chg-feat
- mtprs=on
(to turn on MTP Restart for ANSI signaling links) and itumtprs=on
(to turn on MTP Restart for ITU signaling links)chg-stpopts
on=mtprsi
- to enable the MTP Restart process, or off=mtprsi
, to disable the MTP Restart process. When the on=mtprsi
parameter is specified for the chg-stpopts
command, the value yes
is shown in the MTPRSI
field of the rtrv-stpopts
output. When the off=mtprsi
parameter is specified for the chg-stpopts
command, the value no
is shown in the MTPRSI
field of the rtrv-stpopts
output. The system default value for this option is no
.mtprsit
- the MTP restart isolation timer - 2000 to 900000 milliseconds. The system default value is 5000 milliseconds.The MTP restart feature is applied to the signaling links in a linkset by specifying the mtprse=yes
parameter of the ent-ls
or chg-ls
commands. Perform Adding an SS7 Linkset or Changing an SS7 Linkset to specify the mtprse
value for a linkset.
If the MTP restart feature is turned on, the alignment of all signaling links is delayed until all the LIMs containing signaling links are in service. This allows the EAGLE to be restored to network service in an orderly fashion and allows all the LIMs containing signaling links to participate in the MTP restart process. The amount of time that the alignment of the signaling links is delayed is dependent on the number of LIMs and DCMs in the EAGLE and is shown in Table 3-8. Table 3-8 shows and example of MTP signaling link alignment delay for LIMs.
Note:
The MTP restart feature can be used on linksets containing non-IP signaling links, IP signaling links with theipliml2=m2pa
parameter, or IPSG signaling links with the ipsg=yes
and adapter=m2pa
parameters.Table 3-8 MTP Restart Signaling Link Alignment Delay

If the ANSI MTP restart feature is on (MTPRS = on
in the rtrv-feat
command output), the mtprsi
parameter is set to yes
, and at least one ANSI linkset has the mtprse
parameter set to yes
, the EAGLE starts these level 3 timers; T22, T23, T24, T25, T26, T28, T29, and T30 to control the behavior of the MTP restart feature. These timers control when the TRA and TRW network management messages are sent to the nodes adjacent to the EAGLE when the EAGLE is going through the MTP restart process. When these timers are first introduced to the EAGLE, the system default values for these timers are:
To change the values of these timers, perform Changing Level 3 Timers.
If the ITU MTP restart feature is on (ITUMTPRS = on
in the rtrv-feat
command output), the mtprsi
parameter is set to yes
, and at least one ITU linkset has the mtprse
parameter set to yes
, the EAGLE starts these level 3 timers; IT18, IT19, IT20, and IT21 to control the behavior of the ITU MTP restart feature. These timers control when the TRA and TRW network management messages are sent to the nodes adjacent to the EAGLE when the EAGLE is going through the MTP restart process. When these timers are first introduced to the EAGLE, the default values for these timers are:
To change the values of these timers, perform Changing Level 3 Timers.
If both the ANSI and ITU MTP restart features are on, the mtprsi
parameter is set to yes
, and at least one ANSI and ITU linkset has the mtprse
parameter set to yes
, the EAGLE starts the level 3 timers for both the ANSI and ITU MTP restart features to control the behavior of both the ANSI and ITU MTP restart features.
