Chapter 6. DTE Port Configuration
Protocol Options
4 4
Signaling Type (SIGNAL)
Set the signaling type for the DTE port to match the signaling
type of the connected DTE device. Choices are none, FRF LMI,
ANSI T1.617-D, and ITU-T Q.933-A. If none is chosen, the
signaling state for the DTE port is always up.
T392
Set the timeout between polling intervals. This parameter needs
to be a few seconds longer than the T391 setting of the attached
frame relay device.
N392 and N393
These parameters define the error threshold for the UNI formed
by the FSU DTE port and the attached frame relay device. 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.
The status of the connection can be viewed in the Status menu
under DTE Port Signaling State. The status will return to active
once the threshold is no longer exceeded.
Guidelines for Configuring IP Addr, Subnet Mask, and Mng DLCI
If the attached router or FRAD is used to route SNMP/telnet
frames to the FSU, set the Management DLCI to a unique value
that identifies the virtual circuit between the router/FRAD and
the FSU. The router/FRAD must also be configured to route the
FSU IP address to this DLCI. The IP address and subnet mask
for the DTE port must also be set.
