What is Peer-to-Peer Switching?
“Peer-to-peer” switching means that the stations
participating in a call are connected directly to each other
through the IP network. The signals travel through the IP network
but do not “go through” the switch as they do in
traditional telephony. The fact that the NEAX2000 IPS can function
in and support a “hybrid” network with traditional
digital/analog switching, IP/TDM/IP switching and pure peer-to-peer
IP switching means that users can continue to utilize their
existing equipment while they phase in IP Telephony and lay
the foundation for future networks.
Reduced Costs of
Peer-to-Peer IP Connectivity
The NEAX2000 IPS retains all the features of the popular
NEAX7400ICS M100MX/NEAX2000IVS2, while offering significant
cost savings associated with peer-to-peer Telephony such as:
Converged WAN Infrastructures –
Pay for service and maintenance of one network rather than two.
By transporting voice signals across the Wide Area Network as
IP packets, users can integrate their voice traffic with their
data traffic.
Converged LAN Infrastructures –
Establish voice calls across the 10/100 Ethernet Local Area
Network utilizing the existing plant cabling and allowing single-cable
termination to the desktop.
Reduced Equipment Requirements
–
Reduce the need for cards while minimizing the required plant
footprint as well. In traditional TDM telephony, a single port
is required for each station and each tie line connection. With
IP connectivity, multiple calls are controlled through a single
10/100 Ethernet port while voice travels
directly between the user telephones.
Investment Protection
Even if you're not ready to migrate to 100% IP Telephony immediately,
the NEAX7400ICS M100MX/NEAX2000 IPS supports traditional circuitswitched
telephony(Time Division Multiplexed) on both the trunk and line
sides. This simultaneous compatibility allows current users
of NEAX systems to retain their existing TDM equipment(thus
protectingtheir original investment) as they begin to make the
migration to pure IP Telephony. All previous versions of the
NEAX2000 can be upgraded to the NEAX2000 IPS easily and inexpensively.
Functions Alone or in a Network
The NEAX2000 IPS functions as a standalone telephony system
supporting both IP and traditional circuit switched connectivity.
As such, it can support up to 512 stations and 240 digital trunks.
Yet it can also be networked with full feature transparency
into a system with other NEC telephony devices such as the NEAX2000IVS2,
the NEAX2400 IPX and, of course, other NEAX2000 IPS units. In
this case, the NEAX2000 IPS supports node-to-node peer-to-peer
connectivity. Up to 255 NEAX2000 IPS nodes can be networked
together.
The Bottom Line
The NEAX2000 IPS offers the full range of PBX features while
utilizing less equipment and occupying less floor space than
a traditional PBX. Additionally, NEC's broad range of IP phone
sets all have a multi-port switch built in, thereby enabling
onecable termination to the desktop. Furthermore, with NEC's
migration strategy, you can switch to IP Telephony now or
in the future while protecting your investment.
