A Smart Line Sharing Device with
Inbound Switching Capability
Features
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
DE-
VICE 1
port will be disconnected for 2 seconds, re-
turning 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, Dis-
tinctive 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.
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 de-
vice must be capable of delaying this long before
dialing.
