42 Interworking requirements with CS 1000

You can use one of the two following methods to calculate the PSTN

trunks and SIP Access Ports:

• "Trunk calculation: Method 1" (page 42)

•

"Trunk calculation: Method 2" (page 43)

To calculate the number of UEXTs required, see "UEXT calculations"

(page 46).

For more information about CS 1000 capacity, see Communication Server

1000E Planning and Engineering (NN43041-220).

Trunk calculation: Method 1

Follow these steps:

1. Add the number of client users.

2. Locate the resulting number in the Number of Users column in Table 5

"Poisson trunk table" (page 42).

3. Select the appropriate PSTN and SIP Access Port parameters based

on the required CCS per Users.

Table 5 "Poisson trunk table" (page 42) uses a Poisson value of P.01,

which represents 1 percent blocking.
