Image Keystone module CAT5 orange.jpg thumb A keystone module for a CAT5 network cable File Keystone wall plate.jpg thumb right A 3 port keystone wall plate A keystone module is a standardized snap in package for mounting a variety of low voltage electrical Jack connector jacks or optical connectors into a keystone wall plate , face plate, surface mount box, or a patch panel . Keystone modules have a rectangular face of 14.5mm wide by 16.0mm high and are held in place with flexible tabs. This allows them to be snapped into a mounting plate with correspondingly sized rectangular holes, called ports. All keystones, regardless of the type of jack they carry, are interchangeable and replaceable. This provides much flexibility in arranging and mounting many different types of electrical jacks in one plate or panel without requiring customized manufacturing. Some keystones use a pass through type connector, where there is a jack on both the front face as well as the rear side. Others only have a jack on the front and employ a different mechanism for hard wiring signal cables to the rear, such as a mini 110 block , an insulation displacement connector , or a Crimp joining crimp or solder connection. Types of modules available Many types of jacks are available in the keystone module format, limited mainly by their physical size, including 6P6C Registered jack RJ 11 modular connector modular jacks telephone 8P8C modular jacks computer networking F connector TV antenna cable satellite RCA jack s audio video Mini DIN connector 4 pin mini DIN S Video jacks HDMI jacks high definition video and audio Optical fiber connector s BNC connector USB jacks Speaker terminal s Banana connector s Binding post s TRS connector 3.5mm TRS connector miniature stereo headphone jack Image Assortment of keystone modules.jpg 650px An assortment of different keystone modules Further reading http discountlowvoltage.blogspot.com 2009 11 how to punch down cat5ecat6 keystone.html How To Terminate Cat5e ... more details
This article refers to a specific series of historic telephones. For multi line phone systems in general, see private branch exchange or key telephone system . A Multi Line Extension , or MLX telephone, is a no longer manufactured series of digital telephone used with several PBX systems sold throughout the 1980s and 1990s by AT&T . This series is notable for the sheer quantity of devices operating in the field, and for its after market continuing long after the manufacturers stopped making them. Their popularity has also contributed to the existence of a sizeable refurbishment market. These phones are typically used with the AT&T Merlin PBX system, originally known as the American Bell Merlin, and which was recently sold under the Lucent Avaya names. The systems they work with include the Merlin Legend , Merlin Magix , and the latest AT&T Partner system. Although there are several versions of MLX telephones, all of them resemble typical business telephones, with anywhere from 30 to 80 buttons on their keypads. Their most common usage is in offices. Communication protocol MLX telephones use an unpublished digital communications protocol. They connect to their host system using an 8P8C 8 position 8 conductor connector, however only the middle 4 positions are actually used. The processing for an MLX telephone is done principally by its host the keypad and display is essentially the equivalent of a dumb terminal contained inside the set. There are provisions for two independent two way voice channels and the data channel similar to ISDN BRI going to a single telephone set. Because each channel is two way, the two voice channels are rarely used simultaneously, except for example, when a voice paging announcement comes over the speakerphone while somebody is using the line, or if an additional multi function module accessory is attached to the phone that permits the second voice channel to be used as a normal analog telephone line , such as for a modem or fax machine .

Orphan date February 2009 Unreferenced date April 2007 CSAFE Communications Specification for Fitness Equipment is a Physical fitness fitness industry wide communications specification developed in 1997 for exercise equipment . As this specification was originally developed by the company FitLinxx, sometimes it is also referred to as FitLinxx . Purpose The CSAFE specification describes the physical wiring scheme as well as the format of the data frames. The CSAFE protocol is designed to work in a master slave fashion. A special I O jack on the exercise equipment accepts a normal 8P8C RJ 45 plug although the wiring scheme has no relation to ethernet wired to a normal RS 232 cable. The CSAFE port also has pins which should be wired to an input Jack plug audio jack . Development In October, 2000, a CSAFE group was formed within FISA http www.fisana.org Fitness Industry Suppliers Association to help coordinate the continued evolution of CSAFE. This group is led by a steering committee with membership from a broad representation of the industry. The CSAFE protocol is licensed on a royalty free basis to any company, person, or organization wishing to use it. Wiring Scheme Most of the pins from the RJ 45 plug should be connected to a normal RS 232 interface configured for an asynchronous communication mode of 9600 baud with 8 data bits, 1 stop bits and no parity. Hardware handshaking for flow control CTS as an input to Slave is not required to support this protocol but is recommended.

