Note: Using shielded cabling is an electromagnetic interference (EMI) requirement for CVX 600 E1 network configurations.

Note: For UK installations using 75 ohm E1 coax, a balun is needed to connect to the 120 ohm impedance of the CVX switch. Nortel does not recommend a specific balun panel for this application.
