1-Port OC-192c/STM-64 POS SPA Overview
•
Mate between two OC-48c SPAs in adjacent SIPs
Two 1-Port OC-48c/STM-16 POS SPAs are connected using a 40–pin connector copper mate cable. The
length of the cables allow only two possible connection scenarios, next slot horizontal and same slot
vertical. This assumes that the chassis is mounted vertically.
Figure 2-23
shows the mate cables used to
connect the SPAs.

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 by reviewing the relevant SPA datasheets or by contacting your
Cisco representative.
