PowerHouse Systems has developed
and deployed a balun based panel that can support both E1 and T1
transmissions which make for easy patching. Some companies offer
two different panels for these applications but after exhaustive
testing with some of the largest telephone companies in the world
we have proven and perfected panels that handles 120 ohm and 100
ohm interfacing with 75 ohm coax, or 120 ohm to 93 ohm RG62 , 100
ohm to 93 ohm RG62 , and 120 ohm : 50ohm and 100 ohm : 50 ohm over
While there are different tolerances
for E-1 120 ohms (+/-15 ohms) and T-1 runs at 100 ohms (+/- 10 ohms,)
Transmission Return Loss is the critical performance spec that reflects
the characteristic impedance mis-matching. We have proven that a
10 or 15 ohm tolerance of impedance creates just miniature deviation
of the transmission Return Loss. Worst case we could expect a Return
Loss of 14 db which is acceptable to most all transmission systems.
E1/T1 Panel - This panel has fully shielded RJ45's and is loaded
with 24 ports of complete inline pin to pin wire management for
instant patching on your rack. These panels are also available in
Cat 5e and Cat 6 feed through if higher bandwidth performance is
We can develop your custom E1/T1
panels and Connectivity. We welcome your OEM challenges today.
