Heritage Series ADSL Bridge/ Router
A-13
Appendix
A list of networks maintained by each router on an internet.
Information in the routing table helps the router determine the next
router to forward packets to.
Serial port
A connector on the back of the workstation through which data flows
to and from a serial device.
Server
A device or system that has been specifically configured to provide a
service, usually to a group of clients.
SHDSL
G.SHDSL stands for Symmetric High Bit Rate Digital Subscriber Loop
and is defined by the new ITU Global Standard G991.2 from February
2001. It delivers voice and data services based on highly innovative
communication technologies and will thus be able to replace older
communication technologies such as T1, E1, HDSL, HDSL2, SDSL,
ISDN and IDSL in the future.
Subnet
A network address created by using a subnet mask to specify that a
number of bits in an internet address will be used as a subnet number
rather than a host address.
Subnet Address
An extension of the Internet 32-bit addressing scheme which allows
the separation of physical or logical networks within the single
network number. assigned to an organization. TCP/IP entities
outside this organization have no knowledge of the internal
‘subnetting’.
Subnet mask
A 32-bit number to specify which part of an internet address is the
network number, and which part is the host address. When written in
binary notation, each bit written as 1 corresponds to 1 bit of network
address information. One subnet mask applies to all IP devices on an
individual IP network.
RS-232
EIA standard specifying the physical layer interface used to connect a
device to communications media.
SNMP
Simple Network Management Protocol - A widely implemented
Internet network management protocol that allows status monitoring,
getting/setting of parameters for configuration and control of
network devices, such as routers and bridges.
