Front Cards
MPSM-T3E3-155
Supported models: MGX 8850 (PXM1E/PXM45), MGX 8850/B (PXM1E/PXM45), MGX 8830, MGX 8830/B
The MPSM-T3E3-155 (Multi-Protocol Service Module) is a single-height multiprotocol service module.
This card is a cell-bus based service module with OC-3 capacity. The card implements multiple protocols
(ATM, including IMA, and Frame Relay) on the same board, achieved by performing most of the data
processing in software. Thus it provides any service, any port (ASAP) support, and can support
broadband and narrowband ports simultaneously.
Designed as a replacement for the existing AXSM and FRSM12 service modules (FRSM-2T3E3and
FRSM-2CT3 front cards), the MPSM-T3E3-155 card is an Any Service Any Port (ASAP) service
module that supports multiple interface types (OC3, T3 and E3, and channelized T1, E1, VTs, and DS0s)
and two service types (ATM and Frame Relay).
Table 2-18 lists the different MPSM-T3E3-155 back card types, along with the number of lines, number
of connections, number of SPVCs, number of SVCs, and SFPs (if applicable) supported by each back
card.

1. Replaceable transceivers called Small Form Factor Pluggable (SFP) units. 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.
