MAC Address Clone (SPA122 Only)
A MAC address is a 12-digit code assigned to a unique piece of hardware for identification
purposes. Some ISPs require that you register a MAC address in order to access the Internet. If
you previously registered your account with another MAC address, it may be convenient to
assign that MAC address to your ATA. You can use the Network Setup > Advanced Settings
> MAC Address Clone page to assign a MAC address that you previously registered with your
Service Provider.

Field Description
Flow Control Flow control is a mechanism that temporarily stops the
transmission of data on a port. For example, a situation might
arise where a sending station (computer) is transmitting data
faster than some other part of the network (including the
receiving station) can accept. The overwhelmed network
element will halt the transmission of the sender for a specified
period of time.

can result if you choose a setting that is not appropriate for the
network devices.
