Functions

• Provides 10M/100M Ethernet electrical interfaces and 100M optical interfaces, whose electrical characteristics, such as the flow control function, comply with IEEE 802.3x.

• Supports the working modes of auto-negotiation, 100M full-duplex/half-duplex and 10M full-duplex/half-duplex.

• Supports the ML-PPP encapsulation protocol with the encapsulation granularity of VC-12.

• Provides bandwidth sharing and statistical multiplexing based on virtual local area network (VLAN) and port to improve the bandwidth utilization.

• Supports Ethernet layer 2 switching.

• Supports isolation among different users, and VLAN isolation within one user.

• The ET1 and ET1D boards support Ethernet private line (EPL) services. The ET1O, ET1D, and EF1 boards support Ethernet private LAN (EPLAN) services.

• Supports multicast and broadcast.

• Supports the Rapid Spanning Tree Protocol (RSTP) to prevent broadcast storms.

Table 1 lists the functions of the ET1, ET1O, ET1D, and EF1 boards.

Application

The ET1, ET1O, ET1D, and EF1 boards are interconnected with PCs, routers or Ethernet switches to transmit Ethernet services. Pay attention to the following points:

• The ET1 and ET1D boards support transparent transmission of services and are applicable to EPL services.

• The ET1O, ET1D, and EF1 boards support layer 2 switching of services and are applicable to EPLAN services.

• The EF1 board provides 100M optical interfaces and can be interconnected with the data equipment that provides 100M optical interfaces.

• The ET1, ET1O, ET1D, and EF1 boards use the same encapsulation protocol and mapping granularity. Hence, they can be interconnected with each other.
