Physical description
CLASS Modem cards are housed in NT8D37 IPE modules.
The CLASS modem card circuitry is mounted on a 31.75 cm by 25.40 cm (12.5 in. by 10 in.)
double-sided printed circuit board. The card connects to the backplane through a 160-pin edge
connector.
The faceplate of the CLASS modem card is equipped with a red LED that lights when the card
is disabled. When the card is installed, the LED remains lit for two to five seconds as a self-
test runs. If the self-test completes successfully, the LED flashes three times and remains lit
until the card is configured and enabled in software, then the LED goes out. If the LED
continually flashes or remains weakly lit, replace the card.

Functional description
The CLASS Modem card is designed to plug into any one of the peripheral card slots of the
IPE module. The CLASS modem card supports up to 32 transmit-only modem resources, using
a DS30X interface. Up to 255 modems can be configured per system.
The CND transmission process begins with the CS 1000 software sending an initiating
message to the CLASS Modem card indicating the length of the CND information and the type
of the CND information flow to be transmitted. In response, the CLASS Modem card assigns
a message buffer to capture the CND information from the CS 1000 software.
System software then sends the CND information to the CLASS Modem card, one byte at a
time, where it is stored in the message buffer. If the CLASS Modem card receives more bytes
than were specified in the initiating message, then the additional bytes are discarded and not
included in the CND memory buffer.
