Chapter 2: Overview/Chapter 3: TL500A 2.0 General Operation
2. Overview
The TL500A can be easily tailored to fit the needs of individual organizations or
departments. A wide variety of remote site information systems can be accessed,
and with its register programs, the system functions can be configured to meet
the specifications of both calling and receiving modems and long distance
switching time. By using programmable security codes (up to seven digits),
35 million possible combinations of codes prevent unauthorized access to the
data devices.
3. TL500A 2.0 General Operation
The TL500A's routing function is based on DTMF tone detection. When a call is
placed to the remote location, the TL500A detects the phone company's ringing
voltage, goes off hook (answers), and begins a preliminary screening process.
During this time, the TL500A is looking for CNG and DTMF tone-based routing
instructions. For instance, if the TL500A hears the industry standard CNG tone
generated by a calling fax, the call is immediately and automatically routed to the
connected fax machine without disturbing the receiving party, ringing attached
phones, or
ringing other attached devices.
Each device port of the TL500A has its own DTMF security code that can be used
to protect any devices connected to the ports from unauthorized access. Each
separate security code can be programmed to any number up to seven digits,
including the * and # characters found on the telephone key pad. During an
incoming call, if the TL500A detects the DTMF access code for a device port, the
call is automatically routed to the correct device.
In the absence of fax tones or security codes, the TL500A begins to ring
the call through to its default port (Device 1).
Outgoing calls can be placed from any device port as if it were attached to a
dedicated line. Only one device at a time can actively use the telephone line.
When the line is in use by one device, other devices attempting to access the line
for an outgoing call will receive a busy signal. With special programming, this
feature can be overridden in an emergency situation where an outgoing call must
be placed quickly. (Reference Register 07 & 08 on page 11).
7-Segment Display— Displays the number of the Device Port in use or being
addressed. Also will display register values when reading values from memory.

Chapter 4: TL500A Program Registers
4. TL500A Program Registers
The TL500A has been designed to perform several operations that are integral to
the proper function of your total communications system. The operations are
controlled by programmable information that is stored in files called “registers.”
Each register contains enough memory to hold factory preset default values
and “custom” values that allow the TL500A to operate to your specifications.
The following is a short description of each register function, program capacity,
and factory preset default values.
REGISTER 01 — Mode Flags
This register controls eight features or operating modes performed by the
TL500A. Each “flag” or feature can be turned on/off and is programmed as a
string of bit information. Zero (0) denotes “off” and one (1) denotes “on.”
NOTE: When programming this register, you must enter all Flag (Bit) values.
The Mode Flags are factory preset to the following:
Register 01 — Mode Flags
Flag
Function
Value
Description
Flag 1 (Bit 7) Caller ID Store and
Forward
1 (on)
CID will be captured when unit
answers. CID data will be sent
one time, after the first ring,
when a device port is
addressed.
Flag 2 (Bit 6) Fax Tone Detect to
Device 2
1 (on)
If fax tone is detected, call will
be transferred to device 2.
Flag 3 (Bit 5) Night Watch Mode 0 (off)
Allows calls to automatically be
transferred to the specified
port if not answered within a
certain number of rings.
Flag 4 (Bit 4) Additional Detect
Time
0 (off)
0 (off)
Increases the time in which
tones can be detected before
ringing the default port by 4
seconds.
Flag 5 (Bit 3) Protected Hook
