10.2. Configuring the IPDA Feature 
IP distributed architecture is rather a platform expansion than a
typical new feature. Therefore, the configuration of this feature is
broken down in the following section into typical steps, which are to
be performed in consecutive sequence:
- Configuration: OpenScape 4000 LAN segment - Section 2.1, “OpenScape 4000 LAN Segment”
- Configuration: Access Point (networked or direct link) - Section 2.2, “Access Point”
- Configuration: HG 3500 as HG 3570 - Section 2.3, “HG 3500 as HG3570 in the OpenScape 4000 System”
- Configuration: Subscriber, trunk and tie trunk connections in access points - Section 2.4, “Subscriber, CO/Tie Trunk Circuits in Access Points”
If necessary, the following steps are performed subsequently:
- Configuration: Special routes - Section 2.5, “Special Routes”
- Configuration: Signaling survivability - Section 2.6, “Signaling Survivability”
- Configuration: Quality monitoring for the signaling connection over IP - Section 2.7, “Quality Monitoring for the Signaling Connection over IP”
- Configuration: Source dependent routing - Section 2.8, “Source Dependent Routing”
- Configuration: Payload survivability - Section 2.9, “Payload Survivability”
- Signaling and payload separation - Section 2.10, “Signaling and Payload Separation (SPS)”
- Divert call in survivability mode to another access point - Section 2.11, “Divert Call in Survivability Mode to another Access Point”
- Configuration: External music on hold - Section 2.12, “External Music on Hold”
- Information on CMI - Section 2.13, “Information on CMI”
- Configuration: IP address changes - Section 2.14, “IP Address Changes”
-
These notes must be observed if the IP addresses in the OpenScape 4000 LAN segment are to be changed in an active system (for example, because the network carrier changes the network address).
- Configuration: a-law/µ-law conversion - Section 2.15, “A-Law/µ-Law Conversion in AP Shelf”
- Configuration: Different announcements, tones, DTMF dial tone receivers per access point - Section 2.16, “Different Announcements, Tones and DTMF DialTone Receivers per Access Point”
- Configuration: Different display languages/national character sets per access point - Section 2.17, “Different Languages/National Character Sets for Displaying Text for Individual Access Points”
The corresponding sections contain configuration examples and detailed
explanations of all requisite AMOs and AMO parameters. A distinction
is made between
 |
configuration with Configuration Manager and
|
 |
configuration with AMO.

The creation of the “Access point Emergency“ feature is described
in “Access Point Emergency (APE)”, Chapter 2,
“Configuring the APE Feature (Access Point Emergency)”.
