What Is This Tool?
This unit converter transforms data transfer rates from STS3c (signal), a high-speed SONET transport signal, into the legacy modem (1200) unit, which represents an early dial-up modem speed. It helps translate modern backbone throughput into equivalent older modem channel speeds for analysis and legacy system compatibility.

Frequently Asked Questions
-
What does STS3c (signal) represent?
-
STS3c (signal) is a SONET electrical transport signal with a gross data rate of 155.52 Mbit/s formed by concatenating three STS-1 channels.
-
Why convert to modem (1200) units?
-
Converting to modem (1200) units helps compare modern high-speed SONET circuits to legacy dial-up modem speeds for historical or compatibility analysis.
-
Is this conversion exact for all protocols?
-
No, the conversion is numerical only and does not account for differences in protocol overhead or link efficiency.
