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.

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.
