Introduction Revision 4
CDM-760 Advanced High-Speed Trunking Modem MN-CDM760
1–7
• 100-240 VAC Primary Input Power Supply with Press-fit Fuse Holder
1.2.3.2.2 Rear Panel Optional Features
These Data Interfaces (for optional hardware and/or FAST-enabled operation) are available from
Comtech EF Data:
•
(1X) Optical Gigabit Ethernet interface via the J7|OPTICAL cage, which accepts the optional
SFP [Small Form Factor Pluggable] Module.
• (2X) PIIC (Plug-In Interface Card) slots accommodate these data interface options:
o
G.703 E3/T3/STS-1 (34.368/44.768/51.84 Mbps).
o
OC-3 Single Mode and Multi Mode (155.52 Mbps).
o
STS-1 Copper (155.52 Mbps).
o
DVB ASI (Asynchronous Serial Interface) (up to 210 Mbps).
o
Additional PIIC data interface options (HSSI, etc.) will become available upon request.
•
(1X) Optional High-Speed Packet Processor card can be installed into the modem chassis
space otherwise occupied by the PIICs. This option provides (from left):
o
(1X) CLI (Command Line Interface) RJ-11 port for implementing factory commands.
o
(1X) P0 | MGMT RJ-45 Gigabit Ethernet routed interface/management port.
o
(4X)
P1 | DATA
through
P4 | DATA
RJ-45 Gigabit Ethernet bridged interface ports.
• (1X) J2|REDUNDANCY DB-9M EIA-232 connector for interoperability with a separately
purchased Comtech EF Data redundancy switch:
o
For 1:1 redundant applications, the CDM-760 is supported by the CRS-170A Redundancy
Switch for L-Band operation, or the CRS-180 Redundancy Switch for 70/140 MHz
operation.
o
M:N redundancy support is available using the CRS-500 M:N Redundancy System. The
CRS-500 can be used only for CDM-760 1:10 operation with the 10/100/1000 BaseT
Gigabit Ethernet and G.703 E3/T3/STS-1 data interfaces. The CRS-500 may not be used
with any other data interface, nor can it be used for redundancy in MultiStream mode.
These Rear Panel Rack Support Brackets Kits are available from Comtech EF Data:
•
KT-0000168 4” Rear-Mounting Support Brackets Kit
•
KT-0000195 10” Rear-Mounting Support Brackets Kit
This Power Interface Option is available from Comtech EF Data:
• 48 VDC Primary Input Power Supply with Screw-in Fuse Holders.
These
FUTURE
Power Interface Options will be available from Comtech EF Data:
•
24 VDC BUC 90 Watt Power Supply (AC Input or DC Input versions). FUTURE
•
48 VDC BUC 150 Watt Power Supply (AC Input or DC Input versions). FUTURE
1.2.4 Verification
The CDM-760 includes many test modes and loopbacks for rapid verification of the correct
functioning of the unit. Of particular note is the IF loopback, which permits the user to perform
a quick diagnostic test without having to disturb external cabling.
