What does OC1 stand for in telecommunications?

OC1 refers to Optical Carrier level 1, a SONET optical transmission rate of 51.84 megabits per second used for framing and multiplexing optical networks.

What is a T1C signal?

T1C is a North American digital carrier signal transmitting 1.544 megabits per second by multiplexing 24 voice or data channels over a DS1 frame.

Why convert OC1 to T1C?

Converting OC1 to T1C helps translate high-capacity optical rates into equivalent numbers of lower-rate T1 digital channels, aiding network integration and planning.
