Section 4 User Interface Guide ATLAS 550 System Manual
CONFIG
Write security: 3; Read security: 5
Allows configuration of parameters for each DLCI.
FRAGMENTATION THRESHOLD
Write security: 3; Read security: 5
Max packet size allowed on this PVC. A zero value disables fragmentation. Fragmentation is
used to improve the quality of voice transmission. A good value is R/300, where R is the smallest
of the ATLAS 550 link rates or the far end link rate in bits per second. For example, if a DLCI
comes from an FSU 5622 running on a 56K DDS line and is delivered to the ATLAS 550 on a
full T1, the lower rate is 56000 and the value is 186 or 187. Entered values between 1 and 127 are
adjusted upward.
DLCI STATE
Write security: 3; Read security: 5
Controls how the state of this DLCI is reported to any packet connections within ATLAS 550
attempting to send or receive data on this DLCI.
AUTO Passes the state as reported by the frame relay switch. Set DLCI
STATE to AUTO for normal operation.
FORCE ACTIVE This DLCI disregards the status as reported from the switch and
reports Active to all packet endpoints within ATLAS 550.
FORCE INACTIVE Reports status as DOWN to all packet endpoints within ATLAS 550.
DIAGNOSTIC MODE
Write security: 3; Read security: 5
Controls operation of PVC testing options. To allow the far end to measure delay, select ECHO
FAR-END LOOPBACKS. To continuously measure in-band delay, select IN-BAND DELAY
MEASUREMENT. To turn off continuous diagnostic functions, select PASS-THROUGH DIAGNOSTIC
PACKETS.

DIAGNOSTIC PACKETS
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 ATLAS 550 is acting as a frame relay switch.
Transmits a diagnostic packet out the packet endpoint connected
to this DLCI, if a diagnostic packet is received on this packet
endpoint.
