553-3041-500 Standard 1.00 September 2004
System terminal access for CS 1000E
Terminal Server
Because each CS 1000E Core Call Server provides only two ports for serial
devices, the Terminal Server is used to provide the necessary standard serial
ports for the applications and devices that require them (for example, for
printers and Call Detail Recording [CDR]). The Terminal Server is also used
to connect maintenance terminals and modems for support staff.
The Terminal Server provides an rlogin service that allows serial devices to
establish dedicated connections to pseudo TTY (PTY) ports on the Call
Server. (The Terminal Server therefore serves the same purpose as Serial
Data Interface [SDI] and Multi-purpose Serial Data Link [MSDL] cards in
Large Systems.) It is possible to telnet through the Terminal Server to
individual components on the ELAN subnet, and therefore obtain
maintenance access for each device. Users can also access the Terminal
Server from a remote PC by dialing the on-board modem.
As the Terminal Server is configured to automatically log in to the active Call
Server upon startup, only one Terminal Server is required for each Call Server
pair.
Note: While the Terminal Server is required to provide serial port access
to the Call Server, it can also be optionally configured to provide access
to Media Gateway 1000T (MG 1000T) serial ports for maintenance
purposes.
For more details on installing and configuring the Terminal Server, see
Communication Server 1000E: Installation and Configuration
(553-3041-210).
System terminal
When a system terminal is installed locally, it is typically connected to a serial
port on the Terminal Server. This ensures continued access to the active Call
Server. When a system terminal is installed at a remote location, a modem and
a telephone line are required between the system terminal and the Terminal
Server.

Communicating with the system Page 15 of 162
Communication Server 1000E Maintenance
Figure 1 shows a typical system terminal configuration to the Call Servers.
Figure 1
CS 1000E local and remote access system terminals
With the CS 1000E, a system terminal can also connect directly to the Call
Server, Signaling Server, Media Cards, and Media Gateway 1000Es
(MG 1000Es).
When a system terminal is installed directly on the Call Server, it connects to
the Com 1 port.
When a system terminal is installed on the Signaling Server, the rear serial
port is the primary port for maintenance and administration.
When a system terminal connects to an MG 1000E, it connects to the Small
System Controller (SSC) through an SDI port on the rear of the MG 1000E.
The Voice Gateway Media Card faceplate provides a female 8-pin mini-DIN
serial maintenance port for system terminal connection. The maintenance
port on the Shielded 50-pin to Serial/ELAN/TLAN Adapter provides an
alternative to the faceplate maintenance port. For details, see the Voice
Gateway Media Card installation in Communication Server 1000E:
Installation and Configuration (553-3041-210).

System terminal access for MG 1000T
When a system terminal is installed locally with an MG 1000T, it connects to
to the SSC card on the MG 1000T Core through a rear SDI port. The
NTBK48 three-port cable can be connected to the SDI port to provide a total
of three serial connections.
When a system terminal is installed at a location that is remote from the
MG 1000T, modems and a telephone line are required between the terminal
and the SDI port.
Note: System terminals connected to the MG 1000T cannot be used to
access the Call Server or MG 1000Es.
Figure 2 shows a typical system terminal configuration to the MG 1000T
Core.
Figure 2
MG 1000T local and remote access system terminals
With the MG 1000T platform, a system terminal can also connect to the
MG 1000T Expansion, Signaling Server, and Media Cards.
When a system terminal connects to an MG 1000T Expansion, it connects to
the SSC through a rear SDI port, in the same manner as the MG 1000T Core.

When a system terminal is installed at a remote location, modems and a
telephone line are required between the terminal and the SDI port.
When a system terminal is installed on the Signaling Server, the rear serial
port is the primary port for maintenance and administration.
The Voice Gateway Media Card faceplate provides a female 8-pin mini-DIN
serial maintenance port for system terminal connection. The maintenance
port on the Shielded 50-pin to Serial/ELAN/TLAN Adapter provides an
alternative to the faceplate maintenance port. For details, see the Voice
Gateway Media Card installation in Communication Server 1000E:
Installation and Configuration (553-3041-210).
Additional Serial Ports
The maximum number of serial ports used for maintenance, administration,
CDR, and traffic depends upon the number of MG 1000T Expansions
equipped. There can be up to three serial ports on the MG 1000T Core and up
to three for each equipped MG 1000T Expansion.
Connecting to the Media Card RS-232 maintenance port
Connect a serial cable either to the rear P2 connector or to the faceplate
connector, but not both at once. The card’s hardware cannot support two
devices connected at once.
The terminal device should be set to 9600, 8, N, 1. Set the flow control to
"None" or a similar setting.
Note: If the hardware flow control is enabled, users see information
from the card but the card does not respond to any keystrokes.
Optivity Telephony Manager
The Optivity Telephony Manager (OTM) is a management server that can be
used to configure and maintain the system. It collects and processes alarms
from the system, collects call accounting and traffic data, and acts as a
terminal server for multiple devices.

