17Preface
This chapter introduces the key features of the TA.
1.1 About your TA
The Omni.Net Lite is an ISDN Terminal Adapter (TA) with S/T interface, equipped with two
phone ports for connecting to analog phones and/or fax devices. It also supports
supplementary services such as call hold, call transfer, call waiting and 3-way conference
calling. It can transmit data at the rate of up to 230 Kbps through the RS-232 cable to your
computer or terminal.
1.1.1 TA Features
Omni.Net Lite User’s Guide
CHAPTER1
Introduction
The following sections describe features of the TA.
1.1.1.1 ISDN Basic Rate Interface (BRI) Support
The TA supports a single BRI. A BRI offers two 64 Kbps channels, which can be used
independently for two destinations or be bundled to speed up data transfer.
1.1.1.2 Extensive Analog Phone Support
The TA is equipped with two standard phone jacks for you to connect analog devices such as
telephones and FAX machines. It also supports supplementary services such as call waiting
and 3-way calling.
1.1.1.3 Outgoing Data Call Bumping Support
Call bumping is a feature that allows the TA to manage an MP bundle dynamically, dropping
or reconnecting a B-channel in a bundle when necessary.
1.1.1.4 PPP Multilink
The TA can bundle multiple links in a single connection using PPP Multilink Protocol (MP/
MLP/MLPPP). The number of links can be either statically configured or dynamically
managed based on traffic demand.
Chapter 1 Introduction18
Omni.Net Lite User’s Guide
1.1.1.5 Bandwidth-On-Demand
The TA dynamically allocates bandwidth by dialing and dropping connections according to
traffic demand.
1.1.1.6 PAP and CHAP Security
The TA supports PAP (Password Authentication Protocol) and CHAP (Challenge Handshake
Authentication Protocol). CHAP is more secure than PAP; however, PAP is readily available
on more platforms.
1.1.1.7 Upgrade Firmware
Upgrade firmware using Terminal Emulation software such as Hyperterminal.
1.1.1.8 Supplementary Voice Features
To take full advantage of the supplementary voice services available through the TA's phone
ports, you will need to subscribe to your phone company for them. The TA supports the
following supplementary voice features on both of its analog, or POTS (Plain Old Telephone
Service), phone ports:
• Call Waiting
• Three Way Calling
• Call Transfer
• Call Forwarding
1.1.1.9 Switch Type
The TA supports the DSS-1 switch type.
1.1.2 TA and ISDN Interfaces
The TA comes with an S/T interface that connects to an NT-1 (Network Termination 1) device
(supplied by the phone company in Europe).
In the following figure:
• All devices that are designed for ISDN are designated Terminal Equipment 1 (TE1).
• All other communication devices that are not ISDN capable, but have a POTS telephone
interface (also called the R interface), including ordinary analog telephones, FAX
machines, and modems, are designated Terminal Equipment 2 (TE2).
• The Terminal Adapter (TA) connects a TE2 device to an ISDN S/T bus.

2.4.1 Introduction to PPP
Point-To-Point Protocol (PPP) is designed for simple one-to-one links. These links provide
full-duplex, simultaneous, bi-directional operation, and are assumed to deliver packets in
order. PPP is intended to provide a common solution for easy connection for a wide variety of
hosts, bridges and routers.
In the process of configuring, maintaining and terminating the point-to-point link, PPP goes
through several distinct phases, as specified in the following simplified state diagram:
Chapter 2 Using the Utility28
Omni.Net Lite User’s Guide
Figure 5 Point-to-Point Link Pathway
2.4.2 Multilink PPP (MP or MLP)
There are two B channels in basic rate ISDN. This offers the possibility of opening multiple
simultaneous channels between systems giving users additional bandwidth on demand.
Multilink PPP is a method for bundling both B-channels into one PPP link for higher
throughput.
Multilink PPP must be negotiated in the establish-link phase by both peers. If the negotiation
is successful, the second link will be dialed after the first link reaches network phase. In some
countries the directory number is not the same for both channels. For dialing the second Bchannel with a different directory number, both numbers must be obtained before dialing out
unless the peer supports BACP and BAP, which will be described later in this chapter.
Multilink PPP is described in RFC-1990.
2.4.3 BACP and BAP
Bandwidth Allocation Control Protocol (BACP) and Bandwidth Allocation Protocol (BAP) is
used for call request and link drop under Multilink PPP.
BACP is negotiated during the network phase. Without BACP/BAP, the directory numbers of
both B-channels must be specified before dialing out. In some cases, it is not possible for the
ISP to support more than one chassis that is capable of bundling both channels at the same
time. With BACP/BAP, the second B-channel directory number can be obtained while
requesting a call. The second directory number is not necessary any more.
29Chapter 2 Using the Utility
2.4.4 ISDN Protocols
HDLC (High-Level Data Link Control) is one of the most common data link (layer 2)
protocols. It supports both half duplex and full duplex communication lines, point to point
(peer to peer) and multi-point networks, and switched or non-switched channels. It permits
synchronous, code-transparent data transmission.
The TA supports the following protocols.

