Circuit Type
|
Defines the circuit type:
VC_HO_Path_Circuit: Creates a specific high-order path (VC4 or VC4
concatenated) circuit.
VC_LO_Path_Circuit: Creates a low-order path (VC3 or VC12) circuit.
VC_LO_Path_Tunnel: Creates a VC low-order path tunnel. VC low-order path
tunnels allow VC3 and VC12 circuits to pass through an ONS node without using
low-order cross-connect resources on the cross-connect cards. Low-order
circuits using tunnels use low-order cross-connect capacity only at the source
and destination nodes. One low-order tunnel can carry three VC3s, and each VC3
can contain a VC3 circuit span or 21 VC12 circuit spans.
VC_LO_Path_Aggregation: Creates a low-order aggregation point (LAP). LAPs
allow low-order VC12 and VC3 circuits to be aggregated into a VC4 for handoff
to non-ONS 15454 SDH networks or equipment, such as interoffice facilities
(IOFs), switches, or digital access cross-connect systems. The VC4 grooming
end of the LAP requires an STM-N card. LAPs can be created on MS-SPRings,
1+1, or unprotected nodes, but cannot be created on SNCP nodes.
VC_HO_Path_VCAT_Circuit: Creates a high-order path VCAT VC4 circuit.
VC4-V circuits require ML-Series and FC_MR-4 cards at the circuit source and
destination nodes.
VC_LO_Path_VCAT_Circuit: Creates a low-order path virtual concatenated VC
circuit. VC-V circuits require ML-Series and FC_MR-4 cards at the circuit
source and destination nodes.
OCHNC: Creates an OCHNC between ONS nodes that are provisioned for
DWDM.

Num. of Circuits
|
(High-order path and low-order path circuits only.) Sets the number of circuits to be created.
|
For VC3 Port Grouping Only
|
Displays only with the VC_LO_PATH TUNNEL circuit option. Check this box for VC3 port grouping.
|
Auto-ranged
|
Creates identical (same source and destination) sequential circuits automatically. The check box is automatically selected if you enter more than 1 in the Num. of circuits field. Unchecking the check box turns off autoranging.
