History: Monitor Tap CableSource of version: 4 (current){img src=http://www.ss7box.com/xyg_images/Rj45plug-8p8c.png align=center imalign=right}
The monitor tap cable allows connection of the receivers of two E1/T1 Sangoma ports to be used as monitors. The pinout diagram below shows a E1/T1 crossover tap cable. Another option is to build a straight cable tap that can be used with either straight or crossover cables. __References:__ [http://wiki.sangoma.com/Cablepinouts|Sangoma port pinout specifications]. __Materials:__ *Quanity 4, segment of [http://en.wikipedia.org/wiki/Category_5_cable|Cat5e] or [http://en.wikipedia.org/wiki/Category_3_cable|Cat3] cable. *Quantity 4, 8 position block connectors, aka RJ-45 connectors *Small tie-wrap *Cable splice insulation, for example **Heat shrink tubing **Tape **Silicone __Tools:__ *Wire cutters *Block connector crimp tool *Soldering pencil and solder {img src=http://www.ss7box.com/xyg_images/mon-tap-cable-po.jpg align=center imalign=right} __Procedure:__ #Identify wires used for positions 1, 2, 4, 5 in the 8 position block connector. Ignore the crossover side of the cable if a crossover tap is being made. #Label two cable segements as __Terminals__ #Label one segment as __Tap_A__ #Label one segment as __Tap_B__ #Create tap junction ##Bare the 1, 2, 4, 5 wires on the __Terminal__ segments ##Bare the 1 and 2 wires on both of the __Tap__ segments ##Twist the 1 wires together on the __Terminal__ segements; this is the wire 1 junction; repeat for the 2, 4, and 5 wires ##For __Tap_A__ ###Twist the 1 wire to the the wire 1 junction; solder ###Twist the 2 wire to the the wire 2 junction; solder ##For __Tap_B__ ###Twist the 1 wire to the the wire 4 junction; solder ###Twist the 2 wire to the the wire 5 junction; solder ##Bundle the junction with a tie-wrap #Install the 1, 2, 4, 5 wires in the corresponding pins on an 8 position block connector on one of the __Terminal__ segments #Attach 8 position block connector to remaining __Terminal__ segment ##If straight cable, install the 1, 2, 4, 5 wires in the corresponding pins on an 8 position block connector ##If crossover cable, ###Install wire 1 to connector position 4 ###Install wire 2 to connector position 5 ###Install wire 4 to connector position 1 ###Install wire 5 to connector position 2 # Attach 8 position connector to __Tap_A__ ##Install wire 1 of to connector position 1 ##Install wire 2 of to connector position 2 # Attach 8 position connector to __Tap_B__ ##Install wire 1 of to connector position 2 ##Install wire 2 of to connector position 2 {img src=http://www.ss7box.com/xyg_images/tap_cable_photo.jpg align=center} |
