Time Zone Selects time zone to define date/time on the device.
Self-Defined Time Zone Allows users to define their own time zone.
Obtains time zone setting (offset) from a DHCP server using DHCP Option 2; it will override
selected time zone. If set to "No", the analogue adapter will use selected time zone even if

provided by DHCP server.
The Default setting is Yes.
Configures the languages of the voice prompt and web interface, except Spanish that it is only

in IVR. Available languages: English, Chinese, Traditional Chinese, Russian, Spanish IVR.
NAT/DHCP Server Information & Configuration
Controls whether the device is working in NAT router mode or Bridge mode. Save the setting
Device Mode
and reboot prior to configuring the HT812/HT814.
Defines the number of ports that can be managed while in NAT router mode.
NAT maximum ports
Range: 0 – 4096, default is 1024. Typically, one port per connection.
NAT TCP idle timeout in seconds. Connection will be closed after preconfigured, timeout if
NAT TCP timeout
not refreshed. Range: 0 – 3600
NAT TCP idle timeout in seconds. Connection will be closed after preconfigured, timeout if
NAT UDP timeout
not refreshed. Range: 0 – 3600, default is 300
Specifies the maximum uplink bandwidth permitted by the device. This function is disabled by
default. The total bandwidth can be set as: 128K, 256K, 512K, 1M, 2M, 3M, 4M, 5M, 10M or
15M.
Uplink bandwidth The primary function of this setting is to limit the uplink bandwidth for the device internal
system, signaling and NATed traffic. Example: When 512k is configured, there will be at least
512kbps limited for internal system, signaling and NATed traffic. Voice or RTP stream will
never be limited.
Specifies the maximum downlink bandwidth permitted by the device. This function is disabled
by default. The total bandwidth can be set as: 128K, 256K, 512K, 1M, 2M, 3M, 4M, 5M, 10M
or 15M.
Downlink bandwidth The primary function of this setting is to limit the download bandwidth for the device internal
system, signaling and NATed traffic. Example: if 128 is configured, there will be at least
128kbps limited for internal system, signaling and NATed traffic. Voice or RTP stream will
never be limited.
When set to "Yes", the HT812/HT814 acts as an UPnP gateway for your UPnP enabled
Enable UPnP support
applications. UPnP = "Universal Plug and Play"
Default is No. When set to "Yes", the HT812/HT814 responds to the PING command from
Reply to ICMP on WAN port
other computers, but is also made vulnerable to DOS attacks.
This allows the user to change/set a specific MAC address on the WAN interface.
Cloned WAN MAC Addr
Note: Set in Hex format
Allows users to configure the customized VLAN tag and priority value under switch mode.
LAN Port VLAN Feature Under
VLAN Tag range is 0-4094, the Priority Vlaue range is 0-7.
Bridge Mode
The Default for both is 0
When set to "Yes", device will function as a simple router and LAN port will provide IP
Enable LAN DHCP addresses to internal network. Connect the WAN port to ADSL/Cable modem or any other
equipment that provides access to public Internet
Base IP Address for a LAN port. Default factory setting is 192.168.2.1. Note: When the device
detects WAN IP is conflicting with LAN IP, the LAN base IP address will be changed based
LAN DHCP Base IP on the network mask — the effective subnet will be increased by 1.
For example; 192.168.2.1 will be changed to 192.168.3.1 if net mask is 255.255.255.0. Then
the device will reboot
Default value is 100. The last segment of IP address assigned to the HT812/HT814 in the LAN
Network.
LAN DHCP Start IP
Default configuration assigns IP address (to local network devices) starting from
192.168.2.100.
Default value is 199. This parameter allows a user to limit the number of local network
devices connected to the internal router.
LAN DHCP End IP
Default configuration assigns IP address (to devices connected to the LAN port) in a range
from 192.168.2.100 up to 192.168.2.199.
LAN Subnet Mask Sets the LAN subnet mask. Default value is 255.255.255.0
