MX-2100/2104 Installation and Operation Manual Chapter 1 General Information
The MX-2104 system can be equipped with only one main link. The 3U high
MX-2100 system can be equipped with two main link modules. Two main link
modules in an MX-2100 system, can be used in several ways:
• To provide hot-standby redundancy (backup) for the main link, with automatic or
manual switchover in case one of the links fails. For maximum flexibility, MX-2100
allows the preparation of a different configuration for use on the backup link. The
backup link can also use a switched data circuit. The switched circuit can be
established on a PSTN line, using analog modems, or on an ISDN line using an S
or U interface.
• To provide two independent links from the same MX-2100 enclosure. The two
links can operate at different data rates. The dual-link mode can also be used
for providing the equivalent of hot standby protection to critical data channels
(by enabling the priority bumping feature).
• To provide multidrop and bypass capabilities (using a dedicated KDI module).
In addition to main link redundancy, the MX-2100 system reliability can be further
enhanced by installing an additional power supply unit in the enclosure. The
power supplies share the load current, therefore when one of them fails or its
input voltage is disconnected, the other takes over the full load without
disturbance to MX-2100 operation.
The MX-2100/2104 system provides flexible system timing options, with several
main link, and channel timing modes.
The main link timing modes are DTE, DCE, and external DCE. In the DCE and
external DCE modes, the timing reference source can be selected by the user:
• Internal oscillator
• External (timing locked to one of the data channels)
• The other main link module (provided a KDI module is installed).
In addition to the main timing source, a fallback source can be selected. When the
timing mode is DTE or external DCE, buffers are inserted in the main link signal
paths, to absorb the expected jitter and timing instabilities. Normal buffer size is
±8 bits; for operation over satellite links, the receive buffer size can be increased to
±256 bits.
The timing modes available for the data channels are programmable, thereby
permitting each channel to be configured as either DCE (supplies receive and
transmit clocks to the user's equipment), DTE1 (supplies the receive clock and
accept a transmit clock), or DTE2 (accepts receive and transmit clocks from the
user's equipment), with buffered retiming of the received data. Connection to the
national network and to common-carrier data lines is also supported, with the
external clock selectable as the source for system timing.
For modules with ISDN, T1, E1, and fiber-optic interfaces, a loopback timing
mode is available. This mode enables locking the MX-2100 timing to the accurate
timing provided by the network to which the interface is connected.
Functional Description 1-3
Chapter 1 General Information MX-2100/2104 Installation and Operation Manual
System Supervision and Configuration
The MX-2100 system is designed for unattended operation. A complete collection
of operating parameters configures the MX-2100 system and each of its modules.
This collection of operating parameters is determined by a database. This database
is stored in the non-volatile memory of the MX-2100 control module. MX-2100
can store two different databases, and can be configured to switch automatically
between the databases, in accordance with a predetermined daily schedule
("day/night" operation), or to use one of the databases only in case of switching to a
backup link.
MX-2100 supervision and minimal configuration functions can be performed from
its front panel, using three push-buttons and an LCD display. For more detailed
information, refer to Local Management on page 1-33.
MX-2100 stores alarms detected during operation in a buffer. The buffer serving
the front panel LCD can store one alarm of each type. The buffer for alarms to be
sent to a supervision terminal can hold up to 100 alarms. During regular operation,
a front panel indicator lights to indicate if there are any alarms in the alarm buffer.
The local operator can then review the contents of the alarm buffer on the front
panel LCD display, and can delete old alarms related to events that are no longer
present in the system.
In addition to the alarm buffer, the front-panel LED indicators display in real time
the main link and power supply status and alert when test loops are present in the
system. The front panel LED indicators can also be used to monitor on-line a
selected user channel. The monitored functions are transmit and receive data
activity, and the state of the RTS and DCD control lines (or E and M lines for voice
channels).
Local MX-2100 Management
A local MX-2100 can be managed by any of the following:
• MX-2100 front panel using push buttons and an LCD
• ASCII terminal connection to the local MX-2100
• TELNET connection to the local MX-2100. The connection can be via SLIP or
via an Ethernet LAN. The local MX-2100 requires an IP address. For
information on assigning an IP address, refer to the DEF AGENT command in
the Command Set Description appendix.
• SNMP network management station connected to the local MX-2100. The
connection can be via SLIP or via an Ethernet LAN. The local MX-2100
requires an IP address. For information on assigning an IP address, refer to the
DEF AGENT command in the Command Set Description appendix.
Remote MX-2100 Management
A remote MX-2100 can be managed either in-band or out-of-band. For both, the
remote MX-2100 requires an IP address. For information on assigning an IP
address, refer to the DEF AGENT command in the Command Set Description
appendix.
1-4 Functional Description
MX-2100/2104 Installation and Operation Manual Chapter 1 General Information
In-Band Management
In-band management of a remote MX-2100 is performed via the local MX-2100
and the data frame. A connection to the local MX-2100 can be made through:
• An Ethernet LAN
• A SLIP connection.
In both cases, management can be performed via TELNET. Some of the bandwidth
of the main link between the two MX-2100s is used to relay the management
information.
In a “V” configuration, any one of the three MX-2100s can be considered the local
MX-2100. The other two MX-2100s can be managed through the local MX-2100.

