Notes

Of the 1024 maximum linksets supported, up to 255 of the linksets can be gateway linksets.

The system supports a maximum of 2800 links and all of them can be used at one time.

The links that directly connect the system with an adjacent node are grouped into one or more linksets. A linkset can contain up to 8 (international standards) or 16 (national standards) signaling links, depending on how the system was configured when the network was created.

Each linkset must be assigned the same physical links at both ends of the link (local and adjacent signaling points) and each link must be assigned the same link number.

Signaling link acknowledgments (SLTA) are the same type of maintenance message as the SLTMs received on the link.

If the gwsa=off and gwsm=off parameters are specified, all MSUs are passed.

If the gwsa=off and gwsm=off parameters are specified for all linksets, gateway screening and the GWS redirect function for the DTA feature are disabled.

If the gwsa=off and gwsm=on parameters are specified, all MSUs pass, but MRNs are generated if an MSU matches a screening condition.

If the gwsa=on and gwsm=off parameters are specified, MSUs are screened but messages are not generated.

If the gwsa=on and gwsm=on parameters are specified, MSUs are screened and MRNs are generated at the rate of one MRN every 20 seconds per link.

If the asl8=yes parameter is specified with the lst=a parameter (a linkset containing access signaling links), this indicates that the originator of the MSUs is generating 8-bit SLSs. For other linkset types, the asl8=yes parameter indicates that the adjacent STP is converting 5-bit SLSs to 8-bit SLSs. The SLS in MSUs received by the system on a linkset that has the asl8=yes parameter assigned to it will not be converted. These MSUs are assumed to contain 8-bit SLSs.

The Network Indicator Spare (nis) parameter can be specified only for ANSI and ITU-N links.

The mtprse parameter value can be specified independently of the value specified on the mtprsi parameter of the chg-stpopts command.

The MTP restart option (mtprse) is not a valid option on point-to-multipoint IP links (DCM cards equipped as SS7IPGW links).

When two linksets are used as a combined linkset, each linkset must have the same slsci and asl8 values and the same slsocbit and islsrsb/slsrsb values.

Caution:

This is not enforced in the system and there is no warning mechanism if the values of these parameters are not the same for each linkset.

MTP restart provides an orderly process for bringing signaling links back into service after the system has been isolated and restarted. A greater preference is given to restoring the STP to network service in an orderly fashion than to the speed of recovery. The time required is system dependent as shown:

  • up to 64 LIMs—62 seconds (Link Alignment Delay)
  • 64 - 127 LIMs—97 seconds
  • 128 - 191 LIMs—132 seconds
  • more than 191 LIMs—167 seconds

The slsrsb parameter alone does not provide an even distribution of ITU-ISUP messages across all links within a linkset. The system uses all four bits of the SLS to determine the actual link to route messages. Because the static bit is simply rotated within the SLS, all possible values of the SLS field are still not realized. The slsocbit parameter must also be specified to provide an even distribution across all links within the linkset. If both parameters are specified for a given linkset, the SLS field is processed in the following order.

  • The SLS is modified using the Other CIC Bit option.
  • The modified SLS is modified again using the Rotated SLS Bit option.
  • The modified SLS is used by the existing linkset and link selection algorithms to select a link
  • The ISUP message is sent out the link containing the original, unmodified SLS field.

If the ITU National Duplicate Point Code (ITUDUPPC) feature is turned on, for each group that is defined, a separate ITU national C linkset must be provisioned. The C linkset is used as the alternate route for point codes in the group.

In this command, only ITU-international and ITU national point codes support the spare point code subtype prefix (s-) and the private and spare point code subtype prefix (ps-). All point code types support the private (internal) point code subtype prefix (p-).

The ITU National and ITU National China Adjacent Point Code types indicate the format that is used for changeover and changeover acknowledgement messages. China specifies a 16-bit field for data in changeover messages. The FSN occupies the first 12 bits. The trailing 4 bits are spare and are coded as 0. ITU uses a 24-bit field for data in the extended changeover/changeover acknowledgement messages. The FSN is encoded in the first 12 bits. The last 12 bits of the field are spare and are coded as zero.

The randsls parameter value applies to SCCP ITU-T messages and Class0 and ISUP ANSI messages when random SLS generation is set to occur on a per linkset basis (the randsls=perls parameter is specified in the chg-stpopts command).

If the randsls=perls parameter is specified in the chg-stpopts command, it is recommended that the linksets in a combined linkset be provisioned with the same randsls value to avoid undesired SLS distribution.

The value specified for the ppc parameter must be a full point code. Cluster point codes and private point codes are not supported.

Invalid point codes (ANSI network = 0) can be used for the adjacent point code of an IPGWx linkset. Private point codes (p-) can be used for IPGWx linksets, as adjacent point codes (ent-ls:apc=xxx) or internal point codes (ent-rmt-appl:ipc=xxx). Ordinary point codes can be used in all cases as APCs or IPCs.

If the ISLSBR feature is turned on, and Incoming SLS Bit Rotation is applied to an MSU, then the outgoing SLS bit rotation is not applied for that MSU. If the ISLSBR feature is turned off, or Incoming SLS Bit Rotation is not applied to an MSU, then the outgoing SLS bit rotation is applied for that MSU.

The valid ISLSRSB values for ITU link sets are 1 – 4 and for ANSI link sets are 1 – 8.

The randsls parameter is applied on an incoming linkset for ANSI messages and on an outgoing linkset for ITU messages.

The chgmtp3opc parameter is applied on the outgoing linkset.

The chgmtp3opc parameter will be nullified if the sccpopts:mtprgtt option is set to fullgtt.
