## External Modems

  Most external modems operate with the PortMaster Office Router.

## Modem Tips

  Lucent recommends any reputable vendor of V.32bis or V.34 modems. For best results, configure the modem to do the following:
  - Lock the data terminal equipment (DTE) rate at 115.2Kbps or as high as the modem can operate reliably
  - Raise DCD when a call comes in
  - Reset itself when DTR is dropped
  - Use hardware flow control (RTS/CTS)
  - Answer the telephone on the first ring for dial-in use
