[4] V.33 is an ITU-T recommendation for a modem operating as full-duplex on a 4-wire point-to-point leased line allowing bidirectional data transfer at either 14.4 kbit/s. V.34 (09/94) is an ITU-T recommendation (superseded) for a modem, allowing up to 28.8 kbit/s bidirectional data transfer using TCM modulation. Other additional defined data ...
Telenet was an American commercial packet-switched network which went into service in 1975. [ 1 ] [ 2 ] It was the first FCC-licensed public data network in the United States. [ 3 ] Various commercial and government interests paid monthly fees for dedicated lines connecting their computers and local networks to this backbone network .
The network was initially based upon a dedicated modular packet switch using DCC's TP 4000 communication processor hardware. The operating system and the packet switching software were developed by Telenet (later on GTE Telenet). BT bought Telenet's system via Plessey Controls of Poole, Dorset who also sold Telex and Traffic light systems. PSS ...
Telenet was purchased in 2000 by Dick Callahan's telecommunications holding company, Callahan Associates International, [2] in a deal valued at $969 million at the time. [3] Since 11 October 2005, Telenet was listed on the Euronext Brussels stock exchange under the ticker TNET, until it was acquired by Liberty Global on October 16 2023. [4]
A given headend may have between 1–12 CMTSs to service the cable modem population served by that headend or HFC hub. One way to think of a CMTS is to imagine a router with Ethernet interfaces (connections) on one side and coaxial cable RF interfaces on the other side. The Ethernet side is known as the Network Side Interface or NSI. [3] [4]
A modem flap is when the connection by the modem to the head-end has been dropped (gone offline) and then comes back online. The time offline or rate of flap is not typically recorded, only the incidence. While this is a common occurrence and usually unnoticed, if a modem's flap is extremely high, these disconnects can cause service to be ...
Terminal-emulator software typically allows the user to send Hayes commands directly to the modem, and to see the responses. In this example, the user of computer A makes the modem dial the phone number of modem B at phone number (212) 555-0100 (long distance). After every command and response, there is a carriage return sent to complete the ...
In 2014 the Ziggo hybrid fiber-coaxial cable network (a broadband network that combines optical fiber and coaxial cable) passed 7.140 million homes in the Netherlands. [20] In 2020 it consisted of 40,350 km (25,072 mi) of fiber-optic cables that transported 97% of the total data volume in the network.
