Functions and features supported by EFT8 boards Basic functions: Transparently transmits 8xFE or 16xFE services. Port types: ?Supports 10BASE-T/100BASE-TX signals. The electrical ports comply with IEEE 802.3u. ?Supports 10BASE-T/100BASE-TX signals when working with an ETF8 board. The electrical ports comply with IEEE 802.3u. ?Supports 100BASE-FX/100BASE-LX signals when working with an EFF8 board. The optical ports comply with IEEE 802.3u. Functions when being used with an interface board : Provides 16 electrical ports to receive/transmit Ethernet signals when working with an ETF8 board. Provides 8 optical ports and 8 electrical ports to receive/transmit Ethernet signals when working with an EFF8 board. MPLS technology : Not supported VLAN technology: Supports VLAN transparent transmission. Maximum uplink bandwidth: The maximum uplink bandwidth is 1.25 Gbit/s. An EFT8 board can adapt to the bandwidth of its slot. Maximum bound bandwidth: 24xVC-3, or 126xVC-12 + 18xVC-3 VCTRUNK specifications: Number of supported VCTRUNKs: 16 Configuration principles are as follows: ?Each VC channel can be bound only to one VCTRUNK. ?VCTRUNK1 to VCTRUNK8 must be bound when a board is housed in a slot providing 622M bit/s bandwidth. ?A VCTRUNK can be bound with the VC-12 path or VC-3 path at one time. A VCTRUNK should not be bound with VC-12 and VC-3 paths at the same time. ?A VCTRUNK can be bound with a maximum of three VC-3s or a maximum of 63 VC-12s. ?VCTRUNK 1-VCTRUNK 8 can be bound with VC-3s 1-12 or VC-12s 1-63. ?VCTRUNK 9-VCTRUNK 16 can be bound with VC-3s 13-24 or VC-12s 64-126. ?A VCTRUNK cannot be bound with VC-12s numbered 1-63 and VC-3s numbered 10-12 at the same time. In addition, a VCTRUNK cannot be bound with VC-12s numbered 64-126 and VC-3s numbered 22-24 at the same time. ?VC-4s numbered 4 and 8 support the binding of VC-3 and VC-12 paths. The other VC-4s support the binding of VC-3 paths only. ?In the case of the configuration of cross-connection, VC-12s numbered 1-63 should be configured into the fourth VC- 4, and VC-12s numbered 64-126 should be configured into the eighth VC-4.
