Cooperate with ETS8 and TSB8 to realize 16-channel FE electrical signal TPS protection.
Interface Characteristics	Working Mode	FE electrical interface: supports self-negotiation, 100M full-duplex, 100M half-duplex, 10M full-duplex, 10M half-duplex. FE optical port: supports 100M full duplex.
	Port Flow Control Mode	Self-negotiation	Supported (not supported for FE optical port)
	Port Flow Control Mode	Non-self-negotiation	Support
	Port status query/configuration	Supported
	Interface type query	Support
	Optical Power Threshold Setting	Not supported
	Pluggable Optical Module	Not supported
Service Type	EPL	Supports PORT-based transparent transport.
	EVPL	Supports EVPL service with shared PORT. Supports EVPL service with shared VCTRUNK. VLAN tag isolation based MPLS label-based isolation Supports up to 4096 LINK services.
	EPLAN	Maximum support 2K blacklists and 2K static MAC addresses, 2K shared. Blacklist only supports destination MAC address checksum, not source MAC address checksum. Support source MAC address self-learning function, MAC address table size is 16k, support MAC address aging time setting and query. Supports static MAC routing configuration. Support dynamic MAC address query. The maximum number of VBs supported is 16, and the maximum number of logical ports per VB is 48. Supports querying the number of actual learned MAC addresses by VB+VLAN or VB+LP. Supports EPLAN service based on IEEE 802.1d MAC bridge.
	EVPLAN	Supports data isolation based on VB+VLAN method. The maximum number of VBs supported is 16, and the maximum number of logical ports per VB is 48. Supports the setting of up to 4096 VLAN services. Supports EVPLAN services based on IEEE 802.1q Virtual Bridge and IEEE 802.1ad Provider Bridge.
Service Specifications	Ethernet Data Frame Format	IEEE 802.3	Supports
		Ethernet II	Supported
		IEEE 802.1 q/p	Supported
	Frame Length Range	Support 1518Byte～9600Byte message length setting, support Jumbo frames up to 9600Byte.
	Mapping Method	VC-12, VC-3, VC-12-Xv (x≤63), VC-3-Xv (x≤12)

	Maximum Uplink Bandwidth	Maximum uplink bandwidth is 2.5Gbit/s, supporting slot bandwidth adaption.
	Maximum Bound Bandwidth	48xVC-3 or 252xVC-12+36xVC-3
	VCTRUNK Specifications	Quantity: 32 Configuration Features: After each level of VC channel is used by one VCTRUNK binding, other VCTRUNKs can no longer be used. When the slot bandwidth is 1.25G bit/s, VCTRUNK1 to VCTRUNK16 are required to be bound. The same VCTRUNK can only bind one level of channel, and cannot bind both VC-12 and VC-3 channels. The 4th, 8th, 12th, and 16th VC-4s can be bound to both VC-3 and VC-12 channels, while the other VC-4s can only be bound to VC-3 channels. Each VCTRUNK can bind up to 12 VC-3s or 63 VC-12s.
