Chapter 2: Overview
The Teltone®Polling Controller and LSS (Line Sharing Switch or Substation
Line Sharing Switch) enable businesses and utilities having a single telephone
line or those using multiple telephone lines for data transfers to save costs
through line sharing.
Although the LSS can also be used as a standalone unit, providing a flexible,
cost-effective way to consolidate lines and route calls, Teltone strongly
recommends the use of a Polling Controller.
When working together, 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 and types of calls (e.g., outgoing
emergency calls from the substation take priority over polling calls).
Programming of options in the Polling Controller is done with a touchtone
telephone connected to the unit. The LSS can also be remotely programmed
through a touchtone telephone connected to the Polling Controller.
Figure 2 illustrates a typical application, in which a single telephone line is
shared by four devices: two modems, a fax machine receiving automatically
routed fax calls, and one telephone for incoming and outgoing calls.
The Polling Controller (Figure 2) is installed at the central polling location to
control how data calls are routed by the LSS.
Figure 2 Typical Application
Chapter 2: Overview
40-400-00013,Rev.C Page5

Basic Operation
The LSS answers incoming calls, determines the port to which the call should
be sent, 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. However, if no default port
is defined at the LSS, calls without transfer codes are disconnected.
The Polling Controller ensures that the transfer code is sent at the appropriate
time in the dial string. As a result, data calls are routed to the correct port at
the LSS every time, without guesswork about dial string progress. 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 ensures that a caller at the
LSS will get faster processing of the priority call.
A single Polling Controller can be used to call many LSS units.
The Polling Controller also translates the routing code supplied in the modem
dial string to either a factory set (i.e., unpublished and proprietary) transfer
code, or to a transfer code programmed by the system manager. The
unpublished and programmable transfer code provide added security to your
substation devices by hiding the remote modem from unauthorized access.
Polling Controller Reference Manual
Page 6

Chapter 3: Polling Controller Installation
As illustrated in Figure 2, the Polling Controller is installed at the location
from which you originate data calls to the LSS site, between the calling modem
and the telephone line. Use standard modular telephone cords for all line
connections (not supplied). The Polling Controller does not require any change
to your existing hardware.
Please refer to Chapter 2 for interface requirements for the Polling Controller.
Note: If lightning storms are common in your area, we recommend that you
install a surge protection device between the Polling Controller and the
incoming telephone line.

Chapter 3: Polling Controller Installation
40-400-00013,Rev.C Page7

Step 1: Connect telephone line
❑Connect a telephone line to the Polling Controller jack labeled “Telco Line”
using a standard modular cord (not supplied).
Step 2: Verify polarity of CO line wiring
❑Use a standard polarity tester to check the polarity. Polarity must be
correct on the wiring to the units to minimize relay contact wear and avoid
“bell tap,” a momentary or single ring of the telephone bell.
Caution: The unit should be powered down whenever you test polarity.
Step 3: Connect modem line
❑Connect the polling modem to the Polling Controller jack labeled Modem
using a standard modular cord (not supplied).
Step 4: Connect power
❑Connect the power cord to the Input Power jack on the Polling Controller
and the transformer to a non-switched, standard AC wall outlet.
Step 5: Test the installation
❑The Power/Status indicator should begin flashing. If it is not on, check that
the power cord is securely connected and that the outlet has power. If the
LED is on bright, but does not flash, call Technical Support for assistance.
❑After each LSS that will be polled by this unit has been installed, place a
call to each of its device ports and verify that the call is correctly routed. To
access the various LSS ports, refer to Table 3 to determine the routing code,
and enter a dialing string similar to the following:
ATDT4871515∗02
(With this dial string, the modem calls through the Polling Controller to LSS
Port 2. In this example, the LSS incoming line number is 487-1515.)
Installing Multiple Units in Carrier
The Polling Controller Carrier (model UM-112-801) is used for the installation
of up to eight M-390-A-04 Polling Controller units. See Figure 3. (The carrier is
available as an ordering option.) Follow the steps below to install the carrier
and Polling Controllers:
Step 1: Install carrier in rack
❑Figure 3 shows mounting brackets attached to the carrier in the position
required to center-mount the carrier in a 19-inch rack. If the carrier is to be
front-mounted, reposition the brackets as appropriate.
Polling Controller Reference Manual
Page 8

