CO/PBX Connections

CO/PBX Connections
The two types of analog CO/PBX Line interface boards available are the Loop Start CO Line
Interface Board (LCOBC) and the Direct Inward Dial Interface Board (DIDB).
There are five types of digital CO/PBX Line Interface Boards available. These boards include
the T1IB, PRIB, BRIB, VOIP, and VOIP24 card.
When using CO Lines as additional music inputs, keep in mind that the music source may
require a talk battery in series with either TIP or Ring. This talk battery boosts the signal level
sufficiently so that the CO Line interface can read the signal.

Analog CO/PBX Line Interface Boards

Loop Start CO Interface Board
The Loop Start CO Interface Board (LCOBC) supports up to eight (8) Loop Start CO Lines, is
Caller ID capable, and can be optionally equipped with a DTMF Receiver Unit. The LCOBC can
be optionally equipped with a Caller ID Unit (CIDU).
Each Interface contains ring and loop current detection circuits, Analog-to-Digital and
Digital-to-Analog conversions, and pulse and ground flash signaling circuit. The LCOBC
contains LEDs that illuminate to indicate the in-use status of each CO line. The RJ21 type male
connector is mounted on the front edge of the LCOBC for connecting to the CO lines.

Add-on Boards: DTRU4 and CIDU
Installing the DTRU4 Module
DTRU4 to LCOBC
1. Unpack the DTRU4 module from its antistatic conductive bag.
2. Locate the CN1 and CN2 connectors on the DTRU4 module.
3. Locate the CN2 and CN3 connectors on the LCOBC.
4. Position the DTRU4 module so that the CN1 and CN2 connectors align with the CN2 and
CN3 connectors on the LCOBC respectively.
5. Push the DTRU4 onto these connectors to seat it securely.
