5.1.1 Description
The GCD-4COTB blade provides:
GCD-4COTB: 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-4COTF Daughter Board
The GCD-4COTB 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.
Refer to the following tables for maximum upgrade capacities of the
GCD-4COTB blade:
Table 2-6 SV9100 Maximum 9.5” Gateway and 19” System
Capacities – Blades on page 2-12
Table 2-7 SV9100 Maximum 9.5” Base and Expansion System
Capacities – Blades on page 2-14
5.1.2 Installation
Install the GCD-4COTB blade into an available slot in the chassis. (Refer to
Figure 4-21 GCD-4COTB Blade on page 4-58 for a layout of the blade.)
If the GPZ-4COTF is to be used, install this prior to inserting the
GCD-4COTB blade into the chassis.
❍ When using the GCD-4COTB 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-4COTB 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-4COTB interface.
Use the appropriate RJ-61 wiring when connecting to the
GCD-4COTB.
