7.1 Analog Voice I/O Card Components
User-relevant components on the Analog Voice I/O Card include:
• edge connector
• port connector
• Line Interface Driver (LID)
The edge connector fixes the card to any one of the motherboard’s expansion slots
1-8.
The connector plate fixes the female six-wire RJ-12 and the female eight-wire PB-
45 connectors to the chassis rear panel with two Phillips-head screws.
NOTE:
Attachment of the connector plate to the chassis is required at all times for
good grounding.
The LID is a daughterboard which mounts on the Analog Voice I/O card and
controls the voice channel signalling and network line interface. The LIDs ar
further described in paragraph 7.3.
NOTE:
The PB-45 connector is mechanically identical to an RJ-45 connector, but
the PB-45 connector is used in equipment-to-equipment connections rather
than equipment-to-network connections.
