What does OC1 represent in telecommunications?

OC1 is the base SONET optical transmission rate of 51.84 megabits per second corresponding to an STS-1 electrical signal.

What is a Virtual Tributary 2 payload?

A Virtual Tributary 2 (VT2) payload is a SONET/SDH container used to carry a 2.048 Mb/s PDH/E1 channel, enabling multiplexing of lower-rate TDM signals.

Why convert OC1 to Virtual Tributary 2 payloads?

Converting OC1 to VT2 payloads helps map high-rate optical signals into smaller granular channels for efficient transport and provisioning of legacy TDM circuits.
