Line Sharing Switch
Chapter 2: Overview
The Teltone Polling Controller and LSSenable businesses using multiple dedicated
telephone lines for short-duration data transfers to save costs through line sharing. In
companies where headquarters regularly poll branch offices for data collection, the
system allows devices, such as modems, to share a phone line at the remote location.
The LSS can also be used by itself, as a standalone unit giving you a flexible,
cost-effective way to consolidate lines.When operating as a standalone unit, calls to the
LSS are routed to the device port without a Polling Controller.
Figure 1 illustrates a typical system application, in which a single telephone line is shared
by four devices: a fax machine receiving automatically routed fax calls, a polled Point of
Sale (POS) server receiving incoming calls, one credit authorization terminal making
outgoing calls, and one telephone for incoming and outgoing calls.
Components
For maximum effectiveness, the Polling Controller and LSS should be used as a system.
The Polling Controller is installed at the central polling location to control access to the
line at the LSS.The LSS is located at the business where lines are being consolidated.
Three versions are available, enabling connection of two, three, or four devices.
The two units communicate across the public switched telephone network (PSTN) to set
up and disconnect calls as well as to determine priorities among devices.
Standalone LSS
If you select this option, the LSS can be used without a Polling Controller to route calls
using standard DTMF codes.Although not required, a Polling Controller is recommended
for data polling applications.

Figure 1 Typical Application
Reference Manual Chapter 2: Overview
Programming
LSS options are programmed with a DTMF telephone, either locally or remotely from a
Polling Controller.
Compatibility
Any device that can be connected to a standard loop start telephone line, including
telephones, modems, point-of-sale terminals, credit/debit authorization terminals, fax
machines, voice mail systems, answering machines, and others, are compatible with the
Teltone Polling System.These types of telephone lines are also known as Analog Line,
POTS (plain old telephone service) lines, and Single Line Telephone circuits.The LSS will
not operate on digital lines or ground start trunk circuits. The LSS will ring up to five (5)
telephones connected to any single device port.
Note:

telephone matches one of the ten emergency numbers. For example, if you need to
dial 9-1-1, but the line is being used by the fax machine on Port 2, dial 9-1-1 and your
call will be sent through.
q

times out (usually within 10-15
This option enables you to route fax calls to a specific LSS port when the LSS detects a
faxing tone.
Remote Programming Access
This option enables you to program the LSS from a remote site.
Programmable Default Port
This option gives you the ability to change the default port to which a call is routed when
no transfer code is provided.This enables you to customize the default ports to match
your application or you can use this feature to prevent default routing.
40-400-00015, Rev. F Page3
Line Sharing Switch
Programmable Transfer Codes
This group of features improves security by allowing you to specify the DTMF tones which
route calls at the LSS, ensuring that calls are transferred to the appropriate port. Transfer
codes can be programmed so that the LSS can be used with and without a Polling
Controller in the same application.
Privacy Timeout
When someone takes the telephone off-hook to block incoming telephone calls or when a
device (modem or fax machine) is stuck in an off-hook position, the resulting busy line
prevents incoming calls to all ports.With Privacy Timeout, the LSS will be able to answer
calls and route them to any port, except for the line that is off-hook.
Basic Operation
The LSS answers incoming calls, determines the destination, and routes the call.If a
transfer code is received from a Polling Controller, the LSS routes the call to the
requested device, such as a polled modem.If no transfer code is received, the call is
routed to the default port (Port 1 is the factory default), usually connected to a telephone
(or a telephone and extensions).
When the LSS is used without a Polling Controller, the caller must be sure the LSS
answers the call before sending transfer codes to route the call to a specific port.
An advantage of using the Polling Controller is that the user does not need to generate
the pause time in the dial string between the telephone number and routing code to
accommodate variable switching delays in the network.In addition, the Polling Controller
will hang-up polling calls at the originating end when a priority outbound call is initiated at
the LSS.This latter point means that a caller at the LSS will get faster processing of the
priority call.

Teltone recommends the use of a standard polarity tester such as Radio Shack
q
43-101. Polarity must be correct on the wiring to the units to minimize relay contact
wear and avoid “bell tap” (a momentary or single ring at the telephone).
Caution: Make sure that the unit is powered down before using the tester.
Plug the tester into the Port 1 jack on the rear panel of the LSS.
q
Check for the following conditions:
If the green light on the tester comes on, the polarity of the wiring is correct.
q
If the red light comes on, Tip and Ring are reversed and must be swapped.

Installation on PBX or Key Telephone Systems
The LSS can be installed on the telephone company central office side, or trunk side, of a
PBX or Key Telephone System.The LSS can also be installed on the station side or as
an extension on a PBX or Key Telephone System, as long as the interface in an analog
loop start circuit.
For best results in trunk installation, install the LSS in series with the lowest priority
incoming line in a PBX or Key Telephone System hunt group.
Calls intended for devices attached to the LSS must be dialed directly to the telephone
number for this line to prevent misdirected polling or FAX calls.
