ORCE UP
This DLCI disregards the status as reported from the switch and
reports

Reports status as

ACKETS
Used when the ATLAS 550 is acting as a frame relay switch. Trans-
mits a diagnostic packet out the packet endpoint connected to this
DLCI, if a diagnostic packet is received on this packet endpoint.
Sublinks Example
Assume the following sublink packet endpoint is connected to the frame re-
lay network via a full T1:
If the PVC to San Francisco needs to transmit data, it will be able to access
the network at full T1 rates. If, at the same time, data needs to be transmitted
to the PVC to New York, the San Francisco and New York PVCs would
equally share the T1 to the frame relay provider because they have the same
QOS value. If, also at the same time, data needed to be transmitted to the At-
lanta PVC, the T1 would be divided three ways: traffic to Atlanta gets half of
the T1, and the New York and San Francisco PVCs equally share the remain-
ing half of the T1, since they share the same QOS value.
