Q.1 My phone bills are too high.
Ans. This is one of the most common complaints from our subscribers. Here are a few tips to
keep your bills low.
If you have STD facility :
Use dynamic locking when not making STD calls. Also remember that 900 (premium
service calls) are charged like STD calls.
If you do not have STD facility :
You can still use dynamic locking to bar outgoing calls. You have to ask for dynamic locking
facility from your DE(Internal). Also remember that 95 calls (upto 200 km), are also
available to subscribers without STD facility. These calls are charged at higher rates than
local call. You can bar these calls in the same way as told above. Q.2 My friend says his phone is faulty, but when I ring his phone no. I get ring back tone .
Why so? Ans. Listening to ring back tone is not the same as ringing of the destination phone. In the
present design of phone system if there is no short circuit fault on a phone line, and
someone rings that phone he/she gets to hear the ring back tone. If the phone line is OK,
and a phone instrument is connected on the destination phone line the phone rings also.
So, you will hear ring back tone if the cable pair / wire to the target phone is torn for some
reason.Again, if there is short circuit fault on the phone line, the short circuited line starts
draining current from the Exchange. To prevent this undesirable current drain, at the
Exchange Main Distribution Frame (MDF) the affected cable pair is isolated / disconnected
by means of a plastic strip. This is called “wedging” of phone line. As you can see,
wedging converts the short circuit fault into a physical disconnection / isolation of the phone
line cable pair. So, anyone ringing a “wedged” phone no. will get to hear ring back tone.
These are the two ways you hear ring back tone even on dialing a faulty phone line. |
