What does T4 (signal) represent?

T4 (signal) is a high-order trunk signal in the North American T-carrier hierarchy used for multiplexing lower-order channels at about 274.176 megabits per second, primarily in legacy telecom backbone links.

What is Firewire (IEEE-1394) used for?

Firewire is a standardized serial bus interface for high-speed data transfer between devices, often used for digital camcorder connections, external hard drives, and professional audio equipment.

Can I directly connect T4 (signal) equipment to Firewire devices?

No, due to differences in electrical and protocol standards, direct connection is not possible without proper interfacing or conversion equipment.
