5.16.3.2. Service Information 
- For the Internal Reroute function, the parameter REROUT in AMO RICHT need not necessarily be set to the value "Yes".
- No circuit is seized in the case of Internal Rerouting, i.e. the LCR remains within the system.
- The parameter TGRP in AMO LDAT should be completed using a TIE Trunk if LATTR=RERTEINT is set. The Trunk will not be seized or permissions checked, but a TIE Trunk instead of CO is important for some DB procedures.
- Routing to the own system no longer functions if the own destination node number is specified in the route.
- Incoming channel search for IP Trunking is not supported and does not work when only LDAT entries are available with RERTEINT.
Notes on LATTR=RERTEINT
- RERTEINT was developed only to reach an internal destination after dialling a number e.g. the E.164 ISDN CO code for the local switch.
- RERTEINT should not be used to reach any external destinations (i.e. the result after RERTEINT should physically belong to the local switch).
- It is coincidental RERTEINT is allowed for basic call (i.e. to reach an external destination).
