ItdoesnotmatterwhereDMEisconnectedonaNetwork,itwillstillbeable
to receive Message Updates automatically. It is normal for DME to be
installedneartheTelephoneSystemController(KSU)whereanLIUshould
be installed. If DME is to be installed away from this point, then the Audio
output from DME can be routed to the LIU via 2 wires of a CAT5 cable.
For ease of installation, DME uses DHCP technology. This means that
theinternalNetworkIPAddress forDME willbeassignedautomatically
by the Network Internet Router/Switch as soon as it is connected. This
process is quick and automatic. Once complete it will allow DME to
access the Internet so that it can connect to your FTP Server to check
for Message or Settings updates.
DME uses FTP update technology, as this is the simplest and most
reliable method, because it avoids most potential Network Security
(Firewall) issues. With the FTP method, DME makes an outgoing
connection from the customers network to a remote FTP Server. This
type of connection is free from most of the complex and ever changing
settingsassociatedwithanIncomingconnectiontoacustomernetwork,
necessary to provide network security.
Dealers using DME should arrange for use of an FTP Server with their
existingISPorotherrecommendedsupplier.Thiswillinvolvea setupfee
and small ongoing rental fee which will depend on the memory space
requiredonthe FTP Server. A Dealer can alternativelysetup their own
FTPserver.
A short time after DME is first connected to a Network, it will make its

are present, it will automatically Add or Delete up to 15 files at a time.
