6.1 Service Support Capability of Ethernet Boards
Ethernet boards are classified into Ethernet transparent transmission boards and Ethernet
switching boards, based on the type of the accessed service. The Ethernet transparent
transmission boards support only EPL services, whereas the Ethernet switching boards support
EPL services, EVPL services, and Layer 2 switching function.

6.2 Requirements for Binding Paths with VCTRUNKs on
Ethernet Boards
One VCTRUNK on an Ethernet board can only be bound with timeslots of the same level.

Requirement for Binding Paths with a VCTRUNK
EGT1
l
The VCTRUNKs can be bound with the VC-12 VC-3 and VC-4 paths.
l
Only one VCTRUNK with a maximum bandwidth of 1.25 Gbit/s is supported.
l
VCTRUNK1 can only be bound with the fourth VC-4, namely, VC4-4, if the path binding
is at VC-12 level.
l
VCTRUNK1 can be bound with the first to eighth VC-4s, namely, VC4-1 to VC4-8, if the
path binding is at VC-3 level.
EFS8
l
The VCTRUNKs can be bound with the VC-12 paths and VC-3 paths.
l
Eight VCTRUNKs are supported. The maximum bandwidth of each VCTRUNK is 100
Mbit/s.
l
VCTRUNK1 to VCTRUNK8 can only be bound with the fourth VC-4, namely, VC4-4, if
the path binding is at VC-12 level.
l
VCTRUNK1 to VCTRUNK8 can be bound with the first to fourth VC-4s, namely, VC4-1
to VC4-4, if the path binding is at VC-3 level.
