1.1 General Concept

The Universal Communication Hub UCH-100 comes with two ports, Serial (DB9) and Modem
(RJ11). It simply provides telephony interface to data/fax devices over digital network.

Equipment such as fax machine, credit card terminal, security alarm, data modem, which all uses
RJ11 interface and requires fixed line telephony network, UCH-100 offers an alternative
mechanism to utilize these devices in environment where fixed line telephony network is not
readily available.

2 Application

2.1 Fax

3 Store and Forward Fax

Store and forward fax means the fax is stored and relayed over data network. This mechanism is
typically preferred when

a. The network bandwidth does not support fax protocol/encoding
b. The network connectivity is not consistent/reliable. If a fax has to be sent

multiple times before it can be successfully delivered, then Store and forward is
the more economical method.

To enable the data capability, turn on the unit by pushing the switch to FAX.

3.1.1.1 Notification

The first step of configuration of store-and-forward faxing is to determine what type of notification
is to be used.

Notification is used for two purposes:

c. Indicating the delivery status (Mobile Originated Fax)
d. Indicating the availability of incoming fax (Mobile Terminated Fax)

Several notification mechanisms are supports:

1. GSM style SMS: the SMS message length should be able to support 100+
characters. The Gateway will send the entire status message in the SMS.

2. Short SMS: for network with shorter SMS message length capability, this
mechanism is used to simply “wake up” the Universal Communication Hub and
the Universal Communication Hub will attempt to establish a data call to the
Gateway to pick up the status

3. Direct Call: For system that does not support SMS, this mechanism is used for
the Gateway to place a short data call to wake up the Universal Communication
Hub

The appropriate notification mechanism needs to be provisioned at the central Gateway Business
Management System interface to allow proper operation.

3.1.1.2 Mobile Originated Fax

Mobile Originated fax allows an off-the-shelf G3 fax machine to be used to send documents over
the data network. After connecting the G3 fax machine to the RJ11 modem port, wait for the LED
#2 to be ON (indicating modem port is ready), then take the fax offhook, and dial the number in

the format: COUNTRY_CODE + NUMBER. Do not dial any prefix like 00 or 011, the system will
handle that automatically.

3.1.1.3 Mobile Terminated Fax

Mobile terminated fax is automatic. When the user subscribes to a service plan, a “MAILBOX”
number will be assigned to the unit. When a fax is sent to that MAILBOX number (this number is
not the same as the mobile data number), a notification is sent to the unit and the unit will connect
to the Gateway to pick up that message. When the message is completely downloaded to the
unit, it will simply RING the fax machine and print the message out.

If for some reason the fax is not powered on, out of paper or simply not connected, the user has
to use the Message Management to get the fax to be printed. (see LOCAL COMMAND ##4).

3.2 Data

To enable the data capability, turn on the unit by pushing the switch to DATA.
Once in data mode, a data modem can be connected to the modem port. The user must dial the

EXACT same number that the call is to be established, including the prefixes. The Universal
Communication Hub will establish a data call based on that number.

4 Configuration and Status

The functionality of the UCH-100 is dictated by TWO settings, the SLIDE SWITCH setting and the
DIP switch setting. The SLIDE switch setting position determines whether UCH-100 will be
operating in DATA or FAX mode; this switch can be accessed easily. The DIP switch is not
exposed externally and should normally be set by the Service Provider only. The DIP switch
position will dictate the personality of the UCH-100.

4.1 LED indication

The UCH-100 has 6 LEDs that indicate the operational status of the unit. The LEDs status are:

4.2 LOCAL commands

Though the UCH-100 has no built-in keypad, the user can still command UCH-100 to perform
certain tasks or retrieve internal status and report. This command is performed through a tone­based telephony device (such as a phone or fax machine). To enter the command, simply take
the attached telephony device off hook, enter the key sequence and then hang up.

All the commands start with two “#” keys. The following is the supported commands. The only
command user needs to remember is “###”.

KEY

4.4 SERIAL CONFIGURATION UTILITY

In some cases, where preloaded configuration templates do not provide sufficient flexibility, UCH­100 offers EXPERT users a way to enter/modify more specific configuration parameters via the
SERIAL port.

There are TWO user definable configuration templates, one is when the power switch is set to
FAX mode and one is when power switch is set to DATA mode. To enter the configuration mode,
all the DIP switches should be turn to ON. Depending on the position of the power switch, the
corresponding configuration template will be used. To activate the user defined configuration
template after the change, simply turn OFF the unit, toggle the DIP switch position from ON to
OFF and then turn back on the unit.

To connect the computer/terminal to the SERIAL PORT, a NULL MODEM and a GENDER
CHANGER must be used, as both end of the connection are in DTE mode. The setting on the
computer/terminal end should be 38400 bps, 8 bit, no parity, no hardware/software flow control.

The users must be familiar with UCH-300 configuration structure. UCH-300 comes with a 16-key
keypad. The command input mapped to the keys are:

UCH-300 keypad UCH-100 command input
0 – 9, *, # 0 – 9, *, #
CONFIG/SELECT M
NEXT >
PREVIOUS <
CANCEL C

In addition, two other commands are available:

Write out configuraiton W
Quit Q

A typical configuration session includes the following steps:

1. TURN OFF the unit

2. SWITCH all DIP switch position to ON.

3. Connect a computer to the SERIAL PORT with NULL modem and GENDER changer in
between.

4. TURN ON the unit

5. Select a known template as the baseline by choosing a factory supplied configuration
template as the baseline.

6. Make modifications

7. Use ‘W’ command to write out the configuration in the FLASH. This may take a few
minutes.

8. TURN OFF the unit.

9. TOGGLE DIP switch POSITION 1 to OFF position

10. TURN BACK ON the unit.

Since the configuration can drastically change the behavior of the unit, we do not recommend
using this feature.

4.5 SOFTWARE UPDATE facility

In some cases, where software needs to be updated, UCH-100 provides a field update capability.
This capability is only available from APPLICATION software version 1.6.x. This should only be
performed by qualified technical staff, otherwise it could cause irreversible damage to the
software and can only be repaired by the manufacturer.

In order to activate this, first valid software needs to be obtained. This filed needs to be stored on
a computer with XMODEM capability. Then the following instructions need to be followed
carefully:

a. Power up the UCH-100 and connect a phone/fax machine to RJ11 connector
b. Connect UCH-100 to the computer with the file via a CROSS-OVER (NULL

MODEM) cable

c. The computer needs to set the port to 115,200 baud rate, 8 bit, no parity and

hardware (RTS/CTS) flow control

d. Take the phone/fax machine offhook, enter ##9*PIN* then hangup (PIN is

provided only to qualified service provider technical staff)

e. The computer connected to UCH-100 over CROSS OVER serial cable should

display instruction:

f. Select appropriate file to download and then activate XMODEM process (for

example, from HYPERTERMINAL, select TRANSFER->SEND FILE and enter
appropriate file name and choose XMODEM protocol).

g. After successful downloading the file, answer Y or y to start programming the

software to FLASH memory chip
h. Repeat this process for various files
i. When completing all the files, power cycle UCH-100 to activate the new software.

Example of how to update OPERATING SYSTEM: (as viewed on HYPERTERMINAL connecting
to UCH-100 SERIAL PORT)

Bye...

At this time, it is necessary to restart the system for new software to take effect. It is very
important to make sure software is loaded properly… otherwise, the system will not come
back up again.
