Plug In Your Cable
Terminal Block
If you are using the terminal
block, straight or crossover
cable are both supported.
Installing new, shielded,
24 gauge copper wire
is recommended.
If using RJ11 cable, straight
or crossover cable are both
supported. (Only pins 3
and 4 are actually used.)

Ethernet extenders work
in pairs. Set one as the local
(Loc) unit and the other as the
remote (Rem) unit. It doesn’t
matter which one is which.

Only one power source
is required. Redundant
power is supported.
The DIP switch is on top of the device.
Note: Extender must be connected to a receiving extender or a network switch.

Troubleshooting
What is the latency for the EIR-EXTEND?
These figures vary according to the VDSL speed. For a
typical speed of about 25Mhz, the small packet size
of 64 bytes is around 72 µs if two units are connected
back-to-back. For a maximum packet size of 1518 the
latency will be in the range of 430 µs with the same
configuration.
What type of cable should I use
to connect a pair of EIR-EXTENDs?
Wire size and length are not the only factors that
affect the connection. The surrounding environment
has an even bigger impact. VDSL is an analog signal
that is sensitive to noise. If there is a magnetic field
or electrical noise around the wire performance
will be affected.
Our stated distances are based upon ideal scenarios.
We use regular Gauge 24 wire and a dedicated
line. Real-world distance will vary according to the
conditions encountered on a user’s site. Filters and
splitters will affect performance, as will sharing the line
with voice.
What kind of protection can I use
between a pair of EIR-EXTENDs
on the RJ11 port?
The EIR-EXTEND’s common mode output does not
exceed 5VDC. Regular telephone line surge protection
should be good enough (48VDC). Common mode
capacitor impedance should be lower than 3pf or
performance will be affected (reducing speed and link
capability).
We do not provide telephone line surge protectors
at this time.
