PRODUCT INTRODUCTION
1. Product Introduction
The TranScend is a modular chassis (1RU platform) that uses plug-in modules which can elegantly simplify the return path
transport when used in conjunction with the I-HUB platform. This platform supports a variety of advanced products from ATX
to revolutionize the CATV optical access industry. This product is available in either AC or redundant DC (-48V) powering. It
can accommodate up to four plug-in modules. Currently available modules include:
1. High Sensitivity Quad Receiver for RFoG return path with the capability for built-in express ports.
2. Standard Sensitivity Quad Receiver for RFoG applications.
3. Frequency Stacker for upstream aggregation of four streams of 5-42 MHz.
4. Frequency Destacker to convert the four streams back to 5-42 MHz.
5. RFoG EDFA providing up to four ports at 18 dBm with or without express port capability.
6. Optical Switch for path redundancy.
The chassis provides extremely high density and with the express ports built-in, the amount of  ber interconnectivity is
greatly reduced. The chassis supports hot-swapping of the modules. A high level of integration in the modules makes the
modules very compact, thereby reducing the power requirements and minimizing heat dissipation. The chassis has a local
RS232 port, a RJ45 for remote Ethernet communication with the unit and an alarm contact port. The LCD display in the front
panel helps the operator to monitor all the modules plugged into the chassis.
The front and rear views of the chassis show the various ports available on TranScend chassis.

PRODUCT INSTALLATION
3. Product Installation
3.1 Unpacking & Inspecting a New Unit
Before shipment, ATX inspects and packs all the essential items carefully. Nevertheless, damage may occur during
shipment. The carrier assumes full responsibility for a safe delivery of the equipment.
1. Inspect the package for any physical damage.
2. Open the package.
3. Remove any packing material.
4. Inspect the unit for any physical damage.
5. Shake the unit with care, paying attention to any rattling loose parts that may suggest a concealed damage (some
noise due to moving cables is normal).
6. Check for any missing accessories.
When any damage is noticed to the merchandise, please notify customer service (see Service & Support section) and le a
claim with the carrier as noted below.
3.2 What To Do About Physical Damage
Record any evidence of physical damage or loss on the freight bill or receipt and have the carrier’s agent sign it. If you fail
to do so, the carrier may refuse to honor the damage claim. The carrier will supply you with any forms required to le such a
claim.
3.3 What To Do About Concealed Damage
Damage which is not apparent until the unit has been unpacked is termed concealed damage. The contents may have been
damaged due to rough handling even if there is no external evidence. If you should notice damage upon unpacking the unit
you should make a written request for inspection by the carrier’s agent within 10 days of the delivery date. Afterwards le a
claim with the carrier.
3.4 How To Return Equipment
Call customer service (see Service & Support section) for a Return Materials Authorization (RMA) number. You will need the
unit’s serial number, description of the problem, and some shipping information. We must receive the unit within thirty (30)
days from the date a RMA number is issued. If for any reason, you want to ship the unit 30 days after the RMA number has
been issued, you must obtain a new RMA number by calling customer service. Units received without an RMA number or
one with an expired RMA number will not be accepted by our receiving department.
3.5 Installation of the Equipment
Installation of the TranScend chassis is a multi-step process.
Step 1: Install the chassis to the rack with the mounting ears and the screws provided in the package, if they are not
pre-installed.
Step 2: Using the ground lug on the back of the unit, ground the chassis to the rack.
Step 3: (Optional) If you want to monitor the unit using SNMP, connect the LAN cable to the LAN port in the back for
remote monitoring. See section 8.3 for further details about remote management of the unit.
Step 4: (Optional) Connect the alarm cable to the DB9 connector in the back, if you want to monitor the unit using relay
contacts.
Step 5: (AC Unit): Connect the AC power cord from the unit to receptacle of the proper rating after making sure that the
power switch is in OFF position OR, FOR DC UNITS: attach terminal lugs with wires of the proper gauge to the
-48 DC feeds (A and B) in the rear of the chassis, ensuring proper color coding or polarity. Ideally, A and B
feeds should be from independent power sources for redundancy. Connect the other end of the DC wires to the
fuse panel after ensuring that the fuses are pulled. Reversing the polarity will not harm the unit over the

short term, but is to be avoided if possible. Each TranScend chassis unit will draw anywhere from
0.5 Amps to 2.0 Amps (maximum) at -48 Volts, depending on the number of modules plugged, the ambient
temperature, the airow conguration etc. Please ensure that the fuse panel is rated at 3A absolute
minimum for safe operation of the units.
Step 6: Turn the chassis on either by using the switch in the rear of the AC chassis or by plugging in the fuses of
appropriate rating in the case of DC units.
Step 7: (Optional) Using the local console port, set-up the IP address for the unit(s) to be monitored from remote location.
The unit(s) is now set-up to go live.
Step 8: Plug in the required modules from the rear. The chassis is shipped with the blank panels in place. Remove the
blank panel only in the slots where the modules are planned to be plugged. Leave the other panels in place to
ensure efcient air ow in the chassis.
Step 9: Connect the optical ber to the optical port in the rear of the chassis according to the design of the network.
Connect the RF cables as needed by the modules.

