Modems

The Cisco 1020 supports two types of modems, a PCMCIA Type-2 modem in the Async 2 slot, and an external modem connected to the Async 1 console port. The PCMCIA modems are listed alphabetically by manufacturer.

PCMCIA Modems

The PCMCIA modems in Table E-1 have been verified for use with the Cisco 1020.

External Modems

Most external modems will operate with the Cisco 1020.

Modem Tips

We recommend any reputable vendor of V.32bis and V.34 modems. For best results, the modem should be configured to:

• Lock DTE rate at 115.2k or as high as it can operate reliably

• Raise DCD when it senses carrier (usually &C1)

• Reset itself when DTR is dropped (usually &D3, sometimes &D2)

• Use hardware flow control (RTS/CTS)

• For use with dial-in, set S0=1 to answer the phone

Many V.Fast modems only seem to talk reliably when both modems are from the same vendor, and are not recommended. We recommend using V.32bis or V.34 modems with the Cisco 1020.