networks to provide data transmission services. However, it is now also used as
the link layer for telematic services (as defined in T.90) in ISDN. These services
include both ISDN circuit-switched mode (DTE-DTE communication) and ISDN
packet-switched mode (DTE-DCE communication). DCE (Data Communication
Equipment) is a device, such as a modem, that converts data between different

2.5 RS-232 Port: PPP/MP Parameters
This section shows you how to configure PPP or MP parameters.
2.5.1 Link Authentication
After a link is established, it is necessary to authenticate the peer for security reasons. There
are two popular authentication methods. One is Password Authentication Protocol (PAP) and
the other is Challenge Handshake Authentication Protocol (CHAP). PAP is less secure
because it transmits the username/password in plain text form. Unlike PAP, CHAP transmits
the username/password in encrypted form. Some ISPs may support CHAP as the only method
for authentication.
2.5.1.1 Windows Authentication
For those applications that do not support CHAP, the TA converts CHAP into PAP. It is
recommended that you select Allow unsecured password in the Dial-up Connection
Property Security screen on Windows 2000/XP or do not select the Required encrypted
password checkbox in the Dial-up Connection Property Server Types screen on
Windows 95/98 by right-clicking on the dial-up connection icon (see the figures below), since
Microsoft uses MS-CHAP for username and password encryption but MS-CHAP is not
supported by most ISPs.

If you choose MLP 128K (dynamic or fixed) in the utility (see Figure 10 on page 35) or using
the ATC0=8CI=1 command, the TA needs the username and password in plain text form to
establish the connection. Do not select Enable CHAP in the PPP/MP Parameters screen.
CHAP is described in RFC-1994 and PAP is described in RFC-1334.
2.5.2 Call Bumping (Bandwidth Release) for Voice Calls
While dynamic Multilink PPP is active and you place or answer a voice call from a device that
is attached to one of the PHONE ports,the TA automatically drops one of the channels and
assigns it to voice calls. If you subscribe to the call waiting service from your local telephone
company, the TA will also drop one of the channels and answer the incoming call. Once a
voice call ends, the TA automatically re-establishes the channel depending on the BOD rule.
2.5.3 Bandwidth On Demand (BOD)
In multilink PPP mode, use BOD to bring up or drop a B-channel depending on current data
traffic. If there is light traffic on the link, one of the channels will be dropped automatically.
On the other hand, if only one B-channel is used and data traffic is high enough, BOD will
bring up the second B-channel to increase the bandwidth of the data link.
The BOD function is only effective on your TA.
For BOD, there are three parameters to set high/low threshold and persist time. Traffic
utilization is measured in the ISDN link. Highly compressible data may not generate enough
traffic to start the second B-channel. Both add-persist time and subtract-persist time must be
set to activate BOD.
Chapter 2 Using the Utility34
Omni.Net Lite User’s Guide
Note: The high threshold must be greater than the low threshold, otherwise, both of
them will be reset to the default.

