Preface
In Edition 01 Sections Connect BTS (Section 2.3.5) and Disconnect BTS(s) (Section 2.4.2) were updated following system evolution changes. Overall document quality was improved following an editorial review. Improvements were made in the following sections due to system evolution: Prerequisites (Section 1.2.1) Check Working PRC ( Section 2.3.4.3 ) Connect BTS (Section 2.3.5) Start Traffic on Added BTS (Section 2.3.6). The following sections were updated due to system evolution: Create Abis (Section 2.3.2) Create BTS(s) (Section 2.3.3) Delete Abis (Section 2.4.7) Delete BTS (Section 2.4.6). The note regarding settings made in the Remote Settings panel was removed from Create BTS(s) (Section 2.3.3). First official release of the document for B10.

1 Overview
1.1 Presentation The logical configuration can be activated completely independently from the physical connection of the BTS. Creating adjacencies and call tests must be done after the BTS is functional and connected to the network. Co-ordination is needed between the BTS and OMC-R sites to define the initial settings. The Qmux address must always be set. For 9100/9110 Micro BTSs, the transmission mode is configured via OML. G2 BTSs are supported by 9130 BSC Evolution only if they have a DRFU board. G1 MKII BTSs and G2 BTSs are supported by 9120 BSC only if they have a DRFU board. In order to create the required configuration, it is possible to add more than one new BTS and more than one cell. In this case, modify all the logical parameters at the same time in the same PRC. Manual Transmission Programming is recommended for multiple Abis operations on 9120 BSC. According to engineering rules: It is not allowed to have a cross-connect on the secondary Abis It is not allowed to attach a secondary Abis to a BTS that is in an Abis ring It is not allowed to use a mixed configuration for the primary and secondary Abis (terrestrial/satellite).
1.1.1 Cases The following cases apply: C1: BTS is installed on a new Abis link C2: BTS is installed on an existing Abis link with downstream BTSs C3: BTS is installed at the end of a non empty Abis chain (no downstream BTSs) C4: BTS has two Abis links.
1.1.2 Options The method takes into account the following options: O1: Configuring GPRS for the cells O2: Abis connection via satellite O3: Create cell(s) shared (applicable only to 9100 BTSs) O4: Define BTS Extra Abis Timeslots O5: Manual Transmission Programming O6: Automatic Transmission Programming.

1 Overview
1.2 Preparation 1.2.1 Prerequisites The following prerequisites apply: BTS sites are clean, tidy, and easily reachable The primary or/and secondary Abis links are installed and qualified The BTS(s) is installed and commissioned For C2, the jumper linking the upstream and downstream BTSs is installed. This jumper is removed during the scenario. For C4: The added BTS must be an 9100 BTS equipped with a SUMA board or an 9110-E Micro BTS equipped with a MSUMA board If the primary Abis link is on satellite, the secondary Abis link must also be on satellite The added BTS must be alone on a primary Abis, in the end of chain position The added BTS must not have any G3 TRE or 9110 Micro BTS on second Abis The BTS must not contain any G3 TREs for a configuration with more than 12 TREs. For O3, clock synchronization cable(s) must already be installed between BTSs involved in shared cells For O3, in a cell shared over two BTSs, only one sector (main or secondary) must support GPRS traffic (not both) BTS(s) must be configured with the correct initial settings There are adequate resources to handle the new traffic channels and LAPD All BTS software packages and OMU-CPF are loaded in the BSC memory.

1 Overview
1.2.2 Site Specific Information You must have the following specific information to complete the scenario: Identity of cases and options to perform BTS site topology For C1: the characteristics of the Abis (name, Qmux timeslot if BTS(s) to add is G1/G2 BTS) For C4: the name of the primary and secondary Abis link, MAX_EXTRA_TS_PRIMARY Characteristics of the BTS(s) (family, hardware generation, name, Qmux address, number of sectors, type of transmission, antenna diversity, master or slave, Qmux timeslot for G1/G2 BTS) List of cells to create with parameter values (LAC, CI, frequency, timeslot definition). The list must be exhaustive. List of cells supporting GPRS and parameter values (Routing Area Code for GPRS, Routing Area Color for GPRS, Min_Pdch, Max_Pdch_High_Load, Max_Pdch, EN_EGPRS, Max_GPRS_CS, PS_PREF_BCCH_TRX, TRX_Pref_Mark, MAX_ENGPRS_MCS) List of adjacencies with parameters (list of impacted cells, direction of the handover).
1.2.3 External Tasks You must take the following external tasks into account: All cells are declared at the MSC site The MSC personnel must perform an MSC database update to take into account the parameters for the new BTS For O2, check and update, if needed, the CRC4 for the Abis at the BSC site Update adjacencies on neighboring OMC-Rs, if necessary.
