Introduction to Core Card Sets and Service Modules

The MGX 8230 supports core cards and service modules. The Processor Switching Module (PXM1) and
optional Service Resource Module (SRM) are core cards.
In addition, the PXM1 is part of a card set consisting of a front card, a back card, and a daughter card:

•
•
Service modules are not combined in this manner and are never part of a card set. Instead, service
modules provide the interface for transport technologies such as Frame Relay and ATM.
The MGX 8230 enclosure contains up to 8 service modules (I/O cards). The optional Service
Redundancy Modules (SRMs) provide redundancy.
Although technically distinct, he terms card and module are often used interchangeably in the field.

The front card contains the processing intelligence.
The daughter card contains the firmware that distinguishes the interface (OC-3, T3, E3, and so on).
The back card is a simple card that provides the electrical interface for one or more lines of a
particular type.
Processor Switching Module (PXM1)
This front card controls the 8230 and supports external interfaces for user-access and trunking or
UNI ports. The back cards consist of a user interface card and a broadband network module.
