What does ISDN (dual channel) represent in data transfer?

ISDN (dual channel) refers to the combined use of two 64 kbit/s bearer channels in an ISDN Basic Rate Interface, providing approximately 128 kbit/s throughput.

What is a T3 (signal) line used for?

T3 (signal), also known as DS3, is used for high-capacity digital transmission carrying multiplexed voice and data at about 44.736 Mbps, ideal for enterprise leased lines and carrier backbones.

Why convert ISDN (dual channel) to T3 (signal)?

Converting helps translate smaller-scale ISDN rates into high-capacity T3 equivalents, useful for comparing local links with backbone connections and supporting network planning.
