Each component emits synchronized STS frames with a time delay controlled by the timing
signal described in the “J0 Synchronization” section. These timing signals are indicated by the
arrows directed at the egress ports of each component.

(heavy data flow lines are P-TCBs; light data flow lines are S-TCBs; arrows to data flow lines are
timing controls).
12.13.3 Rules of Composition
No connections other than egress P-TCB to ingress P-TCB and egress S-TCB to ingress S-TCB
are permitted.
Each TSE fabric must have a central column (or multiple columns) of TSE devices through which
all traffic is switched.
All traffic must arrive at the central TSE column at the same time (with respect to STS-12
frames).
