3-10 NEC MH150/MH160 Wireless Handset Configuration
NEC MH150/MH160 Mobile Handset Administration Guide - Revision 2
Default Gateway and option 1 for the Subnet Mask. Contact the
network administrator for the proper settings for the network.
NEC MH150/MH160 Mobile Handsets cannot roam with uninterrupted service
between subnets unless specific LAN components are present. Certain AP/Ethernet
switch combinations establish a Layer-2 tunnel across subnets that enable the
handsets to roam. Without this capability, any call in progress will be dropped when
the user moves out of range and the handset must be power cycled in order to
resume functionality in the new subnet area.
Ensure that all your APs are attached to the same subnet for proper operation. The
h
andset can change subnets if DHCP is enabled and the handset is powered off
then back on when within range of APs on the new subnet. Note that the mobile
handsets cannot “roam” across subnets, since they cannot change IP addresses
while operational.
Please see NEC MH150
/MH160 Deployment Best Practices for detailed
configuration information.
• TFTP Server IP The IP address of a TFTP server on your network,
which holds software images for updating the handsets and
contains the handset files. If this feature is configured (not set to
0.0.0.0 or 255.255.255.255) with either Static IP configuration or
using DHCP option 66 (TFTP server), or the boot server/next server
(siaddr) field, the handset will check for newer software each time
it is powered on or comes back into range of your network. This
check takes only a second and ensures that all handsets in your
network are kept up-to-date with the same version of software.
• Syslog Server IP The IP address
of the syslog server. See
“Diagnostic Tools” on page 9-1 for more information.
• Ti
me Server IP The IP address of the time server.
• SVP
Server IP The IP address of the WLAN Voice Gateway. If
using Static IP configuration, this is simply the IP address of the
WLAN Voice Gateway. Note that the WLAN Voice Gateway must be
statically configured to have a permanent IP address. If DHCP is
being used, the handset will try the following, in order: the DHCP
option 151, then a DNS lookup of “SLNKSVP2” if the DHCP options
6 (DNS server) and 15 (Domain Name) are configured.
• SIP TFTP Ser
ver IP The IP address of a TFTP server on your
network, which holds SIP configuration files. In static mode, this
parameter must be configured with an IP address. In DHCP mode,
the SIP TFTP server may be specified by defining the address on
the DNS server for the name “siptftp” If this is not defined, the
address specified in option 66 will be used. See SIP Integration
Factors for more information.
• OAI Ser
ver IP The IP address of ethnic OAI Gateway. If using
Static IP configuration, this is simply the IP address of the NEC OAI
Gateway. If DHCP is being used, the handset will try the DHCP
option 152.
