Answer: 55 Kbits/sec - 64 KBits/sec
Explanation:
Signal System 7 (SS7) is used one of the protocols used for communication for mobile operators and it uses circuit switching. As it uses circuit switching it transfers data using a dedicated channel and hence more comparatively faster. It communicates and sends signals among Service Switching (SSPs), Signal Transfer Points (STPs), and Service Control Points (SCPs) using a different path apart from the data transfer path.
The data transfer rate which is the transfer of data among the various network elements is 55 Kilo bits/sec - 64 kilo bits/sec.
