NAME
/DCD
DESCRIPTION
/DCD is an active low output from the modem. The AT&C command controls when the XE5620 asserts /DCD. /CTS is an active low output from the modem. The modem asserts /CTS to indicate that it can accept data from the terminal equipment on /TXD. RESET is an active low input which initiates a modem hardware reset. RESET must be active for a minimum of 100 milliseconds for a proper modem reset sequence. No external reset is required; if none is used the RESET signal should be left open. /DSR is an active low output from the modem. The AT&S command controls when the XE5620 asserts /DSR. /RTS is an active low input to the modem. /RTS indicates to the modem that the host has data to send. /DTR is an active low input to the modem. The AT&D command determines how the modem will interpret activity on /DTR. /RXD provides the path for received data and modem responses to be sent from the modem to the host terminal equipment.

NAME
/TXD
DESCRIPTION
/TXD provides the path for transmitted data and modem commands to be passed from the host terminal equipment to the modem. The /RI signal reports on the presence of an incoming ring signal. When a ring occurs across Tip and Ring, the /RI output goes low and toggles with the cadence of the ring signal.. Ground provides the reference voltage for all host interface signals. SPKR allows connection of a speaker to monitor modem operations. SPKR cannot directly drive a speaker. An amplifier with a minimum input impedance of 300 ohms is required. The signal on SPKR is controlled by the ATL and ATM commands. No internal connection VCC provides 3.3 volt power to the modem. No Internal Connection No Pin No Internal Connection The Ring and Tip signals provide modem the connection to the telephone line. FCC Part 68 Rules require a 1500 volt isolation barrier between the telephone line and all other circuits. This isolation must be preserved throughout the system. The telephone company places a DC "Battery" voltage across Tip and Ring on all public switched telephone lines. The XE5620 will operate regardless of the polarity of this "Battery" voltage. The "Battery" voltage drives up to 100 milliamps of DC loop current. UL60950 requires minimum creepage and clearances distances be maintained between the Tip and Ring traces and all other circuits. Clearance is the shortest distance between conductive circuits; creepage is the distance between conductive surfaces along the surface

Application Note: Using a 68-Pin PLCC Socket
The XE5620 can be inserted into a socket for a 68-pin PLCC device. The HyPLCC package uses only 20 pins; 15 on one side and 5 on the opposite side. Alignment within the socket is critical for all pins of the XE5620 to make contact with the appropriate pins of the PLCC socket. The drawing below illustrates how the XE5620 can be inserted into the 68-pin PLCC socket. Emulation Technology's S-SMT-17-068-A socket is representative of sockets that can be sued with the XE5620.

XE5620 AT Commands
The XE5620 uses "AT" commands for configuration and control. This section describes the AT command format and lists the AT commands, Registers and Result codes. XE5620 "AT" commands have two operational modes; Command Mode, Data Mode and FAX mode. Data Mode: The XE5620 enters data mode after it connects to a remote modem and issues the appropriate result code. In the Data Mode the modem sends all data presented on Transmit Data (/TXD) to the remote modem and puts data from the remote modem onto Received Data (/RXD). When the modem exits data mode, it issues a "NO CARRIER" result code. Command Mode: The XE5620 enters command mode on power-up, reset, a lost connection, or receipt of the escape code. In command mode the modem accepts commands from the host on transmit data. Appropriate result codes are returned on received data. Fax Mode: The XE5620 enters Class 1 fax mode on receipt of AT+FCLASS=1. In fax mode commands and responses are issued at 19,200 bits per second; the character format is 8 bits no parity. The modem accepts fax commands only in fax mode. The A/, ATO, AT&T and escape commands are not valid in fax mode. Command Line Format Command lines issued to the modem follow a strict format. Each command begins with the prefix AT. The command buffer stores the command line and executes it upon receipt of a carriage return. Until executed, the command line can be edited with the backspace key. Command Prefix - Each command, except the A/ command, 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 prefix identifies the speed and parity of the commands sent to the modem. The modem deternies data rate by measuring the width of the incoming bits. Parity is determined by comparing the parity bits of the "A" and the "T." Command Line - Commands may be strung together in a single command line of up to 36 characters. Commands are executed in the sequence they appear. Spaces may be inserted into the command line but 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 36 characters, including the AT prefix. If the command buffer overflows, the modem issues an "ERROR" result code and commands are not executed. Command Line Editing - The backspace edits a command line before it is executed. The backspace key, (Control and H simultaneously on some systems), erases the previous character in the command line. 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 modem to re-execute the last command line. This is the only command which does not require the "AT" prefix. Omitted Parameters - Most commands include a parameter which determines how the functions will be set. When the command parameter is omitted from the command string, it is assumed to be a 0. Escape Characters - A 3 character escape sequence may be entered to switch the modem into command mode while on line. The escape character, set by Register S2, must be entered 3 times in succession to execute the escape. An AT command must then be entered within the period defined by S12 to enter command mode. The default escape sequence is "+++." Result Codes - The modem issues a result code after each action. Result codes may be sent as full words, one or two digit numeric codes, or may be disabled all together. 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.

FCC Instructions
The XE5620 complies with part 68 of the FCC Rules and Regulations. With 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 you calling area. 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. 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 you experience trouble with this device, please contact XECOM at (408) 945-6640 for information on obtaining service or repairs. 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. 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.
