Eicon Networks 1550 - Manual (Page 112)

Web Interface Settings Glossary 112
Full status polling cycle (N1)
Defines the number of polling cycles before a Full Status Report is requested. A
polling cycle is a Status Enquiry and Status message exchange. This setting
determines the time the user device takes to recognize a change in status on a DLCI
from the Frame Relay network. This may include the addition or deletion of a DLCI by
the network.
Range: 1-255.
Default: 6.
Error threshold (N2)
Defines the maximum number of Reliability Errors and/or Protocol Errors that can
occur during a sliding Monitored Events Count, before a Frame Relay connection is
declared inactive. This parameter should always be less than or equal to the Monitored
Events Count.
Range: 1-10.
Default: 3.
Monitored events count (N3)
Defines the Monitored Events Count, which is the number of successful polling cycles
required before the Frame Relay port can be declared active. If the port has been
declared inactive, the network waits the specified number of monitored events before
declaring it active again.
Range: 1-10.
Default: 4.
Note: Note: For a DLCI to be declared inactive, the amount defined for N2 (Reliability Errors and/or Protocol
Errors) must be reached within the specified number of monitored events. This prevents transient conditions
from declaring a DLCI inactive.
Link integrity verification timer (T1)
Defines how frequently the Eicon 1530 WAN Router should initiate a Status Enquiry
message. This timer must be set to less than the timer used by the Frame Relay
Network to verify that the Eicon 1530 WAN Router is sending Status Enquiry
messages. To determine the Frame Relay Network timer value, contact your network
administrator.
Possible values: 5, 10, 15, 20, 25, 30 (seconds).
Default: 10 seconds.
Committed information rate
Defines the Committed Information Rate (CIR) in bits per second. The CIR is the rate
at which the network transfers information under normal conditions. The service
provider typically sets pricing based on the CIR (including other criteria) with rate
guarantees.
Range: 2400-2048000.
Default: 9600.
