Error Counters
These error counters give a second-by-second snapshot of the
link performance. To clear all counters, press the [Backspace] key. If
your keyboard does not have this key, you can press a two-key combi-
nation to affect the same result: Hold down the [Ctrl] key and then
press the [H] key. This will send to the unit the Ctrl-H character, which
is the same as pressing the [Backspace] key.
Rx PRM
The NetLink-T1™ transmits ANSI performance report messages
once a second when the framing mode is ESF. When the ESF Data
Link is set to ANSI T1.403, the unit recognizes PRMs with addresses
of 38h or 3Ah. The address 3Ah indicates the PRM is coming from a
Carrier, whereas the address 38h indicates the PRM is coming from a
Customer. When the ESF Data Link is set to AT&T TR54016, the unit
recognizes Carrier-originated PRMs, which have an address of 3Ah.
Current DIP Switch Settings
The Switch settings are displayed here to
facilitate troubleshooting your unit without
opening up the unit first.
3.3.6 Unit Information
The Unit Options screen looks like this (factory default):
Header Line 1 & Header Line 2
Headers 1 and 2 are provided for easy identification of your unit
after installation. You may want to give each unit a unique name via
the header lines to help distinguish one unit from another. You can
enter a header up to 40 letters long. Two lines provide 80 letters for
your use. That’s a lot of flexibility!
Password
The Password facility provides security by allowing only those who
know the correct password to configure the unit via the control port. You
can still configure the unit via the DIP switches. The password can be up
to 16 characters long, with no restriction on the combination of charac-
ters you can use, so be sure to remember the password. If you lose your
password, you will lose the ability to access the unit via the control port.
Loop Timeout
The Loop Timeout setting can be set to one of the following:
00:05 =
five minutes
00:10 =
ten minutes
00:15 =
fifteen minutes
00:30 =
thirty minutes (default setting)
00:45 =
forty-five minutes
01:00 =
one hour
01:30 =
90 minutes
02:00 =
two hours
03:00 =
three hours
NEVER =
forever—the unit will remain in loopback without user
intervention.
