upstream RF signals. Upstream RF signals are combined within the device, converted from RF to optical wavelength by a laser and transmitted via optical fiber from the device to a cable operator HE or hub. Excerpt from ANSI/SCTE 87-1 2008, “Graphic Symbols For Cable Systems Part 1: HFC Symbols” 5/8-24 RF & AC Equipment Port, Female Equipment ports of this type are defined by ANSI/SCTE 91 2009, Specification for 5/8-24 RF & AC Equipment Port, Female. This specification serves as a recommended guideline for the physical dimensions of all female 5/8 – 24 equipment ports for RF and AC powering that are used in the 75 ohm RF broadband communications industry. 5/8-24 Plug, Male Adapters Also referred to as a “Stinger”. Coaxial cable connector employed to connect hybrid fiber coaxial (HFC) network transmission line optical nodes, trunk/bridger, and line extender (LE) amplifiers to low loss, large diameter coaxial cable. Male connectors of this type are defined by ANSI/SCTE 111 2010 Specification for 5/8-24 Plug, Male Adapters. This specification serves as a recommended guideline for the physical dimensions of 5/8 – 24 plug (male) hard-line adapters that are used as interconnects in the 75 ohm RF broadband communications industry. It is not the purpose of this standard to specify the details of manufacturing. This type of termination is also known as a “trunk and distribution” coaxial cable connector. 56Kbps Modems More appropriately called Pulse Code Modulation (PCM) Modems, these modems manipulate the way the telephone system works to send data to an analog “modem” type device at speeds of up to 56,000 bits per second (56Kbps). 56K modems work by using ISDN telephone equipment at one end of the connection to manipulate the PCM codes sent across the telephone network. When these PCM sample codes reach the Codec they are translated into a specific series of voltage changes that a PCM modem knows how to interpret. Data sent out by a 56Kbps modem is subject to the same physical restrictions of any modem, so its top “back channel” speed is 33.6Kbps. 56Kbps modems are built against the ITU-T V.90 or V.92 standards.
