AUTO
Passes the state as reported by the frame relay switch. Set DLCI
STATE to AUTO for normal operation.
FORCE UP
This DLCI disregards the status as reported from the switch and reports ACTIVE to all packet endpoints within the ATLAS 550.
FORCE DOWN
Reports status as DOWN to all packet endpoints within the ATLAS 550.
DIAGNOSTIC MODE
Controls operation of PVC testing options. To allow the far end to mea- sure delay, select ECHO
ECHO
Generates and transmits a response on this DLCI to the remote equipment if an ADTRAN proprietary diagnostic message is received on this DLCI.
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.
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:
Name | DLCI | QOS |
Atlanta | 903 | 768 |
New York | 805 | 384 |
San Francisco | 615 | 384 |
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.
