DXC-100

• DXC-100 can also aggregate

Ethernet traffic (for example, ISP or

corporate traffic) from several

remote sites via different trunks into

one stream, by using the

channelized router module.

BASIC UNITS

• The basic DXC-100 chassis is

6U-high (10.5 inches), and is NEBS

Level 3 certified. The chassis

includes eleven I/O slots for plug-in

interface module sets. Each module

set consists of a front main module

and a rear interface module. The

power supply and system manager

modules are not provided with the

chassis and must be ordered

separately. Optional redundancy for

the system manager and power

supply modules is available.

• The chassis can be mounted in a

19-inch wide rack. Optional

23-inch flush and 23-inch center

mount brackets are also available.

• Up to 8 DXC-100 units can be

stacked in a star topology. Nest 1 is

a master unit, while nests 2 to 8 are

slave units. The master unit has a

different main system manager

module (DXNM) and an additional

expansion module (DXCC). The

slave units have the same main

system manager module (DSMC.2),

and an additional stack controller

module (DXLC).

• When a standalone unit is

expanded into a stack, all of its

modules are used and no resources

are wasted.

SYSTEM MANAGER MODULES

• A standalone DXC-100 requires one

or two DSMC.2 half-height main

modules and one DSMC.2 full-height

interface module.

• Nest 1 in a DXC-100 stack requires

one or two (recommended)

half-height DXNM main modules with

one full height DSMC.2 interface

module and one or two

(recommended) full-height DXCC

main and interface modules.

• Nests 2 to 8 require one or two

DSMC.2 half-height main modules

and one or two (recommended)

full-height DXLC main modules. The

DSMC.2 interface module is optional

and intended for use only when the

DXC-100PSX is used. For each of the

DXLC modules, a D8E1T1 interface

module can be installed at the rear of

the chassis, to provide additional 8

E1/T1 ports each.

DSMC.2 Main Module

• A standalone unit, as well as Nests 2

to 8 of stacked units, use the

half-height DMSC.2 system

management main module, placed

in a specially designed slot. Two

such slots are available for optional

system redundancy. The DSMC.2

module can generate a Stratum 3

clock source.

DSMC.2 INTERFACE MODULE

• A single full-height interface module

supports up to two DSMC.2 or

DXNM main modules and is

rear-mounted into a dedicated slot.

The interface module contains

management 10/100BaseT Ethernet

and supervision terminal ports,

phone line (connected to internal

modem) and critical/major/minor

alarm dry contacts.

DXNM Main Module

• Nest 1 of the stacked units uses the

half height DXMN system

management main module instead

of the DSMC.2 module. The DXMN

module is placed in a specially

designed slot. Two such slots are

available for optional system

redundancy. The DXNM module

provides a Stratum 3 or external

clock to all units. The interface

module for Nest 1 is the same as for

a standalone unit (DSMC.2).

DXCC and DXLC Main and Interface

Modules

• Matrix expansion modules are the

DXCC module for Nest 1 and the

DXLC module for Nests 2 to 8. The

DXCC and DXLC modules are

connected via an external cable.

The DXCC module creates a

transparent switch fabric for a

non-blocking 3/1/0 cross-connect

between any ports of the stacked

units.
