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 |
