Chapter 2: Quick Set-up
Attach the gateway to a power source. The front panel lights should illuminate. Green is normal; orange
indicates an error.
Attach an Ethernet UTP5 cable from your LAN equipment to the RJ-45 LAN Port 2. The gateway can
perform automatic cross-over vs straight-through cable adaptation. The LAN 2 light will change from
orange to green if a properly negotiated link has been established. The network equipment attached to
the LAN port of the gateway should be set for autonegotiation mode in order to allow the gateway to
negotiate a 100Mbit full-duplex connection. Disabling autonegotiation or using old LAN 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
Attach two 75-ohm coaxial cables from the Port 2 BNC connectors of the gateway to the input and output
connectors of your E3 or DS3 link. Once the gateway is receiving a valid TDM signal, the DS3/E3 Port
LED will change from orange to alternating orange/green. The DS3/E3 Port LED will change to constant
green when a full, unerrored pseudowire connection has been established between the two gateways with no
TDM alarms at either end.
Further HTTP management of the gateway via LAN is required in the following situations:
if using fractional rather than full-speed E3/T3
●
if using unframed E3/T3
●
if more than two E3Switch gateways exist on the LAN.
●
to configure for minimal latency or maximum jitter tolerance
●
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.
There is no further required configuration for the gateway.

Front Panel Indicators
All Indicators:
Green indicates normal operation.
Orange indicates an error condition.
Black indicates a disabled port.
DS3/E3 1/2:
Green if the unit has a bidirectional TDM circuit established with no alarm conditions.
Orange indicates an alarm or loss of the incoming TDM connection.
Flashes orange/green if incoming circuit is OK but an outgoing alarm condition is being transmitted.
BER:
Green if OK.
Orange flash for each BPV bit error.
Orange steady for absence of DS3/E3 receive signal, loss of frame lock onto receive bit-stream,
LAN1/2:
Green when a properly negotiated 100/1000BaseTX Full-Duplex or SFP LAN connection exists.
Flashes black each time a packet is received on this port.
Orange indicates no valid connection.
drive-level fault on transmit cable, or excessive receive bit errors.
