What is an OFD?

It's a file, which MATWorX can generate, which is essentially a listup of all the command data in your 2000 IPS. You can generate an OFD by going into MATWorX and selecting the Save/Load/Verify from the Menus.

When Can I Generate An OFD?

You're supposed to do it offiline (rotary switch in position 2, system reset) and via a Serial connection. If you switch it to 19200 baud, it should take less than 20 minutes, depending on how much data is on the system. MATWorX will let you generate an OFD whilst in ONLINE mode, but it's not recommended because certain parts of the programming may be in use, or be changed whilst the generation is occuring, thus providing you with corrupt data.

You can also generate an OFD over serial or modem cable - however for some reason it suggests it will often take hours, and I wouldn't trust the outcome!

Why Would I Generate An OFD?

You may simply want a routine backup of all your PBX programming. You may be making lots of changes, which will require a save to ROM and therefore not be un-do-able, and want a get-out-of-jail-free card. If you're performing an MP firmware upgrade, then you WANT to take an OFD incase it all goes pear shaped.

Things To Know Once you have taken your OFD (which will usually be a few hundred kilobytes)

You can then use it to restore to another, or the same processor. It's also generally accepted that you clear down all the data on the system (also rotary 2, reset, serial connection, CM00, 1, CCC). You apply the OFD in the same place you generated it, except under the LOAD section.

You can also verify an OFD to see if it's all good using.......verify!! Again, only load an OFD when in offline mode.

Once loaded here are some pointers:

Do an EC6/backup to ROM BEFORE you reset the PBX. I think the system automatically backs the new data up to ROM when the OFD restore finishes, but do it again to be sure. Then, still in offline mode, do an Office Data Conversion using command CM00>90:0. If you have upgraded the firmware on the CPU, this will ensure that any commands which have been replaced or superceded will be migrated to the new ones. Backup to ROM again.

Check and Change the time(it'll reset).

Test both an IP and TDM phone - the Dial tone/Hold/Ring etc maybe different, if so, you will need to go over and check your tone commands, and possibly, upload specific tone firmware onto your MP. I know in the UK we sometimes mistakenly (those silly boys!) were given Dutch firmware with different tones, which we had to manually over-write. DTG files must be loaded using an MP download with rotary switch on 8. You can also run in MACH editor a dial tone conversion script (if you have one) - changes won't occur til you ROM and reset).

IP phones tone may need to be changed manually. On modern firmware IP phones, you have a hidden menu where you have to set the Region to the local country tone. There also were some commands, I think to set it system wide - but I don't know for sure. To change to UK dial tone do doing the following (on an IP phone): Hold, Transfer, *, # Hold, #, 0 look for menu 3 Area ID when in Area ID, enter 8# until Uk is displayed. Save change and wait until phone boots up Check dial of IP phone. If everything checks out the create another OFD as a backup. Well done!
