iDCS 100 INSTALLATION
TECHNICAL MANUAL PART 7 JUNE 2002
7.3
Use a pin to pin RS232C cable. Only pins 2, 3, 5 and 7 are required (see Figure 7–7).
When the printer or optional call accounting device needs to be more than 15 feet away
from the KSU, use shielded computer cable. Attach a male DB9 connector to the
SMISC end and then attach one that matches the requirements of the call accounting
device or printer to the other end. This cable must not exceed 300 feet.
Use MMC 725 to set SMDR print options and MMC 804 to set the transmission
parameters and the SMISC port.
7.6 PC PROGRAMMING
To program the system via a personal computer (PC), connect a PC equipped with
PCMMC to a serial interface connector on the SMISC card (see Figure 7–6). SI/O 1
defaults as PCMMC.
Use an RS232C cable with connections as shown in Figure 7–8. When the PC needs to
be more than 15 feet away from the KSU, use shielded computer cable. Attach a male
DB9 connector to the SMISC end and then attach one that matches the requirements
of the PC to the other end. This cable must not exceed 300 feet.
Use MMC 804 to set the transmission parameters and the SMISC port.
7.7 REMOTE PROGRAMMING
To remotely program a system, connect a customer-provided modem to a serial
interface connector on the SMISC card (see Figure 7–6).
Use an RS232C cable as shown in Figure 7–9. When the modem needs to be more
than 15 feet away from the KSU, use shielded computer cable. Attach a male DB9
connector to the SMISC end and then attach one that matches the requirements of the
modem to the other end. This cable must not exceed 300 feet.
Use MMC 804 to set the transmission parameters and the SMISC port to be used.
7.8 POWER FAILURE TRANSFER (PFT)
When the system loses AC power, the first two loop start lines of each S3TRK card are
automatically switched to the PFT pairs on the connecting block (see Figure 7–10).
Cross-connect these outputs as shown in Figure 7–10 to the TIP and RING pairs of the
single line phones that are to have power failure operation.
7.9 VOICE MAIL/AUTO ATTENDANT
System operation provides special programming and hardware for use with a
customer-provided voice mail/auto attendant system. The single line stations on the 2
SLI card, S8SLI card and the 2 X 4 SLI card can provide a disconnect signal required