2.6 RS-232 Port: V.24 Signal
The V.24 signal screen describes ways to treat data control signal for data transmitted via the
RS-232 serial interface of the TA. You can also use this screen to configure how to control
data flow between the computer and the TA.
2.6.1 RS-232 Flow Control
RS-232 Flow control is used to control data flow between devices, such as two modems or a
computer and a modem, using a serial connection. Standard flow control protocols include
hardware (RTS/CTS) flow control and software (XON/XOFF) flow control.
The RTS (Request To Send) and CTS (Clear to Send) lines of a RS-232 serial cable signal
flow control handshaking. In the following example, A is a TA and B is a computer. For
upstream traffic from B to A, when device A’s receive buffer is nearly full, it lowers the CTS
line (the CTS LED is off) to signal device B to stop sending data. When A is ready for new
incoming data, it raises the CTS signal (the CTS LED is on) to resume transmissiom. For
downstream traffic from A to B, B sets the RTS line to have A stop or restart sending data.
Figure 11 CTS/RTS Handshake
Flow control can also be done using the XON character (by pressing Ctrl-Q on the keyboard)
and XOFF characters (by pressing Ctrl-S) in a data stream. When a device receives an XOFF
signal from another device, it suspends or stops data transmitting to that device until receiving
an XON (Ctrl-Q) signal from the same device. An XOFF character is sent when the receive
buffer is nearly full. An XON signal is sent when the buffer is no longer full. Binary files may
contain these signal characters and cannot be sent with XON/XOFF flow control protocol.
Chapter 2 Using the Utility36
Omni.Net Lite User’s Guide
Note: The TA and the computer should use the same flow control protocol.

2.11 Analog Port: Local DN and Options
This section shows you how to assign the phone number(s) to voice calls and set port priority.
2.11.1 MSN (Multiple Subscriber Number) and Subaddress
Multiple Subscriber Number (MSN) is where the telephone company gives you more than one
number for your ISDN line. You can assign each number to a different port, e.g., the first
number to data calls, the second to A/B adapter 1 and so on. Or (DSS1) the telephone
company may give you only one number, but allow you to assign your own subaddresses to
different ports, e.g., subaddress 1 to data calls and 2 to A/B adapter 1.
2.11.1.1 Phone Number Assignment Example
Different telephone companies deploy different types of switches for ISDN service.
Depending on the switch for your particular installation, you will have a different number of
telephone numbers.
When your telephone company provides you with more than one phone number (say 5009001
and 5009002), you can connect two analog phones and/or G3 fax devices to the PHONE 1 and
PHONE 2 ports and assign each number to a port. If you attach one analog phone and one fax
machine to the analog ports but don’t assign any phone number to either port, both telephone
and fax ring when there is an incoming call. That will be difficult to tell whether it is a fax call
or voice call.
Follow the steps for the configuration method of your choice to assign the phone numbers.
After configuration, the TA will route a call to the port that matches the dialed number.

2 Enter the first number in the Address field beside Port 1 and the second number in the
Address field beside Port 2.
3 Click Submit to TA to save the changes back to the TA.
2.11.2 Caller ID
The caller ID (Caller Identification) information will display on the analog ports. Two caller
ID service types are supported by your TA.
2.11.2.1 Type 1: On-hook Caller ID Transmission
If the caller ID protocol uses DTMF (Dual Tone Multi-Frequency) signal, the caller ID
information includes the phone number and is sent prior to ringing.
If the caller ID protocol uses FSK (Frequency Shift Keying) signal, the phone number will be
sent during ringing.
The caller ID signaling type varies depending on the country.

and activated on your TA, the call waiting phone number is displayed when you are on the
phone.
Chapter 2 Using the Utility44
Omni.Net Lite User’s Guide
2.11.3 Dialing Method
There are two ways to send a message containing the phone number: EN-BLOC sending and
OVERLAP sending.
In En-Bloc mode, the complete phone number is sent in the first signaling message. Users
enter all digits of the phone number before a timeout period expires (the call times out if there
is inactivity for more than four seconds) or press “#” to indicate the complete phone number
has been entered.
OVERLAP sending is similar to what the traditional PSTN (Public-Switched Telephone
Network) telephone system uses. OVERLAP sending means sending some phone digits in
the first signaling message and the rest in subsequent signaling message. Users enter the phone
number after a dial tone. The ISDN network is aware of the completion of the phone number
automatically. You can not enter the sub-address when using overlap sending.
OVERLAP sending is usually used as the default for voice calls. For data calls, only ENBLOC sending is used.

