OC-192 Module Connections
Table 3-11 shows the OC-192 specifications for use with the 1-Port OC-192c/STM-64 POS/RPR XFP
SPA.
Note The RPR mate cable is only necessary when the SPA is to be used in RPR mode. It is not needed in POS
mode. Support for the RPR feature is dependent on the platform software release feature content. Verify
support for the RPR feature support via SPA datasheets or by contacting your Cisco representative.
