NOTE: With digital service, there is always confusion about what the term line denotes. Since there are

actually multiple lines in one digital line, the more encompassing term for this connection is span, or

in the case of this networking document, link. A link (or span) usually refers to the single 4-wire T1/E1

or PRI connection from the service provider. A link (or span) could consist of as many as twenty-three

individual lines depending upon the type of T1/E1 or PRI service. To define the term line further when

used with T1/E1 or PRI service, this networking document uses the term channel to refer to the

individual lines in a link.

To restate these terms:

Link (or Span) = single 4-wire T1/E1 or PRI connection consisting of as many as twenty-three

channels.

Channel = individual lines in a link.
