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.

Page 8
Figure 2 illustrates connections from iSurf 1004 to other devices in a customer premise network.
1. POTS lines: Connect phones and fax machines to one of the RJ-11 jacks in rear panel.
2. WAN: Connect an Ethernet cable from xDSL/Cable modem to the RJ45 jack for WAN
(Wide Area Network) in rear panel
3. LAN: Connect an Ethernet cable from your computer ’s network adapter to the RJ45 jack
for LAN (Local Area Network) in real panel. An Ethernet switch or hub can also be used
to provide more Ethernet ports for more computers.
4. Power: After connect to power source, iSurf will start up automatically. It may take 30
seconds or longer for iSurf to fully complete the boot-up process.
In Figure 2 all four FXS ports of an iSurf 1004 have been fully utilized. If there are still idle ports
available, it is recommended, but not necessary, to power off iSurf before connecting new
devices.
3.3 Example Configuration
This section shows a quick example on how iSurf works with an service provider’s offering voice
services based on SIP (Session Negotiation Protocol).
Caution Configuration data discussed in this section is for illustration
purpose only. Actual configuration may differ depending on your
service provider network scenario.
SIP is an application layer signaling-control protocol used to establish, maintain, and terminate
multimedia sessions. Multimedia sessions include internet telephony, conference, and other
similar applications involving such media as audio, video, and data.
iSurf may initiates SIP call requests to other SIP capable node. If an calling party knows IP
address of the called party, the calling party may initiate a call request directly to the called party.
However, in a large network, such intelligence is difficult to maintain by end points. Service
providers’ infrastructure plays an vital role in facilitating telecommunications communication.
A large scale telecommunication network typically consists of the following components:
SIP Clients: SIP Clients, also widely referred as User Agents, typically represent
subscriber devices that are capable of initiating and accepting SIP calls. A SIP
client is identified by its SIP address, e.g. bob@myserviceprovider.com. The
format of SIP addresses is very similar to an email address. In many
networks, it may also appear as <Dial Number>@myserviceprovider.com.
Dial Number is a string of numeric digits. SIP Addresses and Dial Numbers
should be provided by Service Provider before commissioning an iSurf.
Registrar: Registrar authenticate SIP Clients and maintain their status. Each SIP Client
is required to register itself to Registrar periodically and announce its latest IP
address. In this way IP addresses of all SIP clients in the network are updated,
Proxy may look up IP address of a called party using Dial Number or SIP
address. The IP address or host name of Registrar should be provided by
Service Provider to configure an iSurf. In certain networks, Proxy may forward
registration messages to Registrar, as such IP address of Registrar can be
specified the same as the IP address of Proxy.
Proxy Proxy performs network address translation, and assists in locating called
iSurf 1004/1008 User Manuals
Page 9
party. Proxy may also inter-work with other service providers’ networks if the
called party is outside boundary of the network, while a end user may not
have the permission to do so. The IP address or hostname of the Proxy
should be provided by Service Provider.
Figure 3 SIP Capable Network Elements in a VoIP Network
3.3.1 Establish Network Connectivity
Connect WAN port of iSurf to an Ethernet port provided by service provider, e.g. a port in Cable
Modem or DSL Modem. Assuming the network do not require any authentication to issue an IP
address, iSurf will acquire an IP address for its WAN interface through DHCP.
Default IP address of iSurf’s LAN interface is 192.168.0.1. By default iSurf also serves as an
DHCP server for the LAN segment. It allocates addresses in 192.168.0.2-244 range to
requesting IP address by DHCP. NAT is enabled between the LAN segment and the WAN
segment.
Change TCP/IP settings of your PC to DHCP mode. Connect your PC to LAN interface of the
iSurf IAD, make sure your PC acquires an IP address. You should be able to PING the IP
address LAN interface of iSurf IAD 192.168.0.1, otherwise please follow guidelines in Section 4.1
to troubleshoot. Launch web browser to visit http://192.168.0.1
. A small window will pop up and
ask for user name and password. Fill in the default user name and password.
Username: admin
Password: admin
iSurf 1004/1008 User Manuals
Page 10
You will be brought into the web administration interface provided by the iSurf IAD.
Figure 4 iSurf's Web Management Interface
Verify that WAN interface is up, otherwise follow guidelines in later sections to trouble shoot.