2.12 Voice Calls
This section covers how to initiate and receive calls over an ISDN through the analog ports on
your ISDN TA and introduces supplementary services including call hold, call waiting, call
transfer and three-way conference.
Note: You can only use the utility, AT command or Tone command to activate or
deactivate call waiting. Use the flash key and the digit keys on the telephone to
invoke supplementary services (see Section 2.12.4 on page 47).
2.12.1 Placing a Voice Call
You can use your analog phone connected to the PHONE 1 and PHONE 2 ports to dial out a
call directly. With the Quick Dial feature, you can place an ISDN voice call by dialing “nn#”
(where nn=00-04, pre-stored phone number index). You must store up to five phone numbers
first by using the utility, AT commands or tone commands. Refer to Section 2.9 on page 40 on
how to store a phone number with the utility.
Chapter 2 Using the Utility46
Omni.Net Lite User’s Guide
2.12.2 Answering a Voice Call
To answer an incoming call, just pick the receiver when that telephone is ringing.
Voice calls are routed to one or both of the analog ports (PHONE 1 or/and PHONE 2) based
on the phone number assignment when they are received. When the same number is assigned
to both ports, you can choose the port you want to receive calls by setting the priority of the
ports. If two ports have same priority, both ports receive ring signals. See Section 2.11.4 on
page 45 on how to configure port priority.
When answering an incoming call, the TA will first be identified if the calling number matches
the MSN settings. The Multiple Subscriber Number (MSN) supplementary service enables
multiple ISDN numbers to be assigned to a single ISDN BRI line. It allows the caller to select,
via the public network, one or more distinct terminals from a variety of terminal choices. Since
the TA supports many different communication protocols and two analog adapters, each of
these ports can individually be assigned to a different ISDN number (see Section 2.11.1 on
page 43 for more information).
The following table shows incoming voice call scenarios.

2.12.4 Supplementary Services
Supplementary services such as call hold, call waiting, call transfer, … are generally available
from your telecommunications provider. The TA supports all of the following services:
47Chapter 2 Using the Utility
• Call Hold
• Call Waiting
• Call transfer
• Three-Way Conference
Note: To take full advantage of the supplementary voice services available though
the TA's phone ports, you will need to subscribe to the services from your local
telephone company.
2.12.4.1 The Flash Key
Flashing means to press the hook for a short period of time (a few hundred milliseconds)
before releasing it. On newer telephones, there should be a "flash" key (button) that generates
the signal electronically. If the flash key is not available, you can tap (press and immediately
release) the hook by hand to achieve the same effect. However, using the flash key is
preferred since the timing is much more precise. With manually tapping, if the duration is too
long, it may be interpreted as hanging up by the TA.
You can invoke all the supplementary services by using the flash key. Commands for
supplementary services are listed in the table below
Omni.Net Lite User’s Guide
After pressing the flash key, if you do not issue the sub-command before the default subcommand timeout (2 seconds) expires or issue an invalid sub-command, the current operation
will be aborted.

Press the flash key and then “1” to disconnect the current call and resume the hold call.
If you hang up the phone but a caller is still on hold, there will be a remind ring (see Section
4.1.1 on page 68 for more information).
2.12.4.3 Call Waiting
This allows you to place a call on hold while you answer another incoming call on the same
telephone (directory) number. By default call waiting is enabled on both telephone ports, but
can be disabled on either port.
If there is a second call to a telephone number, you will hear a call waiting tone. Take one of
the following actions.
• Reject the second call.
Press the flash key, wait for the sub command tone, press “0”.
• Disconnect the first call and answer the second call.
Either press the flash key, wait for the sub command tone and press “1”, or just hang up
the phone and then answer the phone after it rings.
• Put the first call on hold and answer the second call.
Press the flash key, wait for the sub command tone, press “2”.
2.12.4.3.1 Disabling Call Waiting
The call waiting tone will interfere with the data communication. It is highly recommended
that you disable the call waiting feature on the port to which a fax or modem is connected.
To disable call waiting on either port, select the Disable PORT 1/2 call waiting check box
in the Analog Port Supplementary Services screen of the utility.

