Enhanced 911 (E911) configuration 363
Programming Operations Guide
• By default, Restriction Filter 02 is assigned to all sets on startup. There are no restrictions
applied in Restriction Filters 02-99. Restriction Filter 01 has restrictions, but 911 is an
exception for this filter. For information on how to change the Restrictions, refer to
“Defining
restriction filters” on page 356 .
• When using other trunk interfaces, you can assign separate line pools to groups of telephones
in different areas (for example, in different buildings, floors or sections).
• Be careful when using the Set Relocation feature. You may have to reprogram the line pool
access to send the right location on 911 calls.
• Configure the 911 destination code to dial out over a Normal Schedule in all applicable
Service Modes, as this is the default route should any other programmed routing attempts fail.
When using PRI interfaces, make sure all sets can use the PRI line pool that the Normal
Schedule route uses.
911 and IP telephones
DO NOT program IP telephones with a 911 code mapped to a line pool for the Business
Communications Manager, unless it is co-located with the system.
