Using line diagnostics
MAX 3000 and MAX 6000 units that support E1 or T1 provide you with a set of diagnostic
command parameters, in the Line Diag menu, to test the performance of the units’ lines.
Initiate a line loopback test, swap the status of Non-Facility Associated Signaling (NFAS)
D-channels on applicable lines, clear each line’s user error event registers, and clear all
performance registers for each line using the options in the Line Diag menu.
A MAX 6000 unit that supports E1 or T1 lines has two slots, each of which supports two lines.
Each of the unit’s two Line Diag menus provide line loopback, clear event registers, and clear
all performance registers parameters for two lines, as in the following example of a MAX 6000
that supports T1:
10-000 Net/T1
10-200 Line Diag
>10-201 Line LB1
10-202 Line LB2
10-203 Switch D chan
10-204 Clr Err1
10-205 Clr Perf1
10-206 Clr Err2
10-207 Clr Perf2
A MAX 3000 unit that supports E1 or T1 lines has one slot that supports two lines. However,
the MAX 3000 unit can also include one drop-and-insert (North America integrated CSU) T1
line. The unit’s one Line Diag menu provides line loopback, clear event registers, and clear all
performance registers parameters for three lines, as in the following example of a MAX 3000
that supports E1:
10-000 Net/E1
10-200 Line Diag
>10-201 Line LB1
10-202 Line LB2
10-203 Line LB3
10-204 Switch D chan
10-205 Clr Err1
10-206 Clr Err2
10-207 Clr Err3
10-208 Clr Perf1
10-208 Clr Perf2
10-209 Clr Perf3
Clearing user error event and performance registers
The Clr Err1 command clears the user error event register of Line 1, the Clr Err2 command
clears the user error event register of Line 2, and the Clr Err3 command clears the user error
