The technology is known as high-bit-rate digital subscriber line (HDSL). HDSL employs a 2B1Q modulation technique across the same types of pairs traditionally encountered with metallic T1 deliv- ery systems. HDSL satisfies the telco distance requirements without the use of repeaters. Symmetric Digital Subscriber Loop (SDSL) is HDSL using only one pair. This provide