3.3.2 Example SIP Configuration
The example configuration assumes the following concerning the service provider.
Registrar’s IP Address Not used. Proxy server forwards relevant SIP
messages to Registrar.
Proxy’s IP address 202.156.1.248
Dial Number of the analogue phone 85412006
SIP Address for analogue Phone 85412006@myisp.net
Password for the above SIP address: pass2006
Each iSurf 1004 unit provides four interfaces for POTS devices. The following configuration
assumes an analogue phone is connected to FXS port 1.
iSurf 1004/1008 User Manuals
Page 11
Click on “SIP Configurations” in the left area of the browser window:
Fill in the following in “UA Configuration” section.
UA stands for User Agent. Internally FXS ports are counted from 0. Phone port 1 maps to Port No
0 internally. The “User ID” maps to dial number. Apply settings after changes are made.
Next comes to Registrar configurations.
When “Enable Register” is enabled, registration message will be sent out. However when “Use
Proxy as Registrar” is enabled, registration messages are sent to the IP address of Proxy.
When “Enable Register” is disabled, iSurf may be configured for point to point communications,
which is typically used by multi-site enterprises. Apply settings after changes are made.
Next comes to SIP Configurations.
iSurf 1004/1008 User Manuals
Page 12
If more than one Proxy Address are supplied, an iSurf IAD will try each Proxy sequentially if a
request times out. Apply settings after changes are made.
After complete all settings, you may uncheck “Enable Register” and apply settings to de-register
the iSurf. Check “Enable Register” and Apply settings again to perform a new registration. If an
registration is successful, the “Port Status” under “UA Configurations” should show “Register
Success”.
Configure another iSurf in a similar way. The only difference is the Dial Number and SIP Address.
Dial Number of the analogue phone 85412010
SIP Address for analogue phone 85412010@myisp.net
If both iSurf register successfully, make a call from the phone 85412006 to another phone
85412010 by dialing 85412010 at the phone pad.
Save configuration data by pressing [Save Data] button.

Connect LAN port of the Control Station (a PC) directly to the LAN port of iSurf. Figure 10 shows
an indirect connection between the Control Station and iSurf, via an Ethernet hub.
Figure 10 Telnet Access into iSurf from LAN Segment
iSurf also acts as an DHCP server for hosts in LAN segment by default, unless this feature is
disabled. Control Station may dynamically acquires an IP address from iSurf’s built-in DHCP
server.
After IP layer connectivity is established between the Control Station and iSurf, the reader may
Telnet into the iSurf.
4.2.2 Telnet Access from WAN Segment
The reader may also Telnet into iSurf IAD by specifying IP address of iSurf’s WAN interface.
Access from WAN interface is very helpful for remote troubleshooting.
CAUTION Telnet from remote location is not recommended as user name and
password are sent in clear text. Malicious users may sniff IP packets
and find administrator’s credentials easily.
The WAN interface of iSurf does not have an static IP address by default. iSurf must be properly
configured to acquired an IP address, usually by DHCP or PPPoE, from service provider’s
network.
iSurf 1004/1008 User Manuals
Page 18
When the iSurf IAD is operational, the WAN interface must have acquired an IP address. Support
technician may seek end user’s help to find out IP address of the WAN interface of an iSurf IAD
located in customer premise. The most easy way for end users is to follow the instructions
outlined in Section 4.3.1. End users may be given a user name and password with lower
privilege to access limited information stored in an iSurf IAD.
Figure 11 Telnet into iSurf IAD from WAN Segment
4.3 Managing iSurf IAD from a Web Brower
It is also possible to manage iSurf IAD from a web browser in a remote host, for example,
Internet Explorer in Windows operation systems.
The reader has the option to access the IAD from the LAN segment, or from the WAN segment.
• The default IP address for the LAN interface is 192.168.0.1, unless the configuration has
been modified.
• The IP address for the WAN interface is usually acquired from service provider’s network
after iSurf boots up.
If neither of these two addresses is known, the reader is advised to investigate IP address by
following instructions given in Section 4.1.
4.3.1 Access iSurf’s from LAN Segment
Connect the LAN port of Control Station (a PC) directly to the LAN port of iSurf, or in-indirectly via
a Ethernet hub or switch.

