Telecommunications Technologies

Duration: 2 days.

La formation est aussi disponible en français.

Other courses: DNS Training, LDAP Training.

The world of telecommunications changed significantly with the introduction of Common Channel Signalling System #7 (SS7) and Advanced Intelligent Networks (AIN/IN). As a consequence of the SS7/AIN model's flexibility and power the architecture it is now, universally, the basis of value-added service enhancement on Cable and Mobile networks as well as the classic PSTN. With the rollout of high speed, feature rich 2G and 3G platforms todays Mobile networks offer unparalled opportunities for new and exciting business applications. SIGTRAN, by enabling extension of the SS7 network into the IP (Internet) world, is now THE key technology to facilitate development of value-added services for the PSTN, VoIP, Cable and Mobile networks. As all the service providers move toward a triple play world, the imagination may become the limiting factor in service development.

Description

Telecommunications Technologies is not a bits and bytes course but rather gives students an understanding about how all the pieces fit together and how they can be leveraged into business opportunities. Students learn about the growth and development of the PSTN, Cable, Mobile and Internet worlds.

SS7 and SIGTRAN protocols, being critical infrastructure, are covered in sufficient detail to enable appreciation their capabilities and power while extensive use is made of call animation scenarios to enable visualization of where, and how, value-added call processing can be used to leverage the business opportunities. VoIP (SIP) functionality is described and mapped onto its equivalent functionality in the traditional telephony world (Mobile, PSTN). At the end of the course students design, and outline the implementation of, value added services for PSTN, Mobile, Cable and VoIP networks.

Audience:

The course is designed for marketing, planning and business development personnel working within the Service Provider and equipment supplier industries for VoIP, Cable, Mobile or the PSTN, together with those who need a thorough understanding of the architecture and business opportunies available within the current telecommunications environment. A reasonable understanding of computing or telecommunications systems is a prerequisite for the course.
