1 Introduction
iSurf series of IAD (Integrated Access Device) products are designed for service providers that
offer both data and voice services over a high speed data access network.
iSurf helps service providers to rapidly reach out customer base. Newer generation of
telecommunication networks provide advanced services over a common infrastructure based on
IP (Internet protocol). However, a lot of legacy devices, e.g. analogue phones, and fax devices,
are not IP capable. iSurf is positioned for use in office or home environment, as a gateway for
legacy voice or fax devices to access services provided by advanced IP networks. With iSurf,
end users are not required to replace their legacy devices.
iSurf also helps service providers to better control data traffic at edge of their networks, so as to
ensure QoS (Quality of Services) for other users in the same network. iSurf series of products
are equipped with advance capability to differentiate end user traffic, marks traffic with different
priorities, and policing traffic at the edge of their networks. These capability are vital for service
providers to avoid service disruption caused by malicious users.
iSurf series of products provide multiple management interfaces to allow easy provision and
maintenance, e.g. console access, telnet, web based interfaces, and SNMP(Simple Network
Management Protocol) management interfaces for advanced network management systems.
Service providers are given a lot of flexibilities to provision and maintain the devices even after
they are rolled out into end user’s premises.

This manual provides reference information necessary for configuration and provisioning of iSurf
products. It can also be used by technical support engineers for troubleshooting and problem
resolution. A simplified manual for end-users can be provided upon request.

Indicator Description Function
1-8 Indicators for POTS
Interfaces to Analog
Phones or Fax
Stable Light indicates an POTS interface for phones or
faxes is not in use or faulty.
Stable OFF indicates a POTS interface is ready for use.
Flashing Light indicates a call is in progress via certain
POTS.
2.1.2 Rear Panel
Table 2 Interfaces in Real Panel
Interface Function Description
12DVC Power Input Jack Use 12V /1.5A DC Power adapter supplied with iSurf.
Misuse of power may cause damage to the device.
Reset Reset button,
which is sunk
slightly below
surface of rear
panel
To reset system configuration to factory default, turn off
power first. Press the Reset button and keep holding it
before turning on power again. When power supply is
turned on, the RUN indicator in the top panel will flash fast
initially, with 0.25 sec ON and 0.25 sec OFF, which
indicates the system is booting. Keep holding the Rest
button for about 1 minute until the RUN indicator start
flashing in a unbalanced pattern with light ON for 1.5 sec
and OFF for 0.5 sec, which indicates the system is
restoring factory default value. The Reset button may be
released then, however, the system may take 30 seconds
or longer to complete boot-up process.
Console Serial interface for
Console Access Command Line user interface, offer Local Console management.
WAN RJ45 Interface to
Wide Area
Network
Wide Area Network interface (RJ45), to connect
xDSL/Cable mode or Ethernet
LAN RJ45 Interface to
Local Area
Network
Local Area Network interface (RJ45), to connect to
computer, or a hub or switch.
Phones 1-8 RJ11 Interfaces to
Legacy Phones
and Fax
Depending on its model, an iSurf may provide different
number of RJ11 ports for legacy phones or fax machines.
iSurf 1004 provides 4 ports. iSurf 1008 provides 8 ports.

Interface Function Description
Life Line RJ11 interface to
PSTN If a customer prefer, he may retain one analogue line provided by PSTN service provider. This line can be
connected to the Life interface and is shared amongst all
phones and fax machines. When there is power outage,
outgoing calls from all local phones and fax machines will
be routed to this escape interface. However, only one local
phone can make call at one time.
