What Is This Tool?
This converter helps translate data transfer measurements from Virtual Tributary 6 (payload), a sub-container used within larger synchronous payloads in SONET/SDH networks, into ISDN (dual channel), which combines two ISDN bearer channels for data throughput. It supports understanding and managing data rates between distinct telecommunications technologies.

Tips & Best Practices
-
Verify the compatibility of SONET/SDH and ISDN equipment when performing conversions.
-
Use the tool to estimate data rate equivalencies for traffic grooming and network planning.
-
Remember this conversion is mainly relevant for legacy or hybrid telecommunications systems.
-
Account for possible variations in payload overhead and protocol implementations.
Limitations
-
ISDN (dual channel) is a service-level descriptor, not an exact SI unit, which can affect accuracy.
-
Differences in framing and protocol details in SONET/SDH and ISDN may influence real throughput.
-
This conversion is less applicable to modern IP-based or Ethernet networks.
-
Results represent theoretical equivalency and may not capture overhead or real-world variations.
Frequently Asked Questions
-
What does Virtual Tributary 6 (payload) represent?
-
It is a standardized virtual container within SONET/SDH systems designed to carry specific lower-rate plesiochronous/PDH payloads for grooming and multiplexing into larger optical frames.
-
How is ISDN (dual channel) defined?
-
ISDN (dual channel) uses both 64 kbit/s B channels of an ISDN Basic Rate Interface in parallel through channel bonding, providing a combined data transfer rate of about 128 kbit/s.
-
Why convert from Virtual Tributary 6 (payload) to ISDN (dual channel)?
-
Users perform this conversion to translate data rates between high-capacity SONET/SDH containers and lower-rate bonded ISDN services for traffic management and interoperability.
