Reference Procedures Performed At OMC–R Introduction The procedures in this chapter are referenced during various FRU replacement procedures and are performed by the OMC–R operator.
Accessing OMC–R CLI Window Accessing OMC–R CLI Window Many of the FRU procedures require the OMC–R operator to manipulate BTS logical devices. This is achieved via UNO or the OMC–R (Operations and Maintenance Center – Radio) Command Line Interface (CLI). The operator enters commands via UNO or OMC–R CLI. IMPORTANT * Should there be any issues which affect UNO or the OMC–R CLI operations, command dependent replacement procedures cannot be performed.
Circuit BTS Shut Down Procedures Shut Down Site Signaling Functions for a Circuit BTS If a complete site shutdown is required for the FRU replacement, follow the procedure in Table 10-2 to disable the circuit BTS site. CAUTION This site shut down procedure takes a BTS out–of–service (OOS), but does not affect other BTSs. To minimize system impact, it may be advisable (but not necessary) to perform this procedure during a maintenance window.
Circuit BTS Shut Down Procedures – continued Table 10-2: Shut Down Site Signaling Functions Procedure For a Circuit BTS n Step Action NOTE The REDIRECT command is used to redirect subscribers to an 800 MHz analog site or to invoke the REDIRECT2 command which is then used to redirect subscribers to a different CDMA carrier frequency. REDIRECT2 is the preferred command if an alternate CDMA carrier is available. * IMPORTANT Record the values shown in the following system display response.
Circuit BTS Shut Down Procedures – continued Table 10-2: Shut Down Site Signaling Functions Procedure For a Circuit BTS n Step Action NOTE This step edits the REDIRECT parameters so that the Global Service Redirect Message to be broadcast on the paging channel redirects all subscribers away from the BTS and onto a different BTS or system. 4 Enter the following command at the prompt: omc–000000>EDIT BTS– REDIRECT!
