Redundancy options

The optional redundancy on common logic, main

link and power supply ensures a high level of

system reliability on Megaplex hubs.

R2 support

The Megaplex also includes R2 support with

transparent MFC/decadic implemented within the

main link. This allows the customer to connect a

legacy R2-PBX to a digital (E1 CAS) PBX, thus

extending the lifespan of existing equipment.

TDM over IP support

Megaplex incorporates RAD’s TDMoIP technology

in the ML-IP main link module. This enables all

existing TDM services to be transported over

packet switched networks. With the ML-IP

module, the Megaplex can be connected in a

daisy-chain topology where multiple Megaplex

units can be cascaded together. TDMoIP support

also allows the Megaplex to operate opposite

the IPmux family of TDMoIP gateways. Along

with TDMoIP, Megaplex supports Resilient Fast

Ethernet Ring (RFER) with under 50 msec ring

restoration capabilities. Up to 40 E1 or 50 T1

TDM circuits can be connected per Fast Ethernet

ring or daisy chain.

The addition of TDMoIP functionality further

expands the broad scope of solutions supported

by the Megaplex family and IPmux family. For

more information about the TDMoIP concept,

please refer to chapter 7.

Management options

The Magaplex-2100 and Megaplex-2104 feature

flexible management capabilities, including local

management via an ASCII terminal (RS-232). In

addition, remote management can be performed

either inband using the network or user ports or

out-of-band using a dedicated management

port, while maintaining separation between

management and user traffic via the use of

VLANs. Advanced FCAPS (Fault, Configuration,

Administration, Performance, Security) and

diagnostic tools are provided by RADview-EMS,

RAD’s carrier-class element management

system, and/or by RADview-SC/TDMoIP, RAD’s

network management system, via an SNMP-

based GUI.

The devices can also be accessed directly, using

Telnet.

Diagnostics

Megaplex incorporates test features for rapid fault

detection and easy maintenance. Once in operation,

all system and I/O modules undergo self-testing,

and problems are reported to the management

system. Local and remote loops may be performed

on each channel and on the main links.

Any timeslot can be selected for BERT/tone

injection. In addition, a loop can be initiated per

any timeslot.

The ABCD status of any voice channel can be

captured with a single click (signaling monitoring).

Alarms

Alarm information is stored in the common logic

module and is automatically read by the

management system from any node. Up to 256

alarms can be stored in a queue, and a maximum

of 1,024 alarms can be stored in a file on the PC,

to be read by the management system.

System modules

The common logic module stores configuration

and event information, and uses a SLIP/PPP or

Ethernet connection to communicate with the

management station via an SNMP agent. Flash

EPROM for remote software download, Telnet and

an ASCII craft terminal are also supported.
