NT6D71 UILC line card
Page 421 of 544
Option 11C and 11C Mini
Technical Reference Guide
The CardLAN interface is used for routine card maintenance, which includes
polling the line cards to find in which card slot the UILC is installed. It also
queries the status and identification of the card, and reports the configuration
data and firmware version of the card.
The IPE bus interface connects one IPE bus loop that has 32 channels
operating at 64 kbps and one additional validation and signaling bit.
The Maintenance Signaling Channel (MSC) interface is used to communicate
signaling and card identification information from the Meridian 1 CPU to the
UILC MCU. The signaling information also contains maintenance
instructions.
The digital pad provides gain or attenuation values to condition the level of
the digitized transmission signal according to the network loss plan. This sets
transmission levels for the B-channel circuit-switched voice calls.
The clock converter converts the 5.12 MHz clock from the IPE backplane into
a 2.56 MHz clock to time the IPE bus channels and an 8 kHz clock to provide
PCM framing bits.
U interface logic
The U interface logic consists of a transceiver circuit. It provides loop
termination and high voltage protection to eliminate the external hazards on
the DSL. The U interface supports circuit-switched voice and data terminals,
D-channel packet data terminals, and NT1s. A UILC has eight transceivers to
support eight DSLs for point-to-point operation.
Physical description
The NT6D71 UILC is a standard size circuit card designed to be inserted in
peripheral equipment slots in the Meridian 1. Its faceplate is equipped with an
LED to indicate its status.
Power consumption
Power consumption is +5V at 1900 mA.
