Rev helps you identify a touch-tone polarity reversal. On a good line, the
battery is connected to the ring wire and the ground is on the tip wire.
These wires must be connected to specific terminals on the telephone. If they
are reversed, the subscriber will be able to receive calls but will not be
able to dial out. If the line is reversed, you won't be able to hear the
tones before you enter a rev request. Rev only reserves the line temporarily.
A callback path should be established before you make a rev request.
Rin: Ring a subscriber's special services line
Rin lets you ring a telephone on a special services line. A callback is
required. If one doesn't exist, ring in sets one up for you. To answer the
callback, answer its ring and press "0" on the touch-tone pad, and listen for
ringing. When the subscriber answers, you will be placed in talk mode. If
the line is busy, the call in progress will be interrupted. Use rin to
contact the subscriber or a technician at the subscriber's home. MDF access
is required to request rin.
Ring(#): Ring a specific party on a multi-party line
Ring(#) lets you choose the telephone that you want to ring on a multiparty
line. A multiparty line is one on which more than one subscriber is connected
to the same pair of wires. Normally MLT checks the line records of the
telephone number you enter using the ring request, and automatically rings the
correct party. When the line records indicate 2, 4, or 8 party, use the
ring(#) request and specify the party number in place of the "#." If you
request ring1, MLT rings the party connected to the ring side. If you request
ring2, MLT rings the party connected on the tip side.
Ring: Ring a subscriber's line
Ring lets you ring a telephone on a single party line. A callback path is
required but if one doesn't exist, ring sets one up for you. To answer your
callback, answer its ring and press "0" on the touch-tone pad, and listen for
ringing. When the subscriber answers, you will be placed in talk mode. If
the line is busy or cannot be rung, you will be placed in monitor mode to
listen for noise or speech. Use ring to contact the subscriber or a repair
person at the subscriber's home.
Ringer: Check ringer configuration on a line
Ringer counts the number of ringers on each part of the loop (tip-ring,
tip-ground, and ring-ground). The results tell you the number of telephones
found by MLT. If there is a problem, the summary explains the problem. If
you are testing a party line, some of the ringers found may belong to the
other party.
Rin: Ring a subscriber's special services line
Rin lets you ring a telephone on a special services line. A callback is
required. If one doesn't exist, ring-in sets one up for you. To answer the
callback, answer its ring and press "0" on the touch-tone pad, and listen for
ringing. When the subscriber answers, you will be placed in talk mode. If
the line is busy the call in progress will be interrupted. Listen for noise
of speech. Use rin to contact the subscriber or a technician at the
subscriber's home. MDS is required to request rin.
Soak: Identify swinging resistance condition
Soak identifies unstable ground faults (swinging resistance) on a line.
Voltage is applied to the line and a series of DC resistance measurements are
made to see the effect of that voltage. If the resistance values are all low,
the fault is probably stable. If even one value is 20% larger than the
original measurement, the fault may be unstable (swinging). A repair person
who is dispatched may have trouble locating a swinging fault. Use soak when
you find a 10-1000 kohm ground on a q test (full & loop include the soak
test), or just prior to dispatch to double-check a line's condition.
Ssa: Special services access
The ssa request is used to access non-locally switched customer telephone
lines. Accessing these lines is a special case of a no-test trunk access.
However, if they go through a digital loop carrier such as SLC Series 5, and
there is special equipment available in the co, then you can test them with a
no-test trunk special se rvices access. This means you don't have to call the
trunk. The request can only be run from the stv mask.
Stv: Special services trouble verification request
The stv request changes you from a tv mask to an stv mask. Stv is used when
you need to test special services circuits (non-locally switched lines) served
by digital loop carrier systems such as SLC Series 5. Switching to the stv
mask will not affect any information you left in the tv mask -- your status
lines will remain the same; however, the middle section of the mask will be
changed. Any request done from a tv mask can also be done from an stv mask,
but not vice versa. The stv request can only be run from a tv mask.
Take: Take control of a long-term access
Take is used when you want to transfer a long-term access from someone else's
terminal to your terminal. To take control of a no-test access, enter the
telephone number that you want to transfer in the tn field. To transfer an
MDF access to your terminal, enter the NPA-NXX in the tn field and the MDF
number in the space to the right of the regular tn field of the tv mask.
Finally, enter take in the req field. If the previous holder had a callback
established, it would not be remover. If necessary, you must remove the
callback using xcb and request a new callback to your telephone.
Talk: Talk over the subscriber's line
