Stands for Simple Network Management Protocol. This is a network management
protocol almost dedicated to TCP/IP networks. SNMP monitors and controls network
devices, and manages setup, collection of statistical data, operation performance, and
security features. Reference: SGMP and SNMP2
This is the facility of a digital WAN service provider. T1 uses the AMI or B8ZS coding
method to transfer DS-1 format data at a rate of 1.544Mbps over a phone switching
network. Compare to: E1; Reference: AMI, B8ZS, DS-1
Stands for Transmission Control Protocol/Internet Protocol. TCP/IP is a general name of
the protocol suites developed in the seventies by DoD of the U.S. to help build a global
inter-network. TCP and IP are two of the best known protocol suites. Reference: IP and
TCAP
Stands for Telephone Company. Telco refers to a telephone service provider. Typically,
Telco means individual local telephone service providers such as Bell, and sometimes
includes long distance telephone service providers.
This is a standard terminal emulation protocol included in the TCP/IP protocol stacks.
Telnet is used to connect remote terminals. Telnet allows you to log into a remote system
and to use the resources like they are connected to a local system. Telnet is defined in
RFC 854.
Stands for Virtual Channel Identifier. VCI refers to a 16-bit field in the header of an ATM
cell. VCI as well as VPI allows you to identify the next receiver of a cell while the cell is
being delivered to the receiver through a series of ATM switches. The ATM switches use
the VPI/VCI field to identify the next network VCI that the cell should pass to reach the
receiver, which is the final destination. The features of VCI are similar to those of DLCI.
Stands for Very-high-data-rate Digital Subscriber Line. VDSL is one of the four DSL
technologies. VDSL provides downstream of 13 Mbps to 52 Mbps and upstream of
1.5Mbps to 2.3Mbps through a pair of twisted copper wires. The operation range of
VDSL is limited to 1,000ft to 4,500ft (304.8m to 1,372m). Compare to: ADSL, HDSL,
and SDSL
Stands for Voice Over ATM. VoATM enables a router to deliver voice traffic (e.g. phone
calling or facsimile) over an ATM network. Voice traffic is encapsulated in a specific
AAL encapsulation method for multiplexed voice when voice traffic is sent in ATM.
Stands for Voice Over Frame Relay. VoFR enables a router to deliver voice traffic (e.g.
phone calling or facsimile) over a frame relay network. When voice traffic is sent
through frame relay, the voice traffic is encapsulated after being decomposed into
segments by using the FRF.12 encapsulation technique to pass the frame relay network.
