What is another word for HDSL?
Pronunciation: [ˌe͡ɪt͡ʃdˌiːˌɛsˈɛl] (IPA) 
HDSL stands for High-bit-rate Digital Subscriber Line, which is a technology used to provide high-speed internet service over traditional telephone lines. Some synonyms for HDSL include Symmetric Digital Subscriber Line (SDSL), Very High Digital Subscriber Line (VDSL), and Asymmetric Digital Subscriber Line (ADSL). SDSL is similar to HDSL in terms of speed and reliability, but it offers symmetrical upload and download speeds. VDSL is faster than HDSL and can deliver both internet and television signals. ADSL is the most common type of DSL, offering high download but relatively lower upload speeds. Despite the differences, all of these DSL technologies rely on copper telephone lines to deliver internet services to homes and businesses.
