For monitoring HDLC IP packets on a DS3/E3 circuit. This device decodes IP packets encapsulated in an HDLC format on the WAN and presents them in Ethernet format at its copper, 100Base-TX LAN port for monitoring or recording by attached LAN equipment. Management of the unit is through the same LAN port (on a separate configurable VLAN if desired). Two WAN, BNC receive ports allow monitoring of each WAN cable. Two WAN, BNC transmit ports allows the device to be inserted inline without a tap, if desired, to pass-through incoming DS3/E3. For out-of-band management through a second LAN port, order our SFP upgrade accessory and SFP copper transceiver. Detailed screen-shots, information, manuals and multi-card options are available here. Rackmount brackets included.
