User Guide: PTP 600 Series
Calculation procedure and example
Procedure
To calculate the data rate capacity of a PTP 600 link, perform
Procedure 4-1 Calculating data rate capacity
1
Use the tables in
up the data throughput capacity rates (Tx, Rx and Both) for the
required combination of:
2
The tables contain data rates for PTP 600 Full only. If the ODUs
are PTP 600 Lite, divide the data rates by 2.
3
The tables contain data rates for links of zero range. Use the
curves in
Throughput Factor that must be applied to adjust the data rates
for the actual range of the link.
4
Multiply the data rates by the Throughput Factor to give the
throughput capacity of the link.

There is a small difference between the rates for IP and TDM because there
is fragmentation in TDM (for low priority traffic) which causes the
throughput to be reduced buy approximately 1% compared to the IP mode.
