VCL-PG, 16/32 E1 Packet Monitoring Solution

Description

Valiant's ‘VCL-PG, 16/32 E1 Packet Monitoring Solution’ may be used to groom up to 16 / 32 x E1 channels and convert their payload to RFC 5086, RFC 5087 and RFC 4553 compliant Ethernet Packets.

The VCL-PG, 16/32 E1 Packet Monitoring Solution is equipped with a highly reliable clock recovery mechanism for low jitter and wander control, even under variable network conditions.

The 16/32 x E1 Port ‘VCL-PG, 16/32 E1 Packet Monitoring Solution’ provides 4x Gigabit combo Ethernet ports for Ethernet link redundancy, and QoS by implementing 802.1Q based VLAN, Differentiated Services (Diffserv/DSCP), Port based Priority and 802.1p packet priority classification protocols for network optimization. Port mirroring is also available so that the copy of same data may be output to duplicate servers for “Server” redundancy.

Applications of VCL-PG, E1 Packet Monitoring Solution

The VCL-PG, E1 Packet Monitoring Solution has been designed for “lawful data intercept’ and “call monitoring” applications and may be used to convert the payload of the E1 channels that are being monitored to RFC compliant Ethernet packets, which can then be routed to / monitored by “lawful data intercept’ and “call monitoring” Servers that are used for national security applications.

Key Features – Explained

  • Port Based Priority (Classifying Services) – Port based Priority feature allows the user to assign priority to the individual Ethernet ports, so that traffic can be regulated according to the port on which that service is connected. The user may also assign highest priority to TDM (E1/E3) traffic and Ethernet services on a lower priority.
  • VLAN Based Priority (Classifying Services) – VLAN based Priority feature allows the user to assign priorities to different VLANs carrying various types of services / traffic according based on user categories and preferences. The user may assign highest priority to TDM (E1/E3) traffic and Ethernet services on a lower priority. User may also configure which TDM link should be given preference over the other TDM links when the uplink bandwidth falls below a particular threshold.
  • Flow Control in an Ethernet Packet Networks: (Regulating Traffic) - Flow Control feature allows the user to regulate Ethernet traffic flow to minimize packet loss due to data bursts.
  • Port Mirroring – Provide duplicate copies of monitored data on a 2nd Ethernet Port.
