10.26.3.2.3. Call Handling and Networking 
A E911 Emergency number must be configured in AMO WABE .
In LCR the routes over which an E911 emergency call are to be routed
are specially marked as emergency routes. Special outdial rules for the
E911 switching have to be configured to take into account both ISDN and
Analog connections
In AMO BUEND it is possible to mark lines or B channels as reserved
for the E911 connections.
Connections via Analog or Digital require COT Parameters to Filter
or release Information which are transmited over the analog line or
digital Protocoll.
Special care has to be taken when networking that both partners "understand"
each other regarding the transmission of information. The parameters
must be co-ordinated on both sides for outgoing and incoming connections
(e.g. analog to analog)..
