Chapter 2 Preparing AXSM Lines for Communication
General AXSM Provisioning Procedures
Channelizing a SONET Line
When a SONET line is in clear channel mode, it carries a single STS-3 path.
To channelize a SONET line into three STS-1 paths, perform the following steps.
Step 1 Establish a configuration session using a user name with GROUP1_GP privileges or higher.
Step 2 Enter the cc command to change to the card you want to configure.
Step 3 If you have not done so already, bring up the line to be configured as described in the “Bringing Up
Lines” section, which appears earlier in this chapter.
Step 4 Enter the dsppaths -all command to see the path ID numbers for all STS-1 paths on the current card,
and obtain the path ID for the path you want to channelize.
M8950_DC.16.AXSMXG.a > dsppaths -all
path Admin path path path Oper
path Type Status Payload Width Alarm State
----------- ------- -------- --------- -------- ------- ----------
1.1.1 sts Down unequipped 48 Unknown Down
Shelf Database table empty.Ds3PathsTable
Step 5 Enter the cnfpath -sts <path_id> -width 1 command to set the path width. Although this command has
many options, you must channelize the line before you bring up and configure individual paths. The
command form that channelizes the line is as follows:
cnfpath -sts < path_id> -width 1
Replace the path_id variable with the complete path number in the format bay.line.sts, as shown in
Table 2-9.
Step 6 Enter the dsppaths -sts command to verify that the line has been channelized into three separate STS
paths, as shown in the following example.
M8950_DC.16.AXSMXG.a > dsppaths -sts
path Admin path path path Oper
path Type Status Payload Width Alarm State
----------- ------- -------- --------- -------- ------- ----------
1.1.1 sts Down unequipped 12 Unknown Down
1.1.13 sts Down unequipped 12 Unknown Down
1.1.25 sts Down unequipped 12 Unknown Down
1.1.37 sts Down unequipped 12 Unknown Down

Note The software supports only the path widths described in Table 2-9. When you create a path by dividing
a larger path or combining smaller paths, the software may automatically create additional paths to
assure that all the available bandwidth is assigned to one of the available path sizes.
