Calculate line, trunk, and console load
Line, trunk, and console load
_
Once the quantity of trunks required has been estimated, enter the quantities
on Worksheet A (in Step 1) for the cutover, 2-year and 5-year interval. This
calculation must be performed for each trunk group to be equipped. The
total trunk CCS/T is the sum of each individual trunk group
CCS/r.
This
value is also entered on Worksheet A. (See Worksheet A at the end of this
document.)
Line
load
The line load is calculated by multiplying the total number of 500 and
SL-1 line Terminal Numbers (TN) by the line
CCS/r.
The number of TN is
determined as follows:
. .
-
one TN for every Directory Number (DN) assigned to one or more 500
or 2500~type set
-
one TN for every SL-1 set.
-
one Tn for every digital set M2xxx or M3xxx without data option.
-
two TNs for every M2xxx or M3xxx set with data option.
Trunk load
The trunk load is calculated by multiplying the total number of digital sets,
500, and SL-1 line TN having access to the trunk route by the
CCS/r
per
trunk route.
Console load
The console load is determined by multiplying the number of consoles by
30 CCS per console.
