IMATM Clock Configuration Parameters

IMATM Port Configuration

Use this dialog to view port configuration parameters for the IMATM card. The parameters are described in Table 11-4.

Table 11-4: IMATM Port Configuration

Parameter Description

IMAPort State

IMA port state. Choose noAction or resetCounters from the popup menu.

IMAPort Number

The logical port number.

IMAPort Enable

Modifies, enables, or disables the configuration of the port. Choose one from the pop-up menu:

delport

addport

addlinks

dellinks

modify

IMAPort Speed

Speed of the port in cells per second.

numLinksInImaGrp

Number of links configured in the IMA group.

listOfLinksInImaGrp

List of links in the IMA group delimited by dots.

Period LCP Cells Tx

Period at which LCP cells of the IMA protocol can be transmitted. A value of 32 indicates that after 32 cells, one LCP cell is transmitted on that link of the IMA group. Currently, the only value supported is 128.

LCP Delay Tolerance

Number of IMA frames for which an LCP cell on any link can be missed before the IMA state machine should remove the link from the IMA group.

readPtrWrPtrDiff

Difference between the read and write pointer of a link in the common cell buffer. A lower value reduces the latency in the common cell buffer but also increases the probability of an IMA group being stalled for a cell-time due to a slower link in the IMA group.

Degree of Resiliency in IMA Grp

Degree of resiliency in the IMA group. This indicates the number of links the system can lose from this IMA group without bringing it down.

Max. Tolerable Diff. Delay

Indicates the maximum tolerable differential delay in milliseconds between the various links in the IMA group. The default value is 50 milliseconds for an IMA group consisting of either T1 or E1 lines.

imaPortType

Indicates whether or not the port is to be configured for UNI/NNI/STI mode. Choose one from the pop-up menu:

uni

nni

sti

vpTrkUni

remoteImaId

Indicates the IMA-ID in use at the remote end when sending LCP/ACP cells.

locImaId

Indicates the IMA-ID in use at the local end when sending LCP/ACP cells.

imaObsDiffDelay

Observed differential delay in milliseconds between the different physical links in the IMA group. This object does not have any default value
