Figure 14 “Configuring a “networked“ access point” shows the fundamental information required for configuring a “networked“ access point
  • The fact that the access point is linked via router with the OpenScape 4000 LAN segment: Link type APNW, i.e. “networked“.
  • The LTU number of the access point, i.e. 99.
  • The LTU part number specifies the HG 3575 used.
  • The access point’s shelf type is derived from the type designation.
  • The IP address of the access point: 192.168.23.99.
  • The IP address for the TAP/Service PC link at the access point: 192.168.23.199.
  • The IP address of the router (port), via which AP99 accesses the OpenScape 4000 LAN segment: 192.168.23.1.
  • The netmask in the segment of the AP99: 255.255.255.0.
  • The IP address of the router (port) at the OpenScape 4000 LAN segment, via which the AP99 can be accessed by the central components in the OpenScape 4000 LAN segment, i.e. in this case: 192.168.1.254.
  • By limiting the number of B-channels, the bandwidth available to AP99 is indirectly reduced in the configuration example. This mechanism works independently of the bandwidth limitation performed by the Resource Manager in the “Large Enterprise Gatekeeper” Feature. For further information, please refer to Chapter 3, “Load Calculation”.
  • Should Payload Quality Handling be activated? For details see Section 2.9, “Payload Survivability”.
  • The Source Group Index is explained in detail in Section 2.8, “Source Dependent Routing”.
Additional data is explained in more detail with the corresponding AMO parameters.

Generation

An access point is configured with three AMOs (UCSU, APRT, STMIB) and activated with USSU.

UCSU

With the AMO UCSU, the access point is configured as a new shelf in the system and its reachability via routers is ensured.

STANDOID
d
Standort Identifikation
Schlüsselzahl zur Identifikation des Standorts eines Access Points, der unterschiedlich zum Standort der Zentralanlage sein kann. Der Parameter wird benötigt, um den vertrieblichen Bestand (PARK-Daten) der Anlagenteile standortabhängig zu pflegen. Der Wert wird vom Konfigurator-Tool vergeben und muss so übernommen werden. Gegebenenfalls ist der Wert vom Systemplaner zu erfragen. Ist kein Tool-generierter Wert verfügbar, z.B. bei Teststellungen, soll der Wert 999 verwendet werden, um dies auszudrücken. Bei Erweiterungen an einem Standort (zusätzlicher Access Point) kann der Wert des bereits existierenden Access Points übernommen werden. Systemkomponenten in einem anderen Raum, Stockwerk, oder Gebäude werden unter einer anderen Standort-Identifikation geführt!
 
LOCID
e
Location Identification
Key number for identification of the location of an Access Point, which can differ from the location of the central switch. This parameter is necessary to maintain the sales database for the parts of the system, based on locations. The value is determined by the Configurator tool and must be taken over unchanged. If necessary, ask the system planner for the value. If no tool-generated value is available, e.g. for test and demo configurations, the value 999 shall be used to express this. For expansions at a certain location (additional Access Point), the value of the already exisiting Access Point can be taken. System components in another room, floor or building are listed under a different location ID.

siehe Chapter 3, “Load Calculation”
 
BCHLCNT
e
B Channel Count
Defines how many B channels may be used concurrently at the interface between Access Point and LAN. By this the maximum bandwidth needed by an Access Point can be limited coarsely.

MASK=255.255.255.0;
IMPORTANT:
Prior to ADD-APRT, use ping to check that the IP addresses given to you by the administrator are reachable. APIPADDR must not respond, as this would indicate that the corresponding address had already been assigned. APIPADDR must be set differently for every access point. The AMO does not verify if this rule is observed.

With the AMO APRT, additional functions of an access point can be configured.

STMIB

Nothing special has to be configured with STMIB. The CHANGE branches allow a multitude of parameters to be set. Details are described in Section 2.2.3, “Changing Access Point Parameters with the AMO STMIB”.

USSU

In order to actually put the access point into operation after the configuration process, it has to be activated.
assistant-2.gif
Configuration Management > System Data > IPDA > IPDA System Data
Click Search and select the access point.
Click Execute on the Action pull-down menu
and set the mode of action Configure AP, confirm with OK.
comwin-2.gif
 
EXEC-USSU:MODE=CONFAP, LTU=xx;
From this moment on, the OpenScape 4000 CC attempts to reach the access point and, as soon it achieves this, to start it.
IMPORTANT:
Prior to EXEC-USSU:CONFAP, the configuration must be updated on the system hard disk, Otherwise, the data on the system would conflict with the data on the HG 3575 when the system is reloaded and could only be synchro­nized again with EXEC-USSU:UPDATAP,LTU number,UL.
In order to be able to reach the access point from the CC upon initial installation, various data has to be entered locally at the access point (see Section 2.2.5, “Local Configuration of an Access Point”).
