CO Interface Boards
The types of CO Interface boards are listed in the table and narrative that follow.
Direct Inward Dial Board
The Direct Inward Dial Board (DIDB) provides four analog DID CO interface ports. The DIDB can
be optionally equipped with a DTMF Receiver Unit (DTRU) to detect DTMF tones. If a DIDB is
used, a DTRU is required; it does not necessarily have to be mounted on the DIDB, but it must
be installed within the system.

Add-on Boards: DTRU
Loop Start CO Line Interface Board
The Loop Start CO Line Interface Board (LCOBC) provides Loop Start CO Lines which support
pulse/DTMF signal. Each interface contains ring and loop current detection circuits, Analog-to-
Digital and Digital-to-Analog conversions, and pulse and ground flash signaling circuits. The
LCOBC contains LEDs to indicate the in use status of each CO Line.
The LCOBC is Caller ID capable and has an RJ21-type male connector.
The LCOBC can be equipped with a DTMF receiver unit (DTRU4) to detect DTMF tones.

Add-on Boards: DTRU4 and CIDU
Voice Over the Internet Protocol Cards
The Voice Over the Internet Protocol (VoIP) card provides up to eight lines per card (two lines
per installed VOIP module). The VoIP24 card provides up to 24 line per card when a
daughterbaord is used. The VoIP/VoIP24 card allows bi-directional voice communication to
other devices via an IP network such as an internal Local Area Network (LAN), the Internet, or
a Wide Area Network (WAN) using the Ethernet Interface. It monitors for disconnect while using
minimal bandwidth. It also provides four-digit dialing and other features. The VoIP card uses up
to 8 fixed time slots and programming allows the use of up to 16 additional time slots that can
be used for either stations or CO lines.
