`
`This equipment generates and uses radio frequency energy,
`and if not installed and used in strict accordance with the
`instructions in this manual, may cause interference to radio and
`television reception. It has been tested and found to comply
`with the limits for a Class B computing device under Part 15 of
`the FCC Rules, which are designed to provide reasonable
`protection against such interference in a residential installation.
`However, there is no guarantee that interference will not occur
`in a particular installation. If this equipment does cause
`interference to radio or television reception, which can be
`determined by turning the modem on and off, the user is
`encouraged to try to correct the interference by one or more of
`the following measures:
`
`0
`
`Reorient the receiving antenna.
`
`0 Move the modem away from the receiver, or relocate
`the receiver with respect to the modem.
`
`0
`
`Plug the modem into a different outlet so that the
`modern and receiver are on different branch circuits.
`
`If necessary, you should talk to your dealer or any experienced
`radio/television technician for additional suggestions. You
`may find a booklet prepared by the FCC entitled "How to
`Identify and Resolve Radio-TV Interference Problems” helpful
`in resolving any problems. This booklet is available from the

`operated telephone lines are subject to local and state
`regulatory policies, and possible additional state special
`features.
`
`The telephone company has the right to make changes
`to their network which may affect the operation of your
`equipment, provided you are given adequate advance
`written notice to permit correct operation.
`
`In the event of operational problems, disconnect your
`unit by removing the modular jack from the telco’s
`tennination. If your regular phone still works properly,
`your modem may need to be returned for repairs in or
`out of warranty. If after disconnecting the equipment,
`your regular telephone does not operate correctly,
`notify your telephone company that they may have a
`problem, and request prompt service at no cost to you
`the user. If a problem is found in premises wiring not
`telco-installed, you will be subject to an authorized
`service charge. If a fault is found in telco-installed
`wiring, you may be subject to a charge for the service
`call.

`Introduction
`
`This manual provides a comprehensive guide for setting up and
`using the Telebit T1000. It assumes that you are experienced
`with your computer or terminal, and that you have a basic
`understanding of data communications.
`
`You can save yourself a lot of time if you start by following the
`instructions in the T1000 Fast Start Guide, which is a separate
`booklet provided to help you get started using your modem as
`quickly as possible. If you have special requirements or
`experience any problems while using the Fas: Start Guide, refer
`to this manual for additional information.
`
`As you read through this manual, you will find that your T1000 is
`much more than a modem. In many ways it can serve as your
`desktop communications processor for dial-up applications.
`Advanced modulation techniques used in the T1000 provide high
`speed data communications while ensuring error—free
`transmission regardless of line ‘quality. The T1000 is capable of
`communicating at speeds up to four times faster than competitive
`modems operating at 2400 bps. It also compensates for line
`impairments which exist on dial-up connections. This high
`speed error-free transmission capability is achieved through the
`application of Te1ebit’s unique Packetized Ensemble Protocol“!
`(PEP).
`
`For maximum flexibility, the T1000 supports two user interface
`modes: Conventional and Enhanced Command Mode. In
`Conventional Command Mode, the T1000 works with most
`popular data communications software configured for Hayes®
`V-series?" modems. The Enhanced Command Mode allows
`access to an extended set of functions which are common to
`Telebit TrailBlazer® modems.

`Intoductlon
`
`Some of the major features offered by the T1000 are discussed
`below:
`
`Two Modes of Sottware compatlblllty
`
`The T1000 is configured at the factory to initially power-up in
`Conventional Command Mode. This allows the modem to be
`used with V-series compatible software without requiring any
`modifications. A special character provides access to the extra
`functions available in Enhanced Command Mode.
`
`The T1000 can be easily reconfigured to operate in Enhanced
`Command Mode to take advantage of software designed
`explicitly for PEP modems, such as the Te1ebitTrai1Blazer or
`T2000.
`
`Packetlzed High Speed Data Transmission
`
`Using the Packetized Ensemble Protocol (PEP), the T1000 can
`transmit or receive asynchronous data with a throughput of up to
`9600 bps.
`
`compatibility with Slower Modems
`
`For use with lower speed modems, the T1000 is compatible with
`the 300 bps Bell 103 and 1200 bps Bell 212A standards, as well

`
`While operating in PEP mode, the T1000 assembles packets of
`data and adds to each packet a 16-bit Cyclic Redundancy Check
`(CRC) for the purpose of error detection. If the receiving modem
`detects an error, it requests a retransmission of data. All error
`detection and correction is completely transparent to the user and
`does not require any additional computer resources.

