When a DAS is connected to two concentrator ports, it is called dual-homing. One port is the active link, where data is transmitted and the other port is a hot standby. The hot standby link is constantly tested and will kick in if the active link fails or is disconnected. The B-port in a DAS is usually the active port and the A-port the hot-standby.
