NATIVE VOIP
Alcatel OmniPCX Office
• Level 3 tagging and prioritization
available with Windows 98, 2000,
Millennium, NT4, XP
• handsets or headsets are available for
increased comfort.
H323 Devices
The OmniPCX Office supports standard
H323 (V1 & V2) devices such as PCs with
Microsoft NetMeeting.
IP Trunking
The Alcatel OmniPCX Office offers IP
trunking for up to 96 IP trunks. IP trunking
is available with 2 main types of access
to the WAN.
WAN Access through
the Alcatel OmniPCX Office
VoIP benefits from the OmniPCX WAN
QOS mechanism.
• Policing: Based on TOS/Diffserv
header, the OmniPCX Office puts Voice-
over IP in its high priority queue.
• Queuing/ Shaping: the OmniPCX Office
manages 2 queues in a buffer memory -
a High Priority queue and a Lower
Priority queue.
• Congestion control: the OmniPCX Office
use Random Early Detection mechanism
(RED) on the Lower Priority queue
to inform packet sources to decrease
their transmission rate.
• VoIP shares the bandwidth with the
OmniPCX Office Internet applications
(e-mail, VPN, etc.).
• Optimization: thanks to H450-based
mechanisms, IP resources and number
of compression/ decompression are
optimized, as a result QoS is improved
in situations of transfer and forwarding
within the WAN.
FoIP (Fax over IP)
The OmniPCX Office supports the T38
protocol that allows fax calls to be routed
over the IP network, as well as the
interoperability with other T38 devices.
Interoperability
• The Alcatel OmniPCX Office is H323 V2
compliant and thus is able to interact
with Alcatel and non-Alcatel systems
supporting this standard.
Direct WAN Access via a Router
IP phones can access the WAN via
a router directly connected to the LAN.
This solution is particularly suitable for
large corporate data networks.
• Policing, queuing, shaping and
congestion control are mana
ged directly
by the router.
Overflow, Backup and Optimization
Whatever the connection method,
the Alcatel OmniPCX Office provides
overflow and backup mechanisms through
ISDN, as well as IP trunking optimization.
• Overflow: when VoIP calls exceed
a given limit.
• Backup: in case of WAN link failure.
