5.1.3 Local Signaling Points

A Signaling Point is a set of signaling equipment represented by a unique point code within an SS7 domain. A Local Signaling Point (LSP) is a logical element representing an SS7 Signaling Point assigned to an MP Server Group. An LSP has an SS7 domain and a true point code. The LSP may optionally be assigned up to two Capability Point Codes (CPCs), which are point codes that can be shared with other LSPs.

Select the VSTP, and then Configuration, and then Local Signaling Points page. The page displays the elements on the Local Signaling Points View, Insert, and Edit pages.

Note:

Data Input Notes apply to the Insert and Edit pages only; the View page is read-only.

Table 5-3 Local Signaling Points Elements

Element	Description	Data Input Notes
Local Signaling Point Name	Unique name of the Local Signaling Point. This is a mandatory field. The value must be unique, and cannot be edited if it is referenced in any other configuration.	Format: Input text box; Valid characters are alphanumeric and underscore. Must contain at least one alpha and must not start with a digit. Range = A 32-character string.
SS7 Domain type	This defines the type of SS7 domain. This is a mandatory field.	Format: Drop down menu Range = Ansi, Itui, Itun, Itun24, Itun_s, Itui_s
PC Type	This defines the types of point code. This is a mandatory field.	Format: Drop down menu Range = Tpc,Spc,Cpc Note: The LSP cannot be edited when the PC Type parameter value is Tpc. Therefore, to change the true point code (PC type = TPC), you need to delete the LSP and add again.
CPC Type	This defines the types of services or applications which are added in VSTP.	Format: Drop down menu Range = Stp, Eir, Gport, Inpq, Atinp
MTP Point Code	The MTP Point Code that identifies this LSP. Only one LSP can have this MTP Point Code.The format differs according to Domain type. This is a mandatory field. Only one LSP can have this MTP Point Code if the PC type is TPC or SPC. The LSP may optionally be assigned up to two Capability Point Codes (CPCs), which are point codes that can be shared with other LSPs.	Valid characters are integers seperated with hyphen(-)
Group Code	The ITUN group code for duplicate point code feature. This is an optional field. The value can only be edited if the PC Type field value is CPC.	Format: Input Text Box Range = aa, zz Default Value: aa

You can perform add, edit, or delete tasks on VSTPConfigurationLocal Signaling Points page.

Adding a Local Signaling Point

Perform the following steps to configure a new Local Signaling Point:

1. Click Insert.

   Note:

   The new Local Signaling Point must have a name that is unique across all Local Signaling Points at the SOAM. In addition, the Local Signaling Point's IP Port combination must also be unique across all Local Signaling Points configured at the SOAM.
2. Enter the applicable values.
3. Click OK, Apply, or Cancel

Important:

After adding an LSP, it is mandatory to restart the MP for the system to get updated.

Restart of MP is mandatory for the MPs to get the update after adding a true point code (TPC) irrespective of the domain.

Editing a Local Signaling Point

Use this procedure to change the field values for a selected Local Signaling Point:

1. Select the Local Signaling Point row to be edited.
2. Click Edit
3. Enter the updated values.

   Note:

   • The Local Signaling Point Name field cannot be changed.
   • The values of MTP Point Code and Group Code can be edited only if the value of PC Type is CPC.
4. Click OK, Apply, or Cancel

Deleting a Local Signaling Point

Use the following procedure to delete a Local Signaling Point.

Note:

You cannot delete a Local Signaling Point if it is part of the configuration of one or more Linksets.

1. Select the Local Signaling Point to be deleted.
2. Click Delete.
3. Click OK or Cancel.

Important:

After deleting an LSP, it is mandatory to restart the MP for the system to get updated.

Restart of MP is mandatory for the MPs to get the update after deleting a true point code (TPC) irrespective of the domain.