Using AT Commands
3.1 AT Commands Overview
An AT Command is a command in asynchronous data format issued by the computer to the
ISDN TA through the asynchronous computer-modem interface. AT commands are used to
configure and control the TA by typing commands at a computer or terminal keyboard. To
send an AT Command from a computer to the TA, you must run a communication software
program and the TA must be in command state.
Commands must be written in a specific form in order for the TA to recognize them. A
command begins with the letters “AT” or “at”, followed by one or more printable characters
and then ended by pressing [ENTER], as shown in the following example.

Set the minimum threshold. The TA drops the second B-channel when traffic is
below the threshold.
AT%M5=nn= 1-255. The unit is 5-second. The default is 24, that is, 2 minutes.
Set the time interval between calculating traffic load.
Note: The high threshold must be greater than the low threshold, otherwise, both of
them will be reset to the defaults as shown in the table.
If you set %M2=1, %M3=0, %M4=0 and %M5=1, the BOD function will be disabled and the TA
establishes fixed multilink PPP data call with both two B-channels and release bandwidth for
voice calls.

Using Tone Commands
You can also use a telephone keypad to configure the TA using tone commands.
4.1 How to Use Tone Commands with a Telephone Keypad
1 Make sure your TA hardware is properly connected (refer to the Quick Start Guide).
2 Pick up the receiver of the telephone which is connected to the PHONE 1/2 port.
3 Issue the *** tone command by dialing the asterisk (*)key three times. You will then
hear a configuration tone (refer to Table 21 on page 68for more information).
4 You can now use the tone command(s) to configure the TA. If the command is valid, you
will hear a configuration confirmation tone. If the command is not valid, the TA rejects it
and generates a busy tone. Hang up the phone and repeat steps 2 and 3 to issue the
command(s) again.

Troubleshooting
This chapter covers potential problems and possible remedies. After each problem description,
some instructions are provided to help you to diagnose and to solve the problem. Please see
our included disk for further information.
Table 23 Troubleshooting
PROBLEMCORRECTIVE ACTION
None of the LEDs are
on.
I cannot connect to the
Internet.
Windows does not
auto-detect the RS232 connection to the
TA.
I need two B-channels
for Internet access, but
only one B-channel is
active.
The TA does not
release bandwidth for
incoming voice calls.
Make sure the TA's power adaptor is connected to the TA and an appropriate
power source. Check that the TA and the power source are both turned on.
Make sure your computer or terminal is turned on.
Check all cable connections.
Turn the TA off and on. If the error persists, you may have a hardware
problem. In this case, you should contact your local vendor
Click Start, Control Panel, double-click Phone and Modem Options (or
Modems). If Omni.Net Lite TA is not present, install the driver.
Make sure you entered the correct phone number, user name and password.
Make sure the ISDN port is properly connected to the ISDN wall jack with a
RJ-45 cable.
Connect a phone into the PHONE 1 or PHONE 2 port and see if you get a dial
tone.
Carefully follow the instructions to uninstall and reinstall the software driver.
Restart your computer
Make sure the TA is turned on and connected to a serial port on the computer.
Perform a hardware scan by clicking Start, Settings, Control Panel and
double-clicking Add/Remove Hardware. (Steps may vary depending on the
version of Windows). Follow the on-screen instructions to search for the
modem and install the driver.
Check for possible hardware conflicts. In Windows, click Start, Settings, Control Panel, System, Hardware and then click Device Manager. Verify
the status of the modem under Network Adapters. (Steps may vary
depending on your version of Windows).
Connect the TA to another computer. If the error persists, you may have a
hardware problem. In this case, you should contact your local vendor.
By default, the TA uses dynamic 128K MLP.
Use the utility to enable fixed MP to have the TA always transmit data at 128
Kbps or configure the minimum and maximum thresholds for adding or adding
the second B-channel according to traffic load (see Section 2.5 on page 32).
Make sure you have subscribed to the call waiting service first.
Check if the call bumping feature is activated.
