DTS, and DECT) and the PSTN (ISDN, CAS, DPNSS and analog) and
also houses the DSP resources for handling tones, conferencing, packet
switching towards IP Phones (SIP and H.323) and to convert media
between different protocols.
Furthermore, a new feature introduced with MX-ONE 5.0 enables the
media gateway to run in software, meaning there is no need for dedi-
cated media gateway hardware in IP only installations. The software
based media gateway can reside in the same Linux machine as the Call
Manager, thus reducing the customer footprint.
Scalability - MX-ONE allows organizations to easily expand its capacity,
add functionalities, modules, gateways, and easily upgrade the servers.
A single MX-ONE can scale from 50 users up to several hundred thou-
sand users using a mixture of IP/SIP, mobile, digital, analog, and cord-
less extensions, organizations can benefit on the expand-as-you-grow
principle of adding users in the system.
Flexible deployment - MX-ONE is a highly flexible solution that
supports a completely distributed model for deployment and design;
Servers and Media gateways within a system can be spread over a wide
area network in order to create solutions for small and large customers
across geographical locations or as a centralized system with the
servers on a central location. Depending on requirements for local PSTN
access and survivability in the event of WAN failure, remote sites can be
equipped with a remote server and media gateway combination - a
remote media gateway, with a survivable branch gateway (MX-ONE
SBG) or with IP telephones only.
High Availability - MX-ONE Telephony System offers high availability
by supporting different types of redundancy to cater to different types
and requirements of the Enterprises.
MX-ONE Telephony System offers far-reaching alternatives for High
Availability:
Server redundancy delivering high availability:
• Home Location Register redundancy (HLR)
• 1+1 server redundancy and network redundancy
• N+1 server redundancy and network redundancy
• High Availability provided via virtualization
Note: HLR redundancy can be combined with the other redundancy
features. MX-ONE gateways (Lite and Classic) can also be configured
in a redundant way, when MGU board is used.
There are two possibilities of network redundancy for an MX-ONE 5.0
Gateway:
• Bonding/Link failover
• Dual subnet (not supported for new sales)
