3.5.4 Serial Interface Remote Communication via Modem
This section describes the procedure for establishing a remote dial-up connection to the
ONS 15216 EDFA2. ONS 15216 EDFA2 remote communication requires two US Robotics 56K Fax
modems set up to send data over a two-wire dial-up telephone line. (See
Figure 3-7
.)
This section assumes the use of the US Robotics 56K Fax modem V.90. Other modem types may require
different settings to establish a remote dial-up connection. The user should review their modem
documentation to ensure compatibility between US Robotics and other vendor modem types.