4.3.2 Access iSurf’s from WAN Segment
Service providers also manage an iSurf IAD from remote, by specifying the IP address of the
WAN interface of an iSurf IAD’s in a customer’s premise. Access from the WAN interface is very
helpful for remote troubleshooting.
The WAN interface does not have an static IP address by default. An iSurf IAD must be properly
configured to acquired an IP address, usually by DHCP or PPPoE, from the provider’s network.
When a iSurf IAD is operational, the WAN interface must have acquired an IP address. Support
technician may seek end user’s help to find out the IP address of WAN interface of an iSurf IAD
located in customer premise. The easiest way for end users is to follow the instructions outlined
in Section 4.3.1. End users may be given a user name and password with lower privilege to
access limited information stored in an iSurf IAD.

5.4 User Management
iSurf IAD implemented two levels of user privileges, for administrators and end users.
• Administrator’s privilege allows full control of the iSurf system, e.g. system software
upgrades. Administrator’s privilege provides maximum flexibility for service providers to
integrate the iSurf with its network.
• Operator’s privilege allows assess to a subset of features and parameters that are
customer specific. Parameters that are prone to cause operational failure are forbidden
from access, e.g. change of dial number.
The system may support up to 15 users, each user has its user name, privilege level, preferred
language, and password.
User name is the only identifier of the user, which constitute by up to 17
alphanumerical characters, or up to 7 Chinese characters.
Level is the privilege level of a certain user. It could be Administrator or
Operator. Only users with Administrator level may create/modify the
privilege of other accounts.
Language defines default display language of web management pages for a user.

5.4.3 ACL(Access Control List) Management
ACL (access control list) provides enhanced security by restricting access to iSurf IAD according
to IP address of the remote station. Hosts whose IP address in subnets defined by ACLs are
permitted to access the IAD, while the access from other hosts are forbidden.
ACLs are effective for access by telnet, web or SNMP management interfaces.
Click on “User Management” in the Configuration Tree, scroll down the detailed configuration
window. The following information are shown:
An ACL consists of an network IP address(network address) and Subnet Mask, hosts with in IP
address range 10.10.0.1 to 10.10.0.254 are be able to access the system in this case.
In the “Current ACL” table, the first entry shows an entry, with network IP address of 0.0.0.0, and
Subnet mask of 0.0.0.0. It means access from hosts with any IP address are not restricted.
The web page also allows administrators to to add/deleted/modify ACLs.
Warning: Before deleting the default ACL which with network address of
0.0.0.0, the administrator is advised to add its own subnet.
Otherwise the connection will closed, access from any IP address
will be forbidden unless the iSurf IAD is reset.

6 Network Configurations via Web Interfaces
This section discusses the configuration to establish connectivity between an iSurf IAD with a
VoIP core network.
iSurf IAD serves as a gateway for legacy phones and faxes.
• The WAN (wide area network) interface of an iSurf IAD should be used interface with
VoIP core network.
• The LAN interface is primarily used to provide data connectivity to IP hosts, e.g. PCs, in a
customer premise.
Figure 14 iSurf as a Gateway for Customer Premise Network
Warning Although LAN interface may also be used to interface with VoIP
network, it is not advised to do so.
Network configurations concern IP addressing, NAT (Network Address Translation) between the
LAN and WAN segments, separation of voice and data by VLAN, and QoS, etc.
6.1 IP Configuration
Click on “IP Configuration” in the Configuration Tree. The web page in the detailed configuration
frame will show IP address configuration, static routes, and ARP table.
iSurf 1004/1008 User Manuals
Page 32
6.1.1 IP Address Configuration
Chose wan1 or lan1 from the drop down list. The interfaces can be shut down or brought up at
electrical level. When the interface is up, the interface can be enabled or disabled at logical level.
The interfaces may acquire an IP address dynamically, or be given a static IP address.
The configuration of interface lan1 can only be shown but not changeable.
6.1.2 Static Route Configuration
Static routes can be specified. A default route is set by iSurf when wan1 interface acquires an IP
address by DHCP or PPPoE. The combination of Destination 0.0.0.0 and NetMask of 0.0.0.0
means all traffic is sent to the default Gateway, which is 10.224.53.254 in the table.
Multiple static routes to the same destination may coexists simultaneously. Their priorities are
differentiated by respective Pref values. The route with smallest positive Pref value will be
elected as the active route. Negative Pref value indicates that an gateway is not reachable.
