Table
Standardized digital transmission rates for the synchronous digital hierarchy (SDH), the synchronous optical network (SONET), and the optical carrier (OC) hierarchy*
SDH system SONET system OC level transmission rate in megabits per second (Mbps) or gigabits per second (Gbps) maximum voice channels per circuit
STS-1 OC-1 51.84 Mbps 783
STM-1 STS-3 OC-3 155.52 Mbps 2,349
STM-4 STS-12 OC-12 622.08 Mbps 9,396
OC-24 1,244.16 Mbps 18,792
STM-16 STS-48 OC-48 2.4888 Gbps 37,584
*SDH is the transmission hierarchy established by the International Telegraph and Telephone Consultative Committee (CCITT); SONET and OC are transmission hierarchies established by the American National Standards Institute (ANSI).
