DSP ALARM & OVERVOLTAGE PROTECTION
DSP (Digital Services Protection) fully protects the phone against the
high voltages associated with many digital services. In addition the
phone is protected against connection to mains AC power circuits.
If an attempt is made to go off hook (TALK mode) on a circuit with a
potential of more than 115V ± 5Vdc the DSP alarm will sound (a con-
tinuous buzzing tone is emitted). The line is not looped and the inter-
nal circuitry is protected.
If the phone is accidentally connected to AC mains in MONITOR
mode (on-hook) the phone will ring continuously.
If in TALK mode the line will not be looped and the DSP alarm will be
emitted.
In either case disconnect immediately !
