Service Mapping
Gigabit • SDH mode:
Ethernet
— GFP-F to VC3, and VC4
L1
— GFP-F to VC3-nv (n=1 to 12) and
VC4-nv (n=1 to 4)
E1 • VC12/TU12/AU4 (SDH mode)
DS1 • VC11/TU11/AU4 (SDH mode)
E3/DS3 • VC3/TU3/AU4 (SDH mode)
10/100BT Ethernet, Gigabit Ethernet and PDH services are mapped to SDH
containers and assigned as SDH level connections to STM-1/4 interfaces. The
traffic protection schemes supported by the STM-1/4 interfaces can therefore
be used to provide a protected Ethernet, E1/DS1 or E3/DS3 service without the
requirement of a redundant handoff from the subtending 10/100BT Ethernet,
Gigabit Ethernet, E1/DS1 or E3/DS3 equipment. See

Hair-pinning

The OME6130 provides the ability to provision hairpin connections for PDH
services.

Connection management application

OME6130 connection management is based on a nodal, port-to-port
connection management philosophy that takes protection schemes into
account to rearrange connections at the physical level to implement traffic
protection. See
The Cross-connect application in the local craft access terminal allows the
user to perform the following:

filter, and display nodal connections
provision nodal connections from any E1/E3/DS1/DS3 interface port to
any available timeslot of an STM-1/4 interface or of another
E1/E3/DS1/DS3 interface port on the same OME6130 network element.
Each cross-connect can have a Circuit Identifier which allows the user to
label the cross-connect.

Interconnection type
• SDH mode:
— non-concatenated at VC3, and VC4 level
— virtual concatenation at VC3-nv (n=1 to 12) and
VC4-nv (n=1 to 4) for the VCG
• non-concatenated at VC12 level
• non-concatenated at VC11 level
• non-concatenated at VC3 level
