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, 4M or 10M.
For example if 64 is configured, there will be at least 64kbps reserved for VoIP. The
primary function of this setting is to reserve bandwidth for VoIP.

When set to "Yes", the HT503 acts as an UPnP gateway for your UPnP enabled
applications. UPnP = "Universal Plug and Play"
When set to "Yes", the HT503 responds to the PING command from other computers,
but is also made vulnerable to DOS attacks. Default is No.
When set to "Yes", the user can access the web configuration pages through the WAN
port, instead of through the PC port. Warning: this configuration is less secure than the
default option. Default is No.
This allows the user to change/set a specific MAC address on the WAN interface.
Note: Set in Hex format
Sets the LAN subnet mask. Default value is 255.255.255.0
Base IP for the LAN port, which functions as default gateway for its LAN. Default value
is 192.168.2.1
The length of time the IP address is assigned to the LAN clients. Value is set in units of
hours. Default value is 120 hrs (5 days).
This function forwards all WAN IP traffic to a specific IP address if no matching port is
used by HT503 or in the defined port forwarding.
Allows users to forward a matching (TCP/UDP) port to a specific LAN IP address with a
specific (TCP/UDP) port.
The code to access the PSTN line (Maximum 5 digits). Default is "*00". Any time user
can make PSTN calls from the analog phone connected to FXS port. By default, user
may pick up the phone, dial *00, and after obtaining PSTN line ( user will hear regular
dial tone) normal PSTN dialing is allowed.
PIN code to bridge from VoIP to PSTN (Maximum 8 digits, No Default)
PIN code to bridge from PSTN to VoIP (Maximum 8 digits, No Default)
If the dialed digits match one of the specified prefix here, outbound calls will be initiated
from PSTN line. This field is especially useful for emergency calls.
Calls are unconditionally forwarded to the specified PSTN phone number for all
incoming VoIP calls on FXO port.
Calls are unconditionally forwarded to the specified VoIP phone number for all
incoming PSTN calls. Each incoming call from the PSTN will first ring the analog phone
connected to FXS port. This call from the PSTN network will be forwarded to the
preconfigured VoIP extension if it is not answered. User can configure the number of
rings before forwarding calls to the VoIP extension. Configure number of rings using
the "number of rings" parameter located in the FXO Port Configuration page.
