Prerequisites

The prerequisites for the installation of HP OpenCall SS7 3.1 on Linux are as follows:

Skills

To perform the installation, you need a good knowledge of the following areas:

Linux: During the configuration of the HP OpenCall SS7 platform, some Linux system files are modified and several commands are used for configuration and customization.
HP OpenCall SS7 administration.

Documents

During the installation of HP OpenCall SS7, you should have the following documents at hand:

Linux Installation Manuals
HP OpenCall SS7 3.1 on Linux Documentation Set
HP OpenCall SS7 3.1 on Linux Release Notes
License codeword for HP OpenCall SS7 3.1 on Linux

Hardware

Installation of the host servers of your platform must be complete before starting any of the software installation procedures.




	NOTE: It is not necessary to have installed the SS7 hardware (TSU/TSC) before starting this software installation. This is done later.

Memory Requirements

The minimum physical memory required is:

256 MB additional memory for a single Local Point Code (LPC) platform
256 MB additional memory needed for each extra LPC

The virtual memory (VM) required by LPC depends on the number of Destination Point Codes (DPCs) configured on the network:

24 MB for 50 DPCs:
- 50 DPCs, 100 routes
- 50 DPCs (Remote SP), 100 Sub-System Numbers (SSNs)
- 500 Global Title (GT) entries
27 MB for 200 DPCs:
- 200 DPCs, 400 routes
- 200 DPCs (Remote SP), 400 SSNs
- 2048 GT entries
33 MB for 512 DPCs:
- 512 DPCs, 1024 routes
- 512 DPCs (Remote SP), 1024 SSNs
- 2048 GT entries
52 MB for 1024 DPCs:
- 1024 DPC, 4096 routes
- 1024 DPC (Remote SP), 4096 SSNs
- 4096 GT entries

ISUP and TUP requirements

The requirements for TUP and ISUP in non distribution mode are as follows:

For each LPC configured with CIC-based distribution: 65 MB
For each application 15 + (Number of configured CICs/1000) MB
The requirements for ISUP configured in CIC-based distribution mode are calculated as follows:
100 MB for 1024 DPCs:
1024 DPC, 100,000 circuits configured

Example of the calculation for a single LPC platform hosting 20 primary applications, 20 secondary applications with the maximum number of configured CICs (100, 000)

65 + 40 x 15 + 100 = 765 MB

Software

To install the software, you need the following CDs:

Linux operating system (appropriate distribution)
HP Opencall Enablement Kit
HP OpenCall SS7 3.1 on Linux software
