If an SSC is not working, check that its CPA line jumper is set for
CPA to CPA, not CPA to CPB.
Motorola ASC (Advanced Simulcast Controller)
Figure 24: Interfacing to Motorola Advanced Simulcast Controller
* If the ASC has an internal modem option, you would not use the 202T, and would
cross-wire MODEM TIP to AUDIO TIP, and MODEM RING to AUDIO RING.
** At the time we tested with the ASC, it would not accept direct binary data input,
so required the external modem. We show both methods here.
Refer to the ASC Service Manual and Installation Guide for the P2 connector pinout.
Please note that the zoning (Sector Select on ASC) is an option on the ASC. The
parameter settings are the same as for the PSC/SSC/DDC on the previous page, but
parameter 06 (digital data polarity) may need to be inverted.
