Manual.
When the CPU-E( ) ETU is removed for long term
storage, set the SW2 switch to OFF. This will prevent
the battery from constantly discharging. The battery,
when fully charged, will retain memory contents for
approximately 7 days.
Switch 1 (SW11 is the reset switch. When depressed,
this momentary switch interrupts all service in
progress causing a second initialization. This switch
should not be used in an operating system unless
absolutely necessary. The CPU-E( 1 ETU must be
installed in the CPU slot of the ESE-32B-1 CCU.
B. CPU-EC( ) ETU DIP SWITCH
The CPU-EC( ) ETU has a third switch (SW3) that is
made up of three DIP switches (1, 2, and 3). Only dip
switch 1 is used. When DIP switch 1 is in the OFF
position, it is in the MF mode. When DIP switch 1 is in
the ON position, it is in the KF mode.
The MF mode allows a trunk to be seized by two
methods:
1. Depressing a line Key.
2. Dialing an access code.
The KF mode allows trunk access by using Line keys
only.

The mode selected, (MF or KF), must correspond to the
applicable FCC Registration Number (Refer to
Chapter 1 of this manual).
C. TSW-E ETU
The TSW-E ETU (refer to Figure 200-18) contains
three switches, two LEDs, one connector, and two RCA
phono plugs. Switch 1 (SWl) is the reset switch.
Depression of this momentary switch causes all service
in progress in the ESE-32B-1 CCU, to be interrupted.
This switch should not be used in an operating system
unless absolutely necessary.
The LEDs indicate module memory working status.
Under normal operating conditions, they are fluttering
to indicate memories being activated. When SW1 is
depressed, the LEDs momentarily turn OFF. Anytime
the CCU is disabled, the LEDs are OFF.
Connector CN2 is used for data transmission between
the TSW-E and the MMC-E ETUs; the cable provided
on the MMC-E ETU is plugged into this connector.
MOH IN/OUT (SW2) is used to select the MOH source
from either internal or external. When the music chip
is used for MOH source, set this switch to the IN
position. If an external MOH source is connected, set
this switch to the OUT position. (For external MOH
source connection, instructions are provided in Section
270, Optional Equipment Connection).
