DXC-100

REDUNDANCY (OPTIONAL)

• DXC-100PSX is an optional

redundant protection switch unit

adjunct to the DXC-100. It provides

automatic protection services for

E1/T1 and/or DE3/DT3 services in a

user-selectable N:1 manner. It

occupies only 3U of vertical space

directly above the DXC-100 chassis

and features fail-safe switch and fan

operation.

• DXC-100PSX supports up to a 10:1

protection ratio for the D8E1T1

module, up to 6:1 and an

additional 3:1 ratio for DE3 or DT3

modules in a single 11-slot unit.

Each DXC-100 unit can use only

one DXC-100PSX.

• The system manager module,

DXC-100PSX-NC is connected to

the DXC-100 unit by a special

cable. The system manager module

(one per unit) and the –48 VDC

power supply modules (one or two

per unit) must be ordered

separately.

I/O MODULES

A DXC-100 standalone unit holds

up to eleven module sets consisting

of a front main module and a rear

interface module. Up to eight DXC-

100 units in a stack accommodate a

maximum of 86 module sets.

• DSTM-1 is a single-port STM-1

module that provides SDH Path

Terminating Equipment (PTE)

functionality for DXC-100. The

DSTM-1 module can transmit and

terminate any timeslot from up to

84 T1 or 63 E1 channels per STM-1

facility. Mixed E1 and T1 traffic

applications are supported. 1:1

redundancy is achieved when used

together with an STM-1 module set

in an adjacent slot.

• DOC-3 is a single-port OC-3

module that provides SONET PTE

functionality for DXC-100. DOC-3

can transmit and terminate any

timeslot from up to 84 T1 links per

OC-3 facility. 1:1 redundancy is

provided when used with a

companion OC-3 module set in an

adjacent slot.

• DT3 is a single-port T3 interface

module that multiplexes any

timeslot from up to 28 T1 links or

21 E1 links into a single T3 stream

with either C-bit parity or M13

framing. Mixed (E1 and T1) traffic

applications are supported as per

ITU G.747. The module has integral

BERT and supports loopback

diagnostics. Hardware redundancy

up to 6:1 is available via

DXC-100PSX.

• DE3 is a single-port E3 interface

module that allows DXC-100 to

transmit and terminate an E3 link. It

also multiplexes and demultiplexes

any timeslot from up to 16 E1 links.

The module has integral BERT and

supports loopback diagnostics.

Hardware redundancy up to 6:1 is

available via DXC-100PSX.

• D8E1T1 is an 8-port E1/T1 module

that supports up to eight E1 or T1

links in any combination with D4,

ESF, or G.70x framing and AMI,

B8ZS, or HDB3 line coding. The

module has an integral BERT and

supports loopback diagnostics.

Hardware redundancy up to 10:1

is available via DXC-100PSX.

• D8HS is an eight-port

n × 56/64 kbps data module with

eight high-speed synchronous data

channels. The electrical interface for

each port can be configured

independently for RS-530,

RS-530A, RS-449/422, RS-232,

V.35 or X.21 interfaces at the

system console.

• DROUTER is a 32-channel (2 Mbps)

channelized router hub module that

allows DXC-100 to perform the

functions of a channelized,

multiprotocol router. DROUTER

can be used for inband

management of remote units. It

supports up to 32 individual

channels (1 to 32 timeslots) for

IP/IPX routing, including multiple

protocols and additional features,

such as NAT. An integral SNMP

agent is provided. The rear interface

card supports 8-port 10/100BaseT

LAN hub functionality and detects

status of up to three external

contact closures.

MANAGEMENT

• DXC-100 can be managed via the

following options:



ASCII terminal



Telnet



RADview-PC™ or

RADview-HPOV™ SNMP central

network management system.

Note: An activation key licence must be

ordered to manage DXC-100 in

RADview.

• Local and remote configuration and

diagnostics reduce operating

expenses, eliminate costly

technician visits, and maximize

network performance and uptime.

• Inband management, that enables

management of other RAD remote

products, is supported via the

DROUTER module.

• DXC-100 utilizes an embedded

SNMP agent that provides basic

system resource monitoring, event

notification, diagnostics,

performance monitoring, and

provisioning. Per the appropriate

RFC standards, SNMP uses UDP

protocol to send and receive data.

The agent can be configured to

allow only selected and authorized

devices to view or change

information. DXC-100 supports

upload and download of its

configuration.

• The set of read/write parameters

allows for basic slot configuration,

circuit/connection set-up for all

five cross-connection maps,

system clock and source

assignment as well as D8E1T1,

DE3, DT3 and D8HS data

application module provisioning.

A set of read-only parameters

allows for monitoring system

status and alarms, as well as

performing limited diagnostics.
