# AAL2 Node Configuration Mode Commands

The AAL2 Node Configuration Mode is used to configure the ATM Adaptation Layer 2 nodes to manage the Access Link Control Application Part (ALCAP) on HNB-GW for IuCS-over-ATM support towards CS core network.

IMPORTANT:

The AAL2 Node configured here will be used to bind with ATM port in PVC configuration sub-mode of ATM configuration mode for IuCS-over-ATM functionality.

IMPORTANT:

The commands or keywords/variables that are available are dependent on platform type, product version, and installed license(s).
aal2-path-id

This command set the AAL2 path identifier with AAL2 node and also used to block a particular AAL2 path.
Platform:

ASR 5000
Product:

HNB-GW
Privilege:

Security Administrator, Administrator
Syntax

    [no] aal2-path-id aal2_path_id [block]

no

Removes the configured AAL2 path identifier from this AAL2 node configuration.
aal2_path_id

Specifies the AAL2 path identifier configured with adjacent AAL2 node(s). The AAL2 path id must be unique within an AAL2 node configuration. This value is used to identify a particular path towards an adjacent AAL2 node and is sent in ALCAP protocol messages to peer where path identification is required.

The aal2_path_id must be an integer between 1 through 4294967295.

IMPORTANT:

This AAL2 path id aal2_path_id will be used to bind with ATM port in PVC configuration mode of ATM configuration mode.
block

This keyword block the AAL2 path configured with specific path identifier. When this keyword is executed ALCAP-BLO-REQUEST shall be sent to the adjacent AAL2 node.

To unblock an AAL2 path, the no keyword will be used for a locally blocked path by sending ALCAP-UNBLOCK-REQUEST to the adjacent AAL2 node.
Usage:

Use this command to configure an AAL2 path between a pair of adjacent nodes, which is identified by a unique number called AAL2 path identifier. An AAL2 path provides 248 AAL2 channels wherein each AAL2 channel is used for one circuit switched call. The AAL2 channel range defined is 8 to 255.

This command can be used for blocking or unblocking an AAL2 path towards an adjacent AAL2 node.

IMPORTANT:

The AAL2 path id configured here will be used to bind with ATM port in PVC configuration sub-mode of ATM configuration mode for IuCS-over-ATM functionality.
Example:
Following command sets the AAL2 path identifier 2 in an AAL2 node configuration.

    al2-path-id 2

Following command unblocks the AAL2 path identifier 6 which was earlier blocked in an AAL2 node configuration.

    no al2-path-id 6 block

end

Exits the current mode and returns to the Exec Mode.
Product:

All
Privilege:

Security Administrator, Administrator

Syntax

    end

Usage:

Change the mode back to the Exec mode.
exit

Exits the current mode and returns to the previous mode.
Product:

All
Privilege:

Security Administrator, Administrator

Syntax

    exit

Usage:

Return to the previous mode.
point-code

This command configure the point code of adjacent AAL2 node in SS7 format address. This point code shall be filled in the destination point-code (dpc) field of MTP3 routing label. This is required if signaling transport network is based on MTP3-broadband (MTP3B).
Platform:

ASR 5000
Product:

HNB-GW
Privilege:

Security Administrator, Administrator
Syntax

    [no] point-code point_code

no

Removes the configured point code from this AAL2 node configuration.
point_code

Defines the point code to assign to adjacent AAL2 node in SS7 format.
point_code: value entered must adhere to the point code variant selected when the AAL2 node was defined:

- ITU Range 0.0.1 to 7.255.7
- ANSI Range 0.0.1 to 255.255.255
- TTC Range 0.0.1 to 15.31.255
- a string of 1 to 11 combined digits ad period.

Usage:

Use this command to configure configure the point code of adjacent AAL2 node in SS7 format address. This point code shall be filled in the destination point-code (dpc) field of MTP3 routing label. This is required if signaling transport network is based on MTP3-broadband (MTP3B).

A maximum of 16 point codes for adjacent AAL2 nodes can be configured in one ALCAP service.
Example:
The following command configures the point code 4.121.5 for adjacent AAL2 node.

    point-code 4.121.5

The following command removes the point code 4.121.15 from AAL2 node configuration.

    no point-code 4.121.15
