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

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).

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.

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:

2.7. 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.

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.
