RS-232 —
EIA standard specifying the physical layer interface used to connect a device to
communications media.
Serialization Frames —
Frames sent out by servers under IPX to check whether illegal copies of
NetWare are in use on the network.
Service Advertising Protocol —
Protocol used in IPX for broadcasting information about
services available on the network, such as file servers, CD-ROM drives and modem pools.
SNMP —
Simple Network Management Protocol. A widely implemented Internet network
management protocol that allows status monitoring, getting/setting of parameters for configuration

Split B Channels —
Each 64 Kbps ISDN B-channel can be used individually for a separate data
connection.
Spoofing —
Spoofing is a technique used to remove poll and update service frames from WAN
links while ensuring that the network continues to operate normally. Spoofing is employed to
minimize dial-up line connection time.

TCP/IP —
Transmission Control Protocol/Internet Protocol. Refers to a set of internetworking
protocols developed by the U.S. Department of Defense that define a two level layered approach
for interoperability. TCP provides a connection-oriented Transport layer ensuring end-to-end
reliability in data transmission. IP provides for Network layer connectivity using connectionless
datagrams.

Telco Cloud —
The “cloud” of switched virtual connections over a Wide Area Network (WAN).
TELNET —
Internet standard protocol for remote terminal emulation that allows a user to
remotely log in to another device and appear as if directly connected.
TFTP —
Trivial File Transfer Protocol. A simplified version of the File Transfer Protocol (FTP)
allowing for file transfer between computers over a network.
