March 15, 2000

Add Call Accounting Capabilities to

Nearly Any Phone System!

The CA-4 provides a cost effective way
to add call accounting features to any
phone system.

The CA-4 monitors up to four analog
telephone lines for inbound and
outbound call duration, time, date, and
number dialed.

The CA-4 buffers up to 1820 call records
for later retrieval. The data can be

formatted

formatted in ASCII delimited text to be downloaded to a PC via a RS-232 port. It can
also be output to a serial printer in a tabular format.

Installation

A. Lines and RS-232

The analog telephone lines should be
connected in parallel. Connect the
serial output of the CA-4 to a serial
printer or a PC using a 9 position RS­232 cable. The RS-232 connector is
configured as shown in the table below.

B. Clock Battery Back-Up

Battery back-up can be provided to maintain the clock operation. If
battery back-up is desired, remove the cover from the CA-4 and install a
9V battery onto the battery snap. Then remove the backing of the double
back tape on the inside of the cover and press the battery firmly to the
tape. The clock time will be maintained for approximately 24 hours.

Jumper 1

The CA-4 has a built-in charging circuit for rechargeable batteries. If a

9V Battery

standard battery is used, Jumper 1 must be removed before installing the
battery (see diagram at right) to disable the charging circuit.

Important: Serious damage may occur if the battery charging circuit is not
configured correctly. When using a rechargeable 9V battery, Jumper 1 should be in place. When using a non­rechargeable battery, Jumper 1 MUST be removed (see diagram above right).

Programming

A. Date and Time

1. Programming from a Touch Tone Phone

a. Call one of the telecom devices connected to the CA-4 using a Touch Tone phone.
b. When the telcom device answers, enter a ✱ and the security code “845464” (V-I-K-I-N-G).

Note: The security code can not be changed.

c. To change the time and date, enter two Touch Tone digits for each parameter.

min hours day month year

Example: 2:30pm March 9, 1998. Enter: 30 14 09 03 98

Note: You must use a leading “0” if the value is less than 2 digits.

d. When finished, hang-up.

2. Programming from a PC

a. Connect the serial port of the PC to the DATA port of the CA-4.
b. Establish serial communications (see section C. Setting Up Your Communications Software).
c. To change the time and date, enter two digits for each, in the following order: minutes, hours, date, month

and year. Press the <Enter> key to update the time and date.

Note: You must use a leading “0” if the value is less than 2 digits. If there is an invalid entry, “PROGRAM­ MING ERROR” will appear on the screen. Simply reenter the values and press the <Enter> key again.

d. Once the new programming values have been accepted by the CA-4, the new values will appear on the PC
screen.

B. Inbound DTMF Screening

The CA-4 does not monitor for ring voltage. The only method of determining whether a call is an “inbound” or
“outbound” call is the Touch Tones recorded. In certain situations Touch Tones may be entered on inbound calls,
such as when an Auto Attendant or voice mail system is called. To compensate for these applications, you may set
a maximum inbound Touch Tone filter. This filter will determine any call that uses fewer Touch Tones than the filter
setting to be “inbound.” All other calls will be labeled “outbound.”
