XE5614L
XE5614L AT COMMANDS
Modes of Operation The XE5614L uses "AT" commands for modem control and configuration. The XE5614L operates in three modes; Command Mode, Fax Mode and Data Mode. Extensions to the AT command set support fax operation. Data Mode: The modem enters data mode after establishing a modem link and issues a "CONNECT" result code. In Data Mode the modem modulates all signals presented on Transmit Data, Pin 13, and sends them to the remote modem. The modem demodulates the signal from the remote modem and places it onto Received Data, Pin 3, for the host equipment. When the modem exits data mode, it issues a "NO CARRIER" result code. Command Mode: The XE5614L enters command mode on application of power, reset, loss of the connection, or receipt of the escape sequence. In command mode the modem accepts commands from the host on Transmit Data. Appropriate result codes are returned on Received Data at the same speed and parity as the commands. Fax Mode: The modem enters fax mode on receipt of the AT+FCLASS=1 command. Fax commands and responses are issued at 19,200 bits per second; the character format is 8 bits no parity. The modem accepts Class 1 Fax commands only in fax mode. The A/, ATO, AT&T and escape commands are not valid in fax mode. Commands The modem is configured and controlled with AT commands. AT commands follow a strict format. The command line is stored in the command buffer and executed upon receipt of a carriage return. Until executed, the command line can be edited with the backspace key. Command Format - Each command, except A/, begins with the AT prefix. The "A" and "T" may be both upper case or both lower case but cannot be of different cases. The modem uses the prefix to identify the host's speed and parity. The modem determines speed by measuring the width of the incoming bits and parity by comparing the parity bits of the "A" and "T." The modem then returns result codes at the host's speed and parity. Command Line - A command line may include multiple commands. The modem executes the commands in the sequence they appear in the command line. Spaces, inserted to improve legibility, do not fill space in the command buffer. A carriage return terminates the command line and causes the commands to be executed. Register S3 allows the user to select a character other than a carriage return to terminate the command line. Command Buffer - The command buffer holds a maximum of 40 characters, including the AT prefix. If it overflows, the modem issues an "ERROR" result code and commands are not executed. Command Line Editing - A backspace can be used to edit the command line any time before it is executed. The backspace character erases the previous character in the command line. Any character except for the "A" and "T" can be erased. Register S5 allows the user to select a character other than a backspace to edit the command line. Re-Execute Last Command - The A/ command causes the XE5614L to re-execute the command line stored in the command buffer. This is the only command which does not require the "AT" prefix. Omitted Parameters - Most commands include a parameter which determines the command function. When the parameter is omitted from the command string, it is assumed to be a 0. Escape Characters - A three character escape sequence, entered while in data mode, will switch the modem into command mode while remaining on line. The escape character, set by Register S2, is entered 3 times in succession to execute the escape. The default escape sequence is "+++." Result Codes - The modem issues a result code after each action. Result codes may be provided as full words, numeric codes or may be disabled. Each result code ends with a carriage return when numeric result codes are chosen. When full word result codes are chosen, a Line Feed and Carriage Return precede and follow each result code.

XE5614L FCC Registration
All equipment connected to the public telephone network in the United States must have FCC Part 68 Registration. Part 68 registration certifies that the device will not cause harm to the telephone network. The XE5614L provides a user transferable FCC Registration. This permits XE5614L customers to use our FCC registration number without submitting their systems for additional testing. Call Xecom technical support at 408945-6640 with any questions on whether your system qualifies to use Xecom's FCC Registration Number. In your operating instructions you must provide certain information to the end user of the modem. The instructions should include most of the instructions shown below. assembly should be omitted. Only the information regarding the mounting of the device in the final If you experience trouble with this device, please contact XECOM at (408) 945-6640 for assistance. The telephone company may ask you to disconnect this device from the network until the problem has been corrected or until you are sure that the device is not malfunctioning. Your telephone company may make changes in its facilities, equipment, operations or procedures that could affect proper functioning of your equipment. If they do, you will be notified in advance to give you an opportunity to maintain uninterrupted telephone service. If your system causes harm to the telephone network, the telephone company may discontinue service temporarily. If possible, they will notify you in advance. If advance notification is not practical, you will be notified as soon as possible.
FCC Instructions:
This product complies with Part 68 of the FCC Rules and Regulations. On each device shipped, there is a label which contains, among other information, the FCC Registration Number and Ringer Equivalence Number (REN) for this product. You must, upon request, provide this information to your telephone company. The mounting of this device in the final assembly must be made in such a manner as to preserve the high voltage protection between the TIP/RING Connection and the rest of the system. Typically, this may be accomplished by maintaining a minimum spacing .100 mils between the TIP/RING Traces to the RJ-11C Jack and low voltage portion of the system. No additional circuitry may be attached between TIP/ RING and the telephone line connection, unless specifically allowed in the rules. The REN is useful to determine the quantity of devices you may connect to a telephone line and still have all of these devices ring when the number is called. In most, but not all areas, the sum of the RENs of all devices connected to one line should not exceed five (5.0). To be certain of the number of devices you may connect to the line, as determined by the REN, you should contact the local telephone company to determine the maximum REN for your calling area. The device may not be used on coin service lines provided by the telephone company (this does not apply to private coin telephone applications which use standard telephone lines). Connection to party lines is subject to state tariffs.
FCC Labels:
FCC rules also require a label which is visible from the outside of the equipment. The label should display Xecom's name as holder of the FCC Registration, the FCC Registration Number and Ringer Equivalence of the modem. This is the same information which appears on the top of each XE5614L module.
