2.16.1. Important Information / Restrictions 
- IPDA If the function IPDA (HG3570) is configured on an STMI board, the IP address of the common gateway must be assigned with the AMO BCSU. For all other functions of the board, the IP address must be assigned with the AMO CGWB.
- IPDA If several functions are defined in a function block (IPDA and others), the IP address for IPDA must be set with AMO BCSU, for the other functions the same IP address must be configured using the AMO CGWB!
- VLAN settings in AMO CGWB: When MFS is configured, the following
AMOs are used:
- MFS with IPDA functionality: AMO SIPCO
- MFS without IPDA functionality: AMO CGWB
- Trunking protocols Only one trunking protocol can be configured for each common gateway board (either SIP or H323)! If both protocols should be used for trunking, individual boards must be used.
- IPDA/WAML No support of WAML and HG3570 (IPDA) functionality on one common gateway board because it causes path problems at APNW access points.
