1 Introduction
The DR6400 series IP routers facilitate the transmission of data over DSL, ISDN, PSTN or
wireless CDMA/GSM/3G networks.
The DR64XX provides an ADSL/2/2+/2++ interface along with a 4-port 10/100 Ethernet
switch. Optional features include CDMA 1xEV-DO 450 or GPRS/EDGE or 3G/HSDPA
wireless capability and ISDN BRI or PSTN network connectivity.
The wireless network types and data rates supported depend on the option purchased.
CDMA 1xEV-DO 450 is a standard for use in countries transitioning to digital wireless
service from Nordic Mobile Telephone (NMT) 450 analogue service, and in countries
advocating universal access for voice and data. This is a high speed technology that has
similar uses to HSDPA.
GPRS (General Packet Radio System) is an IP-based data transmission service that runs
over GSM wireless networks. It is an “always-on” protocol which means that once the
router has “attached” to the network, data can be transmitted and received on demand,
i.e. it is not necessary to make a call first.
EDGE is an enhanced version of GPRS which offers increased data transfer rates.
UMTS and HSDPA are the 3
rd
generation (3G) of GSM wireless networks, and as such
have much higher data transmission rates.
GPRS/EDGE routing is ideal for applications that are characterised by frequent
transmission of relatively small amounts of data, e.g. ATMs (cash-dispenser), remote
monitoring and data collection (telemetry) and credit/debt card authorisation.
UMTS/HSDPA routing is ideal for larger amounts of data or for situations where the speed
of data transfer is critical. Typical applications include backup for broadband wireline
services, video transmission, etc.
The routers can be configured either by using commands entered at the serial port (much
like a modem), or via the built-in Web interface. We recommend that you use the Web
interface whenever possible.
In addition to many standard LAN and Internet protocols such as PPP, DR series products
provide a combination of powerful but easy to use configuration, management and
diagnostic tools. This makes it a simple and cost-effective solution for migrating existing
terminal or telemetry equipment from older networks to DSL broadband.

Features
The front panel of the unit incorporates a number of LED indicators depending on the
model, as shown in the following illustration (DR6410):

USB Host Connectors
The USB host connectors may be used to connect compatible USB 2.0 client devices
such as memory sticks, serial adapters, etc. Note that the total current available to power
USB devices is collectively 0.5A (i.e. for both ports).
Status Indicators
The status indicators operate as follows:
ON
Illuminates steady red when power is applied.
LAN 0, 1, 2, 3
Illuminate steady when there is a network connection to the
associated LAN port and flash when data is transmitted/received.
DTE
Illuminates steady if a terminal is connected to the serial port and
the DTR signal is on. Flashes when data is transmitted/received.
DSL
Constant red - no DSL is detected.
Quick red flash - DSL is detected and unit is trying to train up to
the DSL signal.
Constant green - DSL is active.
Flashing green - Data is being transferred.
W-WAN
NET
- Illuminates steady when a wireless network has been
detected.
SIM
- Illuminates steady when a valid SIM card is installed in the
unit.
DAT
- Flashes to indicate that data is being transferred over the
wireless network.
SIGNAL
The three indicators labelled SIGNAL illuminate to indicate the
GSM signal strength as follows:
None illuminated
< -113 dBm (effectively no signal)
1 LED illuminated
>= -112 dBm and <= -87 dBm (weak)
2 LED’s illuminated
>= -86 dBm and <= -71 dBm (medium)
3 LED’s illuminated
>= -70 dBm and <= -51 dBm (strong)
