Dimensions Width : 54mm Height : 5mm Depth : 85.6mm 1.3.3. Electrical description Power requirement Consumption : 800 mW Supply voltage : +5V (from host computer's PC bus) Digital interface The TA provides a rev 2.0 PCMCIA interface, for programming and asynchronous data transfer. This interface allows you to use the PCMCIA socket of the PC answering to every COMx port of any software terminal emulation (in the package there is a disk containing the CCM program to power on and to configure the TA, according to the selected COM port). Connector : PCMCIA 2.0 Asynchronous DTE speed : 300, 1200, 2400, 4800, 9600, 12000, 19200, 38400, 57600 and 115200 bit/s ISDN interface Interface : Bus S 2B+D basic rate access Connector : RJ45 Protocol : EUROISDN 7 Operating temperature Operating ambient temperature : 0øC - +45øC Storage temperature : -20øC - +80øC Relative Humidity : 5% - 92% (non-condensing) 8 1.4. FUNCTIONAL DESCRIPTION 1.4.1. Autobaud The TA CCITA automatically detects DTE speeds (up to 115.2 Kbit/s) and parity format. The valid parity formats are the following: 7 bit + even/odd parity 7 bit + mark/space parity 8 bit no parity 1.4.2. V42bis Data Compression The CCITA TA allows you to select (V.120 asynchronous mode only) the data compression complying with the CCITT V42bis recommendation, for all the DTE speed from 300bit/s to 115.2 Kbit/s. It is not usual to apply data compression on an ISDN network. For this reason a proprietary V42bis protocol was developed in accordance with the V.120 asynchronous mode. 1.4.3. Autologon It is possible to associate a list of options to the stored phone numbers, that enables specific procedures (ex: call with security password). These procedures allow authorised access to the system. The sequence consists of a number of transmitted and received fields, that are limited only by the buffer size (70 chars). 9 2. OPERATING DESCRIPTION 2.1. PACKAGE Make sure that the package contains all the following items: # Operating manual # A 3.5" disk containing the user guide & CCM.EXE enabler software # An ISDN cable with 2 RJ45 connectors at each end to connect the terminal adapter to the ISDN network 2.2. MECHANICAL INSTALLATION Insert the CCITA in the PC's PCMCIA slot, connect the external line adapter to the CCITA and power on the PC. 2.2.1. How to use CCM.EXE configuration program If the PC provides the drivers to manage the PCMCIA slots (Socket Services and Card services), refer to your PC's operating manual in order to use these drivers with the CCITA. In the event that the PC doesen't provide the drivers you will need to use the CCM configuration program on this disk. The CCM configuration disk contains two files: README.1ST CCM.EXE The README file is a quick guide explaining how to use the CCM.EXE configuration program. The CCM.EXE file is the software to configure the terminal adapter. Starting from the DOS prompt type CCM <ENTER>, without parameters, a list of commands, to be used with the program, will be displayed on the screen.

In order for this feature to work, both the originator and the receiver TA must have their CALLER ID feature enabled. Enabling the CALLER ID at the originator, allows the transmission of the originator's telephone number. Enabling the CALLER ID at the receiver, allows the caller's telephone number to be displayed on the receiver terminal. The message CALLER ID appears on the screen as follows: RING: nnnn where "nnnn" is the caller's telephone number *I0 CALLER ID function disable *I1 CALLER ID function enable To insert the CALLER ID number into the TA, please refer to the AT!N1 command. Store: S68 (bit 0) Default= *I0 *M MultiSubscriber Number function (MSN) The MultiSubscriber Number permits the association of maximum 8 consecutive numbers to a BRI access of the national plan number. There is a principal number with the last digit always equal to "0". Associated with it is an auxiliary number that may vary between "1" and "7". The called TA checks the incoming called party number with the number stored in its memory with the AT!N2 command; if the two numbers match then it answers the call, otherwise it does not. In order for this feature to work, the receiving TA must have its MSN feature enabled. *M0 MultiSubscriber number function disable *M1 MultiSubscriber number function enable To insert the MultiSubscriber number into the TA, please refer to the AT!N2 command. Store: S69 (bit 1) Default=*M0 20 *S Subaddress function The Subaddressing mode allows identification of 8 TA connected to the same BRI interface for the multinumber. This feature is managed only by the local and remote TA. The ISDN network only allows for the delivery of the subaddress field. The called TA sends telephone number followed the Subaddress field (ATDnnn+sss where "nnn" is the telephone number and "sss" is the Subaddress field with a maximum of 4 alphanumeric characters) the calling TA compares the received Subaddress to the stored Subaddress. If there's a match then it answer the call, otherwise it does not. In order for this feature to work, both the originator and the receiver TA must have their Subaddress features enabled. *S0 Subaddress function disable *S1 Subaddress function enable To insert the Subaddress field into the TA, please refer to the AT!N3 command.

