LSD-2 is 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 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.
