Signaling Monitoring Probe

• Concentrates up to 31 E1 or 24 T1 timeslots
• Protected grooming according to ITU-T G.772 recommendation
• Most compact solution on the market (half 19-inch, 1U high chassis)
• The E1 interface meets ITU recommendations G.703, G.704, G.706 and G.732
• The T1 interface complies with AT&T TR-62411, ANSI T1.403 and AT&T Pub. 54016
• Wide variety of management options, from ASCII terminal to NMS
• Local and remote loopbacks on the uplink

• Cost-effective signaling monitoring:
  • grooms the signaling information over a minimum number of links
  • reduces the required number of protocol analyzers
• Integrates with any existing signaling monitoring system
• Direct grooming of any timeslot
• Improves network performance
• Flexible – can extract different timeslots

RAD’s PRBm-20 signaling monitoring 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.

The PRBm-20 signaling monitoring probe 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. The analyzer then reads the signals that identify each user, checks the user profile and activates the appropriate response.

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.

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.
