What Is This Tool?
This converter helps users translate data transfer measurements from Virtual Tributary 2 (payload), used in SONET/SDH networks, to ISDN (dual channel), a telecommunication data-transfer configuration. It supports planning and compatibility for legacy TDM and ISDN services.
How to Use This Tool?
-
Enter the value in Virtual Tributary 2 (payload) units you want to convert.
-
Select Virtual Tributary 2 (payload) as the source unit and ISDN (dual channel) as the target unit.
-
Click the convert button to see the equivalent number of ISDN (dual channel) units.
Key Features
-
Browser-based, easy-to-use unit converter for data transfer units.
-
Converts Virtual Tributary 2 (payload) units into ISDN (dual channel) units.
-
Supports telecommunications infrastructure and legacy TDM network management.
-
Provides conversion based on a fixed ratio of 1 VT2 (payload) equaling 16 ISDN (dual channel).
Examples
-
1 Virtual Tributary 2 (payload) equals 16 ISDN (dual channel).
-
3 Virtual Tributary 2 (payload) equals 48 ISDN (dual channel).
Common Use Cases
-
Converting SONET/SDH TDM channel capacities to ISDN basic rate configurations for planning.
-
Managing legacy telecommunications network provisioning involving PDH and SDH systems.
-
Supporting small-office or home-office network setups integrating ISDN dual channel services.
-
Facilitating remote LAN access or backup links that utilize bonded ISDN B channels.
Tips & Best Practices
-
Ensure you understand the specific telecommunications context before applying conversions.
-
Use this converter for capacity planning and service compatibility within legacy network setups.
-
Remember that ISDN (dual channel) represents a service-level descriptor, not a standard SI data rate.
-
Check your equipment's channel bonding capabilities as they may affect actual throughput.
Limitations
-
ISDN (dual channel) is a non-SI unit describing a telecommunication service configuration, so conversion does not reflect a strict physical data rate equivalence.
-
Variations in channel bonding implementations and granularity affect practical data throughput.
-
This conversion applies primarily within legacy telecommunication infrastructure contexts and may not be suitable for other data transfer scenarios.
Frequently Asked Questions
-
What does 1 Virtual Tributary 2 (payload) represent?
-
It is a SONET/SDH virtual tributary container designed to carry a 2.048 Mb/s PDH/E1 channel, often used for mapping lower-rate signals into higher-capacity optical frames.
-
How is ISDN (dual channel) defined in this context?
-
ISDN (dual channel) refers to using both 64 kbit/s B channels of an ISDN Basic Rate Interface bonded together to provide around 128 kbit/s of combined throughput.
-
Why convert from Virtual Tributary 2 (payload) to ISDN (dual channel)?
-
Users convert to translate between higher-capacity SONET/SDH TDM channels and lower-capacity ISDN configurations for compatibility and capacity planning in legacy networks.
Key Terminology
-
Virtual Tributary 2 (payload)
-
A SONET/SDH virtual tributary container sized to carry a 2.048 Mb/s PDH/E1 channel, enabling multiplexing of lower-rate time-division signals.
-
ISDN (dual channel)
-
A telecommunication data-transfer configuration using both 64 kbit/s B channels of an ISDN Basic Rate Interface bonded to deliver about 128 kbit/s throughput.
-
Channel Bonding
-
The technique of combining multiple channels in parallel to increase overall data transfer capacity.
