General precautions
CS 1000 equipment is based on solid state circuitry that is sensitive to
static electricity and environmental conditions. Follow the precautions in
this chapter to avoid personal injury and equipment damage.
DANGER
To avoid the danger of electric shock, be careful when working
with power equipment and connections. Warning notices are
displayed and must be heeded.
Wear an antistatic wrist strap when handling circuit cards to prevent
damage caused by static electricity.
Circuit cardsHandle the circuit cards as follows:
•Wear an antistatic wrist strap before handling circuit cards.
•Handle the cards by the card stiffeners and edges only. Do not touch
the contacts or components.
•Keep the cards installed in the system as much as possible to avoid
dirty contacts and unnecessary wear.
•Set the cards on a protective antistatic bag. If an antistatic bag is
not available, hold the card, or set it in a card slot unseated from the
connectors.
•Unpack or handle the cards away from electric motors, transformers,
or similar machinery.

16 Communicating with the system
System terminal access for CP PII and CP PIV Call Servers
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 applications and devices that require them, such
as 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 Multipurpose Serial Data Link [MSDL] cards in
Large Systems.) You can telnet through the Terminal Server to individual
components on the ELAN subnet, and therefore obtain maintenance
access for each device. You can also access the Terminal Server from a
remote PC by dialing the onboard 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.
While the Terminal Server is needed for 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 Commissioning
(NN43041-310).
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.
Figure 1 "CS 1000Elocal and remote access system terminals" (page
17) shows a typical system terminal configuration to the Call Servers.

System terminal access for CP PII and CP PIV Call Servers 17
Figure 1
CS 1000Elocal 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 1000T (MG
1000T).
When a system terminal is installed directly on the CP PII or CP PIV Call
Server, it connects to the com 1 port.
When a system terminal connection is made to a CP PM Call Server, the
com (SDI) port is routed through the backplane of the shelf to the 50 pin
MDF connector. The NTAK19EC cable ships with the CP PM that adapts
the 50 pin MDF to a 25 pin DB connector for connectivity. A 25 pin null
modem cable is required to adapt the SDI port to a typical PC serial port.
Port0 is used for maintenance access. Port1 is for an external modem
connection.
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
(L-Adapter) provides an alternative to the faceplate maintenance port. For
details, see the Voice Gateway Media Card installation in Communication
Server 1000E Installation and Commissioning (NN43041-310).

18 Communicating with the system
Remote TTY
If a Media Gateway is using an SSC, the three SDI ports available on the
SSC card can be used as additional system TTYs. All applications on SDI
ports of the Call Server SSC, with the exception of a Low Speed Link
(LSL), are supported on the SDI ports of the MG 1000ESSC.
The purpose of a remote TTY is to access the Call Server from an MG
1000E. However, TTYs configured on the Call Server cannot access the
MG 1000E.
If the MG 1000Eis configured to be survivable, the SDI ports of the MG
1000ESSC can be used during survival mode, and function as a TTY
connected to a standalone CS 1000. However, the TTY has no access
to either LD 43 or LD 143. In survival mode, the SDI ports of the MG
1000Ecannot be used to access the Call Server. Either port on the
Signaling Server can be used for remote access.
System terminal access for Media Gateway Controller
Each Media Gateway Controller (MGC) installed in a CS 1000E has 3
serial ports: SDI0, SDI1, and SDI2. SDI2 is not available during system
initialization and therefore cannot be used to access installation menus.
MGC serial ports can be used for local debug purposes or configured as
system terminals in LD 17. Unlike the Small System Controller (SSC) SDI
ports, all MGC SDI ports are configured through software. The MGC does
not have DIP switches. Furthermore, the remote SDI feature of the MGC
eliminates the need for a terminal server or TTY on a system with MGC
architecture.
See Communication Server 1000E Installation and Commissioning
(NN43041-310) for more detail about configuring MGC serial ports.
System terminal access for MG 1000T
When a system terminal is installed locally with an MG 1000T, it connects
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.
System terminals connected to the MG 1000T cannot be used to access
the Call Server or MG 1000E.

System terminal access for MG 1000T 19
Figure 2 "MG 1000T local and remote access system terminals" (page
19) 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
(L-Adapter) provides an alternative to the faceplate maintenance port. For
details, see the Voice Gateway Media Card installation in Communication
Server 1000E Installation and Commissioning (NN43041-310).
MG 1000E10BaseT port
The MG 1000ESSC 10BaseT Ethernet port defaults to the disabled state.
To use the 10BaseT Ethernet port, assign the port a unique IP address,
and enable the port from the Call Server. The MG 1000E10BaseT
Ethernet port can run in Normal or Survival mode. In Normal mode, the
MG 1000Edoes not provide access to maintenance or alarm management.

20 Communicating with the system
MG 1000Ecard slot assignment
The MG 1000Econtains physical card slots numbered 1 to 10. When
configuring the CS 1000 system, the physical card slot numbers must be
transposed to loop, shelf, card.
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. The card’s hardware cannot support two devices
connected at the same time.
The terminal device should be configured to 9600, 8, N, 1. Configure the
flow control to "None" or a similar setting.
If the hardware flow control is enabled, you see information from the card
but the card does not respond to any keystrokes. If this happens, ensure
the flow control is set to "None", close the session, and reopen it.
Telephony Manager
Telephony Manager (TM) is a management server 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.
CS 1000 systems can be accessed directly using TM. Each CS 1000

TM provides alarm management and maintenance applications.
Alarm management
TM alarm management provides an alarm collection and a processing
center for multiple systems and devices. TM receives Simple Network
Management Protocol (SNMP) traps from the CS 1000 system, and stores
them in a circular log file on the TM Server. The TM Alarm Notification
application monitors incoming traps and notifies you of important events
and alarms.
