Note on the Relocate (Hoteling) Function
(see Section 9.11 "Relocate (Hoteling)")  
In systems with the U.S. feature E911 emergency service activated:  
 •   V3.0 SMR-7 and later: the Relocate feature guarantees that the LIN remains assigned to the physical port.
 •   V3.0 SMR-6 and earlier: you are not allowed to use the Relocate feature if the system has more than one Location Identification Number (LIN).

Definition  
The E911 expanded emergency call service makes it possible to transmit information about the physical location of a station in addition to the station number. Therefore not only the number of the station placing the call is available in the emergency call center, but the location too.
This requires that each subscriber line with a valid DID number be assigned a Location Identification Number LIN. The LIN is an unambiguous, max. 12-digit number that corresponds to the 10-digit NANP (North American Numbering Plan). Subscriber lines that are physically close to one another are given the same LIN. The emergency call center has a database that contains all the LINs and that uses the transmitted LIN to identify the name and address of the one placing the emergency call.
Danger  
Quick help after an emergency call is possible only when valid information concerning the location of the caller who is in trouble is available. For this reason, the correct assignment of the LINs to the available DID number must always be guaranteed.  
If the customer assumes the system administration, then the customer also assumes the responsibility for the correct assignment of the LINs. In this case, the customer must be informed that Siemens Enterprise Communications GmbH & Co. KG accepts no liability whatsoever for damages resulting from the improper use of this feature.  
V1.2 and later of HiPath 3000/5000 supports this feature for analog (loop start protocol) and digital trunks (Primary Rate Interface PRI).
