Cat5e or Cat6
It is an ISDN Network Termination device. ...or... It is a rack used to house network devices.
Category 5. This is used to specify a quality of network cabling. Category 5 is the lowest category that is usable for network cabling.
The Integrated Services Digital Network (ISDN) uses Digital Subscriber Signalling System No. 1 (DSS1) protocol interfaces to connect subscribers to the network. These are User-to-Network (UNI) interfaces. Signalling System No. 7 (SS7) is a suite of signalling protocols used in Network-to-Network (NNI) interfaces. These are connections between network elements within the ISDN.
Integrated Services Digital Network (ISDN) is a digital, point-to-point network capable of transmitting speeds of about 2Mbps. A computer connects to an ISDN line via an ISDN adapter and uses the same type of wiring as a Telephone wire. The only difference is ISDN can carry analog (voice) and digital signals, so it can be used to connect to the internet. It can be connected by the phone company but it is rarely used as it needs special equipment and is more expensive than other way.
A SONET is a type of network technology layer that is physical. It is used for transporting a lot of traffic over fiber optic cabling.
it is not UPT ,it is UTP which stands Unshielded Twisted Pair. The UTP is mainly used for network cabling i.e; LAN cabling.
it is type of Internet connection in which a jack of telephone with twisted pair telephone cabling is used. it is used in making home network and also inexpensive. it is slow 56kpbs
carrying user voice and data circuit switching packet switching
An isdn stands for integrating services digital network ,it is a communication media througt which we can transmitte our voice,video and data, in isdn line two modem are used to for commnication one at source and other at the destination ,these modems are called isdn modem this is Qadar wafa from Kabul qadarwafa_4all@yahoo.com qadarwafa@multinet.af qadar-08@hotmail.com
To combine two wires that will look like one wire
Rj-45 is the most common type of cabling. RJ-45 refers to the terminator (connector) on the end of the cable, and the jack it plugs into--more specifically RJ-45M and RJ-45F, respectively. The associated cabling will be CAT(category)-5 or CAT-5e(enhanced), which are in the class of Unshielded Twisted Pair. A star network is typified by the hub or switch, with a cable running from it to every device on the network. Other cabling might be used, but CAT-5 is far and away most common.