• Using a network management station or TELNET via a SLIP connection to the
remote MX-2100. The remote MX-2100 requires an IP address. For
information on assigning an IP address, refer to the DEF AGENT command in
the Command Set Description appendix.
• Using an ASCII terminal via a modem connection to the SP port.
Diagnostic Capabilities
The MX-2100 system provides extensive diagnostics, supervision and maintenance
capabilities for easy maintenance and rapid detection and location of faults.
MX-2100 diagnostics include automatic self-test upon power-up, and on-line
monitoring of critical functions. The system generates time stamped alarm
messages that cover all the significant system events. The time stamp is provided
by a real-time clock with battery backup. The system operator can then perform
comprehensive testing on each type of module, to determine the cause of the
alarm messages and return the system to normal operation.
Various types of test loops are provided, including modem loops 2 and 3 per
ITU-T Rec. V.54 for rapid isolation of the fault area, tone injection for rapid testing
of voice interface modules, and pseudo-random sequence transmission test for
checking the proper operation of data interface modules, and detection of bit
errors.

Common Logic Modules
The MX enclosure requires one KCL.2 type common logic module. The main
functions of the KCL.2 module are control of:
• Multiplexing/demultiplexing operations
• System management
• Interfacing with the optional external system management.
The KCL.2 module stores the MX-2100 database in non-volatile memory
(NVRAM). The configuration information stored in the NVRAM is downloaded to
the module installed in MX-2100 upon turn-on or after system reset. Therefore,
during troubleshooting activities, it is possible to temporarily remove the KCL.2
module from the MX-2100 enclosure without disrupting system operation. If it is
necessary to replace the KCL.2 module, the database can be transferred to a new
module by installing the NVRAM taken from the original module in the
replacement module.

interfacing, the KML module performs the multiplexing and demultiplexing
functions and provides the timing signals used by the other modules installed in
the enclosure. Two KML modules are necessary for dual link configurations and for
main link redundancy.
The following main link interface modules are available:
KML.1 - V.35 main link interface module
KML.2 - V.24/RS-232 main link interface module
KML.3 - V.36/RS-422/RS-530 main link interface module
KML.4 - X.21 main link interface module
KML.5 - G.703 codirectional main link interface module
KML.6 - Standard DDS CSU/DSU main link interface module
KML.7 - T1 main link interface module
KML.8 - E1 main link interface module.

MX-2100/2104 Installation and Operation Manual Chapter 1 General Information
KML.10 - ISDN main link interface module. The module can be ordered in two
versions:
• KML.10/S with ISDN S-type interface. The "S" interface operates as Terminal
Adapter (TE side), intended for connection to standard Network Termination
(NT) unit.
• KML.10/U with ISDN U-type interface. The "U" interface operates as Network
Termination (NT side) unit, intended for connection to standard Line
Termination (LT) unit.
KML.F - Fiber-optic main link interface module (not for MX-2104). The module
can be ordered with various types of optical interfaces (laser or LED transmitters
for single-mode and multi-mode fiber-optic cable).
For more information, see each main link module’s Installation and Operation Manual.
Power Supply Modules
The MX-2100 enclosure can accept one or two KPS type power supply modules.
Several types of power supply modules are available:
KPS.3 - 25W power supply module for -48 VDC power
KPS.4 - 50W power supply module for 100 to 240 VAC mains
KPS.5 - 25W power supply module for -24 VDC power
KPS.6 - 56W power supply module for 100 to 240 VAC mains
KPS.7 - 56W power supply module for -48 VDC mains.
Two KPS modules are necessary for redundancy: when both modules are
operational, they share the load, whereas in case of failure or loss of input power
the remaining module continues to supply the power alone and there is no
redundancy. Switch-over is automatic and does not disturb normal operation.
The MX-2104 enclosure includes one power supply. The available types are:
• AC - 30W power supply for 100 to 240 VAC mains
• 48 - 40W power supply for -48 VDC mains.
In addition to power supply modules, the MX-2100 enclosure supports one
KM-Ringer module, for providing line feed and ring voltages for voice channels
and phantom feed for ISDN lines. This module is available in AC (115 to 230 VAC)
and DC (-24 VDC or -48 VDC) input voltage versions. The KM-Ringer can be
installed as a plug-in module for MX-2100, or located on shelves or desktops.

Option Modules (not for MX-2104)
The 3U MX-2100 system can accept two types of options module:
KAI
Alarm indication module for installation in the options position, or in any I/O slot.
The KAI includes indicators similar to those located on the MX-2100 front panel.
These indicators repeat all the relevant MX-2100 front panel indications on the
rear panel, and thus complement the indicators available on the rear panels of the
other modules. Maintenance activities are thus expedited, as all the MX-2100
indications become readily available on one side of the equipment.
KDI
Bypass and multidrop module. The KDI module can be installed in the option slot,
or in any I/O slot. The KDI module enables direct transfer (bypassing) of a group of
main link frame bits, in both directions, between the two main links of MX-2100.
Channels that are not bypassed are connected to I/O modules of MX-2100.
The KDI module is available in two versions:
• KDI version: supports only the bypassing function
• KDI/M version: also includes a data channel interface for one multidrop channel.
The multidrop channel is compatible with the data channels of the KLS.1/NEW
low-speed data module, and supports data rates in the range of 0.3 to 64 kbps. As
is standard practice in a multidrop application, the receive path of the local
multidrop channel continuously receives the data transferred in its allocated
bandwidth on the desired main link (the same data is also bypassed to the other
link, to make it available downstream), but its transmit path is connected to the
main link only when the RTS line in the local interface is asserted.
I/O Modules
For more information, see the option module’s Installation and Operation Manual.
MX-2100 supports up to 12 user-selected I/O modules. MX-2104 supports up to 4
user-selected I/O modules. Both units can accept any combination of the following
types of I/O modules with power supply limitations.
KVC.1 - ADPCM or PCM voice interface module, provides two voice channels. For
more information, refer to the KVC.1 Installation and Operation Manual.
