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.
