developed by DoD (USA) in 1970s for the worldwide inter-network

development. TCP & IP is the most well known protocols of the suite.

Refer to: IP, TCAP.

Telco

Telephone Company, referring to the company offering telephone

service to customers. Typically, it refers to an individual company such

as Bell operating company offering local telephone service, however,

sometimes local telephony service providers are included.

Telnet

Standard Terminal Emulation program covered by TCP/IP protocol

stack. Used for remote terminal connection. Via Telnet, users can log-

in to the system and operate the resources as working on the local

system. Defined on RFC 854.

VCI

the address or label of a VC; a value stored in a field in the ATM cell

header that identifies an individual virtual channel to which the cell

belongs. VCI values may be different for each data link hop of an ATM

virtual connection.

VDSL

New DSL technology that accepts bandwidths of up to 27 Mbps over

relatively short distances. VDSL, in the process of being standardized,

allows symmetric or asymmetric throughputs that are much higher than

other xDSL standards (up to 27 Mbps when downloading and 3 Mbps

when uploading under asymmetric or 14 Mbps in symmetric), as well as

the simultaneous transport of ISDN (Numeris) services but with much

shorter ranges that do not exceed 900 m to 1 km. In practice, this

technique may require the deployment of optical remotes and the

setting up of active equipment in the local loop. Compare with: ADSL,

HDSL, SDSL.

VoATM

Voice Over ATM. Voice over ATM enables an ATM switch to carry voice

traffic (for example, telephone calls and faxes) over an ATM network.

When sending voice traffic over ATM, the voice traffic is encapsulated

using AAL1/AAL2 ATM packets.

VoFR

Voice Over Frame Relay. Voice over Frame Relay enables a router to

carry voice traffic (for example, telephone calls and faxes) over a

Frame Relay network. When sending voice traffic over Frame Relay, the

voice traffic is segmented and encapsulated for transit across the

Frame Relay network using FRF.12 encapsulation.

VoHDLC

Voice Over HDLC. Voice over HDLC enables a router to carry live voice

traffic (for example, telephone calls and faxes) back-to-back to a

second router over a serial line.

VoIP

VoIP (Voice delivered using the Internet Protocol) is a term used in IP
