What Is This Tool?
This converter transforms data measurements from E.P.T.A. 1 (payload), a protocol-specific payload unit, into STM-16 (signal), a standardized Synchronous Digital Hierarchy signal level used in carrier networks. It facilitates understanding and planning bandwidth and network capacity by translating between protocol payload sizes and optical signal levels.

Tips & Best Practices
-
Use this converter as a guide for estimating equivalent SDH signal capacity requirements.
-
Combine conversion results with network-specific details when planning bandwidth.
-
Be aware that the conversion reflects throughput equivalence without protocol overhead.
-
Validate converted values with actual network measurements to ensure accurate provisioning.
-

Limitations
-
Conversion accounts for payload throughput but excludes protocol overhead and framing differences.
-
Real network conditions and encapsulation may affect actual transport capacity needs.
-
E.P.T.A. 1 (payload) is protocol-specific and may not represent all user data types or protocols.
Frequently Asked Questions
-
What does E.P.T.A. 1 (payload) represent?
-
