UTO
Passes the state as reported by the frame relay switch. Set DLCI
S to A for normal operation.
TATE UTO
F
ORCE UP
This DLCI disregards the status as reported from the switch and
reports A to all packet endpoints within the ATLAS 550.

ORCE DOWN
Reports status as D
550.

CHO AR ND
Generates and transmits a response on this DLCI to the remote
equipment if an ADTRAN proprietary diagnostic message is
received on this DLCI.
I -B D
N AND ELAY
Generates a diagnostic packet to measure delay through the frame
relay network. This process requires that the equipment at the
remote site be ADTRAN IQ compatible.
P -T
ASS HROUGH
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.
Assume the following sublink packet endpoint is connected to the frame re-
lay network via a full T1:
Name DLCI QOS
Atlanta 903
New York 805
San Francisco 615
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.
