MH110/MH120 IP Quick Start Guide
MH110/MH120 IP UNIVERGE WL Mobile Handsets are mobile handsets
for workplace IP telephone systems. This chapter contains a Quick Start
Guide, system diagram, and descriptions for MH110/MH120 IP
UNIVERGE WL Mobile Handsets.

Overview
The Wireless T elephone oper ates over an 802.11b wireless Ethernet LAN
providing users a wireless voice over IP (V oIP) extension. By seamlessly
integrating with the NEC IP telephony system, Wireless Telephone users
are provided with high-quality mobile voice communi cations throughout
the workplace. The Wireless Telephone gives users the freedom to roam
throughout the workplace while providing all the features and
functionality of an IP desk phone.
The MH110/MH120 Wireless Telephone provides a wireless extension to
the NEC VoIP solutions. The Wireless Telephone supports the Protims
protocol, a proprietary protocol developed by NEC for communication
between a NEC DtermIP-16LD and a NEC PBX.
MH110/MH120 IP Wireless Telephone Setup and Administration Guide - Revision 1
2-2 MH110/MH120 IP Quick Start Guide
The Wireless Telephones reside on the wireless LAN with other wireless
devices using Direct Sequence Spread Spectrum (DSSS) radio
technology. The handset radio transmits and receives packets at up to
11Mb/s. The MH110/MH120 Wireless Telephone supports Wired
Equivalent Privacy (WEP) as defined by the 802.11b specification. NEC
offers the product with both 40-bit and 128-bit encryption. WEP
increases the security of the wireless LAN to a level similar to a wired
Ethernet LAN.
• IP multicast addresses are used by the MH120 Wireless T elephone system. This requires
that multicasting be enabled on the subnet used for the MH110/MH120 Wireless
Telephones, SVP Server, and Telephony Gateways.
NOTE
• Routers are typically configured with filters to prevent multicast traffic from flowing outside
of specific domains. The wireless LAN can be placed on a separate VLAN or subnet to
reduce the effects of broadcast and multicast traffic from devices in other network
segments.
Quick Start Guide
Table 2-1 MH110/MH120 Wireless Telephones Requirements
Table 2-1 describes five conditions that must be met for MH110/MH120
Wireless Telephones.
Requirements Descriptions
Wireless LAN A wireless LAN must be properly configured and
operational through the use of 802.11b wireless
access points (APs) listed on the Access Point
Compatibility matrix.
TFTP Server A TFTP Server must be available on the network
in order to load the appropriate software into the
Wireless Telephones.
Refer to Chapter 5, “License Management” for
detailed instructions for loading software on
Wireless Telephones.
NEC VoIP The supported NEC VoIP solution must be
connected to your network and completely
operational.

Requirements Descriptions
NEC SVP Serve The NEC SVP Server, which facilitates
the QoS on the wireless LAN for the Wireless
Telephones, must be on the same subnet as
the Wireless T elephones and have the proper
versions of software.
Note: Ensure you have the following versions:
• 173.xxx svp100.toc
• 174.xxx zvmlinux
• 175.xxx flashfs
Wireless Telephone Configure your Wireless Telephone to ensure
that it is associated with the Wireless LAN, has
the appropriate software, and has the correct IP
address for the supported NEC IP telephony
system.

mobile workplace use within a facility using the supported NEC IP
telephony system and 802.11b APs in a wireless LAN.
The MH110/MH120 functionality is provided by emulating the NEC
DtermIP-16LD. Among other features, the Mobile Handset can receiv e
calls directly, receive transferred calls, transfer calls to other
extensions, and make outside and long distance calls (subject to the
restrictions applied in your facility.) The Mobile Handsets are to be
used on-premises; they are not cellular or satellite phones.
UNIVERGE WL Mobile Handsets use Direct Sequence Spread Spectrum
radio technology (DSSS) to transmit audio packets over wireless LAN
APs that support SVP Server.
mechanism that is implemented in the Mobile Handset and AP to
enhance voice quality over the wireless network. SVP Server gives
preference to voice packets over data packets on the wireless medium,
increasing the probability that all voice packets are transmitted
efficiently and with minimum or no delay. SVP Server is fully
compatible with the IEEE 802.11b standards.
The SVP Server is an Ethernet LAN appliance that works
with the AP to provide QoS on the wireless LAN. All Protims packets to
and from the MH110/MH120 pass through the SVP Server and are
encapsulated for prioritization as they are routed to and from the
supported NEC VoIP solution or other Mobile Handset.
SVP Server is required for QoS because the current IEEE 802.11b
wireless LAN standard provides no mechanism for differentiating
audio packets from data packets. This standard is undergoing revision
to version 802.11e to provide all the functionality of SVP Server in an
industry standard, thus ensuring high-quality voice in a mixed client
environment. Once 802.11e is ratified, NEC and its 802.11b
technology partners will adopt the new specification.
provide the connection between the wired Ethernet LAN and the
wireless (802.11b) LAN. Access points must be positioned i n all areas
where Mobile Handsets will be used. The number and placement of
access points will affect the coverage area and capacity of the wireless
system. Typically, the requirements for use of MH110/MH120 are
similar to that of wireless data devices.
Access points must utilize SVP Server. Contact NEC, or a certified
NEC distributor, for information about APs that support SVP Server.
