The 24 E1 Coax to Telco Impedance Matching Balun Panel provides 75-120 ohm conversion for 24 E1 channels (Tx and Rx). The panel conforms to ITU-T G.703, matching the impedance and signal characteristics of up to 48 unbalanced 75 ohm coax connections with up to 24 balanced 120 ohm twisted pair connections.
Only 1U high, the 19 inch rack mount balun panel is available with BNC, 1.6/5.6 (Small Siemens) or Type 43 (BT43, SMZ) coax connectors. Twisted pair connectors are 50 way shielded female Telco (AMP Champ).
This panel is also available with 21 E1 circuits.
See the 24 E1 TTR panel if you require the Transmit and Receive circuits on separate Telcos.
