How many customers are served by one E1?

Answer 1

one E1 link can be splitted into 32 links by internal boards in BSC. one link generates 64Kpbs so 32 links produces 2.048Mbps signal ( 32x64Kbps=2040Kbps). 1 E1 link splitted to 32 links by boards, and each link has got 8 Timeslots, totally 32x8=256 Timeslots, Means 256 Users can utilize at a time. But, In practice people may use packet calls also, So the whole frame structure cannot be given to Voice circuits. Keeping this in mind we again split the links into Ports such as primay and secondary. primary which is given to Circuit switching and secondary for packet switching. We can assign the timeslots for CS & PS manually depends on the services and operator demand. Eventhough 256 users can utilize, we are using apprx 128 by one E1 link. (16x64Kbps). The circuit switching timeslot figure can be more than 128 sometimes because packet calls requires higher data always. So many of the service providers can have more timeslots for voice than packet switching technique. hope am right. if you find the mistakes pl correct me. Thank you !!!!
