What does one ISDN (single channel) represent in data transfer rate?

One ISDN (single channel) corresponds to a data rate of 64 kilobits per second, typically used for voice or user data in telecommunication systems.

What is a Virtual Tributary 2 (VT2) signal?

A Virtual Tributary 2 is a SONET/SDH sub-rate signal with a 2.048 Mbps payload, designed to carry E1 channels within higher-rate SONET/SDH frames.

Why convert from ISDN (single channel) to VT2 signals?

Converting facilitates mapping legacy ISDN channels onto SONET/SDH networks, aiding in capacity planning and equipment configuration for telecom infrastructure.
