Main advantage of IPTV is interactivity of video services and wide range of additional services (Video on Demand (VoD), TVOIP, Time Shifted TV, Network Personal Video Recorder, Electronic Program Guide, Near Video on Demand). Except for video services, features of IP protocol can also ensure the rendering of much wider service package – including the interactive and integrated services.
Headend and subscriber equipment that allows providers of wideband services to provide reliable high-speed services of data transmission and access to Internet for users. Besides, in this section you can introduce yourselves with automated system of calculation and monitoring for DOCSIS networks, that allows to keep traffic records, money and services (billing system functions), as well as allows to control DHCP server service, TFTP service.
To solve different tasks of communication arrangement in Ethernet networks different types of switches are produced- from the simplest up to managed and unmanaged switches
Designed to build the Ethernet networks according to the SWDM technology, where intermediate nodes need a diversion of some Ethernet channels and adding the others.
All media converters are divided for convenience into managed and unmanaged ones. In its turn, they can be subdivided into two-fiber converters (Rx-Tx) and single-fiber ones (WDM) with single-mode (SM) and multi-mode (MM) optics. As well when selecting converters one should consider type of optical connector (ST, SC etc). For serviceability of big number of media converters once can use chassis that allow you to simplify connection of converters, increase reliability and serviceability. They allow unloading your server from big number of power units. Some chassis models allow arranging stand-by supply. All chassis models maintain “hot replacement” mode of converters
PON technology allows with using one fiber to arrange completely passive optical access network for 32 units in radius of 20 km, providing Ethernet service in each unit. The main point of PON technology is that between OLT and ONTs is created a fully passive optical network which have a tree topology. In the intermediate tree terminals are located passive optical splitters – compact devices not requiring for supply and maintenance.
Range of VoIP devices is displayed with several equipment series different both as per number of ports and as per extension possibilities and functional possibilities. One should mark equipment models intended for operation with Skype.
