2.5.1 I/O Module Slot Assignment
The device's front-panel chassis provides slots (numbered as shown in the figure below) for
housing the main input/output (I/O) interface modules (i.e., TRUNKS, BRI, FXS, FXO, and
MPM).
Figure 2-16: Mediant 1000 Front Layout
The guidelines for slot assignment for these modules, include the following:
„ The TRUNKS, BRI, FXS, and FXO modules must be housed in consecutive slots. In
other words, if the device houses three modules, then they must occupy slots 1, 2, and
3 (no skipping of slots).
„ It is recommended to assign the TRUNKS, BRI, FXS, and FXO modules to the slots
(starting from Slot 1) according to the order of priority listed below:
1. TRUNKS
2. BRI
3. FXS and/or FXO