`Introduction
`
`MNP“ Support E
`
`The T1000 can be configured to support MNP Classes 1 through
`5 while operating in Slow (non-PEP) mode. When a connection
`is established, the modems at each end automatically determine
`the highest MNP class supported by both modems.
`
`Automatic Transmission Mode Selectlon
`
`At the time a telephone connection is made, the T1000
`automatically selects the correct transmission speed by matching
`the transmission mode of the remote modem. If the remote
`modem is a PEP modem, the T1000 operates in PEP mode using
`the Packetized Ensemble Protocol. This provides maximum data
`throughput for any given telephone connection. If the remote
`modem is not a PEP modem, the T1000 automatically
`determines the correct transmission mode to use while
`communicating with the remote modem.
`
`Adaptlve Duplex?" for Maximum Throughput
`
`In order to improve overall system performance, the T1000
`provides an Adaptive Duplex capability while operating in PEP
`mode. This feature allows the T1000 to optimize overall
`throughput by dynamically varying the allocation of
`transmission capacity and rate ofdata flow between modems to
`match the bidirectional traffic load.
`
`Real Tlme Llno Analysls and Adaptation
`Each time a connection is made in PEP mode, the modem
`performs a line analysis and determines the operating parameters
`of the transmission. The line characteristics are monitored by the
`T1000 during the entire connection, and operating characteristics
`are adjusted as required for optimum data transmission.

`Self Test, Internal Dlagnostlos
`and Llne Monitoring Data
`
`Each time you turn on the T 1000, a series of internal logic tests,
`memory tests, and internal loop back checks are performed. In
`addition, the T1000 provides data transmission statistics, such as
`line quality analysis, signal-to~noise ratios, frequency offset
`measurements, data flow analysis and error rates.
`
`Call Progress Reporting and Monitoring
`
`After placing a call using the T1000, a message provides the
`status of the call. The report format is selectable and can be
`presented in either text or numeric mode. A built-in speaker
`provides audio feedback of a cal1’s progress.
`
`Auto-Dlal and Auto-Answer
`
`The Tl000's Dial command allows you to place the T1000 off-
`hook, have it wait for a dial tone, and then automatically dial a
`telephone number presented by the computer or terminal. The
`T1000 can also be configured to allow your computer or terminal
`to automatically dial the first number in the number directory via
`the DTR control signal. Both pulse and tone dialing are
`supported.
`
`When configured in auto-answer mode, the T1000 will
`automatically answer an incoming call, allowing you to leave the
`T 1000 unattended.
`
`Hardware and Sottware Flow Control
`
`The T1000 lets you specify the method of data flow control when
`transmitting infonnation. You can select a software protocol
`such as XON/XOFF and/or RTS/CI‘S flow control using the RS-
`232 control signals.

`
`Using the T1000
`
`This chapter presents a general overview of the T1000 operating
`characterisfics, and shows you how to enter commands to set
`parameters and control the modem’s operation.
`
`It is assumed that you have installed the T1000 by following the
`instructions in the T1000 Fast Start Guide or Chapter 2 of this
`manual.
`
`If the modem is connected directly to a terminal, you can simply
`input the commands from the keyboard. When the modem is
`connected to a computer, you must use its data communications
`software or a terminal emulation program to configure and use
`the modem.
`
`If you intend to use the modern with a mainframe computer or
`other serial device which will only be accepting incoming calls,
`you can use a terminal (or personal computer with a terminal
`emulation program) to preconfigure the modem’s operating
`parameters and save them in non-volatile memory.
`
`Memory Organization
`
`Figure 3-1 shows the relationship between the active configur-
`ation, the factory defaults and the non-volatile memory. The
`active configuration stored in RAM defines the current operating
`characteristics of the modern.
`
`The factory defaults are the operating parameters most com-
`monly used for data communications which are permanently
`stored in ROM. These parameters can be restored to the active
`configuration by issuing an &F command or by reinitializing the
`modem as described later in this chapter.

