Context
For the principle and configuration of trTCM by CoS remarking, see Configuring PW-based
trTCM by CoS Remarking.
The following ATM service types are available:
Issue 01 (2014-04-30)
shows an example network of the ATM PWE3.
Users access to MA5600T/MA5603T/MA5608T using xDSL service boards.
The PW encapsulation mode is used to enable the transparent transmission of data over the
IP network.
PWs in the Ntol mode are used. Specifically, one PW is bound to multiple PVCs so that
the same service from multiple users is carried by the same PW.
In the upstream direction, the trTCM by CoS remarking based on PWs is used; in the
downstream direction, the early drop based on CoS threshold is used. In this way, QoS can
be guaranteed for various services.
The xDSL board and the SPUB board must be in position and must work in the normal
state.
The static routing protocol or the OSPF protocol must be successfully configured on each
device in the network (the host route of each port must be successfully advertised).
