In order to use Emergency Priority, program the last LSS in the chain for Emergency
Priority and all others for Total Priority. The last LSS in the chain will have priority over all
others in the chain. When an emergency call is made, the Total Priority mode of other
units up the chain will cause any call in progress to be terminated. As soon as dial tone
is received from the PSTN, the emergency call will be processed.

If you assign Total Priority to all LSS units in the chain, devices connected to ports on
the first and second LSS will be disconnected if any port on the last LSS goes off-hook.
Caution: If one of the LSS ports is in use when you go off-hook in either Total or
Emergency Priority Mode, the LSS will be unable to obtain network dial tone until the call
disconnects or until the times out (usually within 10-15 seconds).
If you assign No Priority to any of the LSS units, calls will never be interrupted. This
setting is not advised for applications requiring a telephone in emergency situations.

Programming for Daisy-chained LSS Units
Daisy-chained LSS units can be programmed either locally or remotely. After carefully
completing this section, follow the instructions in Chapter 4 or 5 to program the units.
Refer to the Table 5 for programming D applications.
Note: For reference only, Unit 1 is the first LSS in the daisy-chain, Unit 2 is the second,