6.1.3 ARP table and Configuration
In Ethernet networks, a host must translate an destination IP address to a destination MAC
address at data link layer, in order to send an IP packet to another host in the same LAN
segment. Such an translation is achieved by looking up an ARP table. An example is shown in
the ARP table. If no match can be found, the IP packet is sent to the MAC address of default
gateway.
iSurf 1004/1008 User Manuals
Page 33
Entries in the ARP table is learned through Address Resolution Protocol, which defined a number
of ways for network elements in a network elements to announce its own MAC address, to
inquire an MAC address for certain IP address by broadcasting, etc.
Entries in the MAC table can be also modified if necessary.
6.2 PPPoE Configuration
PPPoE is widely used to allow per flow traffic control in service provider’s network.
The configuration is relatively simple. Enable PPPoE feature and fill in username and password.
Apply the settings. Save the configuration. Reset iSurf to effect the changes. PPPoE feature by
default is applied to the wan1 Ethernet interface.
Notice iSurf IAD must be reset to effect PPPoE configurations changes.
6.3 NAT Configuration
Public IP addresses has been depleting with explosive growth of the Internet. As such many
private networks, e.g. corporate networks or customer premise networks use private IP
addresses. These private networks may use overlapping address and is not reachable by hosts
from public domain by routing.
NAT(Network Address Translation) allows multiple hosts with private IP addresses to share one
public IP address, which is usually assigned to the WAN interface. The Source Address, and
Source Port fields in the IP header of packets from private LAN segments, are translated by iSurf
IAD to the public IP address of WAN interface, and an un-used port.
iSurf 1004/1008 User Manuals
Page 34
NAT feature is enabled by default. The “Maximum Session of Each IP” limits the over loading of a
public IP address. It also implies that maximum 256 hosts may be accommodated in the LAN
segments.
6.4 DHCP Server Configuration
iSurf may serve as an DHCP server for the LAN segment.
Click on “DHCP Server Configuration” in the Configuration Tree. A few aspects of DHCP Server
feature can be specified in the detailed configuration frame in the right area of browser window.
By default this DHCP server feature is enabled for LAN segment.
Note NAT must be enabled to if DHCP server is enabled. DHCP server is
enabled by default.
A default IP address pool is allocated by the iSurf IAD. It is not recommend to change this
settings in general. If readers do wish to specify an IP pool manually, please be reminded that the
Gateway for LAN segment should be the IP address of iSurf’s LAN interface.
Notice The Gateway for LAN segment is usually the LAN interface of an
iSurf IAD. If the IP pool for DHCP server is modified to another
subnets, e.g. 192.168.1.0/24, the Gateway and IP address for the LAN
interface iSurf should be modified accordingly.
iSurf 1004/1008 User Manuals
Page 35
As an option, DHCP server may provide a few DNS servers’ to client PCs requesting an IP
address.
When wan1 interface acquires an IP address from the network, it is likely that information of DNS
servers is provided by the DHCP servers in the network. Manual setting is not necessary.
It is also possible to manually specify DNS server address in the table above.
6.5 QoS Marking and VLAN Configuration
VLAN(Virtual Local Area Network) allows separation of traffic by an VLAN ID at layer two of the
seven-layer OSI network model. VLAN may facilitate implementation of security measures, and
QoS treatment.
The iSurf IAD internally classifies traffic into three types, Voice, Signaling, and Data. The traffic
types can be tagged with designated VLAN ID.
All ingress traffics from LAN port are treated as data. More advanced techniques are discussed
in Section 6.5.3.
6.5.1 VLAN Configuration
Click on “VLAN Configuration” to access configuration related to VLAN and QoS.
VLAN tagging at wan1 interface can be enabled or disabled. VLAN ID for Voice, Signaling, and
Data can be designed in this section. .
6.5.2 QoS Configuration
Classified traffic can be marked with certain QoS priorities, at layer two or layer three of the
iSurf 1004/1008 User Manuals
Page 36
seven-layer OSI network model. At layer 2, 802.1p bits are used for QoS Marking. At layer 3, the
DSCP field in IP header is used for QoS marking.
6.5.3 Classification of Ingress Traffic
By default all ingress traffic from LAN port are treated as Data.
