E1 8 PORT 120/75 COAX DIST.PNL The Bal/Unbal BNC Distribution Panel provides 8 external BNC interfaces to the 120 ohm E1 ports of an E1 card. It may be used with any of the following cards: 90-4671-x2 (E1 CR), 90-2541-x2 (E1 UFR), 90-2544-x2 (E1 CFR), 90-2517-x2 (E1 CE), 90-6351-x2 (E1 CR), 90-7277-x5 (16 port E1 FR) , 90-9729-x1 (16 port VoP), or 90-9169-01 (32 Port MS). A D78 cable (90-8269-01 for ESE and 90-2766-02/22 for 7470) connects the line card to the panel which provides a BNC connector for each port Tx and one for each port Rx. The panel is 1 vertical unit (VU) high rack-mountable device. This panel was changed in 2003 (PCN# 9541) to remove the grounding option in order to comply with the EU 2003 directive for EMC Class B emissions. The outer conductor is permanently tied to the chassis.
