
?It controls all SS7 applications in the point of hardware and software.
?It uses NewNet Connect7 control cards. This card runs SS7 functions up to TCAP level.
NETWORK ARCHITECTURE
In the Canvas Unified Messaging many regional access servers are controlled and supported by central servers.. Access server runs F-SMS and Voicemail applications. Turk Telecom subscriber calls are connected to access server. Access server behaves as a telephone switch in Turk Telecom network. Signalling and media access is provided by HP Open Call Media Platform (OCMP). Pre-paid charging server is developed by Telenity. Master LDAP servers are also located in central servers.
SS7
SS7 or Signalling System Number 7 is a set of protocols that describes a means of communication between telephone switches in public telephone networks. SS7 is a highly sophisticated and powerful form of Common Channel Signalling (CCS). The use of out-of-band signalling procedures offers considerable benefits over and above other signalling methods.
Signalling
In any network, the definition of signalling is the exchange of information. In a telecommunication network, signalling is the exchange of information that relates to the establishment and control of connections, including management.
Today most transmission between telephone exchanges is digital, but in some cases signalling operates on specifications developed for analogue exchanges. The exchanges in these networks use Channel Associated Signalling (CAS). The CAS restricts signalling to the PCM link in which the telephone connections take place.
GENERALIZED SYSTEM OF THE EXCHANGES AND SERVERS
The voltage on the voice information of the telephone lines is on the order of 250 MV. During the conversation, this is about 5-10
I have found a report about Turktelekom which is written by O. Hasdeniz. He has performed his EE 300 Summer Practice in Turk Telecommunication. I want to share that document with you. And i’m sure he will be a great engineer int he future.
For nearly 165 years has Turk Telecom been working to supply modern communication opportunities to the subscribers. This effort is continuing today based on the same ideal. With the aim of providing modern technologies, Turk Telecom directed itself to international goals from national goals with its customer-oriented approach and qualified services. Turk Telecom is one of the biggest companies in the world, having the information and experience well enough to compete in the national and international communications markets. It is a decentralized company which has one general directorate and 81 administrative provincial directorate, one for each administrative provincial.
The 21st Century appears to be an increasingly benevolent era, particularly for telecommunications products and services. Consumers and businesses are being offered an ever widening range of goods, for a ticket prize of zero. Or are they?
WiMAX (Worldwide Interoperability for Microwave Access) is a new standard that lean on the IEEE’s 802.16 wireless communication standard specification and it provides services to faster and wider areas when it is compared with 802.11 group standards (WiFi).Especially it is expected that it will provide wideband internet services to the areas that cable and DSL services cannot reach. WIMAX presents lots of advantages compared with other wireless technologies. WIMAX multi road choice and the property of distribution of delay makes it present a good perfonnance even it is out of the view point of user’ base station.
It is a very positive issue that the number of universities has been increasing, since they support acedemical works and provide the opportunity to raise university graduate staff. Howe-
ver, after graduation we are mostly to face with a new trouble: Insufficient job opportunuties.
