Use Reference Table 2 on page 114 to determine the quantity of trunks
required to meet the trunk CCS at cutover, two-year, and five-year intervals.
In this case:
•
17 DID trunks are required at cutover
•
18 DID trunks are required in two years
•
21 DID trunk are required in five years
For trunk traffic greater than 4427 CCS, allow 29.5 CCS/T.
Once the quantity of trunks required has been estimated, enter the quantities
in Worksheet A for cutover, two-year, and five-year intervals. 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/T. This value is
also entered in "Worksheet A: Growth forecast" on page 135.
Line load is calculated by multiplying the total number of 500-telephone TNs
by the line CCS/T. The number of TNs is determined as follows:
•
one TN for every DN assigned to one or more Analog (500/2500 type)
telephone
•
one TN for every Meridian Digital Telephone without data option
•
two TNs for every Meridian Digital Telephone with data option
Trunk load is calculated by multiplying the total number of digital telephone
and 500-line TNs which have access to the trunk route by the CCS/T per trunk
route.
Console load is calculated by multiplying the number of consoles by 30 CCS
per console.
