TLU80 - E&M interface to voice recorder

[kkong42]

Hi,

I have a new MX-ONE system with a TLU80 card, which I'd like to interface to an external voice recorder by means of E&M signalling.

Is it the TL22 function block that I'd need to use? Any idea what VARC and VARO parameters would be for the RODAI command?

The recorder is operating in 4-wire mode (it sends beeps back to the caller, records the message and then broadcasts it over a public address system) and is looking for an earth on the M-lead to indicate that it should start recording.

I guess I would also like confirmation of the SIG parameters for the ROCAI command.

Thanks for any help anyone can offer.

Hi

This is what I have tried as E&M 4 wires in BC9
[tt]
ROCAI : ROU = X , SEL = 711000000000 , TRM = 7 , SERV = 3110000000 , NODG = 0 , DIST = 30 , DISL = 128 , TRAF = 03151515 , SIG = 111100000000 , BCAP = 001100 ;
RODAI : ROU = X , TYPE = TL22 , VARC = 031F1032 , VARI = 00012040 , VARO = 04211010
RODDI : DEST = Y , ROU = X , ADC = 0005000000000250 , SRT = Z ;
ROEQI : ROU = X , TRU = 1 - 1 , EQU = 1 - 0 - 32 - 0 ;

Best regards
