@ 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.
5. Terminating the 2W connection is accomplished 6 ways.
A. Toggle the MODE SWITCH back to {A}.
B. 2W REMOTE PHONE is “hung-up”, by replacing the handset ON-HOOK,
or the circuit is interrupted by the Central Office (CO).
C. 2W REMOTE PHONE issues a 2 digit DTMF 2
nd
ALERT #, Our Example “58”
D. 4W Terminal issues a 2 digit SS4 command, Our Ex. “58”.
E. SERIAL program – “^” will perform warm boot.
F. Removing the power cord from the 524.
