如何转换STM-1（signal）到Virtual Tributary 1 (signal)
1 STM-1（signal） = 90 Virtual Tributary 1 (signal)
1 Virtual Tributary 1 (signal) = 0.0111111111 STM-1（signal）
示例: 将 15 STM-1（signal） 转换为 Virtual Tributary 1 (signal)：
15 STM-1（signal） = 15 × 90 Virtual Tributary 1 (signal) = 1350 Virtual Tributary 1 (signal)
