Note
You can replace STSs for VTs at the following rates:
Add 48 VT 1.5s at the cost of two STS-1s. If all the high order (HO) circuits are VCAT, one additional
STS-1 is lost. Alternatively, you can add 48 VT 1.5s at the cost of two STS-3cs. If all the HO circuits
are VCAT, one additional STS-3c is lost.
In some cases, circuits can be added by reducing the circuits for other concatenation rates.
