4.522 rtrv-l3t

Use this command to show values of the SS7 level 3 timers. The timers are grouped into sets that are assigned to linksets.

Parameters

l3tset (optional)
Level 3 timer set table. Only one level 3 timer set table can be defined. The timer set can then be assigned to a linkset using the ent-ls or chg-l3t command.
Range:
1
Default:
Display table

Example

rtrv-l3t:l3tset=1

Dependencies

Only one timer set is supported in this release.

Notes

The timer output for this command is in seconds, even though it could have been entered in milliseconds in the chg-l3t command.

Output

rtrv-l3t:l3tset=1

Legend

  • L3TSET—Level 3 timer set table.
  • T1—Delay, in seconds, to avoid message missequencing on changeover. Also used as the ITU MTP restart isolation timer.
  • T2—Amount of time, in seconds, to wait for changeover acknowledgment
  • T3—Time controlled diversion – the delay, in seconds, to avoid missequencing on changeback
  • T4—Amount of time, in seconds, to wait for changeback acknowledgment, first attempt
  • T5—Amount of time, in seconds, to wait for changeback acknowledgment, second attempt
  • T6—Delay, in seconds, to avoid message missequencing on controlled rerouting
  • T7—Amount of time, in seconds, to wait for signaling data link connection acknowledgment
  • T8—Transfer-prohibited inhibited timer (transient solution)
  • T10—Amount of time, in seconds, to wait before repeating the signaling-route-set-test message
  • T11—Transfer-restricted timer
  • T12—Amount of time, in seconds, to wait for uninhibit acknowledgment
  • T13—Amount of time, in seconds, to wait for force uninhibit
  • T14—The amount of time, in seconds, to wait for inhibition acknowledgment
  • T15—Amount of time, in seconds, to wait before repeating the signaling-route-set-congestion test
  • T16—Amount of time, in seconds, to wait for route-set-congestion status update
  • T17—Delay, in seconds, to avoid oscillation of initial alignment failure and link restart
  • T18—Repeat TFR once by response method timers
  • IT18—Timer within an STP whose MTP restarts to supervise the receipt of routing information and the activation of the link and link set. The amount of time, in seconds, to wait for links to align and to receive TRAs from all adjacent nodes.
  • T19—Failed link craft referral timer
  • IT19—Amount of time, in seconds, for the supervision timer to wait during MTP restart to avoid ping-pong of TFP, TFR1, and TRA messages
  • T20/IT22—Amount of time, in seconds, to wait before repeating the local inhibit test
  • IT20—Amount of time, in seconds, to wait overall for the MTP restart at the signaling point whose MTP restarts
  • T21/IT23—Amount of time, in seconds, to wait before repeating the remote inhibit test
  • IT21—Overall MTP restart timer at a signaling point adjacent to one whose MTP restarts
  • T22—Timer at the restarting STP. The amount of time, in seconds, to wait for signaling links to become available
  • T23—Timer at the restarting STP. Starting after T22, the amount of time, in seconds, to wait to receive all TRA messages.
  • T24—Timer at the restarting STP with transfer function. Starting after T23, the amount of time, in seconds, to wait to broadcast all TRA messages.
  • T25—Timer at the adjacent and restarting STPs. The amount of time, in seconds, to wait for a TRA message (may be started at level 2).
  • T26—Timer at the restarting STP. The amount of time, in seconds, to wait to repeat a TRW message.

  • T30—Timer used to limit the sending of TFPs/TFRs in response to an unexpected TRA or TRW message
  • T31—False link congestion detection timer
  • T32—Link oscillation timer–Procedure A
