At the left is an illustration of an example 66-block arranged for an alarm system and DSL splitter installation.
The exact arrangement of your block would vary according to your particular installation,
but would be similar to this example.
Note that this example is very similar to the example shown at
DSL Splitter Installation in a Star Topology,
except that it has been modified to show the alarm system connections.
Here are the connections shown on the example:
Click on the graphic for the wiring block to see a larger version of the graphic.
- The cable coming from the NID is terminated on binding post pairs 1-4
- Pair 1 is unused. (Would have been line one before DSL was installed.)
- Pair 2 is line 2 (if present).
- Pair 3 is unused.
- Pair 4 is the DSL line.
- The alarm system phone cable is terminated on binding post pairs 26 and 27
(at the top on the right side of the block).
- Binding post pairs 28 and 29 remain vacant to allow for changing to a four-pair cable.
- The cable to the splitter is terminated on binding post pairs 30-33.
- The DSL line is cross-connected from pair 4 of the NID cable to pair 4 of the splitter cable.
This pair would terminate on the "LINE" connection on the splitter.
- Pair 1 of the splitter cable would terminate on the "VOICE/PHONE" connection on the splitter and
is cross-connected to pair 1 of the alarm system phone cable (the "LINE" pair).
- Pair 2 of the alarm system phone cable (the "DROP" pair) is cross-connected to the first pair of all
the station cables to connect telephone line 1.
- Pair 3 of the splitter cable would terminate on the "DSL" or "DATA/MODEM" connection on the splitter
and is cross-connected to the cable going to the location where the DSL modem/router will be located.
- In the illustration, the cable on pairs 5-8 is used for the location for the DSL modem/router.
- Pairs 1 and 2 would go to a jack for connection of a telephone.
- Pair 3 would go to a jack for connection to the DSL modem/router.
(A dual jack faceplate could be used so that both jacks fit in the existing space.)
- Pair 1 of all the station cables are all cross-connected to the "DROP" on pair 2 of the alarm system phone cable.
Pair 2 of all the station cables are all cross-connected to pair 2 of the cable coming from the NID to provide connection
to a second phone line if it is active.
If your DSL line is "line two", this would be adjusted accordingly.
I would recommend installing the cross-connect for the second line even if you only have one line.
This will make it simpler and avoid confusion if a second line is added in the future.
