Personal experience a few years ago trying to transmit in a
low frequency restricted band for a product into Europe...
Doesn't matter even if it is too small a signal to be
measured, thou shalt not transmit in that band.
Yet, spurious signals up to a certain level is always
allowed, go figure.
Hail EMC gurus!
15.205 prohibits most non-spurious transmissions in restricted bands.
"(a) Except as shown in paragraph (d) of this section, only spurious emissions
are permitted in any of the frequency bands listed below:..."
Is there some level of transmission at which non-spurious transmiss

This is going back a few years, and I'm no longer in telecom, but here's

I know Deutsche Telekom had CO's with the higher voltages - maybe BT

The battery voltage you mention at other than nominal -48 Vdc has often
been referred to as "German battery." This CO battery voltage operates
at a nominal -60 Vdc and is supposedly only present in telecommunication
networks in a small region in parts of Germany and Austria.
Since your f

Anyone out there possibly suggest a manufacturer source for a 8 conductor 16

of Steward part.

Dear Members,
An English version of a draft copy of the above-referenced standard is
available at http://www.graspllc.com/China%20RoHS%20Standards%20-%20Limits.php

The Chinese version of this standard was attached to the second meeting
minutes of the China RoHS working group dated April 25, 2
If the battery voltage is in line with ETSI Standard EN 300 132-2 that define
the power interface in a telecom installation the voltage is in the range
-40.5 to -57V and is considered SELV. See also the IEC TR 62102.

Dear Jeff,
The WPC notification states "type approved" not "type certification". Type
