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 Channel 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 primary 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 severely errored seconds (SES).
Control Interface
This unit is managed through the Network Management Interface (NMI), which controls the provisioning of the unit and obtains status information from the unit. Provisioning and status information is described in the Optioning section of
this document. For operation of this interface,
see the Network Management Interface documentation.
This unit will maintain its default provisioning
until that provisioning is altered through the NMI.
If this unit’s provisioning is changed, it will maintain 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 before 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 securing 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 software on the system.
7. After the self-test is performed, check the software provisioning of the card using the craft interface on the front of the controller unit.
Installing a Replacement Unit
If you are replacing a unit that is already in service, 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 interface 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 contacts from the 360-80 system. This switch will only
mask audible indications of present alarm conditions—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 multi-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 control center. This switch allows the control center to
‘address’ the individual systems. See section on
network management for more information.

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 indication for the audible alarm contacts (pressing this
switch does not clear the alarm). See the shelf
documentation for information on wiring. The unit
generates alarm indications based on the configuration of the alarm registers. See section on Network Management for more information.
NETWORK MANAGEMENT
Default Unit Configurations
The ICB stores all configuration settings in the
T1-S. The T1-S is shipped from the factory with
the default settings, which may be changed
through the network management interfaces.
Changing Unit Configuration Locally
The ICB can be configured through the front panel
craft terminal (MGMT) jack. See the craft terminal
interface documentation for procedures.
Network Management
The 360−80 channel bank can be managed via
two different interfaces over the Ethernet connection on the rear of the T1−S card. The Network
Management System (NMS) interface is GUI
based and requires proprietary software operating
on the managing PC. The Network Node Manager
(NNM) interface is SNMP based and requires
SNMP network manager software operating on
the managing PC. See NMS and NNM documentation for more information.
To use either interface from outside the T1 controller’s LAN a “gateway” address must be defined.
The gateway address should be the same as the
IP address of the LAN’s router.
Front Panel RJ11 Jack
The RJ11 jack on the front of the unit is the local
craft/control port. The default interface is an
RS232 connection that defaults to 9600 baud, 8
bits, 1 stop and no parity. The interface through
the control port is VT-100. VT-100 operation on a
PC requires VT-100 emulation software. An IP
address and IP subnet mask must be configured
through the craft interface before the unit will communicate with the NMS/GUI or SNMP. To communicate with SNMP, the SNMP community table
must also be configured. See the network management section or the network management interface documentation for more information.
A cable (03-200542-0) is available to connect between the front panel RJ11 jack and a DB-9 connector.
T1 Jack
The RJ48 connector on the rear of the T1-S is for
the primary T1.
Rear Panel RJ45 Jack
The J2 RJ45 jack on the rear of the unit is for interfacing to a network management control center
using SNMP or proprietary NMS/GUI software
over Ethernet.
