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.

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.
