7 Jumper The modular modem has three 2 pin headers or jumpers to put the modem into the two wire leased line mode. Those jumpers have no affect for normal dial-up modem operations and should only be moved to put the modem into leased line mode. To set the modem to the leased line mode utilize the following settings: JP1 ON for both modems Originate mode JP2 ON, JP3 OFF Answer mode JP2 OFF, JP3 ON Phone Line Connector Tip and Ring The two pins required for connecting to the phone line or leased line. RJ11 wiring 6P6C connector showing the location of pin 1 Cables sold as RJ11 often actually use 6P4C RJ14 connectors (six position, four conductor), with four wires running to a central junction box. Two of its six possible contact positions connect tip and ring, and the other two conductors are then unused. 6P2C and 6P6C can also be found in stores.

8 The conductors other than the two central tip and ring conductors are used for various things such as a ground for selective ringers, low voltage power for a dial light, or for 'anti-tinkle' tinkle' circuitry to prevent pulse dialing phones from ringing the bell on other extensions. With tone dialing, anti-tinkle tinkle measures are not required.

9 MODE OF OPERATION- AT COMMAND SET Modems are used to originate or answer telephone calls and establish links with other modems for the purpose of transmitting data between two locations. Note: Jumpers, J1, J2, and J3 need to be removed while entering the AT command set. After you have completed the hardware connection, you will now be able to communicate with the modem and establish connections with remote devices. Controlling the modem functions is accomplished by using AT commands. Those commands are used to instruct the modem to perform functions such as dialing or answer a call. These commands are normally automatically issued by the communications software however with some applications (leased line modems) you will need to configure the modems through a terminal emulator to store your commands. The modem automatically accepts and processes AT commands on most standard DTE (data terminal equipment) speeds and parity settings. For each command issued, the modem will respond with a result code informing you of the modem status. The format of the basic AT commands and result codes are as follows: Command>> AT <command> <CR> Result>> OK or ERROR AT = Attention what follow is a command <Command> = a valid command <CR> = carriages return or enter key OK = result code meaning: the modem has accepted the command ERROR = result code meaning: the modem has not accepted the command Following codes are a subset of AT commands set, to get you up and operational utilizing the leased line option: Command ATM<0> ATM<1> ATM<2> ATM<3> ATL<0> ATL<1> Description Speaker is always off Figure is on during call establish but goes off when carrier is detected(default) Speaker is always on Speaker is off during dialing and receiving the carrier but on during answering Off or low volume Low volume(default)

10 ATL<2> Medium volume ATL<3> High volume AT&F Reset set modem to default AT&W&W1 Save current configuration AT+MS AT+MS Select / force modulation- this command is useful if you are required to limit the modem to a specific modulation or line speed Example AT+MS=V32,0,9600,9600<CR> This will force the modem to connect at 9600 baud for transmit and receive. This is a good starting point to connect your lease line modems. Syntax: AT+MS=<carrier>,<auto mode>,<min_tx_rate>,<max_tx_rate> As a minimum command set, enter the red-lighted commands to set up your modems for lease line. Jumpers, J1, J2, and J3 need to be removed while entering the data. After the commands have been successfully entered then set up your jumpers for originate and answer modems. The orange -lighted commands maybe required based on the grade of the phone line. After you have changed your settings and set the jumpers, re-power your modems. After a 5 second delay they will begin to negotiate and connect at the appropriate speeds. Once the modems have connected, you should have the CD led illuminated. Modulation Control Commands +MS - Modulation Selection This extended-format compound parameter controls the manner of operation of the modulation capabilities in the modem. It accepts six sub parameters. Syntax +MS=[<carrier>[,<automode>[,<min_tx_rate>[,<max_tx_rate>[,<min_rx_rate> [,<max_rx_rate>]]]]]] Where possible <carrier>, <min_tx_rate>, <max_tx_rate>, <min_rx_rate>, and <max_rx_rate> values are listed below; Modulation <carrier> Possible (<min_rx_rate>, <min_rx_rate>, (<min_tx_rate>), Bell 103 B Bell 212 B Rx/75 Tx or 75 Rx/1200 Tx V.21 V21 300

