Release 1.1.31, Part Number 78-11215-03 Rev. B0, May 2001
Chapter 1 Introducing the MGX 8230
Summary of MGX 8230 Cards and Modules
User Interface Back Cards
• Processor Switch Module User Interface (PXM1-UI)
The PXM1-UI is the user interface card that has various types of user access used to control and
configure the 8230.
• Processor Switch Module User Interface (PXM-UI-S3)
The PXM-UI-S3 is an optional user interface card that has various types of user access used to
control and configure the 8230. This card also provides Stratum 3 clocking capability.
OC-3 Uplink Back Cards
• MGX-MMF-4-155/B (multi-mode fiber uplink back card)
The MGX-MMF-4-155/B is a broadband network module for the PXM1 and provides four SONET
OC-3/STM-1 ATM interfaces at 155 Mbps.
• MGX-SMFIR-4-155/B (single-mode fiber intermediate reach uplink back card)
The MGX-SMFIR-4-155/B is a broadband network module for the PXM1 and provides a
single-mode, intermediate-reach, fiber optic SONET OC-3 interface that conforms to ANSI T1.105
and GR-253-CORE standards. This interface uses SC connectors. Redundant configurations are
supported through SONET automatic protection switching (APS) functionality (APS requires the
“B” model).
• MGX-SMFLR-4-155/B (single-mode fiber long reach uplink back card)
The MGX-SMFLR-4-155/B is a broadband network module for the PXM1 and provides a
single-mode, long-reach, fiber optic SONET OC-3 interface that conforms to ANSI T1.105 and
GR-253-CORE standards. This interface uses SC connectors, and redundant configurations are
supported through SONET Automatic Protection Switching (APS) functionality (APS requires the
“B” model).
OC-12 Uplink Back Cards
• MGX-SMFIR-1-622
The MGX-SMFIR-1-622 is a broadband network module for the PXM1 and provides a SONET
OC-12/STM-4 ATM interface at 622 Mbps. Automatic Protection Switching (APS) requires the “B”
model (SMFIR-1-622/B).
• MGX-SMFLR-1-622
The MGX-SMFLR-1-622 is a broadband network module for the PXM1 and provides a SONET
OC-12/STM-4 ATM interface at 622 Mbps. Automatic Protection Switching (APS) requires the “B”
model (SMFLR-1-622/B).
T3/E3 Uplink Back Cards
• MGX-BNC-2T3
The MGX-BNC-2T3 is a broadband network module for the PXM1 and provides two T3 ATM
interfaces.
• MGX-BNC-2E3
The MGX-BNC-2E3 is a broadband network module for the PXM1 and provides two E3 ATM
interfaces. Two versions of the BNC-2E3 card are available. The BNC-2E3A applies to Australia
only. The BNC-2E3 applies to all other sites that require E3 lines on the PXM1 uplink card.
