Adding an IPSG M3UA Linkset
This procedure is used to configure IPSG M3UA linksets in the EAGLE using the ent-ls
command with these parameters.
:lsn
– The name of the linkset. The linkset name can contain up to 10 characters, with the first character being a letter. However, the SEAS interface supports only eight characters. If this linkset is displayed on the SEAS interface and the linkset name contains more than eight characters, only the first eight characters in the linkset name are shown. If this linkset name contains more than eight characters, and is specified with the linkset commands on the SEAS interface, only the first eight characters can be specified.
:apc/apca/apci/apcn/apcn24
– Adjacent point code – the point code identifying the node that is next to the EAGLE. The adjacent point code can be one of the following types of point codes:
:apc
/apca
– ANSI point code, ANSI private point code
:apci
– ITU-I point code, ITU-I spare point code, ITU-I private point code, ITU-I private spare point code.
:apcn
– 14-bit ITU-N point code, 14-bit ITU-N spare point code, 14-bit ITU-N private point code, 14-bit ITU-N private spare point code.
:apcn24
– 24-bit ITU-N point code, 24-bit ITU-N private point code.
Note:
See the “Point Code Formats” section in Database Administration - SS7 User's Guide for a definition of the point code types that are used on the EAGLE and for a definition of the different formats that can be used for ITU national point codes.:lst
– The linkset type of the linkset. For an IPSG M3UA linkset, only one value can be specified, A.
:ipsg
– This parameter specifies whether or not the linkset is an IPSG linkset. This parameter has two values, yes
(if the linkset is an IPSG linkset) or no
(if the linkset is not an IPSG linkset). For this procedure, the ipsg
parameter value must be yes
.
:maxslktps
– The maximum number of transactions per second (TPS) for all signaling links that are assigned to the IPSG M3UA linkset. See Maximum Card Capacity for Different Card Types for MaxTPS values.
:rsvdslktps
– The number of transactions per second (TPS) that is assigned to each IPSG signaling link that will be in the linkset. See Maximum Card Capacity for Different Card Types for MaxTPS values. The slktps
parameter can be used in place of the rsvdslktps
parameter.
:tpsalmtype
– The TPS threshold that will generate alarms. This parameter has two values.
rsvdslktps
- TheRSVDSLKTPS
threshold generates alarms.maxslktps
- TheMAXSLKTPS
threshold generates alarms.
:lsusealm
– The linkset’s TPS alarm threshold, from 10 to 100 percent of the linkset’s TPS. When this threshold is reached, a major alarm (UAM 0115) is generated. When the linkset’s TPS falls below this threshold, UAM 0115 is automatically cleared and UAM 0118 is generated.
:slkusealm
– The signaling link TPS alarm threshold, from 10 to 100 percent of the signaling link’s fair share of the linkset’s TPS from 10 to 100 percent of the IPSG card’s capacity (5000 TPS). 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 TPS or the percentage of the IPSG card’s capacity.
A signaling link's fair share of linkset’s TPS is the linkset’s TPS divided by the number of in-service links in the linkset. For example, if the linkset TPS is 4000 and there are 4 signaling links in the linkset, all in-service, then the signaling link's fair-share would be 1000 TPS (4000/4=1000). Table 6-2 shows this calculation for a linkset with 1, 2, 3 and 4 in-service signaling links.
Table 6-2 Signaling Link Fair Share Example
Number of In-Service Signaling Links | Linkset TPS | Signaling Link Fair Share of the Linkset TPS |
---|---|---|
4 |
4000 |
1000 |
3 |
4000 |
1333 |
2 |
4000 |
2000 |
1 |
4000 |
4000 |
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 TPS alarm shows that the linkset TPS is set too low for the linkset or that the IPSG card's capacity has been exceeded. Setting the signaling link TPS alarm threshold lower than the linkset TPS alarm threshold can give the user an earlier indication that the linkset TPS is inadequate or that traffic is not balanced across the links in the linkset.
:adapter
- This parameter specifies the adapter layer for the signaling links that will be assigned to the IPSG M3UA linkset. This parameter has two values, m2pa
and m3ua
. For an IPSG M3UA linkset, the adapter
parameter value must be m3ua
.
:rcontext
- This parameter specifies the routing context value that is assigned to the IPSG M3UA linkset. The value for this parameter is from 0 to 4294967295. The default value for this parameter is none
, no value is specified.
:asnotif
- This parameter specifies whether or not AS notifications will be sent for the IPSG M3UA linkset. This parameter has two values, yes
, AS notifications will be sent for the linkset, and no
, AS notifications will not be sent for the linkset. The default value for this parameter is yes
.
The adjacent point code (APC) for the linkset must be defined in the database, must be in the SS7 domain, and cannot match the point code or capability point code of the EAGLE. The domain of the point code is shown in the DMN
field in the output of the rtrv-dstn
command. The point code of the EAGLE is shown in the PCA
, PCN
, PCN24
, or PCI
fields and the capability point code of the EAGLE are shown in the CPCA
, CPCN
, CPCN24
, or CPCI
fields in the output of the rtrv-sid
command. An ANSI adjacent point code must be a full point code and cannot be a cluster point code or a network routing point code. The adjacent point code of the linkset cannot be a proxy point code, cannot have a proxy point code assigned to it, and cannot be assigned to another linkset.
If the APC is not in the destination point code table, go to the “Adding a Destination Point Code” procedure in Database Administration - SS7 User's Guide and add the APC to the destination point code table.
Adding the IPSG M3UA linkset cannot exceed the maximum total provisioned system TPS shown in the rtrv-tps
output. An IPSG M3UA linkset uses from 100 to 5000 TPS, as provisioned by the maxslktps
parameter.
- The IP TPS values of some IPGWx linksets have to be changed.
- The MAXSLKTPS values of some IPSG linksets (and the RSVDSLKTPS values if necessary) have to be changed.
- Some ATM high-speed signaling links have to be removed.
- An IPLIMx card that contains signaling links has to be removed.

Canceling the RTRV-LS
and RTRV-DSTN
Commands
Because the rtrv-ls
and rtrv-dstn
commands used in this procedure can output information for a long period of time, the rtrv-ls
and rtrv-dstn
commands can be canceled and the output to the terminal stopped. There are three ways that the rtrv-ls
and rtrv-dstn
commands can be canceled.
- Press the
F9
function key on the keyboard at the terminal where thertrv-ls
orrtrv-dstn
commands were entered. - Enter the
canc-cmd
without thetrm
parameter at the terminal where thertrv-ls
orrtrv-dstn
commands were entered. - Enter the
canc-cmd:trm=<xx>
, where<xx>
is the terminal where thertrv-ls
orrtrv-dstn
commands were entered, from another terminal other that the terminal where thertrv-ls
orrtrv-dstn
commands were entered. To enter thecanc-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 thertrv-secu-trm
command. The user’s permissions can be verified with thertrv-user
orrtrv-secu-user
commands.
For more information about the canc-cmd
command, go to Commands User's Guide.
