line Attributes of lines (cables) used with the radio’s T1 or E1 Interface.
This command is used to set or display the internal pulse template selec-
tion used by the LEDR interface to compensate for signal distortion cre-
ated by various lengths and types of interface cables.
The
[linelist] variable represents a list of line interfaces. It can consist of
a single line number or line name, a comma-separated list of line num-
bers or line names, a range of line numbers (i.e., 1–4), or if linelist is not
given all lines will be displayed. See Table 19 on Page 59 for a list of
line numbers.
Usage For T1:
line [linelist] [cable length<0–4>] [spec]
T1 interfaces require setting of a minimum of two variables: ITU cable
specification and cable length. Table 21 shows the specification options
and Table 22 lists values used for various lengths of standard 100 Ω
twisted pair cables
Table 21. ITU Cable Specifications—Subcommand [spec]
Usage For E1: line [linelist] [spec]
The only cable specification needed for E1 is the ITU cable type.
Table 23 lists the specification values for two standard 120 Ω ITU-T
G.703 cables
