DCC Tunnels, Port Naming | Cisco Systems ONS 15327 manual

New Features and Functionality

DCC Tunnels

SONET provides four data communications channels (DCCs) for network element operations, administration, maintenance, and provisioning: one on the SONET Section layer and three on the SONET Line layer. With Release 3.3 the ONS 15327 uses the Section DCC (SDCC) for ONS 15327 management and provisioning. You can use the Line DCCs (LDCCs) and the SDCC (when the SDCC is not used for ONS 15327 DCC terminations) to tunnel third-party SONET equipment across ONS 15327 networks.

A DCC tunnel is a series of connection points that map third-party equipment SDCCs to ONS 15327 LDCCs. DCC tunnel end-points are defined by Slot, Port, and DCC type, where DCC can be either the SDCC, Tunnel 1, Tunnel 2, or Tunnel 3 (LDCCs). You can link an SDCC to an LDCC (Tunnel 1, Tunnel 2, or Tunnel 3), and an LDCC to an SDCC. You can also link LDCCs to LDCCs and link SDCCs to SDCCs.

The ONS 15327 OC-3 card supports tunnels on all four ports. Each ONS 15327 and 15454 can support up to 32 DCC tunnels. The maximum number of optical ports available on a 15327 is 16 (four-port OC-3 cards installed in all high-speed slots). Each port can support four different DCC tunnels (one section and three line). This allows 64 (4 x 16) tunnel terminations. Because each tunnel must have two terminations, the ONS 15327 can support a maximum of 32 DCC tunnel connections.

For details on DCC tunnels you can create on the ONS 15327 and instructions on how to create them, consult the Cisco ONS 15327 User Documentation, Release 3.3.

Port Naming

Release 3.3 provides the ability to store a name with each ONS 15327 traffic card port. Right-click the port to view the name. Other port naming features include:

•Node and network alarm and history panels: when an alarm affects a named port, or a circuit that traverses a named port, the port name is displayed in the alarm.

•Circuit creation: if a port is named, CTC displays the port name and port number.

•Node and network circuit list: if either or both circuit end points are named, CTC displays the port name and port number.

•Node provisioning: if any port is named, CTC displays the port name and the port number (panes affected include line and threshold).

•Node maintenance: if any port is named, CTC displays the port name and the port number (loopback).

•Node performance data: if any port is named, CTC displays the port name and port number.

Search for Circuit by Name

Release 3.3 allows you to search for circuits by circuit name, or by a substring included in the circuit name. The substring search allows you to jump down an alphabetically sorted list of circuits to those beginning with a particular letter. Enter the circuit name (or a substring included in the name) in the Circuit Name Search dialog box and click “Find Next.” You can search up or down the list of circuits. The search tool selects the circuit bearing the name you type. Once you have found the circuit, you can open it by double-clicking the selected row.
