line 2 and the remaining pins 4,5,7 & 8 are can transport native PoE or are unused.
 Attaching cabling and devices to the Enable-IT 850 CPE Extended Ethernet.
Attach your remote LAN device to the 850 CPE unit LAN ports with Ethernet patch
cord provided. Attach your local LAN to the 8950 DSLAM LAN ports with Ethernet
patch cord provided. Attach the power adapter to the 850 CPE units and power
supply to the 8950 DSLAM. Your equipment should now be powered up and
functioning.
LED indicators will provide visual operational status of the 850 CPE units.
Sync - Slow to fast flicker on power up – indicates negotiation of a link.
Solid Green LED indicates link established and rapid pulse is traffic.
Pwr - Solid Green LED indicates that both units are receiving 5v power.
Mode - Solid Yellow LED on CPE unit only – No LED lit on CO
ACT - Yellow LEDs – Lit solid indicates the presence of local LAN
– Blinking indicates the presence of local LAN traffic
 For troubleshooting, first examine the backbone wiring pair and make sure you have solid
connections. The Interlink Sync LED will be lit solid Green with rapid pulsing on each 850
CPE unit to show proper connection and pairing. If the Interlink Sync LED Link is flashing
slow to fast and never goes solid …. Then follow the steps below:
1) Make sure your wiring is straight through and not connected to any Telco punch
down block; If so remove from the block and use Telco butt clips to bridge wire.
2) Check for a firm connection of the RJ-11 connections in each 850 CPE
unit and 8950 DSLAM, and power is applied to both the DSLAM and CPE units.
3) You can easily isolate any issue by performing an out of the box test confirm either the 850 CPE
or your wiring. It is possible an outside interference has been introduced into your wiring.
Performance Settings
A DIP Switch is provided on the left side of each unit for setting line
performance attributes.
If the Interlink cabling is more than
1,900ft / 580m – Set DIP Switch 3 up
For 17a mode. This optimizes
faster symmetrical throughput at higher
distances.
If the Interlink cabling is less than 1,900ft
580m - the DIP switch 3 must be down For 30a mode
(set to ON) position for the unit to work properly.
Technical Support
Enable-IT OEM Technical Support is available directly to customers and distributors. All
support requests are processed through the online support portal. This allows us to provide
assigned support ticket numbers in order to bring closure to any technical issues.
Default DIP settings

850 CO – DIP position 1 up (OFF)
DIPs 2-4 down (ON)
DIP 1 – CO/CPE mode
DIP 2 – Fast/Interleave mode
DIP 3 – 30a/17a mode – short distance or
long distance mode
DIP 4 – 6dB/9dB – 9dB mode cleans up the
signal noise ratio on the telephone wiring
