Signal Type (SIGNAL)
Set this option to match the network signaling type. The choices are
N
ONE
,
LMI
(gang of four),
ANSI T1.617-D
(Annex D), and
ITU-T
Q.933-A
(Annex A).
T391
Set the time between polls to the frame relay network.
N391
Determine how often full status polls occur in relation to link
integrity polls.
For example:
If N391=6, then five link integrity polls will be followed by a full
status poll.
N392 and N393
These parameters define the error threshold for the UNI formed by
the Express 5210 network port and the frame relay switch. If the
error threshold is met, the signaling state status is changed to
D
OWN
, 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 when three errors occur within any
four events the interface is determined inactive.
For point-to-point DDS operation, the
S
IGNAL
T
YPE
should be set to
N
ONE
.
