When any page ac-cess code is dialed, a ground output is appliedto the PGl lead to mute the music.9.36 All paging connections are made at the J2 andJ502 or Jl and 52 connectors on thePERCEPTION,&,, systems, respectively. Theconnectors are located on the rear of the basic andexpansion cabinets. See Tables 5-4 and 5-10 fordetails,9.40 Music-on-Hold9.41 A Music-on-Hold (MOH) interface is a stan-dard feature on the system. The circuitry occupiespart of the NPRU PCB. If MOH is equipped, it will beheard by any station or trunks on-hold in the sys-tem, or by any trunk put into the camp-on state.9.42 A tuner or other program source, supplied bythe customer, is connected to the MOH input via pins4 and 29 (Br-W and W-BR) of J2 or J502 / Jl or J2forthe PERCEPTIONe&exsystems, respectively(seeTables 5-4 and 5-10). The input impedance is 600ohms. (This cannot be the same source used toprovide music over external speakers.)9.43 Adjust the MOH volume with the MOH vol-ume control on the front of the NPRU PCB. Maxi-mum volume is limited by internal circuits in orderto comply with FCC regulations.9.50 Universal Night Answer9.51 The Universal Night Answer (UNA) featureprovides an output of interrupted ringing voltage(85 +10 VRMS, 20 Hz superimposed on -24 VDC)whenever the system is in Night Service and anincoming call is received by a trunk designated forUNA. Any station user, upon hearing the chime orbell, can dial the UNA access code and be con-nected to the caller.9.52 The ringing voltage output is intended tocontrol a strategically located chime or loud ring-ing bell. The available power is five ringer equiva-lents.9.53 Two UNA zones can be installed in tenantsystems. Either zone can be assigned in program-ming to either tenant. For PERCEPTION,, con-nections to the UNA ringing signal are via pins 12and 37 (0-BK, BK-0) of J2. This connection is toJ502 in the expansion cabinet for UNAZone 1 (seeTables 5-4 and 5-10). UNA zone 1 requires asecond NPRU PCB in the expansion cabinet.4-62 |
