7.4 Ring Over Page
When a customer-provided paging system is installed (refer to section 7.2), incoming calls can be
assigned to Ring Over Page (ROP). By means of the relevant program (MMC), program a line or
lines to ring a hunt group and assign ROP as a destination in this hunt group. ROP can be used
for day or night operation or both. Refer to the DCS-816 Programming Manual.
7.5 Station Message Detail Recording (SMDR) (Figure 7-4)
To receive an SMDR printout, connect a customer-provided printer to one of the serial interface
connectors (DB9) on an SIO option card (Figures 3-1 and 3-2). Before connecting the printer or
the call accounting device, ensure that the system power is turned OFF. Any external battery, if
installed, should also be removed. Otherwise, the system as well as the external device may be
severely damaged.
Use a pin-to-pin RS232C cable. Only pins 2, 3, 5 and 6 are required. When the printer or optional
call accounting device needs to be more than 5 metres away from the system, shielded computer
cable is required. Connect a male DB9 connector to the SIO card and then connect a connector
that meets the requirement of the printer or the call accounting device to the other end. The cable
must not exceed 100 metres.