❑Attach the carrier to the rack frame using the screws provided.
Step 2: Make power and line connections to each unit
Complete the following steps for each Polling Controller to be installed:
❑Insert the unit in any of the eight slots (the slots are interchangeable), with
the power jack towards the bottom and the LED towards the top.
❑Connect power to each unit installed in the Carrier. (Eight power jacks are
available in the cable trough at the front of the carrier, below the card
slots.)
❑Connect a telephone line to the Polling Controller jack labeled “Telco Line”
using a standard modular cord (not supplied). Tag and label each line for
future reference.
❑Use a standard polarity tester to check the polarity. Polarity must be
correct on the wiring to the units to minimize relay contact wear and avoid
“bell tap,” a momentary or single ring of the telephone bell.
Caution: The unit should be powered down whenever you are testing polarity.

❑Connect the polling modem cable to the Polling Controller jack labeled
“Modem” using a standard modular cable (not supplied). Tag and label each
line for future reference.
Note: Cable runs are provided along both sides of the carrier so that cables
can be brought out to the back of the carrier.
Step 3: Connect wall power
❑Connect the carrier power cord to a non-switched, standard AC wall outlet.
Step 4:
❑The Power/Status indicators on the Polling Controller should begin
flashing. If they are not on, check that the power cord is securely connected
and that the outlet has power. If an LED is on bright, but does not flash,
please contact Technical Support for assistance.
❑Determine whether the LSS units that will be polled by the Polling
Controller have been programmed for your application. If not, this can be
done from your location using remote programming, as described in
Chapter 4.
❑After each LSS that will be polled by these units has been installed, place a
call to each of its device ports and verify that the call is correctly routed. To
access the various LSS ports, refer to Table 3 to determine the routing code,
and enter a dialing string like this:
ATDT4871515∗02
Note: With the above dial string, the modem calls through the Polling
Controller to LSS Port 2. In this example, the LSS incoming line number is
487-1515.
❑Test each LSS and Polling Controller.
❑When testing is complete, the unit is ready to go to work.

Chapter 4: Programming
Commands for programming the Polling Controller are listed in Table 2.
Cancel Command
To cancel all or part of a command, enter ∗in a command field. To cancel all
digits entered back to (but not including) the previous #, enter ∗in a data field.
To cancel the entire command, ∗∗ in a data field aborts the entire command. If
no data is entered in a field, that field is cleared.
Transfer Codes
Remember that all transfer codes must be the same length (i.e., contain the same
number of digits) and each code must be unique. The transfer codes can use
any of the 12 DTMF digits (0-9, *, and #).
Remote Programming the LSS
The LSS can be programmed remotely from the Polling Controller, if remote
programming has been enabled at the LSS. (The factory default is remote
programming enabled.)
Note: If you have not changed the Access Transfer Code for Remote
Programming, use Routing Digit #7 to access remote programming mode at
the LSS.
If the telephone connection is lost during programming or the LSS loses
power, the last completed command will have been saved, but any incomplete
command will be lost.
Setup Polling Controller for Programming
❑Disconnect the host modem and connect a DTMF telephone to the Modem
jack on the Polling Controller.
❑Go off-hook and enter # # within 15 seconds.
❑When you hear confirmation tone (3 beeps), begin programming. If you

Changing Transfer Codes
The table below lists the default routing code and the associated LSS ports. If
you wish to change the transfer codes from the proprietary (i.e., unpublished)
defaults, please record the new transfer code in the column on the right.
SLSS Users: While routing codes for 16 ports are listed below, the number of
ports in your application depends upon which model SLSS you are using: the
M-395-A has four ports and the M-396-A has eight.
Note: All transfer codes must have the same number of digits and must be
unique.
The routing code for ports 9 - 16 and the Port Groups are used for daisy-chain
applications only. If yours is not a daisy-chain application, disregard the
daisy-chaining information.
Note: If the LSS you are working with uses the routing codes *7-*0, continue
to use these routing codes. (These are the first four codes in the table.)
❑Fill in the Transfer Code column with the new entries. Plug a DTMF
telephone into the Modem port on the Polling Controller.
❑Pick up the telephone and press # #. Listen for beeps then enter the Port
Transfer Code command.
