Adapter
If you are installing one or more Analog Terminal Adapters (ATA), install
them after installing chassis cards.
To install an ATA:
1 Connect the analog telephone or fax machine to the analog port on the
ATA. The analog port on a 3C10120B ATA has a picture of an analog
telephone beside it. See
Figure 24 . The analog port on a 3C10400 or the
3C10400B ATA is labeled POTS (Plain Old Telephone Service). See
Figure 25 .
The Analog Terminal Adapter may require a telephone connector for use
outside North America. Contact your supplier for more information on
country-specific requirements.
2 Connect the Ethernet port on the ATA to the LAN. The Ethernet port on a
3C10120B ATA is the connector on the far left side. On the 3C10400B
