ring volume

A feature that allows you to set the volume at which your telephone rings.

ringing service

A Services section that allows you to make additional telephones ring at specified

times of the day and on specified days.

RIP

See Routing Information Protocol.

Rls button

Ends a call in the same way that hanging up the receiver does.

ROM (Read Only Memory)

Memory that stores data permanently. ROM contains instructions that the

Enterprise Edge Server needs to operate. The instructions stored in ROM cannot be

changed and are used by the Enterprise Edge Server each time it is turned on or

restarted.

Router

A router is a device that forwards traffic between networks, based on network layer

information and routing tables. A router decides which path network traffic follows

using routing protocols to gain information about the network and algorithms to

choose the best route based on a routing matrix.

Routing

The path a message takes from its point of origin to its destination on a network or

the Internet.

Routing Information Protocol (RIP)

RIP enables routers in the same autonomous system to exchange routing

information by means of periodic updates. RIP is a widely-used protocol for

managing routing information within a self-contained network such as a corporate

local area network (LAN) or an interconnected group of such LANs.

Using RIP, a gateway host (with a router) sends its entire routing table (which lists

all the other hosts is has on record) to its closest neighbor host every 30 seconds.

The neighbor host passes the information to its next neighbor and so on until all

hosts within the network have the same routing path information, a state known as

networkconvergence. RIPuses a hop count as a way todetermine network distance.

Each host with a router in the network uses the routing table information to

determine the next host to route a packet to for a specified destination.

RIP is considered an effective solution for small homogeneous networks. For

larger, more complicated networks, RIP's transmission of the entire routing table

every 30 seconds may put a heavy amount of extra traffic in the network.
