Circuit Type
|
Defines the circuit type:
STS: Creates a specific synchronous transport signal (STS) circuit.
VT: Creates a virtual tributary (VT1.5) circuit. (ONS 15600 nodes do not support
VT circuits.)
VT Tunnel: Creates a VT tunnel. VT tunnels allow VT1.5 circuits to pass through
an ONS node without using cross-connect card resources. VT circuits using VT
tunnels use cross-connect capacity only at the source and destination nodes.
(ONS 15600 nodes cannot be the source or destination node for VT Tunnel
circuits.)
VT Aggregation Point: Creates a VT aggregation point (VAP). VAPs allow VT
circuits to be aggregated into an STS for hand off to non-ONS networks or
equipment, such as interoffice facilities (IOFs), switches, or a digital access
cross-connect system (DACS). VAPs reduce VT matrix resource utilization at the
node where the VT1.5s are aggregated onto the STS. This node is called the STS
grooming end. The STS grooming end requires an OC-N, EC-1, or DS3XM card.
VT aggregation points can be created on a bidirectional line switched ring
(BLSR), 1+1, or unprotected nodes, but cannot be created on unidirectional path
switched ring (UPSR) nodes.
STS-V: (ONS 15310-CL and ONS 15454 only) Creates a virtual concatenated
(VCAT) STS circuit.
VT-V: (ONS 15310-CL and ONS 15454 only) Creates a virtual concatenated VT
circuit.
OCHNC: (ONS 15454 only) Creates an optical channel network connection
(OCHNC) between ONS nodes that are provisioned for dense wavelength
division multiplexing (DWDM).

Num. of Circuits
|
Sets the number of circuits to be created (STS, VT, and VT tunnel circuits only).
|
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.
