Removing an IPSG M2PA Signaling Link

This procedure is used to remove an IPSG M2PA signaling link from the database using the dlt-slk
command. The dlt-slk command uses these parameters.
:loc – The card location of the IPSG card that the IPSG M2PA signaling link is assigned to.
:link – The signaling link on the card specified in the loc parameter.
:force – This parameter must be used to remove the last link in a linkset without having to remove
all of the routes that referenced the linkset.
The tfatcabmlq parameter (TFA/TCA Broadcast Minimum Link Quantity), assigned to linksets,
shows the minimum number of links in the given linkset (or in the combined link set in which it
resides) that must be available for traffic. When the number of signaling links in the specified linkset
is equal to or greater than the value of the tfatcabmlq parameter, the status of the routes that use
the specified linkset is set to allowed and can carry traffic. Otherwise, these routes are restricted. The
value of the tfatcabmlq parameter cannot exceed the total number of signaling links contained in
the linkset.
If the linkset type of the linkset that contains the signaling link that is being removed is either A, B,
D, E, or PRX, the signaling link can be removed regardless of the tfatcabmlq parameter value of
the linkset and regardless of the LSRESTRICT option value. When a signaling link in one of these
types of linksets is removed, the tfatcabmlq parameter value of the linkset is decreased automatically.
If the linkset type of the linkset that contains the signaling link that is being removed is C, the signaling
link can be removed only:
If the LSRESTRICT option is off. The LSRESTRICT option value is shown in the rtrv-ss7opts
output.
If the LSRESTRICT option is on and the number of signaling links assigned to the linkset will be
equal to or greater than the value of the tfatcabmlq parameter value of the linkset after the
signaling link is removed.
The tfatcabmlq parameter value of the linkset is shown in the TFATCABMLQ column of the
rtrv-ls:lsn=<linkset name> output. The tfatcabmlq parameter value can be a fixed value
(1 to 16) or 0. If the tfatcabmlq parameter value of the linkset is a fixed value, the number of
signaling links that are in the linkset after the signaling link is removed must be equal to or greater
than the tfatcabmlq parameter value of the linkset.
If the tfatcabmlq parameter value is 0, the signaling link can be removed. When the tfatcabmlq
parameter value is 0, the value displayed in the TFATCABMLQ column of the rtrv-ls output is
1/2 of the number of signaling links contained in the linkset. If the number of signaling links in
the linkset is an odd number, the tfatcabmlq parameter value is rounded up to the next whole
number. As the signaling links are removed, the tfatcabmlq parameter value of the linkset is
decreased automatically.
Canceling the RTRV-SLK Command
Because the rtrv-slk command used in this procedure can output information for a long period of
time, the rtrv-slk command can be canceled and the output to the terminal stopped. There are three
ways that the rtrv-slk command can be canceled.
