170.2 EQUIPMENT DESCRIPTION
1. ESE-32B-1 CCU
This CCU is the basic Central Control Unit. This steel
cabinet is designed to accommodate other expansion
CCUs. A PSE-AD-1 or PSE-DD-1 power supply is
required to provide service. It also requires a
CPU-E(or higher revision) ETU and a TSW-E( ) ETU.
The ESE-32B-1 CCU provides eight slots in the
interface card section that can support four ports each.
The ETUs that can be installed in these eight slots are:
COI-E, COI-EB,TLI-E, TLI-EB, ESI-EA, ESI-EB, SLI-
EA, SLI-EB, CNF-E, MFR-EA, ECR-E and VMI-E
ETUs.
installed. The first expansion CCU expands the total
system capacity to sixty-four ports. Two expansion
CCUs provide service for system capacity of ninety six
ports. The third expansion CCU allows the system a
maximum of 128 ports.
3. CCU BASE WALL MOUNTING PANEL
This unit is required for wall mounting the third
expansion CCU (ESE-32E-1).
Additionally, there are three slots in the common
control/optional card section. Two of these three slots
are occupied by the CPU-E( ) and the TSW-E ETUs.
One slot can be used to install an optional common
card such as an SMDR-E or an LCR-E ETU.
When slot eight in the interface card section is not
occupied, it can be used to install another optional
common card.
The ESE-32B-1 CCU (maximum one per system)
provides service for up to thirty two ports.
2. ESE-32E-1 CCU
This CCU is the expansion Central Control Unit. This
steel cabinet is designed to be stacked on top of the
ESE-32B-1 CCU or on top of another ESE-32E-1 CCU;
it is not a stand alone unit and must be used in
conjunction with the ESE-32B-1 CCU.
The ESE-32E-1 CCUs require a PSE-AD-1 or
PSE-DD-1 power supply to provide service to all
equipment supported by this CCU. It also requires an
MMC-E ETU to control this equipment.
The ESE-32E-1 CCU provides eight slots in the
interface card section; each section can support four
ports. The ETUs that can be installed in these eight
slots are: COI-E, COI-EB, TLI-E, TLI-EB, MFR-EA,
ESI-EA, ESI-EB, SLI-EA, SLI-EB, CNF-E, ECR-E,
and VMI-E ETUs.

4. PSE-AD- 1 PSU
The PSE-AD-1 PSU is an AC/DC power supply and
when used, is mounted in each CCU. This PSU
converts nominal 117 VAC into the necessary voltages
required to operate the system.
In addition, there are three slots in the common
control/optional common card section. One of the three
slots is occupied by the MMC-E ETU. Two slots can be
The PSU provides the required DC voltages (-5V,
+5V, -24V) to ETUs installed in the CCU and to the
Y
devices connected to the CCU.