In response to one of our customer request, more advanced techniques has been developed, to
differentiate voice and signaling traffic generated by soft SIP user agents, running on PCs in LAN
segment. At the time the document is written, web based management interfaces are not fully
developed yet. This feature is available through command line only, accessed via either console,
or telnet.
The example below illustrates ingress traffic classification based on TCP/UDP port.

6.6 STUN Configuration
STUN (Simple Traversal of User Datagram Protocol (UDP) Through Network Address Translators
(NATs)) is a network protocol allowing clients behind NAT (or multiple NATs) to find out its public
address, the type of NAT it is behind and the internet side port associated by the NAT with a
particular local port. This information is used to set up UDP communication between two hosts
that are both behind NAT routers.
Protocols like SIP use UDP packets for the transfer of sound and/or video and/or real-time text
signaling traffic over the Internet. Unfortunately as both endpoints are often behind NAT, a
connection cannot be set up in the traditional way. This is where STUN is useful.
STUN is a client-server protocol. A VoIP phone or software package may include a STUN client,
which will send a request to a STUN server. The server then reports back to the STUN client
what the public IP address of the NAT router is, and what port was opened by the NAT to allow
incoming traffic back in to the network.
By default, a STUN server in the public domain larry.gloo.net has been configured as the
secondary server. The Service Provider may specify address of its own STUN server, if
implemented, as a primary server.
The response also allows the STUN client to determine what type of NAT is in use, as different
types of NATs handle incoming UDP packets differently. There are four main types of NAT:
• full cone NAT,
• restricted cone NAT, and
• port restricted cone NAT.
• symmetric NAT (also known as bi-directional NAT)
iSurf has built in intelligence to work with three of four main types: full cone NAT, restricted cone
NAT, and port restricted cone NAT, by pre-adjust the outgoing SIP messages and voice using
public IP address and source port discovered.
iSurf will not work with symmetric NAT (also known as bi-directional NAT).

Next comes to Registrar configurations.
When “Enable Register” is enabled, registration message will be sent out. However when “Use
Proxy as Registrar” is enabled, all registration message is sent to the IP address of the Proxy.
When “Enable Register” is disabled, iSurf may be configured for point to point communications,
which is typically used by an enterprise owning multiple office sites. Apply settings if changes are
made in the above section.
iSurf 1004/1008 User Manuals
Page 40
7.1.2 Proxy Configuration
If more than one Proxy Address are supplied, an iSurf IAD will try each Proxy sequentially if a
requests to an Proxy times out with no responses. Apply settings if changes are made in the
above section.
After completing all settings, you may uncheck “Enable Register” and apply settings to deregister the FXS port. Check “Enable Register” and apply settings again to perform another
registration. If an registration is successful, “Port Status” under “UA Configurations” should show
“Register Success”.
7.1.3 Mapping of SIP Configuration to SIP Messages
Different VoIP network equipment vendors may have implemented SIP protocol in different ways.
Table 6 summarizes the use of configuration values in various SIP messages.

In SIP standards, the “User ID” could be a mix of alphabetic and numeric digits. However, in a
network with analogue phones, “User ID” is recommended to use numeric digits only as iSurf
takes user inputs from phone pad to construct “User ID” of the called party.
The “User ID” field should consist of numeric digits only.
7.2 Number Analysis Configuration
iSurf IAD collects dial numbers from external phone or fax. Dialed digits are analyzed before
being sent out to other element in a VoIP network. Dial numbers can be modified according to
specific needs. Rules can be setup to modified a dial number, if it meets certain condition.
Click on “Number Analysis Configuration” in the Configuration Tree. Conditions and associated
actions on dial numbers are displayed in the detailed configuration window.
The conditions are defined in Call Route Configuration section. The actions are defined in
Number Change Configuration section.
7.2.1 Conditions to Modified Dial Numbers
The Current Call Route List table shows conditions that triggers certain action on a dialed
number string.
• “Number Prefix”, “Min Length of Number”, and “Max Length of Number” are used in
iSurf 1004/1008 User Manuals
Page 42
combination to define a condition.
• “Route Address” may specify another SIP capable node to route a call. If this field is left
empty, configuration in User Agents setup applies. This feature was widely used for point
to point calls without involvement of Proxy servers, in early years of VoIP network
evolution.
• “Change Index” specifies the index of an action in “Current Change List” table to be taken,
if a dial number matches with the condition.
