X25 ACCESS POINT
Access_points are automatically created when the DataBase is built for the following applications : Incident, system management, accounting and monitoring IP TUNNEL traffic ; they cannot be deleted. It is possible to create (and delete) some other access points.

Port IPC/TEI
The access points are created with section "operational" devalidated.
Depending on the case, it designates :

This number is between 0 and 255 inclusive.

Operational
This section is used to provisionally deactivate the access point.
YES : LLP parameters of this access point are activated ; therefore they are not accessible in modification or deletion mode.
NO : this access point is not operational. The modifications or deletions are therefore possible:
Version 1.3/1.4:

Version 5:

X25 Address
This section is used for S0, S0-UA, V120 DTE access point types and applications.

Number Packet Network
This section is used for T0 and T2 type accesses.
It defines the packet network of the link.

X25 Profile Id
This section is used for all access point types.
The profile number (0 to 63) corresponds to a table (see X25 PROFILE) containing the X25 profile (logical paths, throughput, window size, packet ...).

Layer2 Profil Index
The layer 2 profile allows the link frame parameters to be adjusted. The index gives the layer 2 profile number which will be applied on the link.

Format X25.84
This section is used for the format of the packets delivered to terminals and gateways.
YES : use of X25.84 formats and subsequent ones.
NO : use of formats previous to X25.84.
If you do not enable, the following features are forbidden:


Fast Select Acceptance
This section is used for terminals and gateways.
Fast selection is a complementary X25 service.
The fast select accept attribute has a meaning (can be set to true) only if the X25 format basic attribute is False.
YES : the fast selection service is used.

Barred Incoming Calls
This section is used for all S0, S0-UA, V120 DTE access point types and application.
YES : the PABX releases the calls that it receives destined for the "terminal" (Terminal not authorized to receive calls).

Barred Outgoing Calls
This section is used for all S0, S0-UA, V120 DTE access point types and application.
YES : the PABX prohibits the call packets presented by the "terminal" (Terminal not authorized to transmit calls).

Flow Control Negotiation
This section is used for terminals and gateways access points. Access is possible if "format X25.84" is on YES.
YES: the flow control parameters negotiation is used: window size and packet length are negotiated.

Throughput Class Negot.
This section is used for all terminals and gateways access point types, except application and T0.
YES : the throughput class is negotiated.
This service is used only if "format X25.84" is on YES.

Removed By Network
This section only appears in modification mode.
NO: normal position.
YES: the link is not known by network; the manager must call public administration (Subscription problem), and take again in position NO when the problem is settled.

Keep Called Adr
YES: the called address is kept in the incoming call packets sent to terminals.

Implicit Activation Mode
The priority activation mode defines the way in which the preemption privilege is applied to the current call.
Priority activation mode by default:


Implicit Priority
Implicit priority (level, activation mode) is the default priority for the call (when no explicit operation for request of priority has been made).
The priority level fixes the rights of the call with respect to the preemption privilege. An unprotected call can only be preempted by a call with a higher priority level.
Priority level by default between 0 (min. priority) and 15 (max. priority).

Explicit Priority Right

Indicates if the user has right to express his explicit priority.



Explicit Activation Mode
The priority activation mode defines the way in which the preemption privilege is applied to the current call.
Maximum activation mode applicable following the subscriber's explicit request:


Explicit Priority
The explicit priority (level, activation mode) is the one which is applied to the call when the terminal makes an explicit request for priority (either by the priority CUG, or in the call packet by using the non-standardized priority facility).
The priority level fixes the rights of the call with respect to the preemption privilege. An unprotected call can only be preempted by a call with a higher priority level.
Priority level applicable following the subscriber's explicit request: between 0 (min priority) and 15 (max priority).

Priority Presentation
This attribute states whether the subscriber manages the priority facility and, if necessary, asks the Packet Handler to withdraw this facility from the call packet before it is presented to the terminal.
YES: the subscriber manages the priority facility.

Call Rerouting Right
Call rerouting is a complementary service offered to DTEs in the private X25 network. It enables call forwarding to the same destination, either systematically or when the subscriber is busy or out of order. To use this service, this parameter must be set to Yes.
YES: the subscriber is allowed systematic forwarding.

Call Bypass Right
Call bypass right is a complementary service offered to DTE users in the private X25 network. It enables call forwarding to the same destination selected by the DTE and supplied by it in the release packet which it returns following a received call packet.
YES: the subscriber is allowed call after call forwarding.

CUG Right
The Closed User Group is a complementary service which allows the subscribers who form a group to make calls between themselves while protecting themselves from accesses from the outside in the case where the access point is a gateway.
When the access point is a gateway, this parameter corresponds to implementing a service for transcoding the CUG values.
YES: right to CUG (Closed User Group).

CUG Profile Id
The CUG profile defines the application of the CUG service. The parameter give as reference the CUG profile number which will be used to implement the service.
Profiles:
Not used for DTEs.


Rerouting Or Moved Subscr.Addr.
Modification mode.
X25 address of the terminal to which the call will be forwarded, if the Call Rerouting Right is set to YES.

Number Of PVC
Each DTE can contain up to 10 PVCs (Permanent Virtual Circuit). The maximum number of PVCs that it can contain must be indicated for each DTE.

Lg Max Calling Addr
(15 is the default value).
Calling number maximum length allowed when going out towards a network, when the called address is not in format X121:
Transpac:6

Lg Max X121 Calling Addr
Calling number maximum length allowed when going out towards a network , when the called address is in format X121:
Transpac:2

Called Addr In Call Con
This parameter is used when the access point is a gateway. It allows authorization of the called address in the call connected packets.
Transpac: NO

Called Addr.Modif.Notif.Facility
The called address modification notification facility (CAMNF) is used in X25 networks to perform complementary forwarding services (systematic or call by call). Some networks do not accept this facility.
The parameter is used when the access point is a gateway
YES: facility allowed in the call confirmed packet.

PNIA Address
Not used

Systematic Rerouting
The subscriber must have the call rerouting rights.
Systematic rerouting is a complementary service offerred to DTE users in the private X25 network. It enables systematic forwarding of all the calls to the same destination
YES: enables systematic call forwarding for a terminal. The calls will be sent systematically to the address specified in the rerouting address attribute.

External Rerouting on Transit
Some networks cannot completely handle the facilities which allow call forwarding (systematic or call by call).
This parameter is used when the access point is a gateway. It allows call forwarding to a subscriber in the external network to be forbidden at gateway level.
Transpac: NO

Reverse Charging Acceptance
In the case of a call with reverse charging complementary service packet:


PSPDN Subscription Number Value
This attribute should be filled in if the attribute PSPDN Subscription Number Insertion is set to YES.
The value is given by the public carrier.

Overbook Coefficient
Coefficient of overbook in level 2 (LLP or LCC). This coefficient is a multiplication factor: the total level 2 flow is equal to the flow of the profile multiplied by this coefficient.
See - X25 SYSTEM PARAMETERS - Overbook.

NMC Presence
This section concerns the physical addressing by IP/X25 tunnel for the NMC management machines connected over an 4400. The physical addressing is used to identify which is the caller (see the attribute NMC Identity).
YES: presence of an NMC management system (47xx).

NMC Identity
This section identifies the type of NMC terminal:


Ext Network Access List for TE
When a terminal wants to access an X25 packet network:
YES: the routing of X25 communications to external networks is authorized via predetermined gateways (see External Network Access List).

Extern Network Access List
This list contains the predetermined gateways used by the terminal to route X25 communications to external networks (see the attribute External Network Access List for TE).
