Figure B-4. CDI-40 Rear Panel View (PL/10883-4 Shown)

For the PL/10883-3 Module (standard non-redundant applications):
• Tx-ONLY 1:1 Redundancy – Rx output ('Rx | J2' and '1:1 Rx | J3') is the
standard ASI level.
• Full duplex (Rx/Tx) 1:N Redundancy – Rx output ('Rx | J2' and '1:1 Rx |
J3') is the standard ASI level.
For the PL/10883-4 Module (standard non-redundant applications, excluding '1:1
Rx | J3'):
• Tx only, Rx only or full duplex (Tx and Rx) 1:1 redundancy (see Sect.
B.3.4).
o Rx output 'Rx | J2' is standard ASI level
o Rx output '1:1 Rx | J3' is higher so the standard level is delivered
after a 3 dB combiner (see Sect. B.3.4).
• Full duplex 1:N redundancy (excluding '1:1 Rx | J3').
