Example 2:
Parameter assignment of a 2 ended leased line constellation with 2 connections (FOS0–
Configurators).
Figure 35 Parameter assignment for 2 ended, leased line configuration
In opposite to a dialing line the parameter assignment of a leased line is easier. All numbers
are assigned by the communication switch so there is no need to assign any number for the
CC–S . Futhermore the choice of "DIAL" or "ACCEPT" is not necessary.

The communication link between the CC–S 's and the S –Bus is established by the
0 0
communication switch. As far as the CC–S 's are connected to the S –Bus the transmission
0 0
starts. In a leased line application any routing of the data is made by the communication
switch.
The routing from the D–channels to the fibre optic cables is also fixed. The B1–channel is
always routed to the FO1/LWL1 interface and the B2–channel is routed to FO2/LWL2
interface.
