Dynamic Configuration Rules
Performance requirement for the Media Gateway (= Gateway HG 1500)
Calculation of the dynamic performance requirement for the DSL connection on the basis of the
highest throughput rates (upstream = 192 Kbps = (192 x 1000) / 8 bps = 24000 bps, Down-
stream = 2048 Kbps = (2048 x 1000) / 8 bps = 256000 bps). The following formulae apply for
1400 byte packet length:
The specified performance requirement of 738.0 points is below the 980 total performance
points that the HXGM3 board can provide. The configuration is feasible.
Upstream: Downstream:
24000 bps 256000 bps

DSL connection (without encryption with 1400 bytes packet length,
performance requirement (score) = 96 for 100 packets/sec):
17 packets/sec upstream (192 kbps)
17 x (96 / 100) = 16.32
183 packets/sec downstream (2048 kbps)
183 x (96 / 100) =
175.68

14 x 39.0 = 546.0
Total =
