Tab. 79 Connections on the Aastra DECT radio units
If an SB-8 / SB-8ANT is operated on two DSI interfaces, it is recommended always to
use two neighbouring ports.
Aastra Intelligent Net:
As the DECT systems of the individual nodes in an AIN do not run syn-
chronously, the two DSI interfaces of an SB-8 / SB-8ANT must always be
connected to the same node.