Example in the table shows that dial numbers starting with 021, is subject to the change defined
in action 0 defined in the Current Change List.
7.2.2 Number Change Configurations
The “Number Change Configuration” section defines the actions to be taken, if a dial number
meets certain conditions defined in “Call Route Section”.
• “Index” defines the index of action.
• “Type” defines type of changes. Certain digits can be inserted into a dialed number. Digits
in a dial number can also be modified or deleted.
In the example, the change action, defined by entry with “Index” 0 in the “Current C hange List”,
inserts “8541 from the 3
rd
position of the number string.
So an dial number 0212401 is modified to 021 8541 2401 before iSurf IAD sends out a call invite.
7.3 Call Configuration
Call Configuration section defined a few behavior when a call is outgoing or incoming.
Click on “Call Configuration” in the Configuration Tree. The following sections will be displayed in
the detained configuration window:
iSurf 1004/1008 User Manuals
Page 43
7.3.1 Dial Plan Configuration
iSurf collects dial numbers from external phone or fax. Dialed digits are collected as a whole
before they are encapsulated in a call Invite message.
By default iSurf takes five second idle time after the last punch, as completion of user input. Digit
mapping are introduced to allow faster recognition of dial completion. If the dialed digits, input by
user from the phone pad, map with any pattern of DigitMaps defined in this section, collected
digits are immediately processed.
Maximum 500 digit maps can be defined. Each digit map may consists up to 2048 characters. In
the “Dial Plan(DigitMap) Configuration” textbox, each digitmap are separated by an “|” character.
The string “XX.T|XX.#|P|****” consists of four digit maps:
• “*XX” means an asterisk followed by 2 digit of any number. Dial strings matching this
pattern are used for service codes, which allows user interaction by end users, e.g
disable or enable call forwarding. Refer to 7.4 for more detailed information.
• In “XX.T”, “XX” means any digits. “.” means any number of digits. T means a timer. The
entire string means iSurf wait for T seconds after the last user punch on phone pad.
• In “XX.#”, “XX” means any digits. “.” means any number of digits. The entire string means
dialed digits can be processed by press “#” button. Whenever iSurf receives an “#”, iSurf
considers that user inputs has completed, and start processing digits before “#”
immediately.
• The last digit map “****” is defined for use iSurf itself. When user press “****”, the IP
address of iSurf is announced in the ear set of the phone.
When IP Dialing is enabled, iSurf also allows call origination to an IP address input by user from
key pads of a phone.
For example, call to 1000@10.3.50.55:5060
can be dialed by pressing the following numbers:
1000**10*3*50*55**5060.
7.3.2 Multiple Lines using a Single Account
Multiple phones may share one SIP address, or account. Refers User Agent Configuration in 7.1,
Port number 0-3 may use exactly the same “User ID”, “Auth Username”, etc. Phones connected
to any port can make outgoing calls.
In this scenario, if there is a incoming call to the “User ID”, which local phone should ring? This is
defined in “Call Parameter Configuration” in this section.
iSurf 1004/1008 User Manuals
Page 44
A few options are available in the drop down list:
• Early Release First: the line which was released earliest receives an incoming call.
• Random: an incoming call is randomly dispatched to one of the lines.
• Order: an incoming call is dispatched to lines sequentially.
7.3.3 Call Timers
A few timers are defined in this section:
• Ringback Timer: A ringback tone, or audible ringing tone or ringback signal, is the audible
ringing that is heard on the telephone line by the calling party after dialing and prior to the
call being answered at the distant end. When A calls B from an iSurf IAD, if B does not
answer the call, the “Ringback Timer” defines the maximum waiting time after which iSurf
should tear down the the call, (if A does not hang up the phone).
• Ring Timer: A ring tone is the sound made by a telephone to indicate an incoming call.
When B calls A at an iSurf IAD, if A does not answer the call, the “Ring Timer” defines the
maximum waiting time after which iSurf should tear down the call, (if B does not hang up
the phone).
• Busy Timer: when A calls B, if B is busy, the “Busy Time” defines the maximum waiting
time that iSurf should tear down the call, (if A does not hang up the phone).
• Offhook Warning Time: The maximum waiting time after which iSurf should send warning
signals to the line.
7.4 Enhanced Services Configuration
iSurf supports a rich set of supplementary services.