Category 6 cable , commonly referred to as Cat 6 , is a cable standard for Gigabit Ethernet and other network physical layer s that is backward compatible with the Category 5 cable Category 5 5e and Category 3 cable standards. Compared with Cat 5 and Cat 5e, Cat 6 features more stringent specifications for Crosstalk electronics crosstalk and system noise. The cable standard provides performance of up to 250 MHz and is suitable for 10BASE T , 100BASE TX Fast Ethernet , 1000BASE T 1000BASE TX Gigabit Ethernet and 10GBASE T 10 Gigabit Ethernet . Whereas Category 6 cable has a reduced maximum length when used for 10GBASE T Category 6a cable, or Augmented Category 6, is characterized to 500 MHz and has improved alien crosstalk characteristics, allowing 10GBASE T to be run for the same distance as previous protocols. Category 6 Like most earlier twisted pair cable , Category 6 cable contains four twisted wire pairs. Attenuation to crosstalk ratio Attenuation , near end Crosstalk electronics crosstalk NEXT , and PSNEXT power sum NEXT in Cat 6 cable and connectors are all significantly lower than Cat 5 or Cat 5e, which uses 24 AWG wire.

Standardized in IEEE 802.3 , Ethernet has largely replaced competing wired LAN technologies. In the OSI reference system, Ethernet is at the Data Link layer. Systems communicating over Ethernet divide a stream of data into individual packets called Frame networking frame s. Each frame contains source and destination addresses and error checking data so that damaged data can be detected and re transmitted. The standards comprise several wiring and signaling variants of the OSI physical layer in use with Ethernet. The original 10BASE5 Ethernet used coaxial cable as a shared medium . Later the coaxial cables were replaced by twisted pair and optical fiber fiber optic links in conjunction with Ethernet hub hubs or Ethernet switch switches . Data rates were periodically increased from the original 10 megabits per second, to 100 gigabits per second. Since its commercial release, Ethernet has retained a good degree of compatibility. Features such as the 48 bit MAC address and Ethernet frame format have influenced other networking protocols.

unreferenced date June 2011 Ethernet Powerlink is a Deterministic algorithm deterministic real time protocol computing protocol for standard Ethernet . It is an open protocol managed by the Ethernet POWERLINK Standardization Group EPSG . It was introduced by Austrian automation company B&R in 2001. This protocol has nothing to do with power distribution via Ethernet cabling or power over Ethernet PoE , power line communication or Bang & Olufsen Bang & Olufsens PowerLink cable. Overview Ethernet Powerlink expands Ethernet with a mixed polling and timeslicing mechanism. This Guaranteed transfer of time critical data in very short isochronic cycles with configurable response time Time synchronisation of all nodes in the network with very high precision of sub microseconds Transmission of less timecritical data in a reserved asynchronous channel Modern implementations reach cycle times of under 200 s and a time precision jitter of less than 1 s. Standardization Powerlink was standardized by the Ethernet Powerlink Standardization Group EPSG , founded in June 2003 as an independent association. Working groups focus on tasks like safety, technology, marketing, certification and end users. The EPSG cooperates with standardization bodies and associations, like the CAN in Automation CAN in Automation CiA Group and the IEC. Physical layer The original physical layer specified was 100Base X Fast Ethernet IEEE 802.3 . Since the end of 2006, Ethernet Powerlink with Gigabit Ethernet supported a transmission rate ten times higher 1,000 Mbit s using somewhat better cable Cat6 . Higher speeds are possible in theory since with standard modules and FPGA s. Repeating hubs instead of switches within the Real time domain is recommended to minimise delay and jitter. Ethernet Powerlink uses IAONA s Industrial Ethernet Planning and Installation Guide for clean cabling of industrial networks and both industrial Ethernet connectors 8P8C commonly known as RJ45 and M1 are accepted.
