shows the OC-48 specifications for use with the 2-Port and 4-Port OC-48/STM-16 POS SPA.

Mate Interface Cables

The 2-Port and 4-Port OC-48/STM-16 POS SPA supports two mate interface configurations:

Mate between two OC-192 SPAs in the same SIP

Mate between two OC-192 SPAs in adjacent SIPs

Two 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 2-46 shows the mate cables used to connect the SPAs.
