Modem Terminology Definitions
Applicable to: World-Wide
EKTS:
Stands for Electronic Key Telephone Set which is just a fancy way of saying "touch-tone". This is needed for the analog emulation, so that touch-tone will work.
FYI.. EKTS needs to be turned off for the Waverunner.
Extended Mode:
Extended Mode is a special feature of the IBM 7845 which emulates an analog telephone with one B channel. In effect, allowing analog devices to use the ISDN line.
The SPID that you place into the 7845 is the channel that the analog emulation uses. The other SPID should be programmed into another ISDN device. A common customer mistake is to program the Waverunner or some other device with the same SPID as the 7845 is using in extended mode.
The ring voltage of the 7845 in extended mode is not standard and below voltage. This means that some analog devices may not be able to understand if the line is ringing. Like the 7852-10 which can't pick up whether or not the line is ringing.
ISDN:
ISDN stands for Integrated Services Digital Network ISDN can carry both voice and data over the same line simultaneously.
ISDN and Digital PBXs are NOT the same. To interface with a PBX use a digital to analog converter.
Legacy Adapters:
Adapters that are not Plug and Play compatible are known as legacy adapters. Legacy adapters often require the user to move jumpers on the adapter to configure resources.
Prior to installing a legacy adapter into a Plug and Play compatible system, you should use the IBM system Configuration/Setup Utility program to make the desired resource (IRQ, I/O address or memory range) unavailable to Plug and Play. This will prevent conflicts between Plug and Play adapters and the legacy adapter and also inform the user of which system resources are available and which are not.
Network Terminator:
A network terminator is a device that is provided by the user to interface an ISDN device ( like IBM's Waverunner ) to the ISDN network
PCMCIA Modem Card:
PCMCIA cards, now known as "PC Cards" were once thought of as a simple way to add memory and modest amounts of storage to handheld and laptop computers, today PCMCIA (Personal Computer Memory Card International Standard Association) standard for plug in add-on cards are offered by many, if not most, modem manufacturers.
PCMCIA requires software which is included in some, but not all, operating systems. Generally the more recent the operating system version, the more likely PCMCIA support is provided by default, or is included as an option. View the following outline for a summary of what PCMCIA support is required for each operating system:
DOS:
Requires "Card and Socket Services" provided by vendors supporting the PCMCIA card to be used. Included in IBM DOS is IBM card and socket services, other support is available from Phoenix, CardSoft and others. Note: these PCMCIA support software products require particular attention to memory management, they may require exclusion statements in the Upper Memory Area (UMA) when EMM386.EXE is loaded in the CONFIG.SYS file.
Windows 3.1:
Requires "Card and Socket Services" provided by vendors supporting the PCMCIA card to be used. Included in IBM DOS is IBM card and socket services, other support is available from Phoenix, CardSoft and others. Note: these PCMCIA support software products require particular attention to memory management, they may require exclusion statements in the Upper Memory Area (UMA) when EMM386.EXE is loaded in the CONFIG.SYS file. They may also require exclusions in the [386Enh] section of the SYSTEM.INI file. There is no native Windows 3.1 PCMCIA device support.
Windows 95:
Most PCMCIA sockets and many cards are supported by Windows 95 Plug and Play by running the PCMCIA wizard. It will disable the real-mode (DOS) drivers in the AUTOEXEC.BAT and CONFIG.SYS files or, in some cases, disable Plug and Play PCMCIA support if there is a risk of incompatibility. Windows 95 will, in most cases, support your PCMCIA card and socket and configuration will be automatic. PCMCIA real mode card and socket services my often be utilized in cases where your PCMCIA socket (chip) is not supported by native Windows 95 drivers.
OS/2:
Most PCMCIA sockets and many cards are supported by OS/2. It will disable the real-mode (DOS) drivers in the AUTOEXEC.BAT and CONFIG.SYS files.OS/2 will, in most cases, support your PCMCIA card and socket and will automatically be installed.
NT 4.0:
Most PCMCIA sockets and many cards are supported by Windows NT by clicking on and configuring your new devices in the PCMCIA and Modems icon in the Control Panel. Window NT 4.0 will, in most cases, support your PCMCIA modem card and socket.
Plug and Play Adapter:
Plug and Play is a technology designed to automate and simplify the setup and configuration of your computer when you install new options. Plug and Play adapter support is built into the system board in your computer. Plug and Play adapters are configured automatically and require no jumpers to be set.
PCI adapters generally are Plug and Play compatible. Some new ISA adapters also support Plug and Play.
A Plug and Play adapter comes with identification and configuration specifications set in memory on the adapter, to provide installation information to the computer during startup. This information is recognized by the input/output (I/O) bus and interpreted by the computer basic input/output system. The BIOS then automatically configures the adapter around the resources already in use by other devices.
Some Plug and Play adapters come with a jumper to disable the Plug and Play feature, at which point it becomes a legacy adapter.
SPID:
What is a SPID
A SPID is an ISDN device identifier, much like a network address. Most of our customers will be given 2 SPIDs for their ISDN line. Depending on the telephone company and the switch type each SPID will consist of 10-14 digits. These SPIDs usually consist of a their assigned telephone number, plus some other digits.
Examples:
9194372242 001
9194372241 0001
10 9194372248 00