`
`Using the T1000
`
`['he current operating parameters can be modified and saved in
`ion-volatile memory as Profile A or Profile B via an &W(n)
`:ommand. A selected profile can be restored to the active
`:onfiguration by issuing an &E(n) or Z(n) command in
`Enhanced Command Mode, or by issuing a Z(n) command in
`Zonventional Command Mode. When a selected profile is
`estored, its settings replace the current operating parameters.
`
`['he S255 register determines which profile is used when the
`nodem is powered up or reset, or when one of the above
`:ommands is issued without a (n) parameter.
`
`Selecting Conventional or
`Enhanced Command Mode
`
`Before powering up your T1000, you should determine which
`zommand mode will assure compatibility with your computer's
`zlata communications software.
`
`Conventional Command Mode is designed for software that does
`not have the ability to utilize the special features of PEP modems.
`This is typically indicated by the absence of modem-specific
`setup options, or applications that assume general Hayes
`sommand compatibility. The T1000 Conventional Command
`Mode should be compatible with any data communications
`software that supports Hayes V-series modems.
`
`Enhanced Command Mode allows the T1000 to be compatible
`with software designed explicitly for PEP modems. If your
`application provides support of the advanced features of PEP
`modems, such as the TrailBlazer Plus or T2000, then the T1000
`Enhanced Command Mode is the preferred choice. The same
`holds true for data communications software that supports other
`PEP modems, e.g. DCA Fastlink, Raca1—Milgo RM-1822D, or
`Ven-Tel Pathfinder.

`
`
`
`Using the T1000
`
`Powering Up the Modem
`
`The power switch (1/0), mounted on the rear of the modem, is
`used to turn the modem ON or OFF. Each time it is turned on,
`the modem runs a series of power up diagnostic tests. After
`successfully completing the tests, the default configuration
`parameters previously stored in the modem’s non—volatile
`memory are loaded into the modem's registers, and the MR
`(Modem Ready) indicator is turned on.
`
`Initializing the Modem
`
`The modem is shipped from the factory initialized to power up in
`Conventional Command Mode. If you have determined that this
`is most appropriate for your computer's data communications
`software, then no special action is necessary, provided that no
`one has changed the non-volatile memory.
`
`Conventional Command Made
`
`To ensure that the modem is operating in Conventional
`Command Mode, you can reset the modem after the power is
`turned on by performing the following steps:
`
`1 .
`
`2.
`
`3.
`
`Turn on the modem.
`
`Remove the flexible plastic label on the front panel. See
`Figure 3-2.
`
`Press the reset switch by inserting a straightened paper
`clip in the hole marked RESET. Be sure to hold the reset
`switch in until the MR indicator goes off, then turns back
`on.
`
`This stores the factory defaults in Profile A of non-volatile
`memory, and designates Profile A as the power up default. The
`factory defaults are also loaded into the modem’s current oper-
`ating parameters except that _the S0 register is set to 1 and the S45
`register is set to 255. This allows the modem to automatically
`answer an incoming call (S0=1) with remote access enabled
`(S45=255), thereby providing a means for Technical Support to
`remotely access your modem.

`commands while remaining in Conventional Command Mode.
`
`If you will be using data communications software which sup-
`ports Hayes V-series modems, follow the instructions in your
`software manual to configure and use the modem. Configuration
`guidelines and descriptions of the commands and registers are
`presented in Chapter 4, Conventional Command Mode, and
`Chapter 5, Enhanced Command Mode.
