-
Use conversions to understand how SONET sub-channels compare to dial-up modem speeds
Common Use Cases
-
Mapping multiple lower-rate PDH/TDM circuits over SONET networks
-
Evaluating legacy modem download speeds in comparison with modern optical links
-
Bandwidth allocation and traffic grooming in SONET/SDH transport systems
-
Estimating data transfer capacity for mixed network environments

Tips & Best Practices
-
Ensure you understand the context of VT6 within SONET infrastructure when interpreting results
-
Use this converter to aid in realistic network planning across legacy and current technologies
-
Remember modem (28.8k) speed is an informal approximation and factors like connection quality affect actual throughput
-
Consider the conversion factor as a steady-state estimation, not accounting for line overhead
-
Validate conversions with actual measurements when possible for critical network design
Limitations
-
Conversion assumes steady data rates and does not include effects of line noise or protocol overhead
-
Modem (28.8k) throughput is an informal rate which varies with implementation and connection quality
-
VT6 is specific to SONET/SDH systems and may not directly relate to other network standards
-
The tool provides theoretical equivalences rather than real-time performance metrics
Frequently Asked Questions
-
What is a Virtual Tributary 6 (VT6) signal?
-
A VT6 is a standardized logical sub-channel in SONET networks used to transport lower-rate client signals within an STS‑1 payload, enabling efficient bandwidth grooming and multiplexing.
-
How accurate is the modem (28.8k) unit?
-
Modem (28.8k) is an informal label representing about 28,800 bits per second; actual throughput depends on connection quality and modem implementation.
-
Can I use this conversion for real-time throughput measurements?
-
No, the conversion provides a theoretical steady-state data rate equivalence and does not account for network conditions affecting real throughput.
