Typical Piic Module Installation; C.1.1 Piic Conditional Availability - Comtech EF Data CDM-760 Installation And Operation Manual

Appendix C
CDM-760 Advanced High-Speed Trunking Modem
Any PIIC module supported by the CDM-760 can be used in any slot. In Single Stream Mode, a
single PIIC module is active and no other interfaces are active. In MultiStream Mode, one or
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

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).
