Specifications: 1000 Kbps Bandwidth for Data Transfer, Remaining Bandwidth for Voice
Transmission
The 2 Mbps SDSL connection of an HXGM3 board (HiPath 3750 or HiPath 3700) is to enable
duplex data transmission at 1000 Kbps. The average packet size is 500 bytes. In addition, the
SDSL connection for IP Networking connections with G.729 and a sample rate of 20ms should
be used.
Performance Requirements for SDSL Connection
Calculation of the dynamic performance requirement for the SDSL connection based on the re-
quired data exchange rate ( 1000kbps = (1000 x 1000)/8 bps = 125000 bps per route). The fol-
lowing formula applies for 500 byte packet length:
Number of possible simultaneous IP networking connections
A performance requirement of 595 points is specified for the SDSL connection. Since the
HXGM3 board can provide total performance of 980 points, 385 performance points are avail-
able for IP networking connections.
