What does converting from Modem (14.4k) to Virtual Tributary 1 payload achieve?

It enables mapping low-speed analog modem data rates into digital containers used in high-speed optical transport networks.

Can this conversion be used for live data transmissions?

No, due to speed differences and timing requirements, this conversion is intended mainly for planning and network design.

Why is there overhead when converting low-rate signals to VT payloads?

Because Virtual Tributary payloads are designed for higher bit rates, mapping lower speeds involves extra alignment and synchronization overhead.
