CME paging integration with TOA – 900 Series II A-912MK2

[peterson.m]

My client's implementing a CME solution and needs to integrate their legacy paging using an FXS port. They have a TOA A-912MK2 paging amplifier. Documentation says telephone paging would connect to a TOA B-41S balanced line input module on the 900 series amp. Is a TAMB module required and would it work for this integration? Anyone integrate Cisco voice with a TOA 900 series before?

Here are the specs for the B-41S module -

B-41S
Balanced Line with Input with Mute-Send

For balanced or unbalanced, line level equipment such as AM/FM tuners, tape decks and CD players. Transformer isolation minimizes ground loop problems when connecting remote equipment. Signal at input terminals activates mute bus.

• Controls/Functions:
  
  • Mute Send Sensitivity
    
• Performance Input: 10 kohms
  
• Input Sensitivity: -16 ~ -34 dBu
  
• Gain (Adjustable): -2 dB
  
• Physical Connector:Removable Terminal Block
  

Thanks

Hi there,

You are most correct

If you look on Page 15 of the doc you attached, the TOA-900

is looking for a Paging output from the telephone system and not

a FXS/FXO/E&M connection. So you will  "mid-point"  integration piece like the TAMB-2 (see link)

or older TAMB between the FXS/FXO and TOA-900. The TAMB will answer the call

and then bridge across the audio to the paging system.
