THE NETWORK OFFERING
Nota : Alcatel OmniPCX Office supports analog ATLs from release
R1.5 onwards; please bear this restriction in mind when reading the "Private
Networks" section.
Global offering
Depending on the medium (or protocol) used, placing Alcatel OmniPCX Office systems on private
networks offers the following main services:
- calls on TLs and ATLs: conversion from private dialing for outgoing calls.
- calls on ISDN, QSIG_BC and VPN lines: CLIP/COLP services, conversion into private dialing for
outgoing and incoming calls.
- Public or Private ISVPN: in addition to the previous services, optimization of transfers and forwar-
ding, additional information (transmission of the name, busy status, forwarding).
- ISVPN+: with regard to ISVPN services, addition of metering information.
- IP Networking: setting up an IP network using the existing data network to carry voice data at lower
cost; for more details see the "Voice over IP" section.
The table below shows the principles of use for the various protocols, depending on the amount of
traffic and the requested level of service.
A private network can be homogenous or heterogeneous:
- homogenous: all the PABXs in the network belong to the same family (Alcatel OmniPCX Office,
Alcatel Office or Alcatel OmniPCX 4400).
- heterogeneous: the PABXs in the network belong to different families (Alcatel and others).
