Help: List the valid tv requests
Help returns a list of all of the valid requests used in MLT-2. Help can be
used when you are not sure which request to use in a particular situation, or
when you can't remember an exact request name. For example, the correct entry
to reverse polarity on a touch-tone line is "Rev.", help will tell you this.
For a description of any specific request, enter the name of the request
followed by a question mark.
Info: Get general information about a line
Info gives you the wire center name and the location of the frame; the
exchange key, MDF group and MDF trunk numbers associated with the subscriber's
line; the telephone number at the appropriate frame; and the assignment
telephone number. You can get information about a whole telephone number, an
NPA-NXX-, or an exchange key. MLT does not access the line when you request
info, but it keeps access if you already have it. If there are multiple
frames in an office, MLT give you information about all of them.
Keep: Keep an access that you already have
Keep lets you hold access to a no-test or MDF trunk that is about to
"timeout." MLT keeps track of which trunks you have accessed but have not
used for a while. MLT will automatically drop the access for you after a
certain period of time. About 2 minutes before dropping the access, MLT gives
you a warning message and also highlights the status line that will be
dropped. If you want to keep the access, you should enter "keep" in the req
field and the tn or line number of the access to be held. To drop an access
when your are finished with it, enter an x in the req field.
Lin: Test the inside part of the loop
Lin starts a series of tests on the inside portion of a line. Lin includes
the same tests as the loop test and can identify a co line circuit if one is
present. Lin does not do the regular line circuit and draw and break dial
tone tests. An MDF access is required for a lin request. You can use lin to
test special circuit that do not use co switching machine. For example, if
the circuit has 2 loops connected at the frame, lin lets you look at the
second loop (both full and loop only test toward one loop).
Lloop: Run the long loop analysis on the outside or loop part of a line
The ll request starts a series of tests which do extensive analysis of the
outside portion of the subscriber's line. It is specifically designed to
handle cases that the regular loop request was not designed to handle. These
cases include very long loops (over 100,000 feet) and multiparty lines on
moderate-to-very-long loops. It does similar measurements to those that loop
does, but analyzes the results differently. It expects to see a loop that has
no dc faults or only very light dc faults. If you use a loop on lloop on a
loop that has serious dc faults it will not do the long loop analysis.
Loc1: Measure distance to 1-sided resistive fault
Loc1 gets MLT to measure how far a one-sided fault is from the repair person,
because telephone lines can be very long, it can be difficult for a repair
person to find the location of a resistive fault. You can use loc1 to help
the repair person have 1-sided fault. You should be in contact with the
repair person on a line other than the one being measured. Have the repair
person open the pr at a ready-access point beyond the fault if possible. Ask
him/her to strap the pr tip to ring. Remember to enter a temperature on the
tv mask before you transmit the loc1 request.
Loc2: Measure distance to 2-sided resistive fault
Loc2 gets MLT to measure how far a two-sided fault is from the repair person.
Remember that you must run a locgp before you run a loc2 and that you must be
in contact with the repair-person on a line other than the one you will be
measuring. The repair-person must connect the bad pair to the good pair in a
specific way, the exact method to use is explained in the results of the locgp
request. Logcp and loc2 can also be used to sectionalize a one-sided
resistive fault. Remember to enter a temperature on the tv mask before you
transmit the loc2 request.
Look: Look for an intentional fault
Look is used to identify a fault, usually a short or ground, that has been
placed on the line by the repair person. Look can be used when a repair
person is having trouble locating a particular line. Look gets MLT to monitor
the line that the repair person is looking for. When the repair person shorts
or grounds the line, mlt sends a tone to you over your headset. You can tell
the repair person that you "see the short". A callback path is required for a
look request. You should talk to the repair person on a line other than the
one you are working on.
Lookin: Look for an intentional fault on a special services line
Lookin is used to identify a fault, usually a short or ground, that has been
placed on the special services line by the technician. Lookin is used to
locate a particular line by having MLT monitor the line that the repair person
is looking for. When the repair person shorts or grounds the line, MLT sends
a tone to you over your headset. You can tell the repair person that you "See
the short." A callback path is required for a lookin quest. You should talk
to the repair person on a line other than the one you are working on. MDF
access is required.
Loop: Test the outside part of the loop
Loop starts a series of tests that do an extensive analysis of the outside
portion of the line. Loop does every test that full does except the line
circuit and draw and break dial tone tests. Loop can be requested using
