Addendum
3.4.1 Description
(Paragraph 3) Delete the following sentence:
Modems not part of a backup pool will not be learned.
3.4.6 Configuration Copy
The Configuration Copy is a feature that enables a user to store/retrieve up to five modem and interface card
configurations in non-volatile memory. These are in addition to the current running configuration.
The interface card configurations are tagged to the slot, and are stored in the switch. The modems, on the
other hand hold their own settings. The user can copy from and copy to any configuration in memory
including the current running configuration. Source and destination configurations must be different.
When instructed to copy a configuration, the switch sends a command to the modem to copy the
configuration, and if successful, the switch updates the slot configurations as well. If the destination
configuration is the current configuration, the modem re-initializes itself and uses the new settings. The
switch interface card is only updated when the destination configuration is the current configuration.
A user must be careful not to copy onto the current configuration unless that is desired, interruptions in traffic
will occur.

Section 1 - RCS10 Redundant Communication System Description
1.1 Introduction
As shown in Figure 1-1, Radyne ComStream's RCS10 is
a complete, self-contained modem system with all
modems, terrestrial interfaces and redundancy switch
functions included in a single equipment cabinet that is
10 rack units high (17.5 inches). This compact and
versatile common equipment package is unique and
offers unsurpassed performance, reliability and flexibility.
In addition to full support for Intelsat's IDR/IBS services,
the system may be operated in closed networks.
The built-in M:N Redundancy Switch is an intelligent
microcomputer controlled system, capable of controlling
up to ten DMD10 modems in a variety of configurations.
The switch can be operated automatically, in which case
an automatic back-up of a failed on-line modem occurs
after a preprogrammed delay. The switch may also be
operated manually, allowing the operator to manually
switch in the backup unit. Front panel controls and
indicators provide for auto/manual configuration, as well
as display of online/off-line status information for all
modems in the redundancy configuration.
All switch and modem operating parameters, such as
variable data rates and selectable IBS/IDR framing, are easily set and changed by the operator.
The modem and redundancy switch monitor and control functions are available at the front panel of
the system (Refer to Section 3). All functions may also be accessed through a terminal or a
personal computer via a serial link (RS485 or Ethernet) for complete remote monitoring and control
capability.

When used with the optional IFC10 IF Combiner/Splitter system, the RCS10 system provides all of
the signal combiners and splitters, terminations and interconnecting cables that are necessary to
connect any combination of up to nine active modems to nine independent uplink and nine
independent downlink transponders. Refer to Figure 1-3, RCS10 System Block Diagram for a basic
overview of the RCS10 system components.
1.2 External Reference
The External Reference Module, located in slot 10 on the far left side of the RCS10 rear panel (See
Figure 1-2), has one External IF Reference input which is distributed to all ten DMD1O modems.
Each modem’s on-board system oscillator can be individually locked to the external reference.
Additionally, the external reference module can be equipped with a 10-7 high stability reference
oscillator which is distributed to all ten DMD10 modems, thus providing a low-cost high-stability
option. An External IF reference output is also provided for distribution to other equipment.
Also, the external reference has one BNC clock input which is distributed to all ten modems. Each
modem control can independently select this external clock as its Tx clock and/or RX buffered
clock source.
