. Switching of transmission devices will affect the POS interface. When the POS interface is interconnected with the peer end through the transmission device, if the transmission device performs switching between the active and standby ends, the POS interface may be transient disconnected and an SDH alarm is triggered. If the active link is interrupted, the active link signal becomes invalid, and the POS interface detects that the transient channel si

The LAN switch supports a speed from 10 m to 10G. The transmission medium uses copper wires or optical fiber cables, and the port ranges from several to several hundred. This type of switch generally supports TCP/IP and UDP, IPX, and AppleTalk protocols. Other features of this type of switch include: support for VoIP (IP-based voice service), QoS (service quality evaluation), bandwidth management and automatic report generation, support for multicast

(The loop mentioned here is not a link between switches. Instead, the port of the switch is connected to the transport SDH device. The port of the transport SDH device has a self-ring. If the broadcast package enters the port, the packets wil
