This example assumes that the network topology and microwave links have been configured.

Tail-end sites on the network transmit base station services by using point-to-point

transparently transmitted E-Line services.

"onfiguration Procedure

In this example, transparently transmitted E-Line services are configured for only one E

and therefore can only be configured on a per-E basis.

Networ*ing +iagramTail-end sites on the network transmit base station services by using point-to-point transparently

transmitted E-Line services.

!s shown in the following figure, E" is a terminal station of a backhaul network. The service

re#uirements are as follows$

E" must transparently transmit the Ethernet services from the ode% to E& in point-to-

point manner.

'()* flags must be used to identify the priorities of the Ethernet services from the ode%s.

To meet the preceding re#uirements, point-to-point transparently transmitted E-line services are

configured and a +o( policy is configured for the services.

Encapsulation type ull or point-to-point transparently

takes the fixed value of Null.

*ort working mode !uto-negotiation In this example, the /E port

on the ode% works in auto-negotiation mode. Therefore,

the peer /E port must alsowork in auto-negotiation

mode. If a peer Ethernet port

in the same mode.

The working modes of the

Ethernet ports within the

backhaul network are

uniformly planned as auto-negotiation.

Ethernet frames that carry more thanone tag such as +in+ can traverse the

e#uipment, the maximum framelength is set to "123 bytes. If the
