collection, performance, and security. Refer to: SGMP, SNMP2.
T1
A TDM physical transmission standard consisting of two twisted wire pairs and
related equipment capable of carrying a 1.544 Mbps DS-1 signal. Term often
used interchangeably with DS-1. Refer to: AMI, B8ZS, DS-1.
TCP/IP
Transmission Control Protocol/Internet Protocol, The protocol suit 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
