Nortel Network Time Syncronization 2

[srmega41]

This is for everyone who has a group of networked PBX's, using PRI for connectivity. This will work with as many systems as you can think of, as I have found no limits anywhere. Be advised this uses a DN from each PBX, and each DN must be defined with the Coordinated Dialing Plan of your PBX network. All programming is done in LD 2, and all that is required is ISDN package 161.

. SLDN xxxxxx <-- This is the DN you will use for Time Sync

. STSS (STDA), MAST, SLAV <-- This sets which will be master and slave (You only should have one master in your network)  STDA is for Stand Alone, not sure how this would be helpful.  All non-master sites must be set to SLAV in order to communicate

. STSC (0), x <-- Customer number in charge of Time Sync

. SMDN xxxxxxx <-- If the system is a slave, this is where you input the master DN. If this is a master site, this becomes a backup if the master ever needs to be reset, like after a SYSLOAD.  [COLOR=red]Include all routing digits necessary, like AC1 and ESN if that is how your dialing plan is set up![/color]

. SMOD (BKGD), DSVC <-- This sets whether the service runs in the background or at midnight.

. SDEL (sign) (hr) (min) <-- This is where you set the difference, or Delta, between the local switch and the master location.  (sign = 0 or 1, 0 = master is behind [b]local[/b] time, 1 = master is ahead of [b]local[/b] time) (hr = number of hours difference) (min = number of minutes difference)

I would recommend running this in the background, so your times to do not fluxuate during the day, in the event of an INI or loss of a T1.

You can print out all of these setting in LD 2 by replacing the leading S with a T. You can also print the DN in ld 20, and it will shoe TYPE as TIME. Adjustments to the time on any slave system will immediatly trigger a sync with the master.

We have an 81C as our master, using an RLOGIN script to set the correct time on a nightly basis. We then have our 80 11C's set up as slaves to the 81, thereby syncing the time with all PBX's using 1 script. We even have three 11C's in a different time zone, and the adjustments in Delta set (SDEL) work just fine.

thanks amigo, that will come in handy, you might want to add a script to keep the main switch on track..
