1 General

1.1 Purpose

The purpose of this document is to describe the Product Package for the High Density BSC & BSC/TRC ETSI/ANSI within GSM for 07B and later SW releases. This Product Package Description (PPD) covers: New Nodes Expansions Reuse of GDM hardware

This document also provides the following details: Estimated Capacity, Functionality, Allocation drawings, Floorplan and the estimated Maximum power consumption and number of fuses of the included cabinets.

1.2 Changes since last release of this document Chapter 1.4, 2.1.1 and 2.1.2, number of fuses reduced and fuse size updated. Chapter 1.4 and 1.6.4, SLI option added. Chapter 1.5.9, text about AGW and PGW ordering added. Chapter 1.5.7, Re-use subrack option added. DLEB and GESB option

included in this one.

1.3 Commercial Product Numbers

Commercial Product Numbers are the priced items in the commercial sales tools that correspond to the defined Base Configurations and the Optional Functionalities.

Commercial Product Numbers does, as opposed to Discrete Orderable Product Numbers, not contain the deliverable items and should not be used for ordering.

1.5.9 AGW/PGW improvement

AGW and PGW have a limitation in the ordering model due to MUP consumption. A total of 8 per subrack of any combination of AGW and PGW is possible. This makes it sometimes hard to order needed quantity since the ordering model requires that the last subrack is filled up with boards before the next subrack is allocated. We now introduce an option called ‘Reserved pos’ to increase the quantities to be available for AGW and PGW. ‘Reserved pos’ is a work around that allows a subrack to be filled up with ‘Dummy boards’ and a new subrack to be allocated. If you for example only have the option to add 12 PGW and you want 16 you should look in the option ‘Reserved pos’ and select 8 and you will find that for PGW you now have the possibility to order up to 20 boards.

The downside is that FAP 130 0516 doesn’t allow for the dummy boards selected with option ‘Reserved pos’ to be substituted for any other board in the future. Once a slot have been occupied with a dummy board selected with option ‘Reserved pos’ this allocation have to be remembered and the quantity have to be added for the option ‘Present number of Reserved pos’ in future expansions. The Dummy board generated with the question ‘Reserved pos’ is the same as the other Dummy boards in the node so it is not possible to find out number of ‘Reserved pos’ selected by calculating Dummy boards in a node.

The number of ‘Reserved pos’ selected have to be tracked by the ordering office. The information will be available in document "193 26-IPB number" for the node. In reality this will be a short term extra work. AGW orders will be more common than PGW and when AGW is implemented the TRA functionality is removed from the BSC/TRC and the node transform to a remote BSC. The CSPB 2.0 boards can now be removed and replaced with any other boards. When this happens FAP 130 0516 can no longer be used for expansion of the node and the ordering office should use the pick list in FAP 130 2171 for all future orders.

1.5.12 Site Products

Site products contain equipment related to the installation of the node. Site products is divided in Node Related Site Products (NRSP), see Appendix A, and Site Related Site Products (SRSP), see Appendix B.



12 (21)

1.5.13 Network Synchronization

The BSC can be provided with Network Synchronization (NS) references in a number of ways:

If the Reference Timing for NS is taken from an SDH network then Synchronization can be provided via the ET155 hardware

If the Reference Timing for NS is taken from a PDH network terminated in ETC devices then Synchronization can be provided via the CSM (or ET4-1).

If a Primary Reference Clock (PRC) like a Central Building Clock (CBC) exists at the switch facility, then Reference Timing for NS can be taken from there (ordered as SRSP).

If CSM (or ET4-1) is used to adapt the node to a PDH network environment, Reference Timing for NS over PDH can be distributed via CSM (or ET4-1) in the outgoing and incoming direction from the node.

The Network Synchronization planning shall recommend the best solution for the node, considering all the network implications and dependencies.

note: ET4-1 is an old product replaced by CSM.

1.5.14 Customer Product Information

All necessary supporting documentation can be found in the CPI Store. The documents can be downloaded or ordered on CD-ROM.

1.5.15 Optional Spares

To support the node, spare part management (available in HW Support service from Ericsson’s Global Services portfolio) is recommended. Alternatively, Spare Part Sale of single items is available. Please contact local Ericsson personnel for more information.

1.6 Expansions

All options are also available as expansions. Maximum capacity of all option packs is not possible. The group switch is the limiting factor and allows for 8 eGEM subracks to be used for base configuration and option packs. The eGEM with APZ 212 55 and APG43/2 is not included in this number.

Please refer to respective see Product Package Description/Ordering Guide for further details: Products Description Product Package

221 03-FAP 130 0258

2135-FAP 130 896 Power Supply

Power systems are available for high-ohmic distribution (HOD) and low-ohmic distribution (LOD):

ACTURA 48701 HOD/LOD max 86kW, Emerson ACTURA FLEX 48300 HOD max 30kW, Emerson Compact/Modular HOD/LOD max 40 kW, Power One 2135-FAP 130 0178

Power Distribution

The Enclosed Power Distribution Unit (EPDU) is a system for conversion of LOD to HOD for –48V DC power. Intended for use where a power plant with LOD provides DC power to HOD equipment, such as AXE.

221 03-FAP 130 824

Inverters Inverters are available in Small, Medium and Large configurations.

221 03-FAP 130 0259

AXE Operation and Maintenance (O&M)

AXE O&M equipment includes products from IO to terminal end equipment, for example LAN kit, extra alarm displays, inverter kit, WinFIOL and tools licenses.

221 03-2/FAB 102 616

IP RAN

Ericsson’s complete e2e IP RAN consists of the following product and solution components: -GSM, WCDMA, LTE IP RAN, -Mobile backhaul (MBH), -IP RAN Reference solution, -Site Integration Unit (SIU), -OSS

Mobile PBN

The Mobile PBN design describes inter-site backbone connectivity and intra-site connectivity design for all Core Network CS and PS nodes, MSC’s, GSN’s, MGw's, etc. M-PBN also includes the connectivity of these nodes to internal and external networks.

Distribution Frames The Distribution Frames (DF) package consists of Digital DF (DDF), Optical DF (ODF), Flexfield and Main DF (MDF).

221 03-2/FAB 102 615

Raised Floor Raised floor is generally recommended by Ericsson and must be used when under floor cabling is chosen.

External Mechanics External mechanics are used for cabling between the node and other site elements.

Earthquake Reinforcements

Earthquake reinforcement contains earthquake frames with mounting set for raised floor or for concrete floor.

221 03-2/FAB 102 667

Network Synchronization

(GPS Clock)

The GPS Synchronization Clock works as a primary reference clock and provides Network Synchronization and Time of Day. The GPS Synchronization Clock product is housed in a BYB 501 cabinet and includes a GPS antenna.

221 03-2/FAB 102 792

DataCom cabinet The DataCom cabinet (double deep BYB 501) is adjusted to have more space for DataCom equipment that requires side-to-side airflow.

221 03-FAP 130 710
