FUNCTIONAL DESCRIPTION
L3000N- High Voltage Circuit
The L3000N line interface provides a battery fee-
dingfortelephonelinesandringinginjection.The IC
containsa statedecoderthatunderexternalcontrol
can force the following operationalmodes : stand-
by,conversationand ringing.
In addition Power down mode can be forced con-
nectingthe bias current resistor to V

The L3000Namplifies both the AC and DC signals
enteringat pin 6 (VIN) by a factorequal to 40.

L3030 - Control Unit
TheL3030lowvoltage controlunit controlsL3000N
line interface module, giving theproper information
to set line feed characteristic, to inject ringing and
TTXsignalandsynthetizesthelineand balanceim-
pedances.An on chip digital interface allows a mi-
croprocessor to control all the operations. L3030
definesworking statesof lineinterfaceandalso in-
forms the card controlleraboutline status.
L3000N - Working States
In order to carry out the different possible opera-
tions,the L3000Nhasseveral differentworking sta-
tes.Eachstateisdefinedbythevoltagerespectively
applied by pins 27 and 28 of L3030 to the pins 11
and 12 of L3000N.
Three differentvoltage levels (– 3, 0, + 3) are avai-
lableat each connection,so definingnine possible
