What does converting from modem (14.4k) to STM-4 (signal) mean?

It means translating low-speed dial-up modem data transfer rates into equivalent high-speed STM-4 optical transport units used in telecom networks.

Why would I need to convert modem speeds to STM-4 units?

Users convert to integrate legacy modem data streams with modern synchronous digital hierarchy infrastructure for better network management and capacity planning.

Does the conversion account for data transmission overhead?

No, the conversion reflects nominal maximum bit rates and does not consider protocol overhead or real-world throughput variations.
