7.2 How to Estimate Bandwidth Requirements and Configuration Limits
7.2.1
Bandwidth Requirements
Application Server and KCS Line Server are linked via a TCP/IP connection
– either local 10/100Base/T or
WAN connection in case of a BranchBox.
Line Server
Bandwidth
30kBit/s per fax channel
70kBit/s per voice or mixed fax/voice channel
Round Trip Time
1000msec (256Byte block size)
BranchBox
Bandwidth
30kBit/s per fax channel
Round Trip Time
1000msec max.
Tandem Application Server (distributed system)
Entry Level Systems (up to 6 FAX lines, max. 5 client/server channels, max. 1Link):
Bandwidth > 1Mbit/sec
Packet Round Trip Time < 50msec
High End Systems (60 Fax-lines and above):
Bandwidth > 5Mbit/sec
Packet Round Trip Time < 10ms
The values given above are minimum requirements for proper operation of the Fax channels. At high
system loads interactive clients such as TCfW might suffer from increased response times.
