Guide To Create Cross-connection Huawei 52h46

Guide to create cross-connections This guide provides steps to create cross-connections in Optix RTN 950. The crossconnection could be a drop/insert type or -through type. Cross-connections between IF cards and between IF card and SL1D card are -through cross-connections. Any cross connection that uses SP3S card is a drop/insert cross-connection. Resources used to create cross-connections are as follows: Operating System: Windows 7 Professional PC/Laptop: Lenovo T410 Browser: Internet Explorer 8 Craft Terminal application: iManager U2000 Web LCT V100R006C00SPC200 Network Element: Optix RTN 950 running on 5.76.03.32. Cards used: 2 x ISU2, 1 x SP3S Cable: LAN cable (straight, RJ45)

A hypothetical site 3001 has been considered to illustrate the steps to create crossconnections. Suppose the chain containing site 3001 is as follows:

Suppose the Optix RTN 950 IDU at site 3001 has the following slot allocation: Slot 2: SP3S (provides interface to connect to 2G and 3G equipment) Slot 3: ISU2 (provides interface to upstream direction, i.e., towards site 2001) Slot 5: ISU2 (provides interface to downstream direction, i.e., towards site 4001)

Assume detailed design document for the site 3001 shows cross-connections as shown below. Board Slot 5-ISU2 Slot 5-ISU2 Slot 3-ISU2 Slot 5-ISU2 Slot 3-ISU2 Slot 5-ISU2

The list of cross-connections created above is displayed in the NE Explorer. Note that the third row in the cross-connection list is for two cross-connections created in steps 3 and 4 above.

Note: 1.

Creation of cross-connection fails if the time-slot is already used.

2.

Creation of cross-connection fails if the time-slot selected to create cross-connection is larger than guaranteed E1 capacity defined in the IF/ODU page. (See red box in the figure below)
