Adding an SS7 Signaling Link

This procedure is used to add an ANSI SS7 low-speed signaling link to an MPL card using the ent-slk command with these parameters shown in Table 3-14.

Table 3-14 Signaling Link Parameters

loc	link	lsn
slc	l2tset	bps
ecm	pcrn1	pcrn2

The ent-slk command contains other optional parameters that are not used this procedure. These parameters are discussed in more detail in the Commands Manual or in these sections. These sections are also used to configure ITU signaling links.

These procedures in this manual.
- The Adding an E1 Signaling Link procedure
- The Adding a T1 Signaling Link procedure
- The Adding an ATM High-Speed Signaling Link procedure.
These procedures in Database Administration - IP7 User's Guide
- Adding an IPGWx Signaling Link
- Adding an IPLIMx Signaling Link
- Adding an IPSG M3UA Signaling Link
- Adding an IPSG M2PA Signaling Link

:loc – The card location of the LIM that the SS7 signaling link will be assigned to.

:link – The signaling link on the card specified in the loc parameter.

:lsn – The name of the linkset that will contain the signaling link.

:slc – The signaling link code. The SLC must be unique within the linkset. It must be the same at both the EAGLE location and the distant node.

:l2tset – The level 2 timer set table. A signaling link may be assigned to any of the thirty tables. The type of linkset the signaling link is assigned to and the LIM’s application determines the value of the l2tset parameter. The level 2 timer set tables are defined in Changing Level 2 Timers .

:bps – The transmission rate for the link in bits per second.

:ecm – Error correction method

:pcrn1 – The threshold of the number of MSUs available for retransmission. If the error correction method being used is PCR (:ecm=pcr), and this threshold is reached, no new MSUs or FISUs are sent. The retransmission cycle is continued up to the last MSU entered into the retransmission buffer in the order in which they were originally transmitted.

:pcrn2 – The threshold of the number of MSU octets available for retransmission. If the error correction method being used is PCR (:ecm=pcr), and this threshold is reached, no new MSUs or FISUs are sent. The retransmission cycle is continued up to the last MSU entered into the retransmission buffer in the order in which they were originally transmitted.

These items must be configured in the database before an SS7 signaling link can be added:

Shelf – see "Adding a Shelf in Database Administration - System Management User's Guide
Card – see "Adding an SS7 LIM" in Database Administration - System Management User's Guide
Destination Point Code – see Adding a Destination Point Code
Linkset – Adding an SS7 Linkset .

Verify that the link has been physically installed (all cable connections have been made).

To configure the EAGLE to perform circular routing detection test on the signaling links, perform the Configuring Circular Route Detection procedure.

Note:

Circular route detection is not supported in ITU networks.

To provision a EAGLE with more than 1200 signaling links, the EAGLE must have certain levels of hardware installed. See the Requirements for EAGLEs Containing more than 1200 Signaling Links section for more information on these hardware requirements.

The EAGLE can contain a mixture of low-speed, E1, T1, ATM high-speed, and IP signaling links. The Determining the Number of High-Speed and Low-Speed Signaling Links section describes how to determine the quantities of the different types of signaling links the EAGLE can have.

SS7Signaling Link Parameter Combinations

Table 3-15 shows the parameters and values that can be used to provision an ANSI SS7 signaling link.

Table 3-15 SS7 Signaling Link Parameter Combinations

MPL Signaling Link (See Note 1)
Mandatory Parameters
:loc = location of the MPL with the SS7ANSI application and the LIMDS0 card type.
:link = A, A1, A2, A3, B, B1, B2, or B3 (See Note 4)
:lsn = linkset name (See Note 3)
:slc = 0 - 15
Optional Parameters
:bps = 56000 default value = 56000
:l2tset = Table 3-16
:ecm = basic or pcr default value = basic
:pcrn1 = 1 - 127 (See Note 2) default value = 76
:pcrn2 = 300 - 35500 (See Note 2) default value = 3800
Notes: This procedure is not used to configure ATM, IP, E1, or T1 signaling links. To configure these types of links, perform one of these procedures: E1 signaling links – Adding an E1 Signaling Link. T1 signaling links – Adding a T1 Signaling Link. ATM signaling links – Adding an ATM High-Speed Signaling Link. IP signaling links – “Adding an IPLIMx Signaling Link,” "Adding an IPGWX Signaling Link, " "Adding an IPSG M3UA Signaling Link," or " Adding an IPSG M2PA Signaling Link" procedures in Database Administration - IP7 User's Guide. These parameters can be specified only with the `ecm=pcr` parameter. The linkset adjacent point code type must be ANSI. The domain of the linkset adjacent point code must be SS7. The `port` parameter can be used in place of the `link` parameter to specify the signaling link on the card.

Canceling the REPT-STAT-SLK and RTRV-SLK Commands

Because the rept-stat-slk and rtrv-slk commands used in this procedure can output information for a long period of time, the rept-stat-slk and rtrv-slk commands can be canceled and the output to the terminal stopped. There are three ways that the rept-stat-slk and rtrv-slk commands can be canceled.

Press the F9 function key on the keyboard at the terminal where the rept-stat-slk or rtrv-slk commands were entered.
Enter the canc-cmd without the trm parameter at the terminal where the rept-stat-slk or rtrv-slk commands were entered.
Enter the canc-cmd:trm=<xx>, where <xx> is the terminal where the rept-stat-slk or rtrv-slk commands were entered, from another terminal other that the terminal where the rept-stat-slk or rtrv-slk commands was entered. To enter the canc-cmd:trm=<xx> command, the terminal must allow Security Administration commands to be entered from it and the user must be allowed to enter Security Administration commands. The terminal’s permissions can be verified with the rtrv-secu-trm command. The user’s permissions can be verified with the rtrv-user or rtrv-secu-user commands.

For more information about the canc-cmd command, go to Commands User's Guide.

Display the maximum number of signaling links the EAGLE can have and the number of signaling links that are currently provisioned by entering the rtrv-tbl-capacity command.
This is an example of the possible output.

```
Note:
The rtrv-tbl-capacity command output contains other fields that are not used by this procedure. If you wish to see all the fields displayed by the rtrv-tbl-capacity command, refer to the rtrv-tbl-capacity command description in Commands User's Guide.

If the addition of the new signaling link will exceed the maximum number of signaling links the EAGLE can have (in this example, the maximum number of signaling links is 1200), and the maximum number of signaling links is 2800, this procedure cannot be performed. The EAGLE cannot contain more than 2800 signaling links.

If the addition of the new signaling link will exceed the maximum number of signaling links the EAGLE can have, and the maximum number of signaling links is less than 2800, perform the Enabling the Large System # Links Controlled Feature procedure to enable the desired quantity of signaling links. After the new quantity of signaling links has been enabled, continue the procedure with 2.

If the addition of the new signaling link will not exceed the maximum number of signaling links the EAGLE can have, continue the procedure with 2.

Display the current signaling link configuration using the rtrv-slk command. This is an example of the possible output.

If the desired linkset is not in the database, perform Adding an SS7 Linkset to add the linkset to the database. After the linkset has been added to the database, continue the procedure with 6.

If the desired linkset is in the database, continue the procedure with 5.

If the IPSG and IPGWAPC values for the linkset are no, continue the procedure with 6.

Add the signaling link to the database using the ent-slk command. Use Table 3-15 as a guide for the parameters that can be specified with the ent-slk command. For this example, enter these commands.
