NETWORK OPERATION
In a network, if only one phone is off-hook it is automatically “connected” to the circuit, receives a
local dial tone, and is able to place a call. The dial tone will remain until any key is pressed. A dial
tone will not be present if more than one phone is “connected” to the network.
Phones that go off-hook to answer a call will also become “connected” to the network. For a
conference call, all current parties remain “connected”, and calls can be made to other stations.
However, the period between calls must exceed five seconds. If more than one phone is “connected”,
a local ring-back tone will not be heard if “Group” or “All” call is initiated. A ring back will be heard
by all “connected” parties if a “Unique” call is placed, and will remain until the phone is answered or
the number of ring attempts at the called phone is qualified.
If a phone goes off-hook to place a call, but does not receive a dial tone, the network is busy. A local
busy-tone may or may not be present, depending on the “Busy Circuit” setting described below.
Each station in a network can belong to one of nine “Groups”. A “Group” can be called by dialing the
“Group” number followed by the “*”. Only the phones at stations having the same “Group” number
(0-8) will ring for a pre-programmed number of times. Ringing at each station will cease when the
phone goes off-hook, or the number of ring attempts is qualified. Phones already in the off-hook
condition will not ring. The phone that dialed the “Group” will receive a local ring back tone until any
other phone in the network is “connected”.
A user can call “All” stations by dialing a “*”. This will cause all phones in the network to ring for a
pre-programmed number of times. Ringing will cease when any phone goes off-hook, or the number
of ring attempts is qualified. Phones already in the off-hook condition will not ring. The phone that
dialed “All” stations will receive a local ring back tone until any other phone in the network is
“connected”.
A user can call a “Unique” Station by dialing a 3-digit station ID within five seconds of one another.
The phone at the “Unique” station will ring for a pre-programmed number of times. The ringing will
cease if the receiving party goes off-hook, the calling party goes on-hook, or the number of ring
attempts is qualified. The receiving phone will not ring if it was previously in the off-hook condition.
The phone that dialed the “Unique“ station, and any other connected phones will receive a ring back
tone generated by the phone that was called. The tone will disappear once the “Unique” station goes
off-hook, or the number of ring attempts has been qualified.
A 50-second timeout will release the circuit if a phone is inadvertently left off-hook. A local re-order
tone will be heard to indicate a timeout. A phone selectively calling (Unique call) a phone that timed
out, will also receive a re-order tone. A phone that has timed out must be placed on-hook to be back in
service.
