-
0.5 STS24 (signal) converts to 360 Virtual Tributary 1 (signal)
Common Use Cases
-
Managing carrier backbone or long-haul optical links typically referenced as OC-24
-
Aggregating multiple lower-rate circuits such as T1/E1 or STS-1 between data centers
-
Providing backhaul for metro networks carrying Ethernet, voice, or legacy leased-line services
-
Breaking down high-rate signals into sub-channels for grooming and switching within SONET/SDH networks
Tips & Best Practices
-
Use this tool to facilitate efficient bandwidth utilization by managing sub-rate channels
-
Ensure network equipment supports the required grooming and switching capabilities for Virtual Tributaries
-
Consider standard SONET overhead and investigate payload limitations during planning
-
Apply this conversion when designing or maintaining SONET/SDH hierarchy in telecom networks
Limitations
-
Conversion assumes ideal SONET overhead; actual usable payload may be slightly less
-
Virtual Tributary counts depend on network device support for grooming and switching
-
Practical deployment requires attention to signal integrity, synchronization, and network architecture

Key Terminology
-
STS24 (signal)
-
A SONET synchronous transport signal formed by multiplexing 24 STS-1 channels, with a nominal rate of approximately 1.244 Gbit/s.
-
Virtual Tributary 1 (signal)
-
A logical sub-channel in SONET/SDH used to encapsulate lower-rate digital signals for independent grooming and switching.
-
SONET
-
Synchronous Optical Network, a standardized digital communication protocol used to transmit multiple digital bit streams over optical fiber.