12 The RS232/RS485 converter shown above can be purchased separately from LX technologies. If purchased from another vendor the converter needs to support 2 wires RS485. RS422 converters will not work adequately. Compliance The LXV92 is certified with FCC part 68 and Canada DOC (IC) CS-03 rules. FCC part 68 This modem is FCC Part 68 Certified. FCC part 15 This modem is FCC part 15 Compliant. EMI/RFI emissions are rated at 3KV protection on the tip and ring to chassis ground. Industry Canada CS-03 - This modem is Canada CS-03 certified CTR21 statement: This equipment has been approved to [Council Decision 98/482/EC- CTR 21 ] for pan-european single terminal connection to the public switched telephone network (PSTN). However, due to variances between the individual PSTN s provided in different countries, an unconditional assurance of successful operation on every PSTN termination point cannot be provided. In the event of a problem, you should contact your equipment supplier. The Federal Communications Commission (FCC) has established rules, which permits this device to be directly connected to the telephone network. If this device is malfunctioning, it may also be causing harm to the telephone network; this device should be disconnected until the source of the problem can be determined and until repair has been made. If this is not done, the telephone company may temporary disconnect service. The telephone company may make changes in its technical operations and procedures; if such changes affect the compatibility or use of this device, the telephone company is required to give adequate notice of the changes. If the telephone company requests information on what equipment is connected to their lines, inform them of the following. The telephone number and the device it connected to. The ringer equivalence number (REN). The device uses and RJ 11 type jack. The FCC Registration number. The REN (ringer Equivalence Number) is used to determine the number of devices that may be connected to the telephone line. Excessive REN s on the telephone line may result in devices not ringing in response to an incoming call. In most, but not all areas, the sum of the REN should not exceed five (5.0). To be certain of the number of devices that may be connected to a line, as determined by the total REN s, contact the local telephone company. The telephone consumer protection act of 1991 makes it unlawful for any person to use a computer or any other electronic device, including fax machines, to send any message unless such message clearly contains in a margin at the top or bottom of each transmission page or on the first page of the transmission, the date and the time, it is sent and an identifier of the business or other entity, or other individual sending the message and the telephone number of the sending machine or such business, other entity, or individual. (The telephone number provided may not be a 900 number or any number of which changes exceed local or long-distance transmission charges.) State tariffs. Contact state public utility commissions for information. In order to program this information into your fax machinefor fax/ modem, consult your fax machine user s manual for setup instructions.

13 Glossary Baud - Bytes per second. When a computer file command, document, or other format is transmitted over a line, it must be broken down into packets (segments) of information. Baud is the measure of the transmission speed of those packets. Transmission speeds typically range from 2400 baud to 56K (thousand) baud, (but can exceed those parameters depending on the type of transmission line or medium used). Byte - Eight (or seven, sometimes) bits make up one byte. A byte contains information, which the computer can recognize and process according to a program s operating parameters. A word processing program, for example, recognizes the one byte of information that is transmitted from the keyboard to the CPU when the "A key is clicked, and displays an A on the screen in accordance with its operating parameters. Data transmission speeds are typically measured in bytes per second, meaning the number of bytes which can be processed and sent depending on hardware and software limitations, (modem speed, transmission medium, line type, etc.) FIFO - First in, first out, a description of a type of buffer. Buffers can only hold so much information before they are full. Some are like buckets, where, when they become full, retain the information that is already contained in the buffer, and disregard any additional information. Some buffers are like pipelines, where information goes into the buffer in one end, and, as more information is added, the latest information is retained, and the oldest is pushed out the other end, either to storage on a disk, for instance, or printed on a printer, or even simply disregarded. Firmware - Firmware is changeable programming information housed on (or in) semipermanent hardware, like CPU chips. While hardware is generally unchangeable, and software is generally wholly changeable, firmware provides a measure of security by storing the changeable programming information on a hard-to-change medium electrical circuit board, ready to perform its functions until being re-programmed. (See also hardware and software.) Half-Duplex - Half-Duplex is a description of communications between two entities which use the same lines or media for transmission and receiving. In the illustration below, an ICD-810 uses half duplex (2-wire) communication to send and receive command instructions and event messages with an IAD-4514 Hardware - The unchanging computer equipment, printers, hardware panels, and other devices in a computer system. Hardware is generally unchangeable in that users cannot, for example, easily modify it to make it work in anything other than its original set parameters. (See also firmware and software.)

14 LED - Light Emitting Diode. Hardware panels and devices often feature red, green, or yellow LED s which allow security operators to visually verify the operational status of the equipment. LED s emit a glowing light, which is a visual cue to system operating status. Networking - Networking is the connection of computer servers, workstations, hardware panels, printers, and other assets to allow for file sharing, system-wide updates, and efficient communication between users. Local Area Networks (LAN s) generally cover a building or small geographic area, and Wide Area Networks (WAN s) generally cover a larger geographic area or several widely scattered buildings. Port - A generic term for an input/output connection on a computer board. A port for serial communications, for example, would accept an appropriate cable to allow a serial device to be connected to the computer. RS A type of communication module which is fitted to hardware devices to allow them to communicate with a controlling computer or other hardware panel. The RS-232 standard allows serial communication along a line from one controlling device to one receiving device. (See serial.) RS-232 communications are limited to 50 feet (about 15 meters) between controlling to receiving hardware, (without line extenders). RS A type of communication module which is fitted to hardware devices to allow them to communicate with a controlling computer or other hardware panel. The RS-485 standard, unlike the RS-232 standard, allows multiple receiving devices to communicate with a single controlling device, using one line, (known as multiple drops or points where receiving hardware can be attached to the single line). The RS-485 communication standard allows the communication line to be 4,000 feet long, (without line extenders). Serial - Serial communications, as compared to parallel communications, allow communications in one direction at any given time over a single communication line. For example, Device A communicating via serial standard to Device B would only be allowed to send to Device B when it was not receiving along the single communication line. Parallel communication, on the other hand, allows simultaneous sending and receiving along a single communication line. Serial Port - A hardware connection on a computer board which accepts a serial cable plug-in, and allows serial communications between the computer and associated hardware devices, (like a printer, for example).
