@ MODEL 524 SMART AUDIO BRIDGE
1.
MODE SWITCH toggled from {A} TO {C} will connect the
524
to the 2W 224 REMOTE
INTERFACE OR THE CO (Central Office). The 4Wire circuit doesn
’t hear any of the 2wire
audio (DTMF signaling, dial tones, and busy signals.) until step 4.
2.
The
524
dials the stored telephone number saved in programing step (D# 15n #). If the line is
busy or if the operator wishes to terminate the call, toggle the MODE switch back to {A}.
3.
Once the 2W Remote Phone operator knows that the
524
is trying to connect, HE or SHE
MUST enter the BRIDGE PASSKEY (reference programming step DB1xxxx) within 30
seconds or the
524
will automatically terminate the call. BRIDGE PASSKEY is set as
“79” for
the DEMO.
4.
Once the 2W Remote
Phone has “picked-up”, entered the PASSKEY # “79”, the
524
will
change the front LED to GREEN, deliver a HI/LO confirmation tone to both the 2W circuit and
the 4W circuit, signifying that a [2W-4W BRIDGE] condition is enabled.
