7.3 Cross-Connect Card Bandwidth

The single shelf cross-connect card (SSXC) cross-connect cards perform port-to-port, time-division
multiplexing (TDM). The STS matrix has the capacity for 6144 STS terminations. Because each STS
circuit requires a minimum of two terminations, one for ingress and one for egress, the SSXC has a
capacity for 3072 STS circuits. However, this capacity is reduced at path protection and 1+1 nodes
because three STS terminations are required at circuit source and destination nodes and four
terminations are required at 1+1 circuit pass-through nodes. Path Protection pass-through nodes only
require two STS terminations.
