ADTRAN 1200305L1 system manual Allows configuration of parameters for each Dlci

Section 4, User Interface Guide ATLAS 550 System Manual

DLCI

Write security: 3; Read security: 5

Local address for each PVC as assigned by the carrier.

QOS

Write security: 3; Read security: 5

Quality of service. These values can be used to assign a guaranteed amount of bandwidth available for this connection. The sum of all QOS values for the sublink should not exceed the Committed Information Rate (CIR).

BURST

Write security: 3; Read security: 5

Sets the burst rate used by this virtual circuit for data traffic. A value of zero means that the burst rate is not limited. The value is in kilobits/second. If voice traffic is flowing on ANY sublink on the port carrying THIS sublink, you should enter a value for this setting. Otherwise, leave this field set to default (zero). If the service provider has supplied a 'Be' value, enter that value in this field. The burst rate defines the amount that this virtual circuit is allowed to exceed the CIR. If the service provider has not supplied an excess burst rate, enter the wire speed in this field.

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.
