Additional trunk lines
When the capacity of the ICS is increased, traffic from the new extensions may saturate the
existing trunk lines. To avoid this, you can install additional trunk lines.
Perform the following tasks to add a new trunk line:
• connect a trunk line
• declare the network junctor
Connecting a trunk line
Adding a new trunk line requires an unused circuit card. If necessary, install and connect a new
circuit card.
The table below gives details of the trunk line circuit cards.
