Page 102 MultiModemISDN User Guide Symbol 2B1Q (2 bits, 1 quarternary)—A line code at layer one for the BRI U interface. Two bits of data (2B) are mapped into one of four line values (1Q, or 1quarternary). This coding scheme allows a single copper pair to carry 160 Kbps of information bidirectionally and simultaneously at a distance of up to three miles.
Page 103 Glossary BONDING Specification 1.1— The Version 1.1 BONDING specification (September 1993) incorporates changes to the 1.0 specification resulting from interworking tests among various vendors, and comments from the TIA standardization process. No changes were made to the BONDING algorithm or procedures. bps (bits per second)—The unit of speed at which data bits can be transmitted or received.
Page 104 MultiModemISDN User Guide may refer to the function performed by an entity attached to the Universal Serial Bus; for example, a data/FAX modem device. Devices may be physical, electrical, addressable, and logical. When used as a non-specific reference, a Universal Serial Bus device is either a hub or a function.
Page 105 Glossary frequency—A characteristic of an electrical or electronic signal which describes the periodic recurrence of cycles. Frequency is inversely proportional to the wavelength or pulse width of the signal (e.g., long wavelength signals have low frequencies and short wavelength signals yield high frequencies).
Page 106 MultiModemISDN User Guide LAPB (Link Access Procedure Balanced)—Based on the X.25 Layer 2 specification. A full-duplex, point-to-point, bit-synchronous protocol commonly used as a data link control protocol to interface X.25 DTEs. LAPB is the link initialization procedure that establishes and maintains communications between the DTE and the DCE.
Page 107 Glossary OHCI (OpenHCI): Open Host Controller Interface Specification for USB. All transfers on the USB are initiated by the host system’s host controller. The host controller is responsible for controlling traffic on the USB and can be appropriately programmed to transfer data to and from USB devices.
Page 108 MultiModemISDN User Guide R reference point—Establishes the boundary between non-ISDN compatible equipment (TE-2) and the IDN network. TAs are used to convert the communication protocol used by the non-ISDN termnials to the desired BRI or PRI protocol. Non-ISDN (TE2) terminal equipment connects to IDN at the R-Reference point with a TA.
Page 109 Glossary T—Provides the connection between the NT1 and NT2. Can be internal to or external from the PABX. Provides the connection between the NT1 equipment and the TA or TE-1. Can provide both Primary Rate and Basic Rate services. TA—See terminal adapter . TCP/IP (Transmission Control Protocol / Internet Protocol)—A multi-layer set of protocols developed by the US Department of Defense to link dissimilar computers across dissimilar and unreliable LANs.
Page 110 MultiModemISDN User Guide Universal Serial Bus: A collection of Universal Serial Bus devices and the software and hardware that allow them to connect the capabilities provided by functions to the host. Universal Serial Bus Device: Includes hubs and functions. See device. Universal Serial Bus Driver: The host resident software entity responsible for providing common services to clients that are manipulating one or more functions on one or more Host Controllers.