Page 18 of 162 Communicating with the system
553-3041-500 Standard 1.00 September 2004
With CS 1000E systems, the Call Server and the MG 1000T Core can be
accessed directly using OTM. Each is presented as a separate system in the
network.
Note: In OTM, the CS 1000E system appears as a Communication
Server 1000M Multi Group (CS 1000M MG) system, and the
MG 1000T appears as a Communication Server 1000S (CS 1000S)
system.
See Optivity Telephony Manager: System Administration (553-3001-330) for
details on how to use the OTM graphics-based user interface that incorporates
icons, pull-down menus, and a mouse for maintenance functions.
OTM provides:
• Alarm Management
• Maintenance Applications
Alarm Management
The OTM alarm management provides an alarm collection and a processing
center for multiple systems and devices. The OTM receives Simple Network
Management Protocol (SNMP) traps from the CS 1000E system, and stores
them in a circular log file on the OTM Server. The OTM Alarm Notification
application monitors incoming traps and notifies the appropriate users of
important events and alarms.
The OTM alarm management has the following components:
• A web-based alarm browser server to view alarms from multiple systems
and devices. HTML Help is provided for individual alarms.
• A Microsoft® Windows® alarm browser (Event Monitor) to view
CS 1000E system-specific alarms. Windows help is provided for
individual alarms.

Communicating with the system Page 19 of 162
Communication Server 1000E Maintenance
• An Alarm Notification application to provide a scripting language to
generate notifications on selected incoming traps. Notification types
include pagers, e-mail, and the forwarding of SNMP traps to an upstream
processor (such as Optivity Network Message Services [NMS]). The
notification is triggered by trap data such as alarm severity, device type,
and time of day. A Script Wizard application simplifies the creation of
Alarm Notification scripts.
• A PC Event Log and Viewer to view events and alarms generated on the
OTM Server and its Windows clients. This Windows application can
also generate SNMP traps based on event severity level.
Maintenance applications
With OTM Maintenance Windows, 37 maintenance overlays are grouped
into hardware-related windows that allow users to perform all the
maintenance tasks without having to remember or look up any overlay-based
commands. The OTM interface provides a comprehensive view of the
CS 1000E system hardware configuration.
OTM System Terminal
The System Terminal helps users to perform overlay-based tasks directly
through the TTY interface. The System Terminal provides online,
context-sensitive help for overlays, prompts, and error messages. The System
Terminal also provides a terminal emulation capability.
In the web environment, the Terminal Client provides the same functionality
as the System Terminal.
There are two versions of System Terminal to support two different
connection types — Ethernet or PPP and Serial — as follows:
• The Overlay Passthru is available on the OTM using Ethernet or PPP.
The Overlay Passthru only supports access to the overlays.
• The VT220 provides similar functions using serial connections, as well
as terminal emulation for all application modules.
Users can access overlays through the System Terminal and application
modules through VT220.

553-3041-500 Standard 1.00 September 2004
Element Manager
Element Manager is a simple and user-friendly web-based interface that
supports a broad range of system management tasks, including:
• configuration and maintenance of IP Peer and IP telephony features
• configuration and maintenance of traditional routes and trunks
• configuration and maintenance of numbering plans
• configuration of Call Server data blocks (such as configuration data,
customer data, Common Equipment data, D-channels)
• maintenance commands, system status inquiries, backup and restore
functions
• software download, patch download, patch activation
Element Manager has many features to help administrators manage systems
with greater efficiency. Examples are as follows:
• Web pages provide a single point-of-access to parameters that were
traditionally available through multiple overlays.
• Parameters are presented in logical groups to increase ease-of-use and
speed-of-access.
• The "hide or show information" option enables administrators to see
information that relates directly to the task at hand.
