5.11 Remote Configuration

In remote configuration mode, any valid AT command which does not drop the line can be

issued (but without the AT prefix) to reconfigure a remote modem. Typically the command

is left disabled and is temporarily enabled at the remote site by entering the escape

sequence ('pause'

+++

'pause') then AT*R1 if on-line, or simply AT*R1 if off-line.

Holding down the LOOP button at the instant power is applied will also temporarily enable

remote configuration.

The central site can then call in and examine S-registers with the AT*C command or

reconfigure the DPX-213. The central site should execute AT*R0 before it hangs up or the

remote modem should be turned off and back on again to disable the remote configuration

option. Password protection (AT*P) is recommended to guard against malicious

reconfiguration.
