DHS Installation 2-45
10. Connecting and Programming Caller ID
The purpose of this service is to provide calling party identification to the dialed party.
This information can be the calling party’s phone number, name, or a combination of this
information. The information is delivered in between the first and second ring. The
system can use this information to: Provide LCD information to stations receiving calls,
maintain a list of unanswered calls for call back via the caller ID information.
When Incoming Caller ID is to be used with the DHS it is necessary to use the caller ID
box. The caller ID box must be connected to the DHS system ICLID/PC Programming port
using the Caller ID Cable. The caller ID box collects data at each CO line to be used for
Incoming Caller ID and passes the data to the DHS system for processing. Each DHS CO
line port must be programmed for the associated caller ID box port in customer database
programming.
The caller ID box module is connected to the DHS system via the ICLID/PC programming
port on the Option Module. Consequently, the PC programming port cannot then be
used for PC-based programming and Incoming Caller ID data collection simultaneously.
When all hardware connections are complete, adjust the caller ID box option switches for
1200 BPS operation. Program the DHS system PC Programming port for 1200 BPS
operation. A proprietary cable can be ordered (refer to Table 2-5 ), or you can use a
standard null modem.
