MAC
Short for Media Access Control address, a hardware address that
uniquely identifies each device of a network. The address is not pro-
grammable by the user and the manufacturer of the device must regis-
ter with IEEE before receiving an assigned group of addresses.
Network
Two or more computer systems connected together.
Packet
A piece of a message transmitted over a packet-switching network.
One of the key features of a packet is that it contains the destination
address in addition to the data.
Subnet
A portion of a network that shares a common address component. On
TCP/IP networks, subnets are defined as all devices whose IP addresses
have the same prefix. Dividing a network into subnets is useful for both
security and performance reasons.
Subnet Mask
A mask used to determine what subnet an IP address belongs to.
TCP
Abbreviation of Transport Control Protocol, and pronounced as sepa-
rate letters. TCP is one of the main protocols in TCP/IP networks.
Whereas the IP protocol deals only with packets, TCP enables two
devices to establish a connection and exchange data. TCP guarantees
delivery of data and also guarantees that packets will be delivered in
the same order in which they were sent.
WAN
A computer network that spans a relatively large geographical area.
Typically, a WAN consists of two or more local area networks (LANs).
Computers connected to a wide area network are often connected
through public networks, such as the telephone system. They can also
be connected through leased lines or satellites.

[020] System Status
If option [2] is on, the T-Link module will supervise communication with
the receiver. If option [2] is OFF , no trouble will be generated if commu-
nication is lost with the receiver. (Recommended OFF)
If option [3] is on, the T-Link module will supervise the communication
with the panel. If option [3] is OFF and communication is lost with the
trouble event will be transmitted from the T-Link to the
panel, no
receiver.
