T1 o DS1 LOOP :
Dedicated circuit used to connect two points. It has 24 channels and uses for installations four
copper wires or two copper pairs. Each channel has 64K for a total of 1.544kbps.
T1 Ch (Channeled) :
Service that allows the simultaneous transmission and reception of 24 voice and data channels
(1.544 mbps) over a physical medium.
T1 (point to point) :
Consists in linking at least two locations through a T1 connection.
T1 for Internet :
T1 used for connecting to the Internet. Generally requires an Internet port.
ISDN (Integrated Services Digital Network) :
BRI: Consists of two channels that transport the client's information in the form of voice or data.
PRI: Consists of 24 channels that transport the information in the form of voice or data.
DIGITALIZATION :
An analog number is converted to digital substituting a DID
FRAME RELAY :
Network designed for the transmission of voice and data at high speed, allows for the interconnection
of local area networks geographically separated at a lower cost.
DSL (Digital Suscriber Line) :
Broadband service that permits the simultaneous use of Internet, fax and voice.
HDSL (High bit rate Digital Subscriber Line) :
The main characteristic of HDSL is that it is symmetrical: an equal amount of bandwidth is available
in both directions. HDSL can carry as much on a single wire of twisted-pair cable as can be carried
on a T1 line (up to 1.544 Mbps)
IP ADDRESS :
Number that identifies specific equipment inside a network that uses the TCP/IP protocol.
For example: 172.16.4.32.
Voice Over IP (VOIP) :
Protocol that converts voice signals into data packages using the Internet as a transport medium.
IP CENTREX :
Service that emulates the functions of a PBX. Also known as "hosted PBX" or IP Centrex. Requires
the use of SIP phones, switchboard and router.
IAD (Integrated Access Device) :
Equipment installed in the clients facilities to provide voice and data service. Converts digital
numbers into analog.
Multi Protocol Label Switching (MPLS) :
A type of network that allows managing in a more efficient way traffic and applications. With the
convergence of voice, data and video applications, businesses require the capacity to managing traffic
in their networks in a more effective way. MPLS networks offers a Class of Service or Quality of Service
(QoS) (CoS) option which permits the network administrator to specify traffic priorities and connect
multiple locations. WorldNet’s network is MPLS
EFM (Ethernet over the First Mile) :
Allows the connection of various copper circuits to increase Ethernet bandwidth.
POTS (Plain Old Telephone Service) :
Analog line that uses an electrical signal.
• BMS- (Business Main Station) Telephone single line for business, it's installed up to the jack.
It can be used for fax, ATH, DSL, dial-up and telephone. Use one voice channel to make or
receive calls.
• BML- (Business Main Line) Line used for switchboards and it's installed up to the HC. It has
two copper pairs and physically is a BMS, what makes it different is the programming.
• Trunks - is a line or link designed to handle many signals simultaneously, and that connects
major switching centers or nodes in a communications system. The transmitted data can be
voice (as in the conventional telephone system) data, computer programs, images, video or
control signals.
PBX (Private Branch Exchange) : Equipment that makes connections among the internal telephones of a private organization -
usually a business. It's commonly known as a switchboard.
