Huawei Technologies Co. It aims to ensure that the BSC can work properly by performing verification tasks related to equipment, BSC board software and data file loading, interfaces, and services. This document provides guidelines for commissioning the BSC Product Version The following table lists the product version related to this document. The software installation package, license, and MML command scripts required for commissioning must be ready.
Remote commissioning is performed by the remote engineer technical owner of the BSC and multiple BSCs can be commissioned simultaneously in the central equipment room. There is also another commissioning mode: remote commissioning through local assistance, which is performed by both the remote engineer and the site engineer.
The basic services consist of speech service and data service. Conventions Symbol Conventions The symbols that may be found in this document are defined as follows.

Requirements for Equipment Status Before commissioning, ensure that the equipment meets the conditions listed in Table Table Requirements for equipment status before commissioning Item Requirement BSC hardware The hardware is installed and passes the hardware installation inspection and power-on check. OMU Configured before delivery. Requirements for Commissioning the Network To ensure smooth verification of the Abis, Ater, A, and Gb interfaces, the network equipment in the commissioning network must meet the following requirements: l At least one BTS is connected to the local BSC The BTS should have passed the commissioning and can provide basic functions.
The CN equipment should have passed the commissioning and can provide basic functions. Figure shows a typical commissioning network. The quantity and type of cables are not specified. Other commissioning scenarios may be possible, as described in Table Figure shows the commissioning process.
Prerequisite The BSC cabinet has passed the power-on check. Procedure Step 1 Check whether the cabinet is powered on. The cabinet is not powered on, Go to step Step 2. The cabinet is powered on, Go to step Step 3. Step 2 Power on the cabinet by referring to Powering On the Cabinet. Step 3 Check the power supply to the cabinet components, as listed in Table Ensure that the hardware operates normally.
Context 5. In this mode, the site engineer plugs the USB drive for commissioning into the OMU to complete the installation of the operating system. The commission is performed through the collaboration between the remote engineer and site engineers. Select a verification method according to the actual scenario. Then, the OMU verification is performed through cooperation of the remote engineer. The information returned is running, 1.
Go to Step 6. The information returned is unused, Go to Step 6. The version of the OMU application is the Perform operations in Step 7 through Step same as that required by the operator, Then this task is complete.
The version of the OMU application is 1. Perform operations in Step 7 through Step Perform operations in Step 14 through Step NOTE To view the help information of the omutool, run the. Step 8 Change the external fixed IP address, subnet mask, and the gateway IP address according to the plan of the operator. Run the. For example, you can run the following command and then press Enter. In this case, the commissioning need not necessarily be performed in the BSC equipment room and can be performed in a centralized manner.
