Re: Worldwide weekend of free WiFi with Skype Access [telecom]
Amongst my clients and acquaintances who have contacts in other

Some tariffs are a requirement of the regulator but some tariffs are
initiated and filed by the carrier, then approved by the regulator.
For example, so far as I know, most calling features are (were in the
case of California) offered under LEC-initiated tariffs.

Typical parking lights are rated 8-15 Watts, hence take an Ampere or so,
plus or minus 30%, and a set of four will drain about 4 Amps. Over 6 hours,
that'd be roughly 25 AH, which is "nothing" to a 300 AH-rated battery.
Right: a headlamp's low beam filament will consume about 7 A (or at

Re: Mississippi makes Caller ID spoofing illegal [Telecom]
My understanding is that the LEC expects the PBX to supply the CID
because of the class of trunk that is provisioned for the PBX. Thus,
the LEC is a party to any spoofing.

I don't think that's a valid analogy: after all, the LEC expects

Yes, a car battery will work fine as a backup power source. Once.
A deep discharge will permanently damge the battery. You can recharge
it, but its capacity is now permanently reduced. Do it again, and you
further damage it and further reduce the capacity.
