Hi Abdul,

 You can find this information on Table 2 of Cisco's Datasheet and the link is below:

From the website:

On-hook voltage

-44V

Off-hook loop current

25 mA (maximum) for short-loop-length port 35 mA (maximum) for long-loop-length port

Ring voltage

54 Vrms into 5 ringer equivalence numbers (RENs) at zero-loop-length port (balanced) (short-loop-length port) 62 Vrms into 2 RENs at zero-loop-length port (balanced) (long-loop-length port)

Ring frequency

20, 25, 30, and 50 Hz
