LSD-2 Smart Phone Line Sharing Device w/ Inbound Switching

LSD-2 is A Smart Phone 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 priority 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 (PRIORITY) 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-
2 can 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.

 Share an existing phone line with an emergency
device such as:
• Emergency phones
• Area of refuge phones
• Alarm panels
• ATM's
• Card readers
• Any device that needs instant access to a
phone line


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
