10.2 Circuit Properties
to the Cisco ONS 15454 DWDM Installation and Operations Guide for more information.
Low-order VCAT circuits are VC3. For information on the number of supported members for each
card, see Table 10-12.
• OCHNC Wlen—For OCHNCs, the wavelength provisioned for the DWDM optical channel network
connection. (DWDM only; refer to the Cisco ONS 15454 DWDM Installation and Operations Guide
for more information).
• Direction—The circuit direction, either two-way (bidirectional) or one-way.
• OCHNC Dir—For OCHNCs, the direction of the DWDM optical channel network connection,
either east to west or west to east. (DWDM only; refer to the Cisco ONS 15454 DWDM Installation
and Operations Guide for more information).
• Protection—The type of circuit protection. See the “10.2.3 Circuit Protection Types” section on
page 10-7.
• Status—The circuit status. See the “10.2.1 Circuit Status” section on page 10-4.
• Source—The circuit source in the format: node/slot/port “port name” virtual container/tributary
unit group/tributary unit group/virtual container. (The port name appears in quotes.) Node and slot
always display; port “port name”/virtual container/tributary unit group/tributary unit group/virtual
container might display, depending on the source card, circuit type, and whether a name is assigned
to the port. If the circuit size is a concatenated size (VC4-2c, VC4-4c, VC4-8c, etc.), VCs used in
the circuit are indicated by an ellipsis, for example, VC4-7..9 (VCs 7, 8, and 9) or VC4-10..12 (VC
10, 11, and 12).
• Destination—The circuit destination in same format (node/slot/port “port name”/virtual
container/tributary unit group/tributary unit group/virtual container) as the circuit source.
• # of VLANS—The number of VLANS used by an Ethernet circuit with end points on E-Series
Ethernet cards in single-card or multicard mode.
• # of Spans—The number of inter-node links that constitute the circuit. Right-clicking the column
displays a shortcut menu from which you can choose to show or hide circuit span detail.
• State—The circuit state. See the “10.2.2 Circuit States” section on page 10-5.
