Migration; Sx-2000 Adjunct - Mitel 3300 General Information Manual

Migration

The Mitel SX-2000 LIGHT has long been the flagship product in Mitel's Enterprise
communication portfolio. As technology evolved, Mitel continually leveraged the rapid advances
in microprocessor technology to increase the capacity and processing power of the traditional
SX-2000 platform to benefit our customers.
Mitel has always followed the strategy of protecting our customers' communication investment
in the SX-2000 platform by allowing them to leverage their existing investments in their Mitel
solutions.
Upgrading allows a customer to make a smooth transition to IP telephony without sacrificing
the features and investment of their existing equipment. A customer can make small incremental
investments to move from the circuit-switched world to a full IP-PBX while retaining their
investment in customer premise equipment and desktop devices. On the desktop devices,
moving to IP telephony allows simplified moves, adds and changes. It also simplifies the building
cabling by sharing a single Ethernet connection with both IP telephony and the desktop PC.
For both IP telephony and traditional circuit switched telephone users, migrating to IP telephony
offers the opportunity to bypass long distance tolls by routing traditional PSTN calls across a
unmetered IP network, saving ongoing costs.
With the 3300 ICP, Mitel has delivered a highly-functional communications platform that allows
customers to migrate to IP telephony without sacrificing the features and investment in their
traditional Mitel SX-2000.
In addition to complete replacement, the 3300 ICP offers three distinct migration strategies that
can be used based on the relevant customer situation:
• SX-2000 Adjunct on page 37
• Third party PBX adjunct on page 38
• SX-2000 Control replacement on page 38

SX-2000 Adjunct

By integrating a 3300 ICP into an existing SX-2000 solution, our customer fully retains their
previous investment in Mitel equipment. The 3300 ICP connects to the SX-2000 via a DPNSS
(MSDN) connection. This connection allows many features to work transparently, and also
delivers the customer a gateway to IP telephony. This scenario is used typically if a new
workgroup is being created within a business that would benefit from IP telephony or to allow
IP telephony integration to the Wide Area Network reducing PSTN charges.
