Definition
Type in the information rate, excluding error correction bits and syn-
chronization patterns for the given channel.
Type in for each channel.
Select the modulation scheme for each channel: QPSK, 8PSK.
Select the Forward Error Correction code rate for each channel
Select the maximum acceptable bit error rate (BER) for this channel.
By default all parameters defined for channel 1 are copied to all ad-
ditional channels.
If in this box 'Yes' is selected, the specified data from channel 1 is
used.
Select the appropriate codec used for voice over SkyWAN FAD. Fac-
tor x1, x2, x3 specifies the quantity of voice packets per frame.
Type in the fraction of the user data traffic in percent used for Frame
Relay voice traffic.
Type in the average packet size in byte of Real-time Frame Relay
traffic.
Type in the fraction of the user data traffic used for Frame Relay
Real-time traffic.
Type in the average packet size in byte of Non Real-time Frame Re-
lay traffic
Type in the fraction of the user data traffic used for Frame Relay Non
Real-time traffic.
Select the appropriate codec used for voice over IP.
If no codec is selected in the field above, type in the average IP pack-
et length for the VoIP data.
Type in the fraction of the user data traffic used for VoIP traffic.
Type in the average packet size in byte of IP Realtime traffic (exclud-
ing Voice over IP)
Type in the fraction of the user data traffic used for IP Realtime traffic
(excluding Voice over IP).
Type in the average packet size in byte of IP Non-Realtime traffic
Type in the fraction of the user data traffic used for IP
Non-Realtime traffic.
