CHAPTER6 Hardware Maintenance
Mediant 1000 Gateway & E-SBC | Hardware Installation Manual
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.
