8.9    MXP_MR_2.5G and MXPP_MR_2.5G Cards
Note In Software Release 7.0 and later, two additional operating modes have been made available to the user: 
pure ESCON (all 8 ports running ESCON), and mixed mode (Port 1 running FC/GE/FICON, and Ports 
5 through 8 running ESCON). When the card is part of a system running Software Release 6.0 or below, 
only one operating mode, (FC/GE) is available for use.
The 2.5-Gbps Multirate Muxponder–Protected–100 GHz–Tunable 15xx.xx-15yy.yy (MXPP_MR_2.5G) 
card aggregates various client SAN service client inputs (GE, FICON, Fibre Channel, and ESCON) into 
one 2.5 Gbps STM-16/OC-48 DWDM signal on the trunk side. It provides two long-reach 
STM-16/OC-48 ports per card and is compliant with ITU-T G.957 and Telcordia GR-253-CORE.
Because the cards are tunable to one of four adjacent grid channels on a 100-GHz spacing, each card is 
available in eight versions, with 15xx.xx representing the first wavelength and 15yy.yy representing the 
last wavelength of the four available on the card. In total, 32 DWDM wavelengths are covered in 
accordance with the ITU-T 100-GHz grid standard, G.692, and Telcordia GR-2918-CORE, Issue 2. The 
card versions along with their corresponding wavelengths are shown in Table 8-22.
The muxponders are intended to be used in applications with long DWDM metro or regional 
unregenerated spans. Long transmission distances are achieved through the use of flat gain optical 
amplifiers. 
The client interface supports the following payload types: 
 • 2G FC
 • 1G FC
 • 2G FICON
 • 1G FICON
 • GE
 • ESCON
Note Because the client payload cannot oversubscribe the trunk, a mix of client signals can be accepted, up to 
a maximum limit of 2.5 Gbps.
