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
Network management provides centralized
control of all network nodes, including interface
configuration, connection setup, alarms, and
management.
Extensive network management is provided on
multivendor management platforms using
Megaplex with standard SNMP protocol.
Megaplex provides the control and monitoring
required in large networks using the RADview
element manager platform. The Megaplex is also
supported by RADview-SC/TDM and RADview-
SC/TDMoIP, allowing the service allocation to be
provided at the click of a mouse button.
All parameters are user-programmable for up to
10 independent configurations (10 databases
per unit). All configurations are saved in non-
volatile memory.
Alarm status and system configurations are
available at all times. Multiple Megaplex hubs
can be controlled from a single PC or UNIX
workstation.
The Megaplex can be managed also via the
RADview Service Center (for path management) or
by third-party path management applications via
CORBA interface. (For more details see page 202.)
Programming and setup of a remote Megaplex
device is accomplished:
•
Out-of-band, through the Ethernet port
•
Out-of-band, through the supervisory port of
the remote unit, over a modem link or FRAD
•
Inband, using a dedicated timeslot, dedicated
Frame Relay, PPP or TS0
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).
