MPSM Card Types
• MPSM Card Features
On the Cisco MGX 8850 (PXM1E/PXM45) and Cisco MGX 8830 (PXM1E/PXM45) switches, the PXM card is the controller card that controls the other cards on the switch. The other cards on the switch are called service modules. MPSM-T3E3-155 and MPSM-16-T1E1 cards are service modules. MPSM stands for Multi Protocol Service Module.
The main function of the MPSM-T3E3-155 and MPSM-16-T1E1 service modules is to provide simultaneous ATM and Frame Relay services over unchannelized, channelized and fractional (T1/E1) interfaces whose speed ranges from OC-3/STM-1 to a single DS0 (Fractional). Both cards let you configure individual physical ports for ATM or Frame Relay services. Additionally, the MPSM-16-T1E1 card supports MLPPP services.
The PXM cards are not covered in this manual. For information about the PXM cards, refer to the following documents:

•Cisco MGX 8800/8900 Series Command Reference, Release 5.2

MPSM Card Types
The MPSM-T3E3-155 is a single-height front card that accommodates one single-height back card. The MPSM-T3E3-155 front card supports both OC-3 (155) and T3/E3 interfaces, depending on which back card it is installed with.
The MPSM-16-T1E1 is a single-height front card that accommodates one single-height back card. The MPSM-16-T1E1 front card supports both T1 and E1 interfaces, depending upon which back card it is installed with.
Table 1-2 provides an overview of the MPSM-T3E3-155 and MPSM-16-T1E1 cell bus service modules documented in this manual. Note that the SFP-2-155 back card requires replaceable transceivers called Small Form Factor Pluggable (SFP) units. The SFPs are hot-pluggable, and the MPSM-T3E3-155 software detects the removal and insertion of the SFP. This means that you can remove and insert an SFP at any time without affecting the front card status. You can replace one type of SFP with a different type of SFP without causing a mismatch (for example, you can replace an MMFSR-1-155-SFP with an SMFLR-1-155-SFP). You can not replace a supported SFP with an unrecognized (non-supported) SFP.
Note For specifications and illustrations of the MPSM-T3E3-155 card and the supported SFPs, see the Cisco MGX 8800/8900 Hardware Installation Guide, Releases 2 - 5.2
Note For specifications and illustrations of the MPSM-16-T1E1 card, see the Cisco MGX 8800/8900 Hardware Installation Guide, Releases 2 - 5.2.

The preferred tools for configuring, monitoring, and controlling service modules is the Cisco WAN Manager application for equipment management and connection management. However, the command-line interface (CLI) also provides access to the service modules and is highly applicable during initial installation, troubleshooting, and any situation in which low-level control is useful.
