TN2181 Tone Clock

tele234 · July 3rd, 2003, 08:48 AM

Have a G3si, critical reliablity, duplicated, However the TN2181 tone clock in A cabinet will not go inservice, when the spe changes the tone clock always stays in B cabinet. The A cabinet contains a TN2400/TN2401, the B cabinet just contains a TN2400, and if i force the interchange to change tone clocks I get alarm and the system changes the tone clock back to B. And the system is set to change spe and tone daily..?????

I assume the card is good. You tried interchanging the cards and you get the same problem where the tone clock stays on A cabinet?

tele234 · July 3rd, 2003, 09:42 AM

Correct, I have changed the cards from B to A, I get the same problem, Both cards are the same version.. I also took a new card that was working fine and still get the same.

What happens if you leave the B board out?

tele234 · July 3rd, 2003, 10:11 AM

The system goes into alarm and call process stop! But Avaya dialed in and stated that nothing is wrong with A 's board..

mtfs · July 3rd, 2003, 10:22 AM

Why is it that A has a 2400/2401 pack and B only has 2400 pack.  Does this have anything to do with it?

If you have a maintenace agreement. I would just call them up and tell them to replace it.

tele234 · July 3rd, 2003, 11:27 AM

The A cabnet is running the sandwich board because the J number on the cabinet will not run packets on the back plane, we need the TN2401 to run packet interface, Otherwise the PRI wont work.
I have asked that question to Avaya and they state should work.
We ARE THE MAINTENACE AGREEMENT

Did you ever find a resolution for this? I'm sure everyone is curious as i am.
Thanks

tele234 · July 8th, 2003, 07:03 AM

no not yet, but the system just keeps on running...

System
Clocks/IPSI
Interchange

For high-reliability configurations, there are duplicate IPSIs on IPSI-controlled
port networks. For critical-reliability configurations, there are both duplicate
Tone-Clock circuit packs on non-IPSI controlled port networks and duplicate
IPSIs on IPSI-controlled port networks. When this option is turned on a system
clock or IPSI interchange is automatically initiated on each port network
possessing duplicated Tone-Clock circuit packs or IPSIs. Each port network
interchanges in the standby system clock or IPSI for 20 seconds. During this
time the newly-active circuit pack is tested and system health is monitored.
Then an interchange is made back to the originally-active circuit pack. This field
indicates the days that interchanges occur (daily, days of the week, or no). “No”
prevents interchanges. (no)

The information above was taken from the G3 Maintanence Book. If you look up the command "ch sys main" you will see a field that indicates if the tone clocks should interchange or not. As you can see if the clocks are set to auto interchange it's a temp. swap. This is normal. Use the "stat sys 1" command to check the health of the tone clocks. The SPE and tone clocks work independly of each other.

so then IF the interchange is SET for daily, your saying that the tone clocks SHOULD change daily,Or not Change?
Well the tone clock interchange is set for daily and IT will not change, however I can flop the cards (IE move tone clock in B to A ) then the tone clock will only stay @ the B carrier.
I guess I am still confused,
The tone clock in A cabinet never goes active, if I frog(Flop) the circuit cards, only the board in B stays as the active circuit board.

What did tech support say?

shoreguy · July 21st, 2003, 11:30 AM

What should happen is this. Assume that you have two tone clocks one in A the other in B. Futher assume that B is active and Ais standbye. Withe the "sys main" set to do a clock interchange every night the A clock will be made active and tested with traffic for twenty seconds and then the B clock be become the active clock again. This is normal. If you want to truley change the clocks, first use the stat sys 1 command to ensure that tboth clocks are in service. Once you have done that use the set tone 1A command to change from the clock in 1B to the clock in 1A. The clocks will stay in this configuration until there is a failure or you follow the same process in reverse - set tone 1B

tele234 · July 22nd, 2003, 03:39 PM

Ok, now that sounds different, But question, If I change the tone clock and the system goes into alarm, wouldnt that suggest that the tone clock circuit card is bad, Or would that mean that slot is bad, cause if I force the interchange the system will alarm, But if I change the circuit cards around B to A, the card that was in A that alarmed, will not alarm when in B, But B will alarm if in cabinet A. So I guess this is more information at this point.. But It has Avaya confused, cause according to tier 3, the system IS supposed to change tone clock daily.. GO figure..
