Description

The GCD-4COT( ) blade provides:
GCD-4COT( ): Four analog loop start/ground start trunk circuits

One trunk status LED

One Blade status LED

Four Caller ID Circuits

Two Power Failure Transfer Circuits

Connection for GPZ-COT( ) Daughter Board

The GCD-4COT( ) blade consumes four trunk ports ranging between ports
001~400. The CN2 connector provides connection to four analog trunk
ports, which are polarity sensitive (tip-to-tip, ring-to-ring). The power
failure circuits (CN3), however, are not polarity sensitive.

Installation

Install the GCD-4COT( ) blade into an available slot in the chassis. (Refer to
Figure 4-19 GCD-4COT( ) Blade on page 4-51
 If the GPZ-COT( ) is to be used, install this prior to inserting the GCD-
4COT( ) blade into the chassis.
When using the GCD-4COT( ) blade for ground start trunks,
the PBX ground must be connected as described in Chapter 3,
section 3.3.3 Install Grounding on 19" Chassis on page 3-19
for the trunks to function correctly.
The trunk ports are polarity sensitive. Be careful when wiring
the trunks.
When connecting the RJ-61 cables to the GCD-4COT( )
blades, note the position of the Power Failure connector
(CN3). Do not confuse this connector as the trunk connector
(CN2).
Switching from Loop Start to Ground Start is set in system
programming.
Do not wire an RJ-11 directly to the GCD-4COT( ) interface.
Use the appropriate RJ-61 wiring when connecting to the
GCD-4COT( ).
