-
Supporting transport of legacy E1 circuits in optical network engineering
-
Facilitating granular bandwidth management and provisioning in synchronous optical networks
Tips & Best Practices
-
Confirm that the H11 unit is appropriate for your measurement context, as it is not standardized
-
Use this conversion primarily within telecommunications involving SONET/SDH networks
-
Validate the conversion applies to your specific network architecture and use case
Limitations
-
H11 is not a standardized or widely recognized data transfer unit, which may create confusion
-
Conversion relevance is constrained to specialized telecom scenarios involving SONET/SDH
-
The fixed 1 H11 to 0.75 VT2 payload rate is specific to certain mapping scenarios and not universally applicable
Frequently Asked Questions
-
What is H11 used for in data transfer measurements?
-
H11 is not a standard unit; it sometimes refers to theoretical quantities in data transfer but is not common in practice where bits or bytes are standard.
-
What does Virtual Tributary 2 (payload) represent?
-
It is a container in SONET/SDH networks sized to carry a 2.048 Mb/s PDH/E1 channel, allowing low-rate signals to be multiplexed into higher-rate optical frames.
-
Why convert from H11 to Virtual Tributary 2 (payload)?
-
To align a non-standard unit with a recognized SONET/SDH payload format that supports legacy TDM circuit transport and optical network provisioning.
Key Terminology
-
H11
