# SS7 Routing Domain Configuration Mode Commands

The SS7 Routing Domain configuration mode is used to configure Signaling System 7 (SS7) parameters. For convenience in configuration management, all SS7 parameters have been collected into a proprietary grouping called an SS7 routing domains.

inbound-asp-identifier validate

This command enables validation of ASP identifiers inbound to the SGSN via routes defined with this SS7 routing domain.

IMPORTANT:

This command is only available in Release 8.1 and higher releases.
Platform:

ASR 5000
Product:

SGSN
Privilege:

Security Administrator, Administrator
Syntax

    inbound-asp-identifier
    validate default inbound-asp-identifier
    validate no inbound-asp-identifier
    validate

default

Validates the inbound ASP Id.
no

Disables validation of the inbound ASP Id.
Usage:

The standard is to validate the ASP Id. However, in some circumstances it is necessary to skip such validation. For example, if the same ASP Id is assigned to more than one RNC (peer-server).
Example:
Use the following command to skip validation of inbound ASP Ids:

    no inbound-asp-identifier
    validate

Use either of the following commands to enable validation if it has been disabled:

    default inbound-asp-identifier validate

    inbound-asp-identifier validate

linkset

This command creates an instance of an MTP3 linkset and enters the Linkset configuration mode. See the Linkset configuration mode chapter for the commands to configure the linkset.

HNB-GW
Privilege:

Syntax

    linkset id idno linkset id id

no

Removes the identified linkset definition from the system configuration.
id

This value uniquely identifies a linkset for the specific SS7 routing domain.

id : Must be an integer of 1 to 49.
Usage:

This command creates instances of linkset configurations and provides access to the linkset configuration mode.
Example:
Use the following command to create the 12th linkset:

    linkset id 12

MTU-size

This command has been deprecated.
peer-server

This command creates a peer-server instance to setup a SIGTRAN peer for sending and receiving M3UA traffic. Completing the command automatically enters the peer- server configuration mode. To define 1 or more (up to 145) peer servers, use the commands documented in the Peer-Server Configuration Mode chapter in this reference.

Syntax

    peer-server id srvr_id

    no peer-server id srvr_id

no

Removes the identified peer-server definition from the system configuration.
srvr_id

srvr_id uniquely identifies a peer-server. The id must be an integer from 1 to 144.
Usage:

Use the following command to create a definition for peer-server 2 and enter the configuration mode to configure the communication parameters for peer-server 12.
Example:

    peer-server id 12

route

This command configures SS7 routes for the current SS7 routing domain.

    id id | peer-server-id srvr_id }

no

Removes the SS7 route from the current SS7 routing domain configuration.
destination-point-code dp_code

Specifies the SS7 destination point code for this route.

Reminder: the point-code structure must match the variant defined for the SS7 routing domain when the SS7RD was configured in the global configuration mode.

ssf

This command sets the network indicator in the subservice field for SS7 message signal units (MSUs).
Platform:

ASR 5000
Product:

SGSN

HNB-GW
Privilege:

Security Administrator, Administrator
Syntax

    ssf ( international | national | reserved | spare }

international

The network indicator identifies the message as international with a point code structure that does not match the national point code structure,
national

The network indicator identifies the messages as having a national point code structure.
reserved

Provides an alternate network indicator for national messages.
spare

Provides an alternate network indicator for international messages.
Usage:

In SS7 signaling, the Message Transfer Part (MTP) Level 2 message signal units (MSUs) contain a service information octet (SIO). The SIO field in an MSU contains a 4-bit subservice field (SSF) followed by a 4-bit service indicator. The indicator carried in the message’s routing information typically identifies the structure of the point code as a message from within a nation or as a message coming from outside the nation - international. As well, the 4-bit SSF determines the point code structure of the messages transmitted from the SGSN.
Example:
For messages being transmitted within a country, set the indicator to national with the following command.

    ssf national
