Warrant y Policy
Comtech EF Data products are warranted against defects in material and workmanship
for a specific period from the date of shipment, and this period varies by product. In most
cases, the warranty period is two years. During the warranty period, Comtech EF Data
will, at its option, repair or replace products that prove to be defective. Repairs are
warranted for the remainder of the original warranty or a 90-day extended warranty,
whichever is longer. Contact Comtech EF Data for the warranty period specific to the
product purchased.
For equipment under warranty, the owner is responsible for freight to Comtech EF Data
and all related customs, taxes, tariffs, insurance, etc. Comtech EF Data is responsible for
the freight charges only for return of the equipment from the factory to the owner.
Comtech EF Data will return the equipment by the same method (i.e., Air, Express,
Surface) as the equipment was sent to Comtech EF Data.
All equipment returned for warranty repair must have a valid RMA number issued prior
to return and be marked clearly on the return packaging. Comtech EF Data strongly
recommends all equipment be returned in its original packaging.
Comtech EF Data Corporation’s obligations under this warranty are limited to repair or
replacement of failed parts, and the return shipment to the buyer of the repaired or
replaced parts.
Limitations of Warranty
The warranty does not apply to any part of a product that has been installed, altered,
repaired, or misused in any way that, in the opinion of Comtech EF Data Corporation,
would affect the reliability or detracts from the performance of any part of the product, or
is damaged as the result of use in a way or with equipment that had not been previously
approved by Comtech EF Data Corporation.
The warranty does not apply to any product or parts thereof where the serial number or the
serial number of any of its parts has been altered, defaced, or removed.
The warranty does not cover damage or loss incurred in transportation of the product.
The warranty does not cover replacement or repair necessitated by loss or damage from
any cause beyond the control of Comtech EF Data Corporation, such as lightning or other
natural and weather related events or wartime environments.
The warranty does not cover any labor involved in the removal and or reinstallation of
warranted equipment or parts on site, or any labor required to diagnose the necessity for
repair or replacement.

Preface MN/CRS300.IOM
The warranty excludes any responsibility by Comtech EF Data Corporation for incidental or
consequential damages arising from the use of the equipment or products, or for any inability
to use them either separate from or in combination with any other equipment or products.

CRS-300 1:10 Redundancy Switch Revision 16
Introduction MN/CRS300.IOM
The CRS-300 1:10 Redundancy Switch (referred to throughout this manual as the Switch)
provides fully automatic protection of traffic circuits in the case of equipment failure. The user
can configure the CRS-300 to back up (replace) a Traffic modem when a Unit Fault and/or a
Tx/Rx traffic Fault occurs.
Intended for hub applications, the CRS-300 is compatible for use with the Comtech EF Data
Modems specified in Table 1-1. While the Switch is capable of controlling any of these specified
modems, note that it is important that only one type of modem may be connected within a given
Switch system; this is because the redundant modem must operate identically to the configured
traffic modem.
A key feature of the CRS-300 architecture is its ability to allow th e redundant modem to ‘bridge’ a
traffic modem. The Switch automatically configures the redundant modem to match the bridged
modem’s configuration. The Switch also copies th e bridged modem’s terrestrial transmit clock/data
and routes it to the redundant modem. When using the CRS-280/280L, it additionally routes the
bridged modem’s Rx IF. Because this live traffic is used at all times to verify performance, no
external test equipment is needed to determine the health of the redundant modem.
Construction features: The CRS-300 is modular in construction – all replaceable modules insert
into slots in the back panel. This includes the controller, Redundant Modem Interface (RMI),
Traffic Modem Interfaces (TMIs), and Power Supply Units (PSUs).
Because power consumption is below 30 watts for a fully populated Switch, no fan cooling is required.
Key Reliability Features: The CRS-300 incorporates the following key reliability features:
• Twin, independent, AC or DC power supplies.
• Traffic Modems with differing data types can all be supported by the Redundant Modem
– the exception to this is the CDM-Qx/QxL and, with some limitations, the CDM-625.
• Primary traffic paths are maintained, error-free, when power is removed.
• TMIs can be completely removed from the CRS-300, with cables still attached, and
traffic is not interrupted or affected.
• RMI and/or TMIs can be replaced without disturbing other traffic circuits.
Interfaces: The CRS-300 supports all of the modems’ available interface types, which include
EIA-530/-422, V.35, Sync EIA-232, ASI, Balanced or Unbalanced G.703, LVDS, Single-port
Ethernet Bridge Mode, and HSSI.
Ease of Connection: Connection to the traffic modems and the redundant modem is remarkably
easy – rack cabling is simplified and the number of potential failure points is reduced.
For the CDM-570/570L, CDM-600/600L, or CDM-625: When using the multi-protocol
interface, only a single cable – carrying all data signals, alarm information and the serial remote
control interface – is required for each modem.
If the G.703 interfaces are used: One additional cable is required.
For the CDM-Qx/QxL: These modems require an additional RS-485 multi-drop cable from the
Switch to all modems to provide remote control interface capability.
For EIA-232/-485 M&C User connections: A direct user-to-modem serial EIA-232/-485
communication connection is not permissible when connected to the CRS-300. The user must
instead connect to the DB-9 "Remote" connector on the CRS-230 System Controller (installed on
1–2

Introduction MN/CRS300.IOM
the CRS-300). For detailed information on remote addressing schemes, refer to Appendix B.
ADDRESSING SCHEME INFORMATION.
TMI Monitoring: Terrestrial user clock and data signals to and from a traffic modem are routed
through a TMI via a set of relays. This is arranged so that the de-energized (unpowered) state
connects the data signals directly through to the traffic modem. If the power supplies to the
system are lost, or if a traffic-carrying TMI is removed, no interruption of the traffic occurs. It
should also be noted that, in normal circumstances where the redundant modem is not in service, no
data is carried through the CRS-300 backplane – all data is routed via the TMI.
CRS-350 Option: Where protection of the IDR overhead signals (backward alarms, audio ESC,
data ESC, etc.) is desired, the CRS-350 module may be added.
CRS-280/280L Option: The CRS-280 (70/140 MHz) Switch is required when one or more
modem within the redundancy group connects to more than one up/down converter. This occurs
when the modems connect to more than one transponder on the same antenna polarization, or
when modem redundancy needs to span two or more polarizations or antennas.
Operation with the CRS-280L (L-Band) Switch is necessary when one or more modems within
the redundancy group connect to the other polarization of the antenna or to multiple antennas.
Refer to the CRS-280L 1:N Redundancy Switch Installation and Opera tion Manual
NOTE
for detailed information about this optional switch.
The system may forgo using the CRS-280/280L and, in its place, passively combine or split the
modulator outputs and demodulator inputs when the entire group of modems is connected to the
same up/down converter. In these applications, the CRS-300 mutes the faulted modem’s Tx
carrier and enables the standby unit’s carrier.
Figure 1-2 depicts an operational schematic for the CRS-280/280L interface.

Compatibility Notes:
1. The CDM-625 Open Network Satellite Modem, with its available CDM-600 Emulator Mode,
serves as an operationally transparent replacement unit for the CDM-600/600L Open Network
Satellite Modems.
2. The CiM-25, Comtech EF Data’s low-cost Internet Protocol (IP) Monitor & Control (M&C)
interface for existing CEFD modems, is not compatible for use on modems operating within a
CRS-300 redundancy system. Taking this prohibition of use under further consideration, the
CiM-25 should not, under any circumstances, be connected to the Remote port on the
CRS-300’s CRS-230 Controller card for control of the Switch and modems.
