For example, if the device requires one TRUNKS module and two FXS modules, then
you must insert the TRUNKS module in Slot 1 and the two FXS modules in slots 2 and
3 respectively. If at a later stage, you wish to add a BRI module (for example), then
you must replace the FXS module in Slot 2 with the new BRI module, and then re-
insert this replaced FXS module in Slot 4.
The figure below displays an example illustration of correct module slot assignment:


The MPM module provides IP media channels for applications such as
announcements, conferencing, SBC, and IP-to-IP call routing:
•
When no other modules are used, up to three MPM modules can be housed in
the device.
•
For conferencing, one MPM module must be housed in Slot 6, providing 20 media
channels. For additional media channels, you can add MPM modules to slots 4
(40 channels) and 5 (40 channels) as well, thereby providing a total of 100 media
channels for conferencing.
•
For applications other than conferencing (e.g., SBC, IP-to-IP routing, and
announcements), the MPM modules can be housed in slots 3, 4, and 5. Each
module provides 40 channels; thereby, providing a total of 120 channels (60 for
IP-to-IP call sessions).
•
The device can acquire additional media channel resources (for SBC, IP-to-IP
routing, and conferencing) from the TRUNKS modules. For a description of this
configuration, refer to the device's
User's Manual .
6.1.2 Removing Kapton Tape before Installing Modules
The following modules are supplied with Kapton tape covering their gold fingers (i.e., edge
of the module):

FXS, FXO, BRI, and TRUNKS (PRI)

CMX and CRMX

HDMX (OSN3 hard drive)

Fan

Power Supply
The Kapton tape is used to protect the module's BUS line. Before installing a new module,
you must remove this Kapton tape. If not removed, the module may not be functional,
chassis operation may be compromised and irreversible damage may be caused to the
chassis.
The figure below shows an example of a module with the Kapton tape over the gold finger:
