Chapter 4 Configuring VISM Features
Configuring VISM Features
Note The y argument value is the actual slot number of the VISM card. Always type 1 for port
argument value, which represents the line number in this configuration. VISM-PR cards
do not have this requirement.
Step 3 Type the cnfln command, the line-num, line-code, line-length, clock-source, line-type, and
loop-detection argument values, and press Enter to configure the clocking option defined in Step 2 on
your VISM card. Specify the arguments with the following values:
• line-num: In the range from 1 to 8
• line-code:
–
2 = B8ZS for T1
–
3 = HDB3 for E1
–
4 = AMI for T1 or E1
• line-length:
–
8 = E1 lines with AX-SMB-8E1 and AX-R-SMB-8E1 back card types
–
9 = E1 lines with AX-RJ48-8E1 and AX-R-RJ48-8E1 back card types
–
In the range from 10 to 15 = T1 lines
• clock-source:
–
1 = Loop clock—clocking from the T1 or E1 line
Note If the clocking source is from a line on your VISM card, you must configure that
line—which must be line 1—as loop clock. Configure all remaining lines on all
remaining VISM cards as local.
–
2 = Local—clocking from the PXM card
Note You must configure all lines on all VISM cards as local if the clocking source to the
VISM cards is from the PXM card.
• line-type:
–
1 = DSx1ESF
–
2 = DSx1D4
–
3 = E1
–
4 = E1CRC
–
5 = E1MF
–
6 = E1MFCRC
–
7 = E1 clear
• loop-detection:
–
1 = Disabled
–
2 = Enabled
