What does STS3 (signal) represent in data transfer?

STS3 (signal) is a SONET digital transmission signal with a line rate of 155.52 megabits per second, used for multiplexing multiple lower-rate channels in synchronous optical or electrical networks.

What is ISDN (dual channel) in telecommunications?

ISDN (dual channel) refers to using both 64 kbit/s B channels of an ISDN Basic Rate Interface together to provide about 128 kbit/s throughput, used for voice and data services.

Why convert from STS3 (signal) to ISDN (dual channel)?

This conversion helps compare or translate high-capacity SONET data rates into legacy ISDN channel equivalents, useful for network planning and equipment configuration.

Is the conversion precise for hardware implementation?

No, the conversion is an approximation for comparison as ISDN is a service-level descriptor and STS3 rates are much higher, so direct hardware equivalence is impractical.