OPERATION OF THE TRANSCEND CHASSIS
4. Operation of the TranScend Chassis
A detailed procedure for operating the TranScend chassis and various plug-in modules is described in this section. The
menu operation of the plug-in modules is also described in this section. These modules include:
1. High Sensitivity Quad Receiver
2. Standard Sensitivity Quad Receiver
3. Return Stacker
4. Return Destacker
5. RFoG EDFA
6. Optical Switch
There are nine front panel LEDs, one indicates the chassis power supply status and four sets of two each indicate the status
of the four plug-in units. The number labeled on the front panel corresponds to the slot identication; 1 on the most left and 4
on the most right (closest to power switch) when facing the rear of the chassis.
4.1 LED Color Codes
There are four possible colors of LEDs. They are observed during the following conditions.
Off: Indicates the monitored function is unavailable. This is also observed temporarily during power on LED test.
Example #1: Only slot 1 and slot 2 have plug-in units. The LEDs for slot 3 and slot 4 are off.
Example #2: The High Sensitivity Quad Return Receiver is detected in slot 1; the RF LED for slot 1 is turned off since
RF detection is not available in this unit.
Green: Indicates the monitored function is healthy. This is also temporarily observed during power on LED test.
Example #1: The High Sensitivity Quad Return Receiver is detected in slot 1, and the OPT LED for slot 1 is green which
indicates the monitored level of all four optical power receivers in slot 1 are within normal operating range.
Amber: Indicates the monitored function is in minor alarm condition. This is also temporarily observed during power on LED
test.
Example #1: The High Sensitivity Quad Return Receiver is detected in slot 1, and the OPT LED for slot 1 is amber
which indicates the level of any one or more of the four optical powers received in slot 1 are in minor alarm range. The
minor alarm is triggered if the monitored level is between the high and high-high or low and low-low thresholds.
Red: Indicates the monitored function is in major alarm condition. This is also observed temporarily during power on LED
test.
Example #1: The High Sensitivity Quad Return Receiver is detected in slot 1, and the OPT LED for slot 1 is red which
indicates the level of any of the four optical powers received in slot 1 are within major alarm range. The major alarm is
triggered if the monitored level is beyond the high-high or low-low thresholds.

PUSHBUTTON OPERATIONS
5. Pushbutton Operations
There are  ve pushbuttons located at the front panel of chassis. They are designated as “Up” with an upper arrow indicator,
“Right” with a right arrow indicator, “Left” with a left arrow indicator, “Down” with a down arrow indicator and “Select” as the
center button.
5.1 Philosophy of Button Operations
5.1.1 Individual Button Operations
Up: The cursor moves up one line.
Down: The cursor moves down one line.
Right: Cycle through the available options for the line where cursor is located.
If the menu is for read-only attribute, the display shows the next available interface.
Example #1: If the current display is “#1 Optical Power”, then pressing the right button will display the “#2 Optical
Power”.
Example #2: If the menu is for the quantitative write attributes, the “Right” button increases the value.
When in the “Gain Setting Menu”, the cursor displays Gain (steps): 1, then pressing the right button increments the gain
steps and hence Gain (steps): 2 shall be displayed after the operation.
Left: Cycle through the available options for the line where cursor is located.
If the menu is for read-only attribute, the display shows the next available interface.
Example #1: If the current display is “#2 Optical Power”, then pressing the left button will display “#1 Optical Power”.
Example #2: If the menu is for the quantitative write attributes, then left button press operation decreases the value.
When in the “Gain Setting Menu”, the cursor displays Gain (steps): 3, then pressing the left button will decrease the
gain steps and hence Gain (steps): 2 shall be displayed after the operation.
Select: There are multiple meanings to the select button.
1. Select to execute the action where the cursor is located.
Example #1: If the cursor is located at the “Prev menu” line, the display shall change to the NEXT higher menu
after the “Select” button is pressed once.
2. Select to commit the option.
Example #1: In the “Gain Setting Menu”, if the cursor is located on the “Sel Ch: 1” line, the channel #1 shall be
used for gain adjustment after “Select” button is pressed.
NOTE: Only after pressing the Select button, the gain settings option is operated on the selected
channel.

3. Select to commit the setting to NVRAM.
Example #1: In the “Gain Setting Menu”, if cursor is on “Save: No (17)”, user must toggle the right or left button
to change the option to “Yes”. Then press “Select” to commit the value, 17, in the bracket into the NVRAM.
NOTE: Only if the value is committed into NVRAM, the chassis will use the selected gain level next
time the chassis recovers from power cycle .
5.1.2 Combination Button Operations
The combination button operations are unique to TranScend chassis. Each combination operation is de ned strictly for their
speci c usage as the following de nition.
Up+Down: When pressing and holding the Up+Down button simultaneously when traversing the slot menu, the front panel
displays current slot number. The front panel display will restore back to the previous display once the button combination is
released.
Example #1: User is within the “Status Menu” of slot #1, press and hold the Up and Down buttons, the front panel
displays “Current Slot: 1”. The “Status Menu” returns after releasing the Up and Down button combinations.

6.2 High Sensitivity Quad Receiver
6.2.1 Overview
The High Sensitivity Quad Receiver is a TranScend plug-in meant to receive return path signals in the 5-85 MHz frequency
range in RFoG networks. In these networks, the return path signal from the home ONU (Optical Network Unit) traverses an
optical splitter (typically a 1x32 or a cascade of 1x4 and 1x8 splitters) in the reverse direction. The wavelength of the return
path signal is typically 1610nm. In units that have an express port built-in, the receiver will work only in the 1610nm window
(1610 +/- 8 nm); in other units the return path wavelength has a relatively minor impact on the receiver performance through
changes in the responsivity of the photodiode.
