Final Answer:
The speed of an E1 connection in legacy speeds in Europe because an E1 line operates at a rate of 2.048 Megabits per second (Mbps). Therefore the correct option is 2.048Mbps.
Explanation:
In legacy telecommunications, an E1 connection in Europe typically operated at a speed of 2.048Mbps. E1, part of the European digital hierarchy, was a standard for digital transmission of voice and data services.
It consisted of 32 time slots, each capable of transmitting 64 kilobits per second (Kbps), resulting in a total aggregated bandwidth of 2.048Mbps. These connections were widely used for various telecommunications purposes, including voice calls, data transmission, and internet services across Europe.
E1 connections were foundational in establishing digital communication networks and were commonly utilized by telecommunications providers, businesses, and enterprises for reliable and high-speed data transmission.
Therefore the correct option is 2.048Mbps.
