General Information
1.1 Functional Description
MX-2100/2104 is an advanced, highly versatile user-configurable modular TDM
(Time Division Multiplex) system. The MX-2100/2104 system provides an efficient
and cost-effective method for transmitting data, voice and fax over digital data
services. Access to these services is provided over a variety of standard interfaces
(V.35, RS-530/V.36, RS-232/V.24, X.21, Standard DDS, codirectional G.703,
ISDN, fiber optic, T1, and E1), at data rates ranging from 9.6 to 1536 kbps.
Bandwidth utilization efficiency is 98.5%.
Main System Features
The MX-2100/2104 system can be equipped with various types of input/output
(I/O) modules that provide the required interface for the user data, fax, and voice
channels. The series of I/O modules includes:
• High-speed synchronous data modules operating at a rate of 2.4 through
614.4 kbps – the KHS series of modules
• Low-speed data modules (300 bps to 57.6 kbps or 64 kbps) synchronous and
asynchronous data channels, including statistical multiplexing modules – the
KLS series of modules
• ISDN interface modules – the KHS.U series and KVF.4/S0 series
• 2W and 4W multiple voice channel interface modules that can directly
connect to PBX lines and two-wire telephone sets – the KVC series of modules
• 2W and 4W interface voice/fax low bit rate KVF.4 and KVF.8 modules
• T1 and E1 PBX trunk interface KVF.5 and KVF.6 modules
• Token ring extender module, KTRE
• Ethernet Bridge/Router module, KMBE
• Bypass and multidrop module, KDI (not applicable for MX-2104).
Detailed information on the specific MX-2100 modules can be found in the
separate module Installation and Operation Manuals.
The 3U high MX-2100 unit can be equipped with up to 12 I/O modules. 1U high
MX-2104 unit can be equipped with up to 4 I/O modules.

MX-2100/2104 Installation and Operation Manual Chapter 1 General Information
Functional Description 1-3
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.

1-4 Functional Description
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.
