Things you should know before you install a Telephone Patch Panel...
Telephone patch panel
with 25 Pair female RJ21X rear Telco connector. This
25 pair female connector would use a Male 25 pair cross connect cable to connect
from the patch panel rear to your other equipment. The other side of the 25 pair
cable can be whatever you need for a 25 Pair connector or a cable with no end on
it at all except for one Male end for the panel.
The front of the panel
has RJ45 8P8C style punch downs. Unlike Network Patch
panels, telco telephone voice panels have the RJ45 in the front but their
connected to a RJ21 25 pair connector in the rear, (that's 50 individual wires). They can be configured as a
single center pair RJ45 or even as 2 pair 4 wire RJ45. So be sure which panel
you need. 1 Pair center or 2 Pair center RJ45 connector. This voice grade panel
is specifically designed for voice applications like telephone systems.
Configured as 25 port or 48 port
panels. It mounts on standard 19" equipment
racks and accommodates top, bottom and side cable entry. Back panel
provides connectivity to a 25 Pair (RJ-21X) connector or connectors. The
number of 25 Pair Amphenol style connectors on the rear of the panel depends on the
number or RJ45 ports in the front and the number of active connections
chosen. The RJ45 in front can be configured as 2 wire (1 pair), 4
wire (2 pair), or 8 wires (4 pair), 568B.
The 25 Pair connector has 2 bolt down wire nuts to secure the male 25 pair that
can be attached to it.
These panels range from 2
live contacts in each of the RJ45 connectors in the front to
8 live contacts in the front. Depending on which one you
select. They are wired to a 25 Pair Amphenol connector in
the rear of the panel. Take particular note to the
designation of 8P8C or 8P2C. The 8P stands for 8 Position
and the 8C stands for number of live contacts on the RJ45.
So 8P2C would be 8 Positions or (RJ45), with 2 Contacts
wired or 1 pair, wired from each of the RJ45's to the
Amphenol's, in the rear.
This is what the male Amphenol looks like.
It snaps onto the female Amphenol connector on the back of the panels with the
Amphenol connectors. Usually this would have a 25 pair cable terminated onto it.