AUTO-LOGON OPERATION The auto logon sequence is directly related to the TA phone number stored using &Z command. The auto logon sequence is executed either when the TA is in originate mode or in auto answer mode. The auto logon managment is based on the following control fields. Max number of characters is 35. The autologon sequence transmission is established by ^T command The autologon sequence reception is established by ^R command The AT command execution is established by ^C command To finish the auto-logon sequence press "ENTER" key. Example: Auto-logon sequence using security password. step command TA rensponse 1 AT&Z2=^T AT&Z2=<CR><LF>(Transmit) 2 Password?^R Password?<CR><LF>(Receive) 3 MONIQUE<CR> MONIQUE<CR><LF>OK Description 1 Start of the sequence, to be stored in the second memory location, containing the field transmission request. 2 The field to transmit is "Password?" followed by the receive field check command. 3 The field to check is "MONIQUE". The sequence is completed by <CR> (Return) command. The auto-logon sequence can start either with a transmission field or with a receive field check. For every receive field there is an associated a 30 second timer. When timer elapses, and the TA does not receive the expected message, the auto-logon sequence is stopped and the TA goes off-line and displays "AUTO-LOGON FAILED" message . To examine the contents of the auto-logon sequence stored in the memory location, type the AT&Zn? commmand, ( "n" is the number of the memory location). 33 2.7.1. Auto-Logon control character The auto-logon sequence can contain control characters in decimal or hexadecimal format. Description of the control characters. Character Description ^A Carriage Return. ^Xnn To insert an hexadecimal character. "nn" is the hexadecimal value of the character. ^P Pause. ^C Select the command field in order to allow the remote TA to execute an AT command sequence. Has to be inserted as the last character in the auto-logon sequence. ^T Select the transmission field. ^R Select the receive field. 34 2.8. HARDWARE OPTIONS Inside the external line interface of the CCITA, are two jumpers used to configure the impedence of the CCITA and in particular: ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ JUMPER POSITION DESCRIPTION ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ J2 Insert Receive Termination 100 ohm J2 Disconnected J3 Insert Transmit Termination 100 ohm J3 Disconnected ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ 35 3. DIAGNOSTICS This TA has an automatic internal self test diagnostic that commences automatically when the T.A. is turned on. 3.1. DIAGNOSTIC ACTIVATION If the CCITA is turned off and on, it automatically starts the internal self test diagnostics. During the automatic diagnostics, the LED on the external interface follows this sequence: RED -----> ORANGE -----> RED If the LED does not follow this color sequence, the T.A. probably has an internal fault. During the connection, the LED on the external interface follow this sequence: ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ COLOR STATUS ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ Red TA deactivated (Off Line status) Green TA activated (Off Line status) Orange TA in On Line mode ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ The activation/disactivation Terminal Adapter status, does not indicate any problems inside the TA. These sequences only allow you to enable/disable only Layer 1 connection procedures from ISDN network to the TA. 36 3.2. LOOP ACTIVATION On the CCITA, the diagnostic tests are activated using the AT commands from a terminal emulation progam. 3.2.1. Local Loop Activation With the T.A. in Off Line mode, send the AT&T1 command to enable the local loop test. To disable the local loop test send to the T.A. the escape sequence (+++) and the AT&T0 command. 3.2.2. Remote Loop Activation To activate this test, please follow these steps: # Make the connection with a remote T.A. # Set the escape sequence (+++) to the T.A. to go into command mode # Send the AT&T3 command to activate the remote loop test. All the data that you type passes through the ISDN network, to the remote T.A. interface and loops back to the local T.A. To disable the remote loop test send the escape sequence to the T.A. (+++) and the AT&T0 command. 37 digicorp Technical Support If you have any further problems or queries, please contact us at digicorp. tel.: +44 (0) 1372 844151 Email: Support@digicorp.co.ukDownload Driver Pack
