| Repair and Maintenance Requests - Repair and Maintenance requests are initiated in three different
ways: 1) A subscriber reports an equipment or service problem 2) An error condition requiring service is detected at the EMS 3) A unit - BTS or SU - is scheduled for periodic maintenance, replacement or upgrade. Once a request is established through one of these three means, a Work Order is generated, resulting in technician response. Some maintenance actions may be addressed through the over-the-air download of AirLink 8000 1/30/00 BASE TRANSCEIVER STATION Release 1.00 2 - 19 software (patches or upgrades) to the SU. This will be accomplished over an assigned 64 kb/s channel with the software contained in the user data fields of the message frames. AirLink 8000 1/30/00 BASE TRANSCEIVER STATION Release 1.00 2 - 20 1.10 Provisioning and Configuration Provisioning and configuration activities involve initial provisioning of a new AirLink 8000 system and modifications to an existing system configuration. They are discussed briefly to familiarize the reader with some of the key provisioning concepts. A complete explanation of the provisioning process is covered in the AirLink 8000 Provisioning Manual. 1.10.1 Initial System Provisioning Initial system provisioning is the first ever deployment of the AirLink 8000 product into a given geographical service area and is in effect whenever a new DSCO is being deployed. All other provisioning activity (addition of BTSs or RBUs, CPE) will be considered modifications to the existing configuration. Once the architecture (number of RBUs, CPE, service mix, subscriber locations, etc.) for the system is determined and the BTS is physically installed and connected to the DSCO, the system installer (using the EMS interface) configures the Link Control Processor in the RBU to accommodate the particular scenario being provisioned. The LCP has the responsibility to coordinate and maintain all radio specific provisioning parameters. All AirLink 8000 systems are pre-configured for a generic installation. Site specific parameters are used to tailor this generic configuration to meet local requirements. Provisioning data is categorized as: -- Radio characteristics -- Service configuration - Telephony, Data service, payphone -- Hardware configuration -- Periodic functions -- DSCO/EMS configuration information -- Subscriber and CPE information Once the EMS, DSCO, and BTS components are successfully installed, the provisioning data entered for the CPE is used to create a Work Order to initiate the physical installation of the CPE by a technician (the overall procedures are not discussed here). The Initial Boresight Alignment Tool (IBAT) is the key craft accessory used in the provisioning the CPE/SU. The IBAT is a hand held, battery powered device that provides two essential functions in the installation of the Subscriber Unit: -- Transfers technician ID/Work Order Number information to the RBU to verify the authorized installation of the SU (provides SU and service theft protection). -- Assists the technician in aligning the SU antenna in a direction that maximizes RF link performance with the RBU. The IBAT reads the received power levels for various adjustment positions attempted by the installer. It stores the various signal levels and, after a series of readings, indicates to the installer when he has returned to the position of maximum link margin. |
