What Is This Tool?
This unit converter enables you to change measurements from STS3c (signal), a high-bandwidth SONET electrical transport signal, into Virtual Tributary 6 (payload), a smaller SONET/SDH tributary container used for carrying lower-rate legacy payloads.
How to Use This Tool?
-
Enter the quantity of STS3c (signal) you want to convert
-
Select STS3c (signal) as the from-unit
-
Select Virtual Tributary 6 (payload) as the to-unit
-
Initiate the conversion to get the equivalent Virtual Tributary 6 (payload) value
-
Use the result for network design or service integration purposes
Key Features
-
Converts data transfer units within SONET/SDH frameworks
-
Supports conversion from STS3c (signal) to Virtual Tributary 6 (payload)
-
Displays equivalent values based on a fixed conversion rate
-
Browser-based tool requiring no installation
-
Useful for telecom network planning and legacy system integration
Examples
-
1 STS3c (signal) equals 25.92 Virtual Tributary 6 (payload)
-
2 STS3c (signal) equals 51.84 Virtual Tributary 6 (payload)
Common Use Cases
-
Provisioning high-bandwidth backbone or leased-line circuits at 155.52 Mbps
-
Transporting Ethernet or Packet-over-SONET as a single virtual circuit
-
Interconnecting metro or backhaul SONET equipment for aggregated traffic
-
Mapping legacy PDH circuits such as DS1/E1 over SONET rings
-
Grooming and multiplexing lower-rate services into higher-rate payloads
-
Carrying voice or low-bandwidth customer circuits in larger SONET/SDH systems
Tips & Best Practices
-
Ensure selections are within the SONET/SDH framework for accurate conversion
-
Use the tool to plan efficient multiplexing and grooming of traffic
-
Double-check unit selections to avoid misinterpretation of data rates
-
Keep in mind protocol overheads may affect real-world throughput outside the conversion
-
Employ this tool for both legacy and modern telecom network integration
Limitations
-
Conversion assumes standard payload sizes without accounting for overhead or protocol variances
-
Applicable only within SONET/SDH transport technologies
-
May not apply to non-SONET systems or protocols
Frequently Asked Questions
-
What does STS3c (signal) represent?
-
STS3c (signal) is a SONET electrical transport signal representing a contiguous payload formed by concatenating three STS-1 channels with a data rate of 155.52 Mbit/s.
-
Why convert STS3c signals to Virtual Tributary 6 payloads?
-
Converting STS3c signals to VT6 payloads helps break down high-bandwidth signals into smaller tributaries, enabling integration of lower-rate legacy services within synchronous networks.
-
Is this conversion valid for non-SONET transport technologies?
-
No, this conversion applies only within the SONET/SDH framework and may not be valid for non-SONET systems.
Key Terminology
-
STS3c (signal)
-
A SONET electrical transport signal concatenating three STS-1 channels, with a data rate of 155.52 Mbit/s, used to carry high-bandwidth streams without byte-interleaving.
-
Virtual Tributary 6 (VT6)
-
A standardized SONET/SDH sub-container used to carry fixed-size lower-rate plesiochronous or PDH payloads within the larger synchronous payload frame.
-
SONET
-
Synchronous Optical Network, a standardized digital communication protocol used to transmit multiple digital bit streams over optical fibers.
