What does T1C (signal) represent?

T1C (signal) is a T1 digital carrier signal used in North American telecommunications transmitting at 1.544 megabits per second by multiplexing 24 channels of 64 kb/s into a DS1 frame.

What is ISDN (dual channel)?

ISDN (dual channel) involves using both 64 kbit/s B channels of an ISDN Basic Rate Interface in parallel to provide a combined data rate of about 128 kbit/s.

Why convert from T1C (signal) to ISDN (dual channel)?

Users convert between these units to compare the equivalent data transfer capacity between large multiplexed digital signals and smaller, bonded ISDN channel configurations typically used in legacy systems.
