•
Cost-effective signaling monitoring:
– grooms the signaling information over
a minimum number of links
– reduces the required number of
protocol analyzers
•
Most compact solution on the market
(half 19-inch, 1U-high chassis)
•
Integrates with any existing signaling
monitoring system
•
Direct grooming of any timeslot
•
Flexible – can extract different
timeslots
•
Wide variety of management options,
from ASCII terminal to NMS
RAD’s PRBm-20 probe is a cost-effective method
for centralizing network management and
reducing traffic monitoring costs. Rather than
installing expensive analyzers at small and
medium-sized locations or sending management
information from each E1/T1 line over a separate
link, the PRBm-20 concentrates up to 31
signaling timeslots and sends them to a central
protocol analyzer over a fully utilized link.
Cuts OpEx for maintaining services
The PRBm-20 reduces the cost of ownership of
advanced, revenue-generating services, such as
SMS messaging, instant messaging, call
forwarding, voicemail and international roaming,
by collecting signaling timeslots from many
leased lines and grooming them over a full link
to the protocol analyzer at the central site.
Reduces leased line costs
The PRBm-20 extracts the signaling timeslots
from up to eight links and grooms them onto
one E1/T1 or fractional E1/T1 output line. By
extracting any of the signaling timeslots from
the traffic, the PRBm-20 reduces the number of
lines required to connect to the protocol
analyzer.
Improves network performance
Service providers use the data from the
signaling timeslots to monitor the quality of the
connection and to detect network faults.
PRBm-20 cost-effectively transports signaling
information, enabling the service provider to
assure quality of service (QoS) at a competitive
price.
Complementary solution
The PRBm-20 can be used to expand any
existing monitoring method. It seamlessly
integrates with any T-connector or patch panel
used to divert the E1/T1 timeslots, and with any
standards-based protocol analyzer. The
PRBm-20 non-modular, standalone, E1/T1 probe
is the latest low-end addition to RAD’s signaling
monitoring solutions. RAD offers a range of
signaling monitoring devices, transporting
signaling timeslots from links at speeds of up to
STM-1 fiber optic links (see DXC family, pages
98-101).
