FXS+ Dual Voice Module (Software Revision K and
above) can only be fully supported in TSU 100 units of
Software Revision L (and later) and TSU 600 units of
Software Revision F (and later). To determine the
software revision in the TSU, follow these steps:
1. Power the TSU On.
2. Using the front panel keypad, select Main menu item
3 (UTIL) which gives you the Utility menu.
3. From the Utility menu, select menu item 5 (Software
Revision).
4. The unit will display the revision of the operating
software.
If the card is to be installed in a TSU 100 or TSU 600
with an earlier software revision, ADTRAN recommends
that the TSU first be upgraded to the most recent
revision to ensure proper operation with the FXS+. For
assistance with software revision upgrades, please
contact ADTRAN Technical Support at
1-800-726-8663.
Before installing the module, check the back panel for the
presence or absence of a Hot Replaceable label on the back
panel
For ease of replacement, power to the TSU 100/600 may
be On when installing or removing the FXS+ Dual Voice
option module with a Hot Replaceable label on the back
panel .
