Compendium: OM SIP – DECT Solution Large SIP-DECT System

Large SIP-DECT System

This chapter describes how to set up a SIP-DECT 4.0 system with a very large

number of RFPs (up to 2,048). This includes configuration of up to two OMMs

running on a Linux PC server system, dynamic IP configuration of RFPs via DHCP,

and a multi DECT cluster system deployed to several separate buildings.

Prerequisites

You need two Linux PC server systems, a larger number of RFP devices as well as a

number of DECT handsets – preferably Aastra 6x0d, Aastra 6x2d or Aastra 650c.

You should have obtained a license file from the Aastra license server.

>OM System Manual:

802.1Q Support

Your company LAN should allow connections from the mounted RFPs to your SIP

PABX, preferably a switched network with a separate VLAN for SIP/VoIP.

Install OMM on a Linux PC server system

>OM System Manual:

Installing OMM in Host

Mode

Install the OMM software on up to two dedicated i386 32-bit PC server systems

running Red Hat Enterprise Linux 6. While it is possible to operate the OMM

software on various PC systems, only the recommended hardware/software con-

figuration is tested by Aastra and may only receive full support for this reason.

Tip: A brief explanation on how to set up ”Red Hat Enterprise Linux Server 6“

can also be found in the “OM Locating Application” guide in the “Installing

Red Hat Enterprise Linux Server 6” chapter. Do not install additional web

server software to prevent blocking port 80 and port 443 that are required

by the OMM software.

Please note: Choosing the right hardware, setting up and managing multiple

Linux server systems, and integrating Linux servers in your company LAN/

VLAN environment is beyond the scope of this compendium. You should

at least read the “Red Hat Enterprise Linux 6 – Installation Guide” that is

available on the Internet under http://docs.redhat.com/does/ URL.

>OM System Manual:

OMM Standby

One Linux server runs the primary OMM while a second Linux server takes over the

OMM function in case of failure. On the main and optionally the backup Linux

server, install the OMM software with the following basic steps.
