factors. PATHTF overrides RSIZE, SPEED, SPEEDK, or LINETF, whereas LINETF
overrides RSIZE, SPEED, and SPEEDK (but not PATHTF). Either RSIZE, SPEED,
SPEEDK, LINETF, or PATHTF must be set, else the line handler will display a
configuration error.
The formula to convert from SPEED to LINETF is:
LINETF = (224000 + (SPEED / 2)) / SPEED
Refer to Setting Time Factors on page 18-23 for more detailed information about
establishing time factors.
SPEEDK n
Default: none. (The value NOT_SET is displayed)
Units: Kbps as integers, integers with K or M suffixes, or symbolic names
Range: 1 through 4,000,000,000 and symbolic values shown in table below
This modifier, introduced in G06.08 but not recommended as of G06.20, specifies the
line speed in Kbps.
Either RSIZE, SPEED, SPEEDK, LINETF, or PATHTF must be set, else the line
handler will display a configuration error.
You can specify SPEEDK values in Kbps or use symbolic names for line types that
have fixed speeds. The available names are listed in Table 17-2.
Here are the rules for converting SPEEDK to a time factor:
if SPEEDK >= FOX (21000) then the time factor = 1
For SPEEDK values less than FOX (21000) the time factor will be based on the
formula:
TF = Round( (4000000000 / SpeedK ) / 190000)
where the remainder is rounded up if it is .7 or larger.
This calculation will give a time factor of 1 for all lines which have a SPEEDK of FOX or
faster. If old profiles are used, a ServerNet line, ATM line, and a FOX line would all
have the same time factor of 1. This calculation will also limit the maximum time factor
to 186.
Starting with G06.20, you can use the new parameters, LINETF n and PATHTF n, to
set time factors for lines that will override all other parameters in calculating time
factors. PATHTF overrides RSIZE, SPEED, SPEEDK, or LINETF, whereas LINETF
overrides RSIZE, SPEED, and SPEEDK (but not PATHTF). Refer to Setting Time
Factors on page 18-23 for more detailed information on establishing time factors.
Table 17-2 shows the time-factor conversions for various SPEEDK settings:
