A Smart Line Sharing Device with
Inbound Switching Capability
Why pay for a dedicated line for your elevator/emergency
phone or alarm panel?
The LSD-2 Line Sharing Device allows the user to share an
existing phone line with an emergency phone or other prior-
ity alarm device. This can save hundreds of dollars a year
over leasing a dedicated phone line. The LSD-2 can be used
on any C.O. line or analog PABX/KSU station.
An outbound call on the DEVICE 2 (PRIORITY) port takes
priority over a call in progress on the DEVICE 1 port. Any
call in progress on the DEVICE 1 port will be disconnected
for 2 seconds, returning dial tone to the DEVICE 2 (PRIOR-
ITY) port. A busy signal is then sent to the DEVICE 1 port.
For incoming calls, the LSD-2 can route calls to the DEVICE 2 (PRIORITY) port using Caller ID,
Distinctive Ring, or Quick Call Back. All other calls will be routed to the DEVICE 1. Alternatively, the LSD-
2can be set up so that all inbound calls are routed to the DEVICE 2 (PRIORITY) port. Note: Caller ID
is not passed through the LSD-2 to the devices.
Important: When the emergency device is in use, the phone line is not available for normal use. Any additional
emergency calls will have to be made on another phone line. For this reason the LSD-2 is not recommended for
single line applications. Note: With some Central Office equipment, it may take up to 20 seconds to disconnect an
incoming call to the non-priority device. The emergency device must be capable of delaying this long before dialing.

IN DEVICE 1 DEVICE 2 (PRIORITY)
A. Call Back Mode
To place the LSD-2 in Call Back Mode, move DIP switch 1to the ON position.
B. Distinctive Ring Mode
To use the Distinctive Ring Mode, first purchase distinctive ringing service from your local phone service provider.
Then move DIP switch 2to the ON position. Note: In this mode the LSD-2 detects double or triple custom ringing.
C. Caller ID Mode
Step 1. Move DIP switch 3 to the ON position.
Step 2. Call into the LSD-2, if a Caller ID is received that is not stored in the unit, the LSD-2 Status LED will go into
a fast flash mode.
Step 3. While the LED is flashing fast, push the SET button. This will store the new Caller ID number into memory
and re-ring the DEVICE 2 (PRIORITY) port.
Note: If more than 12 numbers are attempted to be stored, the LSD-2 will re-ring the DEVICE 1 port. If
the Caller ID number is already stored in memory, the LED will not fast flash and the call will be automati-
cally routed to the DEVICE 2 (PRIORITY) port.
To clear out the Caller ID memory, press and hold the SET button while powering up the LSD-2. The
status LED will wink off showing that all 12 memory locations have been cleared.
If all of the switches are in the OFF position, all inbound calls are routed to the DEVICE 2 (PRIORITY) port. Once any of
the DIP switches are turned on, inbound calls default to the DEVICE 1 port unless the selected method is detected by the
LSD-2. The LSD-2 can use three different methods to determine if an incoming call is to be switched to the DEVICE 2 (PRI-
ORITY) port, instead of defaulting to the DEVICE 1 port. Each of these methods can be switched on or off using the DIP
switches located on the front edge of the board. When mixing modes of operation, the LSD-2 uses all the modes that are
turned on, and if any of the selected triggers are detected, the incoming call will be routed to the DEVICE 2 (PRIORITY)
port. If a selected trigger(s) is not detected, the inbound call will ring through to the DEVICE 1 port. For more information
on these modes, see Operation section C.
Note: To force all calls to be routed to the DEVICE 1 port, simply set DIP switch 3 to the ON position, but do not program
any caller ID numbers.
D. Disconnect Time
The length of time that the LSD-2 disconnects the DEVICE 1 port before gaining fresh dial tone for a DEVICE 2 (PRI-
ORITY) call, is factory set to 2 seconds. If this is not enough time for the line to return fresh dial tone, the LSD-2 can
be programmed to delay anywhere from 1 to 20 seconds.
Step 1. With the LSD-2 sitting in idle state, momentarily press the SET button and wait for the STATUS LED to blink the
current disconnect time in seconds. If the STATUS LED blinks twice, the disconnect time is set to 2 seconds.
Step 2. The STATUS LED remains off for approximately four seconds, during this time you may press the SET button once for
each second of disconnect time required (Example: five times for 5 seconds). The LSD-2 will confirm by blinking the
new disconnect time on the STATUS LED. If the LED flashes fast, the maximum setting has been exceeded.
Important: Be sure that the auto-dialing device on the DEVICE 2 (PRIORITY) port can be programmed to provide a
longer delay time than the LSD-2’s disconnect time. This assures that the auto-dialing device waits until there is fresh
dial tone before dialing.

Caller ID switching relies on Caller ID services provided by your local telephone company. Any number pro-
grammed into one of the 12 Caller ID memory positions will be automatically routed to the DEVICE 2 (PRIORITY)
port (see Programming section C).
3. Caller ID Mode (switch 3 ON)
If a priority device, such as an emergency phone, is sharing a line with an “outbound only” device, such as a cred-
it card reader, or “outbound only” trunk, set all switches OFF and all inbound calls will be routed to the DEVICE 2
(PRIORITY) port.
4. All Inbound Calls Routed to the DEVICE 2 (PRIORITY) Port
If all inbound calls are to be routed to the DEVICE 1 port, set DIP switches 1& 2 OFF and 3to the ON position, but
do not program any caller ID numbers.
5. All Inbound Calls Routed to the DEVICE 1 Port

A. LED Status
B. Outbound Calls
When the LSD-2 is idle, the Status LED will be lit solid, and both ports are connected to an internally generated 35V
DC talk battery. If a device attached to the DEVICE 1 port goes off-hook, the phone line will be switched to the DEVICE
1port. If the device attached to the DEVICE 2 (PRIORITY) port goes off-hook, the phone line will be switched to the
DEVICE 2 (PRIORITY) port. If the device attached to the DEVICE 2 (PRIORITY) port goes off-hook while a call is in
progress on the DEVICE 1 port, both ports will be switched away from the phone line for two seconds (programmable
from 1-10 seconds), simulating a two second hang-up. The LSD-2 then reconnects the DEVICE 2 (PRIORITY) port to
the phone line. The device attached to the DEVICE 2 (PRIORITY) port receives fresh dial tone and is now able to dial
out. While the DEVICE 2 (PRIORITY) port is in use, a simulated busy tone is generated to any device attempting to
go off-hook on the DEVICE 1 port.
C. Inbound Calls
To use the Quick Call Back mode, call into the LSD-2 from another phone line, listen for a single ring back tone and
hang-up. Wait 6 seconds, then call back to the LSD-2 (within 20 seconds). The LSD-2 will route the incoming call
to the DEVICE 2 (PRIORITY) port instead of defaulting to the DEVICE 1 port (see Programming section A).
1. Quick Call Back Mode (switch 1 ON)
Custom Ring switching relies on “Distinctive” or “Custom Ring” services provided by your local telephone compa-
ny. Any call with a custom ring cadence will be routed to the DEVICE 2 (PRIORITY) port. Inbound calls with stan-
dard ring cadence will be routed to the DEVICE 1 port. The LSD-2 accepts both double and triple custom ring
cadences as custom (see Programming section B).
