OM20 Universal Outdoor Modem
Example 2b:
Change to E1-PCM30 framing (E1 Signaling), standard ES to ES overhead
Add 10 * 2000 bps to our previous calculation gives 662500 bps
Still saving over 20,000 bps compared to the open network standard.
Example 2c:
Change to Enhanced Async with In-Band Baud Rate of 1200
X = Truncation of (1200 / (10 * 125)
X = Truncation of (0.96)
X = 0
The rate stays at the previous value of 662500
With 10 slots, there is no increase required to carry 1200 baud Enhanced Async. It is passed
transparently in the Efficient Drop & Insert overhead.
