3608-80 Secondary T1
Unit Installation Guide
GENERAL DESCRIPTION
Document Purpose
This document provides installation information
for the for the Secondary T1 Unit (ST1U). This
document covers model number 3608-80.
Equipment Function
The ST1U is part of the 360-80 Intelligent Chan-
nel Bank (ICB). It combines the functions of a
line interface unit (LIU) and a channel service
unit (CSU), allowing direct connections to public
T1 networks. The ST1U is a secondary T1 unit
for the ICB.
Equipment Location/Mounting
Mount the ST1U in the secondary (half-size) slot
of the 360-80. One T1−S controller unit (issue 2
or later) must be installed in the primary slot for
proper system operation.
Note: This unit must be mounted in an Issue
2 or later 360-80 shelf.
Control Interface
This unit is managed through the Network Man-
agement Interface (NMI), which controls the pro-
visioning of the unit and obtains status informa-
tion from the unit. Provisioning and status infor-
mation is described in the General section of
this document. For operation of this interface,
see the Network Management Interface docu-
mentation.
This unit will maintain its default provisioning
until that provisioning is altered through the NMI.
If this unit’s provisioning is changed, it will main-
tain the new provisioning even if power is lost. If
replaced with a new unit, the new unit will need
to have its provisioning changed to the same
provisioning as was set for the prior unit.
INSPECTION
Inspect for Damages
Inspect the equipment thoroughly upon delivery.
If the equipment has been damaged in transit,
immediately report the extent of damage to the
transportation company.
Equipment Identification
Charles Industries’ equipment is identified by a
model and issue number imprinted on the front
panel or located elsewhere on the equipment.
Each time a major engineering design change is
made on the equipment, the issue number is
advanced by 1 and imprinted on subsequent
units manufactured. Therefore, be sure to in-
clude both the model number and its issue num-
ber when making inquiries about the equipment.
STATIC-SENSITIVE
To prevent electrostatic charges from damaging
static-sensitive units:
Use approved static-preventive measures (such as
static-conductive wrist straps and static-dissipative
mats) at all times whenever touching units outside
of their original, shipped, protective packaging.
Do not ship or store units near strong electrostatic,
electromagnetic, or magnetic fields.
Always use the original static-protective packaging
for shipping or storage.
INSTALLATION
Attaching the Rear Panel
The rear panel of the unit should be installed
before all units are installed in the shelf, and be-
fore wiring begins.
Installing a New Unit
Step Action
1. If not already installed, install the rear
panel, screwing it to the appropriate
mounting locations on the shelf using
the provided hardware.
2. Insert the unit into the shelf, making
sure that the unit is aligned with the
card guides inside the shelf.
3. Slide the unit fully in to the shelf.
CAUTION
If there is already a rear panel
installed on the shelf, check for inter-
ference. The rear panel may need to
be removed and replaced with the
rear panel shipped with the new unit.
Step Action
4. Once the unit is fully inserted, tighten
the screw on the front panel to secure.
5. Wire the unit per the wiring information
in the wiring section.
The unit will perform a self-test to ensure
that it is compatible with the network
management software on the system.
6. After the self-test is performed, check
the software provisioning of the card
using either the craft interface on the
front of the controller unit or the network
management interface on the rear of the
controller.
Note: If a Secondary T1 unit is inserted into a
shelf while power to the shelf is on, the
T1 controller unit will reset.
Installing a Replacement Unit
If you are replacing a unit that is already in ser-
vice, verify that the two units are the same.
Step Action
1. Remove the wiring connectors from the
rear of the unit.
2. Unscrew the front panel securing screw
to release the unit from the shelf.
3. Using the card ejector, remove the unit
from the shelf.
4. Follow the procedure for installing a new
unit.
Wiring the Unit
Use the following steps to wire the unit for drop
and re-insert configurations.
Step Action
1. Connect the T1 from the WEST (towards
the network) 360-80 ICB, or equivalent,
to J6 of the ST1U.
2. Using the cable provided with the unit,
connect J5 to J1 on the T1-S.
3. Connect J4 of the ST1U to the input of
the next 360-80 ICB or to the EAST (to-
wards the customer termination) 360-80
ICB or equivalent.
Use the following steps to wire the unit for dual or
protection configurations.
Step Action
1. Connect the T1 from the EAST (towards
the customer termination) 360-80 ICB or
equivalent to J4 of the ST1U.
2. Connect J1 of the T1-S to the input of
the next 360-80 ICB or to the WEST
(towards the network) 360-80 ICB
or equivalent.
Front Panel Switch and LED Definitions
The Audible Alarm Cut Off (ACO) switch is a
pushbutton used to open the audible alarm con-
tacts from the 360-80 system. This switch will only
mask audible indications of present alarm condi-
tions—it will NOT clear the alarm. If a new alarm
occurs, the alarm will re-enable.
Table 1. LED Definitions
Label Color Indicates That...
POW-
ER
Green the unit is receiving power
AR Red The unit is detecting a red
alarm on the T1 interface
caused by a loss of signal
(LOS) or a loss of framing
(LOF) or out of frame
(OOF) condition.
AY Yellow The unit is receiving a yel-
low alarm condition on the
T1. This indicates that a
problem is upstream at
some other device or net-
work node.
TP Yellow The system is conditioning
the signaling data based on
detected alarm conditions.
LP Green The unit is in a loopback
condition. This indication
only occurs during testing.
BY-
PASS
Green The unit is in a bypass con-
dition.

OPTIONING
This unit comes from the factory with default provi-
sioning, which can be changed through the Net-
work Management software (NMS), SNMP Net-
work Node Manager (NNM) or the craft terminal
interface. See the NMS, NNM or craft terminal
interface documentation for procedures. Each unit
has its own provisioning options. The provisioning
options are as follows with the default optioning
noted:

ALARMS
This unit provides for alarm contacts for audible
and visual alarms. Access to the alarm contacts is
provided on the 360-80 shelf. Pressing the audible
alarm cut-off (ACO) switch clears the alarm indica-
tion for the audible alarm contacts, stopping the
audible notice of the alarm (the alarm itself is NOT
cleared by pressing the ACO switch). See the
shelf documentation for information on wiring. The
unit generates alarm indications based on the con-
figuration of the alarm registers. See the network
management documentation for more information.
