Connection Management - Nortel Optical Multiservice Edge 6130 Planning Manual

Connection management

In the OME6130 architecture, traffic is switched between interface ports on the
circuit packs through the cross-connect matrix located on the 2x155/622M
aggregate circuit pack.
OME6130 supports the following connection management capabilities:
•
•
•
•
•
•
fully non-blocking cross-connects at VC11, VC12, VC3, and VC4
granularity
contiguous concatenated connections for VC4 rates
virtual concatenated connections for VC12-nv, where n = 1 to 63 or
VC3-nv, where n = 1 to 3 for the 10/100BT Ethernet ports
— the total bandwidth available for connections on the 8x10/100BT L1
circuit pack is STM-1 (155 Mb/s). The bandwidth is shared between
the 8 10/100BT ports of the circuit pack
virtual concatenated connections for VC3-nv, where n = 1 to 12 and
VC4-nv, where n = 1 to 4 for the Gigabit Ethernet ports
— the total bandwidth available for connections on the 2xGE L1 circuit
pack is 4 x STM-1 (622 Mb/s). The bandwidth is shared between the
two GE ports of the circuit pack
In OME6130 Release 1.0, the total bandwidth available for connections on
the NE is 16 x STM-1 (2.5 Gb/s) if the NE is commissioned with the node
capacity parameter set to STM-4 rate.
— half of the bandwidth (8 x STM-1 or 1.25 Gb/s) is dedicated to the two
STM-4 interfaces of the 2x155/622M aggregate circuit pack
— half of the bandwidth (8 x STM-1 or 1.25 Gb/s) is shared between the
four tributary circuit packs.
— the granularity of the bandwidth distribution among the tributary
circuit pack is STM-1. That is, the 8 x STM-1 are distributed to the
tributary circuit packs with a granularity of STM-1.
– For example, if slot 4 is using one STM-1, slot 5 is using four
STM-1 and slot 8 is using two STM-1, then the remaining
bandwidth available for slot 9 is limited to one STM-1
PDH/DSn signals mapping:
— E1 to VC12
— DS1 to VC11
— E3 to VC3
— DS3 to VC3
