Chapter 6. DTE Port Configuration
Minimum Poll Timer (MIN POLL TIME)
This parameter defines the minimum time (in milliseconds)
between consecutive polls to a given PU assigned to the DTE port.
Slow Poll Ratio (POLL RATIO)
Determine how often devices on the Slow Poll list are polled. This
list is automatically managed based on poll timeouts. Initially, all
PUs are on the Normal list. When a PU times out a fixed number
of times, it is moved to the Slow Poll list. A PU remains on this list
until it responds properly to a poll.
The number entered is the number of times PUs on the Normal list
are polled before PUs on the Slow Poll list are polled. Enter 1 to
disable this option.
Disconnect Threshold (THRESHOLD)
Set the maximum number of response timeouts allowed before a
session is terminated.
Transmit Delay (TX DELAY)
Set the minimum time between transmission frames.
CTS Option
Set the Express 5200 CTS O

.

Data Format (FORMAT)

When using NRZI format, the Express 5200 does not derive timing
from the receive data input.
