Section 360-381-802 Equipment Issue 2
Second Printing, August 2006
Telecommunications Group
3603-81 T1 Controller
Unit Installation Guide
GENERAL DESCRIPTION
Document Purpose
This document provides installation information
for the T1 with SNMP (T1-S).
Equipment Function
The T1-S 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.
Equipment Location/Mounting
Mount the T1-S in the primary slot of the 360-80.
One controller unit must be installed in the pri-
mary slot for proper system operation. Drop and
insert applications require a Secondary T1 unit
(issue 2 or later).
Performance History
This unit stores performance history for the last
30 days and over the last 24 hours in 15-minute
intervals. This performance history includes bit
error rate (BER), errored seconds (ES) and se-
verely errored seconds (SES).
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 Optioning 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 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 include
both the model number and its issue number
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 by
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.
CAUTION
Due to mechanical differences, the T1-S card
can only be installed in an Issue 3 or greater
ICB shelf.
3. Slide the unit into the shelf.
CAUTION
If there is already a rear panel installed on the
shelf, check for interference. The rear panel
may need to be removed and replaced with
the rear panel shipped w/the new unit.
Step Action
4. Once the unit is fully inserted, tighten the secur-
ing screw on the front panel.
5. Wire the unit per the wiring section.
6. The unit will perform a self-test to ensure that it is
compatible with the network management soft-
ware on the system.
7. After the self-test is performed, check the soft-
ware provisioning of the card using the craft inter-
face on the front of the controller unit.
Installing a Replacement Unit
If you are replacing a unit that is already in ser-
vice, make sure that the unit is the same as the
unit being replaced.
Step Action
1. Remove the wiring connectors from the front and
rear of the unit.
2. Unscrew the front panel 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.
Step Action
1. Connect T1 to the rear panel RJ48 jack (J1).
2. If using the Ethernet network management inter-
face on the rear of the unit, connect the system
to the other units using J2 and J3.
3. If you are using the composite clock, remove the
connector and wire the signal to the connector
labeled CCLK IN.
4. Reinstall the connector with the composite clock
signal wires.
5. Power and alarm should already be wired. If not,
see the documentation for the ICB shelf.
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.
The Address ID switch on the front panel is a mul-
ti-section switch for setting the system address on
the system management bus. This switch is used
if the system is connected together with other
360-80 systems into a central management con-
trol center. This switch allows the control center to
‘address’ the individual systems. See section on
network management for more information.
Table 1. LED Definitions
Label Color Status Indicates that...
POWER Green ON Unit is receiving power.
OFF The unit is not powered.
AR Red ON 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.
OFF Normal operation.
AY Yellow ON The unit is receiving a
YELLOW alarm condition
on the T1. This indicates
that a problem is up-
stream at some other de-
vice or network node.
OFF Normal operation.
TP Yellow ON The system is processing
the trunk signaling data
based on detected alarm
conditions.
OFF Normal operation.
LP Green ON The unit is in loopback.
This indication only oc-
curs during testing.
Flash-
ing
Valid external timing
source has been lost.
OFF Normal operation.
