Power requirements

Table 85: LEI card - power required
that the LEI requires from the backplane. One NT8D06 IPE Power Supply AC or NT6D40 IPE
Supply DC can supply power to a maximum of eight LEIs.

Foreign and surge voltage protections

In-circuit protection against power line crosses or lightning strikes is not provided on the LEI.
It does, however, protect against accidental shorts to –52 V dc analog lines.
When the card is used to service off-premise terminal equipment through the public telephone
network, install a Line Termination Unit (LTU) as part of the terminal equipment to provide
external line protection.
