Table 1-14 G-241W-A indoor ONT interfaces
G-241W-A indoor ONTs are single-residence ONTs that support Wireless (Wi-Fi)
service. Wi-Fi service on these ONTs are compliant with the IEEE 802.11 standard
and enabled or disabled using a radio on/off switch.
In addition to the Wi-Fi service, these ONTs transmit Ethernet packets to four RJ-45
Ethernet ports, and voice traffic to two RJ-11 POTS ports. These ONTs have two
USB ports also.
The ONTs also support RF video traffic on one F-type coaxial connector. The ONTs
feature fiber optic and power connectors.

I-240W-S I-241W-S I-241W-U Product Guide
Figure 1-5 G-241W-A ONT hardware block
ONT SoC technology consists of five key elements:
• GPON MAC
The Gigabit Passive Optical Network Media Access Control (GPON MAC)
element on the SoC terminates the GPON interface using an optical diplexer. This
interface supports GPON as described in G.984.3 (GPON TC Layer) ITU
specification.
• Ethernet MAC
The SoC provides up to four GE MACs.
• DSP interface
The Digital Signal Processor (DSP) provides voice processing for 2 POTS lines
with the 3-way calling. The DSP has a dedicated 64 kbyte instruction cache and
shares a 32 kbyte data cache with the Control Processor.
• Control Processor
The Control Processor features an integral memory management unit that
supports a dedicated 64 kbyte instruction cache and shares a single 32 kbyte data
cache with the DSP. The Control Processor and DSP also include a single channel
Data Management Application (DMA) controller with a 4 kbyte read ahead
low-latency Dynamic Random Access Memory (DRAM) access port. The
processors typically run at 400 MHz.
• Switch matrix
The Switch matrix provides an integrated data channel between the four GE
MACs, the GPON MAC, the DSP, the control processor, and the other integrated
elements such as flash memory, DRAM, and the local bus controller.
These ONTs can also interact with additional hardware components to support
functionality not provided by the SoC technology.

1.10 G-241W-A standards compliance
G-241W-A indoor ONTs are compliant with the following standards:
• 802.11b support for maximum transmit power (EIRP) equal to or greater than 200
mW (23.01 dBm)
• 802.11g support for maximum transmit power (EIRP) equal to or greater than 100
mW (20 dBm)
• 802.11n support for wireless LAN interface
• G.711a/u, G-729 CODEC
• G.984 support GPON interface (framing)
• G.984.2 support for Amd1, class B+
• G984.5 support for optical and other transport network infrastructures
• Wi-FI: WEP/WPA/WPA2, WPA-PSK/WPA2-PSK
1.11 G-241W-A special considerations
G-241W-A are package D ONTs.
G-241W-A indoor ONT considerations and limitations
Table 1-15 lists the considerations and limitations for Package D G-241W-A ONTs.
Table 1-15 G-241W-A ONT considerations and limitations
Upgrade considerations and limitations
Existing ONTs that use 7342 ISAM FTTU releases older than R04.06.xx and
R04.07.xx must be upgraded to use R04.00.10 software while assigned to a PON ID
value smaller than 64. For this purpose, if split ratios larger than 1:64 are being
deployed, you may choose to set aside the first PON ID as a staging point.
Considerations and limitations
The ONT pads packets to 104 as SoC limitation
Due to a Layer 3 packet processing limitation, the ONT can handle up to 220Mb/s (@ up to 72 bytes
for Ethernet Frame sizes. Rates that exceed 220Mb/s with Ethernet frame sizes of less than 72 bytes
will result in dropped frames at the ONT.
The uplink port of the SoC chipset is limited to 1 Gb/s
Some parameters are system level, not line level; for example, enable_caller_id, digitmap.
Most parameters can be configured in either OMCIv2 or XML.The OMCIv2 configuration values
generally take precedence over the XML ones.
Specifically, when voice parameters are configured using OMCIv2, attempting to overwrite the
configuration using XML will have no effect.
The release timer, rls-timer, needs to be configured in OMCIv2, because when it is not, the default
OLT value will be applied, not the XML value.

2.6 Procedure
Use this procedure to install a G-241W-A indoor ONT.
1 Place the indoor ONT unit:
a On the flat surface, such as a desk.
i Wrap the excess optic cable inside the fiber storage tray.
ii Attach the fiber storage tray to the ONT.
iii Place the ONT on the flat surface, horizontally resting on its four feet.
b On a wall.
i Determine whether to mount the G-241W-A indoor ONT in either the
vertical or horizontal position. If possible, mount the ONT on a wall
stud.
ii Mark the wall with the location of the mounting holes shown in
Figures 2-1 and 2-2. These holes should be the same distance apart as
the distance between the centers of the keyholes on the ONT. Use the
one of the two available fiber storage trays as a wall mounting template
to indicate the location of the mounting holes on the wall.

iii Attach the fiber storage tray to the wall by drilling the holes in the wall
where the tray will be mounted and then drive the mounting screws into
the holes.
Do not drive the mounting screws into the wall completely. Leave
approximately 1/8 in. (6 mm) between the screw head and the wall
surface.
iv Wrap the optic cable around the spools in the fiber storage tray.
v Attach the fiber storage tray to the wall by placing the screw heads of
the mounting screws into the wall mounting holes, either vertical or
horizontal, on the tray.
vi Slide the ONT enclosure over the fiber storage tray at a forty-five
degree angle and seat the ONT securely on the tray.
Aligning features molded into the fiber storage tray and ONT enclosure
interlock allowing the ONT to seat on the tray.
2 Review the connection locations as shown in Figures 2-3 and 2-4.

6 Connect the SC/APC fiber optic cable directly to the ONT. See Figure 2-3 for
location of the fiber optic c onnector.
7 Install the power supply according to manufacturer specifications.
8 Con nect the power cable with an 8-pin Molex connector to the power supply.
9 Con nect the power cable with an 8-pin Molex connector to the ONT unit; see
Figure 2-5 for the Molex pin alignment.
Note 1 — Observe the following:
• To comply with FCC standards, use either RG-6 or RG-59 coaxial
cable. Also, proper attenuation must be inserted at the coaxial
output to guarantee that at the end of any coaxial drop, every video
signal is below 15.5 dBmV and audio signals are below 2.55 dBmV
(per channel).
• You may need to install the 75-ohm coaxial F connector on the video
cable.
Note 2 — Observe the following when connecting the F-type coaxial
connector to the coaxial connector on the ONT:
• Fully tighten the F-type connector on the cable by hand before using
a wrench to complete tightening (up to a maximum of an additional
1/8 turn). If using a torque wrench (as is recommended) to tighten
the connector, the torque setting should be between a minimum of
20 in-lbs and a maximum of 40 in-lbs. The connector should be tight
enough when the task is complete that it can not be unscrewed by
hand.
Danger — Fiber cables transmit invisible laser light. To avoid eye
damage or blindness, never look directly into fibers, connectors, or
adapters.
Warning — Be careful to maintain a bend radius of no less than 1.5 in.
(3.8 cm) when connecting the fiber optic cable. Too small of a bend
radius in the cable can result in damage to the optic fiber.
Note — Fiber cable preparation varies depending on the type and size
of the inside or outside plant fiber cable being spliced to the SC/APC
fiber optic pigtail cable.
Warning — To avoid the possibility of damage to the pins on the power
cable connector, carefully align the pins on the connector on the cable
with the pin holes in the power connector on the ONT before making the
connection.
