Configuration Tasks for Lines
Changing Map Tables
You change map table entries one at a time. A change removes an existing mapping and replaces it with
a map between the old source and new destination. To apply a change, the following must be true:
• The command must specify an existing map pair.
• The new destination must be unassigned.
Changing a map entry interrupts service to a large number of subscribers. Perform this task on inactive
lines or during light traffic periods.
To change an existing map entry, enter the chm13 command. For example the following command
sequence adds three map table entries and then changes one of them:
addm13 1 3 1 1 3
chm13 1 3 1 4
The example creates the following map table:
Deleting Map Table Entries
You can delete map table entries individually or in a range. When deleting a range of entries, the entire
number of source and destination lines should be contiguous. The system stops deleting lines if it
encounters a break in source range, deleting only those lines before the break.
Deleting map entries discontinues or interrupts service to a large number of subscribers. Perform this
task only on lines that are out of service.
To delete map table entries, enter the delm13 command. The following example deletes three sequential
map table entries, starting at DS3 line 1, DS1 line 1:
delm13 1 1 3
Viewing Map Tables
You can view the map table for the system as a whole or for individual source DS1 lines.
To view map tables for a single source DS1, enter the lsm13 command, specifying the number of the
source DS3 line and number of the DS1 line within the DS3 line. Valid entries are 1 through 6 for the
DS3 and 1 through 28 for the DS1.The system lists map table entries for the specified line.
