Performance Characteristics - AT&T IPC-1600 User Manual

Performance Characteristics

The IPC-1600 supports the following bit per second rates: 38400, 19200,
9600, 4800, 2400, 1800, 1200, 600, 300, 200, 150, 134.5, 110, 75, and 50.
The performance of the IPC-1600 expressed in terms of line occupancy at
a prescribed baud rate in the raw and cooked modes with no flow control is as
follows. In the cooked mode, canonical processing is enabled. In the raw
mode, canonical processing is disabled. The line occupancy formula is:
Line Occupancy (%) =
The line occupancy formula may have results greater than
Note:
100%. This is reserve capacity that is NOT achievable. The
following line occupancy results are typical of an
AT&T 6386E/33 WGS Model S with one IPC-1600 board.
The input capacity of the IPC-1600 is determined by the number of lines
(ports) simultaneously operating at 100% occupancy with no flow control as
follows.
