Chapter 5 Preparing SRM Cards for Communications
Setting Up SRM Lines
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 <

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. Replace <LineLength> with a
number to specify 0 through 64000 meters.
-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.
