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.

: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:

  1. 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:

  2. These parameters can be specified only with the ecm=pcr parameter.
  3. The linkset adjacent point code type must be ANSI. The domain of the linkset adjacent point code must be SS7.
  4. 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.

  1. 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.

    rlghncxa03w 09-07-19 21:16:37 GMT EAGLE5 41.1.0
    
    SLK      table is (        7 of      1200)   1% full
    

    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.

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

    The signaling link cannot be assigned to a linkset whose IPSG or IPGWAPC values are yes. If either the IPSG or IPGWAPC value for the linkset is yes, repeat the procedure from 4 and choose another linkset.

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

  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.

    ent-slk:loc=1201:link=a:lsn=ls01:slc=0:l2tset=1

    ent-slk:loc=1202:link=b:lsn=ls02:slc=0:l2tset=2

    ent-slk:loc=1311:link=a:lsn=ls01:slc=2:l2tset=1

    ent-slk:loc=1311:link=a1:lsn=ls05:slc=2:l2tset=5

    ent-slk:loc=1311:link=b:lsn=ls03:slc=2:l2tset=3

    ent-slk:loc=1311:link=b1:lsn=ls07:slc=1:l2tset=7

    When each of these commands have successfully completed, this message should appear.

    ENT-SLK: MASP A - COMPLTD
    

    Note:

    If adding the new signaling link will result in more than 700 signaling links in the database and the OAMHCMEAS value in the rtrv-measopts output is on, the scheduled UI measurement reports will be disabled.
  7. Verify the changes using the rtrv-slk command and specifying the card location specified in 6. For this example, enter these commands.

    rtrv-slk:loc=1201

    This is an example of the possible output.

    If any of the cards shown in this step contain the first signaling link on a card, continue the procedure with 8.

    If signaling links were assigned to all the cards shown in this step when 6 was performed, continue the procedure with 9.

  8. Bring the cards into service with the rst-card command, specifying the location of the card specified in 7. For this example, enter these commands.

    rst-card:loc=1202

    rst-card:loc=1311

    When each of these commands have successfully completed, this message should appear.

    rlghncxa03w 06-10-23 13:05:05 GMT EAGLE5 36.0.0
    Card has been allowed.
    
  9. Activate all signaling links on the cards using the act-slk command, specifying the card location and signaling link specified in 6 . For this example, enter these commands.

    act-slk:loc=1201:link=a

    act-slk:loc=1202:link=b

    act-slk:loc=1311:link=a

    act-slk:loc=1311:link=a1

    act-slk:loc=1311:link=b

    act-slk:loc=1311:link=b1

    When each of these commands have successfully completed, this message should appear.

    rlghncxa03w 06-10-07 08:31:24 GMT  EAGLE5 36.0.0
    Activate Link message sent to card
    
  10. Check the status of the signaling links added in 6 using the rept-stat-slk command with the card location and signaling link. The state of each signaling link should be in service normal (IS-NR) after the link has completed alignment (shown in the PST field). For this example, enter these commands.

    rept-stat-slk:loc=1201:link=a

    This is an example of the possible output.
