ring type
A feature that allows you to select one of four distinctive rings for your telephone. See
also distinctive ring. This feature is set under User Preferences, but can be changed at a
telephone. (Services, Telephony Services, System DNs)
ring volume
A feature that allows you to set the volume at which your telephone rings. This is a
telephone feature and has no system setting.
RIP
Routing Information Protocol (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 network convergence. RIP uses a
hop count as a way to determine 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.
The major alternative to RIP is the Open Shortest Path First Protocol (OSPF).
Release 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 Business
Communications Manager base unit needs to operate. The instructions stored in ROM
cannot be changed and are used by the Business Communications Manager base unit 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 origin to its destination on a network or the Internet.
Configure telephony routing under Call Routing. (Services, Telephony Services).
Configure intranet/internet routing under the Data headings).
