How would you terminate a T1 line?
Usually T1's are terminated on an RJ48 jack. If the T1 line is provided by a telecom company, a T1 Network Interface Unit (NIU) is often installed with an RJ48 jack. A T1 NIU may also be referred to as a 'smart jack,' a device which allows remote, and on-site, loop up and testing capability, as well as indicator lights for basic fault isolation. An RJ48 jack accepts an 8-position, 8-contact (8P8C) modular connector. It's important to note that RJ48 jacks and connectors are often confused with RJ45 (Ethernet) jacks and connectors, because they may look identical, but RJ48 uses a different wiring standard and a different pinout - uses pins 1, 2, 4 & 5. However, some RJ48 jacks and connectors have a keyed notch on one side.
What is a phone jack?
Generally speaking, a phone jack is a small, plastic, standard sized connection that is used to plug a telephone line into an outlet on a wall. Sometimes the both the outlet and the jack itself are referred to as phone jacks. Phone jacks usually have two pairs of wires, red and green, yellow and black. A phone jack is a modular (RJ11) socket in the wall, phone, fax machine, modem , or computer device that lets you insert a telephone wire with modular connectors at the end to allow connecting a communicating device to the telephone system. Not all modular connectors are the same. RJ11 is used for phone systems. RJ45 are different sized connectors used for internet (ethernet) wires. Before modular connectors became popular, a phone jack was a square shaped jack with a round hole in each corner. A wire from a phone would end in a plug similarly shaped with metal connectors that would insert into the holes in the jack. To prevent plugging in incorrectly, some of the holes were positioned off center.
