==Physical ports==
The ATLB-12 provides 12 telephone lines. The 6 first telephone lines get the physical number according to the physical slot the ATLB-12 is but into. The 6 last telephone lines have an offset of 276 to 6 first physical numbers.

Example:
*ATLB-12 installed in slot 1 is using physical numbers 1-6 and 277-282.
*ATLB-12 installed in slot 2 is using physical numbers 7-12 and 283-288.
*ATLB-12 installed in slot 3 is using physical numbers 13-18 and 289-294.
* Etc.

==Switches==
The 3 DIP switches located on the ATLB-12 card are not relevant for the board’s performance since they are not implemented for use yet.
They are placed on the board for future use only.

==Software Requirement==
Minimum software requirement in AlphaCom: AMC 11.2.3.9

==Line Monitoring==
The ATLB-12 must be equipped with special software (05.51 or later) in order to support line monitoring. Note that when using ATLB-12 with line monitoring, there can be maximum 15 x ATLB-12 boards in one AlphaCom XE20 or XE26 module. In addition there can be 2 x ASLT boards and 1 x AGA board. For the line monitoring to work, the line must be terminated with an 8k2 resistor.

As the ATLB-12 software cannot be updated in the field, this must be done at the factory before the board is shipped. Please contact alphasupport@zenitel.com if line monitoring is required.
