Abstract

A method for operation of a central office point of delivery includes: in response to a pluggable interface module being plugged into an access node port of a line termination node of the central office point of delivery, transmitting, by the line termination node, a request message to a control node of the central office point of delivery, wherein the request message comprises interface module information related to the pluggable interface module, and wherein an activation clearance is requested, via the request message, from the control node; receiving, by the line termination node, from the control node, an acknowledgement message related to the activation clearance requested by the request message, wherein the acknowledgement message corresponds to a verification operation and/or activation clearance operation having been successful; and activating, by the line termination node and/or by the access port node, the pluggable interface module.

First claim

1 . A method for operation of a central office point of delivery, wherein the method comprises:
in response to a pluggable interface module being plugged into an access node port of a line termination node of the central office point of delivery, transmitting, by the line termination node, a request message to a control node of the central office point of delivery, wherein the central office point of delivery comprises at least one control node and a plurality of line termination nodes, wherein each line termination node of the plurality of line termination nodes comprises a number of access node ports, wherein each access node port of the plurality of access node ports is configured to receive or be connected to one of a plurality of pluggable interface modules, wherein the request message comprises interface module information related to the pluggable interface module, and wherein an activation clearance is requested, via the request message, from the control node; receiving, by the line termination node, from the control node, an acknowledgement message related to the activation clearance requested by the request message, wherein the acknowledgement message corresponds to a verification operation and/or activation clearance operation having been successful; and activating, by the line termination node and/or by the access port node, the pluggable interface module.

2 . The method according to claim 1 , wherein the control node has access to a database entity of the central office point of delivery and/or of a broadband access network of a telecommunications network, and wherein the method further comprises:
after transmitting the request message and before receiving the acknowledgement message, transmitting, by the control node, a verification request message to the database entity, wherein the verification request message comprises at least part of the interface module information; after transmitting the verification request message and before receiving the acknowledgement message, performing, at the database entity, the verification operation and/or the activation clearance operation; after performing the verification operation and/or the activation clearance operation and before receiving the acknowledgement message, transmitting, by the database entity, a verification acknowledgement message to the control node, wherein the verification acknowledgement message comprises, in case that the verification operation and/or the activation clearance operation having been successful, acknowledgement information related to the pluggable interface module being permitted to be activated at the access node port; and after transmitting the verification acknowledgement message, forwarding, by the line termination node, the acknowledgement message related to the activation clearance requested by the request message.

3 . The method according to claim 1 , wherein the method further comprises:
after the pluggable interface module is plugged into the access node port and before transmitting the request message, transmitting, by the line termination node and/or by the access node port of the line termination node, an interface module discovery message to the pluggable interface module; and receiving, by the line termination node and/or the access node port of the line termination node, a discovery response message from the pluggable interface module, wherein the discovery response message comprises the interface module information related to the pluggable interface module.

4 . The method according to claim 2 , wherein the verification request message comprises a type verification request, wherein, via the type verification request, the database entity is queried for interface module type and/or identification information related to the pluggable interface module ( 301 ),
wherein the verification operation and/or the activation clearance operation having been successful is based on the database entity comprising interface module type and/or identification information related to the pluggable interface module.

5 . The method according to claim 4 , wherein in case that a driver module corresponding to the type of the pluggable interface module is not yet in use by the control node, the control node accesses such a driver module corresponding to the type of the pluggable interface module from a repository entity.

6 . The method according to claim 2 , wherein, as part of performing the verification operation and/or the activation clearance operation, a type verification and/or a topology verification is performed by the database entity, wherein the verification operation and/or the activation clearance operation is successful based on the pluggable interface module fitting the access node port of the line termination node and/or a network topology property corresponding to the access node port of the specific line termination node.

7 . The method according to claim 1 , wherein the plurality of line termination nodes are part of a switching fabric or connected to the switching fabric, wherein the switching fabric is part of a broadband access network of telecommunications network, and wherein the switching fabric comprises a plurality of spine network nodes and a plurality of leaf network nodes.

8 . A telecommunications network for operation of a central office point of delivery, wherein the telecommunications network comprises:
the central office point of delivery, wherein the central office point of delivery comprises at least one control node and a plurality of line termination nodes wherein each line termination node of the plurality of line termination nodes comprises a number of access node ports, wherein each access node port of the plurality of line termination nodes is configured to receive or to-be connected to one of a plurality of pluggable interface modules; wherein a specific pluggable interface module is plugged into an access node port of a line termination node; wherein the line termination node is configured to transmit a request message to a control node, wherein the request message comprises interface module information related to the pluggable interface module, and wherein an activation clearance is requested, via the request message, from the control node; wherein the line termination node is configured to receive, from the control node an acknowledgement message related to the activation clearance requested by the request message, wherein the acknowledgement message corresponds to a verification operation and/or an activation clearance operation having been successful; and wherein the line termination node and/or the access node port is configured to activate the pluggable interface module.

9 . (canceled)

10 . The telecommunications network according to claim 8 , wherein the central office point of delivery and/or the broadband access network comprises a database entity;
wherein the control node has access to the database entity; wherein the control node is configured to transmit a verification request message to the database entity, wherein the verification request message comprises at least part of the interface module information related to the specific pluggable interface module; wherein the database entity is configured to perform the verification operation and/or the activation clearance operation; wherein the database entity is configured to transmit a verification acknowledgement message to the control node, wherein the verification acknowledgement message comprises, in case that the verification operation and/or the activation clearance operation having been successful, acknowledgement information related to the pluggable interface module being permitted to be activated at the access node; and
