IP Audio Routing & Mixing System
SECONDARY CORE - ROUTER INTERFACES - SUGGESTED SETTINGS
The suggested default settings for the Secondary Impulse Core Router Interfaces are shown below. Use the tables
below to configure your AoIP Router ports and to record the serial number and label details of each router port for later
reference. After configuring the AoIP Router interfaces, you may want to attach labels to them. A blank label sheet is
provided with the Impulse core for this purpose. A printer template for this Label sheet is available to distributors on the
Calrec Website.