Click on “Enhanced Services Configuration”, the following Supplementary Service Subscription
are displayed in the right frame of browser window:
iSurf 1004/1008 User Manuals
Page 45
iSurf provide three level of control to supplementary services:
• Is the service enabled? Typically this is controlled by the service provider.
• Is the service activated? Typical this controlled by end user, e.g. he may activate “call
forwarding no answer” before he leaves his desk and go home. Users may dial services
codes to activate or activate these features. .
• What parameter should be used for certain feature, e.g. which number to forward a call?
This is specified by user by dialing the service codes, e.g. *90075533639088 specifies
that incoming calls should be forwarded to 075533639088. It is also possible to define
the parameters in a the web management page, as discussed in 7.5.
Default service codes are displayed below. Service codes are configurable.
7.5 User Settings
User Settings specify user specific parameters for supplementary services. These settings will
remain even their associated features are deactivated, so that users are not required to set them
next time.
iSurf 1004/1008 User Manuals
Page 46
Hotline refers to automatic dialing out to an pre-determined number, if a user takes a phone off
hook but dials nothing. Hotline is configured on per FXS port basis.
The following example instructs iSurf to monitor port 1, (the 2nd physical Phone port as iSurf
internally counts from 0). If the phone connected to port 1 is off-hook for 4 seconds, iSurf will dial
out to number 2006.
7.6 VoIP Configuration
Voice is sampled and coded into digital bit stream, before they are packetized into IP packets.
The following sections discusse various coders supported by iSurf.
Click on “VoIP Configuration” in the Configuration Tree to access the codec configurations.
7.6.1 Codec Configurations
iSurf 1004/1008 User Manuals
Page 47
The parameters are explained in more details:
• DTMF Transfer Mode: DMTF stands for Dual-Tone Multi-Frequency (DTMF) signaling,
which is used for transfer of telecommunication signal over the line in the voice-frequency
band in legacy PSTN networks. In VoIP networks, legacy devices continues to use DMTF
to send busy signal, Flash or alphanumerical digits. For example, a user may be required
to key in a password to join a conference call, which is sent from legacy phone as DTMF
signal, across the iSurf IAD, to the conference bridge. There are a few ways to transport
DMTF tones from legacy devices, over an VoIP network.
o Audio Stream: DTMF signals from legacy phones are packetized in RTP packets
as audio stream. Transporting DTMF user inputs as audio stream works well in a
data network with good quality. However, in networks with poor quality, packet
losses or disordered delivery of RTP packet may cause error. An alphanumerical
digit input by the caller may be interpreted wrongly as another digit.
o RFC2198: RFC2198 defined a payload format for encoding redundant audio.
o RFC2833: As a second option, iSurf can recognize the tones and translate
them into a name, such as numeric input, or Flash. RFC2833 defined payload
format for named telephone events, such as numeric input, or Flash.
o Signal: means the DTMF tones are translated to application level parameters
such as SIP.
• Echo Cancellation: can be turned ON or OFF.
• Silence Suppression: can be turned ON or OFF.
• DSP Gain: Default value is 0. It may be adjusted to increase or decrease voice volume.
• Supported Codec: iSurf supports automatic negotiation of codec with the network. The
Supported codecs, namely PCMa, PCMu, G.726, G.723, and G.729, are announced to
the called party in SIP Invite messages.
• Preferred Codec: Preferred Codec should be chosen in line with service provider’s
strategy.
• Packetization Period: The period that a voice bit stream is packetized into an IP packet.
The shorter the period, the less delay of voice. Typical values are 5, 10, 20 seconds.
• G723 Rate: G723 supports two encoding data rate. This option allows the choices of
encoding rate using G.723 encoders.
• RFC2833 Payload: The payload value to send DMTF tones according to RFC2833.
• FSK Type: Frequency-shift keying (FSK) is a form of frequency modulation in which the
modulating signal shifts the output frequency between predetermined values. DTMF is
one of the application of FSK. iSurf supports BellCore, ETSI, NTT options.
Information G.723 and G.729 cannot be enabled at same time.
Information PCMu or PCMa Law can be chosen in Line Configurations. Only one
codec can be used at a time.
