Description
Use the T1 Framer core in communication applications including multiplexing equipment, high-speed computer links, Internet access points, video conferencing, and video streaming.
The T1 Framer core provides T1 framing using the ESF format. The framer also provides clock synchronization from the system clock to the T1 clock for the data stream. The framer accepts 8-bit timeslot data presented to it following a timeslot request from the framer. The framer also provides a framing indicator for timeslot alignment.
