Step 3 To display the current configuration of a line, enter the dspln -ds3 <X.line> command.
If you are configuring a MGX 8850 (PXM1E/PXM45) switch, replace X with 15 for an SRM in the upper
bay, or 31 for an SRM in the lower bay. If you are configuring a MGX 8830 switch, replace X with 7.
Replace line with the line number, which is in the range of 1 to 3 on an SRM-3T3/C card.
In the following example, the user displays the configuration for the T3 line connected to line 1 on the
SRM card in slot 7.
Lampoon.1.PXM.a > dspln -ds3 7.1
Line Number : 7.1
Admin Status : Up
Line Type : dsx3CbitParity
Line Coding : ds3B3ZS
Line Length(meters) : 1
OOFCriteria : 3Of8Bits
AIS c-Bits Check : Check
Loopback : NoLoop
Xmt. Clock source : localTiming
Rcv FEAC Validation : 4 out of 5 FEAC codes
Step 4 To configure a T3 line, enter the cnfln command as follows:
mgx8830b.1.PXM.a > cnfln -ds3 <slot.line> -lt <LineType> -len <LineLength> -oof
<OOFCriteria> -cb <AIScBitsCheck> -rfeac <RcvFEACValidation> -clk <clockSource>
Table 5-2 lists the parameter descriptions for configuring T3 lines.
Table 5-2 Parameters for T3 Line Configuration
Parameter Description
slot.line If you are configuring a Cisco MGX 8850 (PXM1E/PXM45) switch or an MGX 8880
Media Gateway, replace slot with 15 for an SRM in the upper bay, or 31 for an SRM in the
lower bay. If you are configuring a Cisco MGX 8830 switch, replace slot with 7.
Replace line with the number that corresponds to the back card port to which the line is
connected.
-lt T3 line type. Replace LineType with 9 to specify this line as a dsx3M23 line, or 11 to
specify the line as a dsx3CbitParity line.
-len Specifies the line length.
-oof Specifies Out of Frame (OOF) criteria. Replace <OOFCriteria> with 1 to specify a
criteria of 3 out of 8 frames, or replace it with 2 to specify a criteria of 3 out of 16 frames.
Note Option 2, 3 out of 16 frames, is the only option supported on SRME/B cards.
-cb Specifies the C-bit check. Replace <AIScBitsCheck> with 1 to check bits, or 2 to disable
a bits check.
Note Option 1, check C-bits, is the only option supported on SRME/B cards.
