Examples
-
2 STM-64 (signal) equals 1,382,400 modem (14.4k)
-
0.5 STM-64 (signal) equals 345,600 modem (14.4k)
Common Use Cases
-
Comparing optical transmission and dial-up modem speeds
-
Integrating modern SDH/SONET systems with legacy dial-up technologies
-
Analyzing legacy telecommunications or network equipment compatibility
Tips & Best Practices
-
Use the tool for straightforward unit conversions without overhead considerations
-
Understand that speed differences are large and direct data transfers may require bridging equipment
-
Apply conversions when legacy and modern telecom systems need to be compared or integrated
Limitations
-
Does not consider protocol overhead or error correction factors
-
Real-world transfer speeds may vary from theoretical values
-
Modem (14.4k) speeds are much lower, requiring intermediary technologies for actual data exchange
Frequently Asked Questions
-
What does STM-64 (signal) represent?
-
STM-64 is a synchronous digital hierarchy signal with a line rate near 10 Gbit/s, used in high-capacity core and long-haul fiber networks.
-
What is a 14.4k modem used for?
-
A 14.4k modem enables dial-up connections over analog telephone lines, commonly for early internet access, remote sessions, and legacy data communications.
-
Why convert STM-64 to modem (14.4k)?
-
To relate very high-capacity optical network rates to much lower dial-up modem speeds for comparison, integration, or legacy system analysis.
