Platforms in CS core network

Platforms in Nokia CS core network :

1. DX 200

DX 200 is a platform used, for example, in the MSC, MSS, GCS, CDS, HLR and SRRi network elements. The DX 200 provides high capacity in small footprints. The capacity of a DX 200 platform is determined by its static and dynamic capacity. The static capacity (memory) is the ability of the equipment to store all relevant data for its operation whereas the dynamic capacity refers to the ability to process transactions (for example, calls and handovers). The capacity can easily be accommodated to the operator's needs.

The hardware of a DX 200 platform can be based on either subrack or i-series construction, although the i-series hardware exchange requires less space for installation. Only elements using the i-series cartridge mechanics can be updated to meet the requirements of future releases. Elements based on the subrack hardware can continue to serve GSM traffic.

The elements in a DX 200 platform are built of plug-in units (PIUs) and cartridges. These are installed in racks or cabinets to suit the customer-specific configuration needs. The system is easily expandable by adding PIUs.

Configuration commands are used to manage the software. With these commands, the user can install a new software package in the network element, test the new software before taking it into use, update an existing package, and back up the software. The built-in redundancy of the system architecture also helps to ensure that software updating is seamless.

2. IPA 2800

IPA 2800 is a gateway platform for various switching and gateway applications between circuit switched (PSTN) and packet switched (IP, ATM) environments, where the emphasis is on effective user plane manipulation. The IPA 2800 hardware is based largely on the use of commercially available technology. Only a limited number of generic purpose plug-in units is used to build up the various network element configurations.

The IPA 2800 is used in the Multimedia Gateway (MGW) and Radio Network Controller (RNC) network elements. The following attributes are valued in the architecture:

. support of standard open interfaces
. open architecture for 3rd party partnering
. carrier class reliability
. high scalability in terms of transaction capacity, the number and type of interfaces and a rich set of selectable features
. cost-efficiency and compact physical size
. competitive development environment with respect to time-to-market issues.
