This threshold is reached when the signaling link's actual usage exceeds the percentage of the signaling
link's fair share of the linkset's IPTPS or the percentage of the IPGWx card's capacity.
A signaling link's fair share of linkset's IPTPS is the linkset's IPTPS divided by the number of in-service
links in the linkset. For example, if the linkset IPTPS is 4000 and there are 4 signaling links in the
linkset, all in-service, then the signaling link's fair-share would be 1000 IPTPS (4000/4=1000).

When this threshold is exceeded, a minor alarm (UAM 0116) is generated. When the amount of traffic
on the signaling link falls below this threshold, UAM 0116 is automatically cleared and UAM 0119 is
generated.
The signaling link IPTPS alarm shows that the linkset IPTPS is set too low for the linkset or that the
IPGWx card's capacity has been exceeded. Setting the signaling link IPTPS alarm threshold lower than
the linkset IPTPS alarm threshold can give the user an earlier indication that the linkset IPTPS is
inadequate or that traffic is not balanced across the links in the linkset.
:multgc – specifies whether multiple group codes (for 14-bit ITU-N point codes) are supported for
the linkset. When this parameter value is yes, secondary adjacent point codes whose group codes are
different from the adjacent point code of the linkset can be assigned to the linkset. If the parameter
value is no, the group code of the secondary adjacent point code must be the same as the group code
of the linkset's adjacent point code. For more information on secondary adjacent point codes, go to
the "Configuring an ITU Linkset with a Secondary Adjacent Point Code (SAPC)" procedure in the
Database Administration Manual - SS7 .
This parameter only applies to linksets whose adjacent point codes are either ITU international point
codes or ITU national point codes. All the signaling links in this linkset must be assigned to cards
running the IPGWI application. For more information on assigning signaling links to cards running
the IPGWI application, go to the
The ITU duplicate point code feature must be on before this parameter can be specified. Verify this
with the rtrv-feat command. If the ITU duplicate point code feature is turned on, the ituduppc
field should be set to on. If the ITU duplicate point code feature is not turned on, enter the
chg-feat:ituduppc=on command.
Note: Once the ITU duplicate point code feature is turned on with the chg-feat command, it cannot
be turned off.
