menu:
Signal Type (SIGNAL)
Set the signaling type option to match the network signaling type.
A
UTO
mode forces the TSU IQ+ to use the same signaling type as
the attached frame relay DTE. If A
UTO
is selected and there is no
DTE device attached, the TSU IQ+ uses ANSI T1.617-D signaling
type.
Choices:

ITU-T Q.933-A (Annex A), or A
UTO
.
T391
Set the time (in seconds) between polls to the frame relay network.
Range:
5 to 30 seconds.
N391
Determine how many link integrity polls occur in between full
status polls.
Range:
1 to 255 .
N392 and N393
These parameters define the error threshold for the UNI formed by
the TSU IQ+
Network
port and the frame relay switch. If the error
threshold is met, the signaling state status is changed to down,
which indicates a service-affecting condition. This condition is
cleared once N393 consecutive error-free events are received. N392
defines the number of errors required in a given event window,
while N393 defines the number of polling events in each window.
For example:
If N392=3 and N393= 4, then if three errors occur within any four
events the interface is determined inactive.
