  High bit-rate Digital Subscriber Line
  HDSL
  
     <communications, protocol> (HDSL) A form of Digital Subscriber Line
     , providing T1 or E1 connections over two
     or three twisted-pair copper lines, respectively.  Unlike
     most other forms of DSL HDSL is not a typical consumer
     service, it's used mostly to replace traditional T1/E1
     connections, such as connecting PBXes to telco offices.
     The advantage of HDSL over the Alternate Mark Inversion line
     coding scheme traditionally used on T1/E1 lines is that it
     requires about an order of magnitude lower bandwidth to carry
     the same traffic.
