both PIIC modules are active AND at least one Gigabit Ethernet interface is active. The CDM-760
acts as a multiplexor/demultiplexor in MultiStream Mode.
C.1.1 PIIC Conditional Availability
Appendix F. OPTIONAL HIGH-SPEED PACKET PROCESSOR
Figure C-1. Optional High-Speed Packet Processor (No PIICs Allowed)
A CDM-760 that is equipped with the High-Speed Packet Processor (Figure C-1) cannot
accommodate operation of PIIC synchronous traffic data modules (G.703 T3, E3, STM-1, OC-3,
etc.).
When the CDM-760 is factory-equipped with the optional High-Speed Packet Processor card (it
is also available as a field upgrade using CEFD Kit KT-0020958), the card installs into the modem
rear panel chassis physical space otherwise occupied by the PIICs. The PIICs therefore cannot be
co-installed.
C.1.2 Typical PIIC Module Installation
Figure C-2. Typical PIIC Module Installation
Do these steps to install the optional PIIC module(s) (Figure C-2):
Step Task
1 Remove the PIIC slot blank panel(s) by loosening the captive thumbscrews.
2 Install the PIIC module(s) into position using the chassis’ internal card guides. Slide
the module straight back into the chassis until the module is firmly plugged into the
mating receptacle(s).
3 Secure the captive thumbscrews of the module(s).
