UTO

Passes the state as reported by the frame relay switch. Set DLCI

TATE

to A

UTO

for normal operation.

ORCE UP

This DLCI disregards the status as reported from the switch and

reports A

CTIVE

to all packet endpoints within the ATLAS 550.

ORCE DOWN

Reports status as D

OWN

to all packet endpoints within the ATLAS

550.

Generates and transmits a response on this DLCI to the remote

EASUREMENT

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.

IAGNOSTIC

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 followingsublink packet endpointis connectedto 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

thenetwork atfullT1rates. If,atthe sametime,dataneedsto be transmitted

to the PVC to New York, the San Francisco and New York PVCs would

equally share theT1 tothe frame relay provider because they have thesame

QOS value.If, also atthe same time, data needed tobe transmitted totheAt-

lantaPVC, theT1would bedivided three ways:trafficto Atlantagets halfof

theT1, andtheNewYorkandSanFranciscoPVCsequallysharetheremain-

ing half of the T1, since they share the same QOS value.
