equipment may result in the attached LAN equipment configuring to half-duplex mode, resulting in CRC
errors and packet loss. Refer to the interoperability section of this document for more information
Use only 75-ohm coaxial cables to attach the WAN Monitor to the DS3/E3 circuit. The monitor is attached
either inline with each WAN circuit cable or, alternatively, to a WAN tap. For inline use, the WAN cable
in one direction should be attached to the “In” WAN Port 1 and continues to the remote location via the
“Out” WAN Port 1. The other circuit direction comes to the “In” WAN Port 2 from the remote location,
and proceeds via the “Out” WAN Port 2 to the the local equipment. For use with a WAN tap, the “Out”
ports are not utilized and may be left open.
Once the monitor is receiving a valid TDM signal without alarms, the DS3/E3 Port LED will change from
orange to green.
Refer to the management chapter of this manual if HTTP or SNMP operating statistics are desired or to
change the default administrator password or administrative contact/location information.
Further HTTP management of the monitor via LAN is required in the following situations:
●
if using long (>68m) DS3 coaxial cables
●
to set CRC and scrambling to match the WAN circuit being monitored
●
to change the default administrator password. This is suggested, as configuration cannot be
modified after 5 minutes of any power cycle if the default password has not been changed
●
to change the management IP address of the unit
●
to set detailed LAN packet header format for packets from the WAN
There is no further configuration or setup required for the Monitor.