Most legacy fax devices adopt ITU-T Group 3 fax protocol published in 1990. The protocol is
composed of server standards that specify different parts the fax call. Amongst them T.30
specification defined procedure to set up a fax call, determine the image size, encoding, and
transfer speed, the demarcation between pages, and the termination of the call. T.30 also
iSurf 1004/1008 User Manuals
Page 48
references the various modem standards for handshaking (V.21 Channel 2 Model at 300mbps),
and for image transfer (V.27Ter, V.29, V.17, and subsequently V.34).
The most simple approach to transfer fax over an IP network is the bypass mode. iSurf or other
gateway devices simply samples all transmissions from fax machine using PCM (Pulse-code
modulation) at 64kbps, and transport the bit string to the other gateway at edge of the network.
Figure 15 Transfer of T.30 Faxes in Transparent Mode
Transparent transfer provides no protection to packet loss, and requires big buffer in the in the
gateway device to combat network delay jitter. Tolerance of round trip delay for the IP network is
a stringent 2 seconds. Delay longer than that will cause failure of fax transmission.
More reliable and preferred method of delivery fax via an IP network is fax relay. The T.38 fax
relay standard was devised in 1998 as a way to permit faxes to be transported across IP
networks between existing G3 fax terminals.
Figure 16 Transfer of T.30 Faxes using T.38 Fax Relay
iSurf 1004/1008 User Manuals
Page 49
The configuration are explained in more details:
• Fax Mode: Transparent or T.38. The later is more preferred.
• Rate Management: Local TCF, Transferred TCF At this moment only Transferred TCF
is supported.
• UDP Error Correction: Redundancy or FEC. At this moment, only Redundancy is
supported. Redundancy method means payload transmitted in previous IP packet is
repeated in a later packet.
• Max Buffer: (100~65535)
• Max Datagram: (50~65535)
• Max Rate: 2400bps, 4800bps, 7200bps, 9600bps, 12000bps, 14400bps.
• Port Offset: (0~9)
• Send NAT T38: No or Yes. If an external session boarder gateway is implemented in the
network, choose No.
7.6.2 Media Protocol
iSurf supports multiple media gateway control protocols, e.g. MGCP, H.248, H.323, SIP. For
service providers networks, SIP will be future proof as major telecommunication standardization
bodies, e.g. 3GPP, 3GPP2 have adopted SIP as the foundation for future communication
networks
iSurf need not be reset if changes are made are at application level, e,g. IP address of Proxy,
Rather, the media protocol can be restarted to effect changes.
7.7 Line Configuration
Line configuration defines physical and electrical layer parameters, such as port transmit power.
Click on “Line Configuration” in the Configuration menu to access management web page for line
configurations.
iSurf 1004/1008 User Manuals
Page 50
7.7.1 Port Attribute
Most of the configurations are self explaining in the port attribute section.
On Port Gain settings, the value before “/” is for transmission, the one after “/” is for receiving.
The min and max hook times are relevant to the detection of a flash. If the phone is put on and
off hook quickly and the duration is between min and max hook time, the operation is considered
the same as pressing the Flash button.
7.7.2 Port Fax Attribute
The IAD allows controlling fax function by each port. Configuration page is as follows:
7.7.3 Private Number
Private numbers were used for point to point VoIP call setups without the involvement of Proxy
server. This is not required for a service provider’s network where VoIP core network
infrastructure is implemented.
iSurf 1004/1008 User Manuals
Page 51
In the scenario with no proxy servers and registrar, dial numbers must be planned carefully. Let
us use an example to elaborate this scenario.
Figure 17 iSurf Application in a Private VoIP Network
A company with three sites may plan for numbers in different ranges for each sit. This number
range must not overlap in order to make sure incoming calls are correctly routed to certain site.
Call route without the assistance of Proxy is discussed in Section 7.2 Number Analysis
Configuration. When a user site 1 at calls a number 3001 at site 3, an entry must be set up in the
Call Route Configuration, with the IP address of iSurf at site 3 manually specified.
7.7.4 Line Maintenance
iSurf may block some ports temporarily. This option maintains the user agent setting.
iSurf 1004/1008 User Manuals
Page 52
7.8 Attendant Configuration
The Attendant Configuration is used for telephone kiosks or Internet cafe. Long distance calls
can be immediately rated and paid by a the user to the attendant.
KZ Broadband Technologies supplies a light weight billing software, which allows the Attendant to
define call rate. The remote IP address refer to the IP address of the PC which the billing
software is running.
After an Attendant is defined, the ports can be defined managed or free for use:
