Please adhere to the following guidelines for slot assignment of these modules:

■ TRUNKS (PRI), BRI, FXS, and FXO Modules:
● The modules can be housed only in slots 1, 2, 3, 4, 5 and 6.
● The modules must be housed in consecutive slots. In other words, if the device houses three modules, they must occupy slots 1, 2, and 3 (no skipping of slots).
● It is recommended to house the modules starting from Slot 1 and according to the order of priority listed below:
i. TRUNKS
ii. BRI
iii. FXS and/or FXO

For example, if you need one TRUNKS module and two FXS modules, you must install the TRUNKS module in Slot 1 and the two FXS modules in Slot 2 and Slot 3. However, if at a later stage you wish to add a BRI module, you must remove the FXS module from Slot 2 and insert it in Slot 4, and then insert the BRI module in Slot 2, as shown in the following figure:

■ MPM Module: The module provides additional DSP resources for applications such as three-way conferencing and SBC transcoding:
● MPM modules can be housed only in slots 1, 2, 3, 4, and 5. It is recommended to house the MPM modules starting from the last slot (i.e., Sot 5) toward the first slot. For example, if you want to use 4 MPM modules, house the MPM modules in slots 2, 3, 4, and 5. For information on the number of media channels (DSP resources) provided by the MPM modules per slot, refer to 'DSP Channel Resources for Transcoding' section in the User's Manual.
● The device can acquire additional media channel resources (for SBC transcoding) from the TRUNKS modules. For more information, refer to the 'DSP Channel Resources for Transcoding' section in the User's Manual.
