Introduction

1.0 Description

This manual discusses the Radyne SFC1800A Synthesized Frequency Upconverter (Figure 1-1).
This high-qu al ity, rack-mountable sa tellit e upco nverter is intended for use in medi um-to-large
earth station installations where multiple carrier uplinks need to be established . The SFC1800A
Upconverter is ready to be configured into a variety of backup switch configurations, which
include 1:1, and 1:N (where N is a maximum 8) configurations.

Figure 1-1. SFC1800A Upconverter Front Panel

The SFC1800A Upconverter is a DBS-Band, 125 kHz reso lution synthesi zed satellite upconverter
capable of converting either a 3 6 MHz bandwidth, 70 MHz IF inpu t or optionally a 72 MHz
ban dwidth, 140 MHz input to a DBS-Band uplink i n the range of 17.30 - 18.40 GHz.

All of the configu r ation, monitor, an d contr ol functions are available at the front panel. Operat ing
parameters such as frequency, channel, gain, gain offset, and switch settings (backup only) can
be readily set and changed at the front panel. Additionally, all functions can be accessed with a
terminal or personal com puter via a serial li nk (RS-232, RS-485, or Ethernet) for complete remote
monitoring and control ( M &C) capabili ty. Extensive fault monitoring wit h masking capability,
along with time and date stamped event st or age is ava i lable.

The units m onitor l ocal oscillato r ( LO) phase-locked loop faults in the converter at all times dur i ng
operat ion. If a fault i s detected, the converter immediately g oes int o the S tandb y Mode. If
multiple converters are configured t o provide backup protection switching, a summar y fau lt will
sig nal the backup, which will put itself online and r estore the failed circu it.

The RF Hardwar e consists of a broadb and synthesizer, a fi xed freq uency phase l ocked oscillator,
and the first and se cond converter modules. The broadband syn thesizer provides the
synt hesized local oscillator for the conversi on from L-Ban d to RF output. The LO that tunes from

14.80 - 15.9 0 GHz performs this conversion. The second mi xer co nvert s the 70 or 140 MHz IF
input to L-Band. A fixed frequency First IFLO performs this frequency conversion.

A 20 dB gain co ntrol attenu ator at t he L-Band of the second m i x module controls the power out of
the converter. This attenuator is capable of 0. 1 dB reso lution through a software li near
interpolat ion of 1 dB cal i bration values.

Introduction SFC1800A Synthesized Frequency Upconverter

The SFC1800A Upconverter have been designed to provide performance that meets or exceeds
all in dustry standards i n effect today for satell i te com muni cation s earth stati on frequency
converter eq uipment fou nd worldwide. In addition to providing robust performance , th e
SFC1800A Upconverter are loaded with feat ures t hat will provide ease of integration and
operation.

1.1 Protection Switch Versatility

Radyne SFC converters featur e ‘plu g-and-play’ ease of installation wit h th e RCU101 1:1 or th e
RCU1 08 1:8 Redundancy Control Units. All convert er s can be plugged in to the b ackup slot and
assume the r ol e of protection switch con troller. The backup converter l earns and stores the
frequ ency, gain and channel settings of the p r imary conver ters. The backup converter can be
operat ed automatically, in which case an automatic backu p of a fault ed, online C onverter occurs
after a user-programmed delay. The Backup may also be operated manually, all owing the user
to m anually switch i n the B ack up Uni t. The Fron t Panel controls and indica tors p r ovide for
automatic/man ual configurat ion, as well as display of onlin e/offline status information. In the
event the stored settings of the Prim ar y Converter are changed, th e backup co nverter will not i fy
the user.

All circu i ts are p r otected upon installation of the swit ch an d completion of the lear ning process.
This eli min ates the need for complicated soft ware configurations that m i ght oth er wise lea ve a
circuit vu l nerabl e. Likewise, rep l acing a failed converter is as sim ple as plugging in a
replacement.

1.2 Chain Switching (Optional)

Chain Switching is availab l e as an op tion for the SFC1800A Upconverter. This unit can be
delivered with t he optional Chai n Switching Module in place, or may be purchased separ ately and
installed by the customer (no tools are required). When equipped with thi s module, in the event
of a unit failure (in a 1:1 or 1:N Configuration where N is less than or eq ual to 8), the upconverters
themselves perform the switching. This elimi nates the need for a separate converter protection
switch such as the Radyne RCU101 or RCU108.

2.0 Installation Requirements

The SFC1800A Upconverter is desig ned to be installed within any standard 19 inch eq uipm ent
cabi net or rack, an d requi r es 1 Rack Unit (1RU) mounting space (1.75 inches, 4.44 cm) vertically
and 19 inches (48.26 cm) of depth. Including cabling, a minimum of 20 i nches (50.8 cm ) of rack
dep th is required. The rear panel is has power enter from the left and cab ling en ter from the
center and right as viewed from the rear of the unit. Dat a and con trol cabling can enter from
either side. The unit can be placed on a table or suit able st able surface if requir ed.

Before initially applying power to the unit, it is a good idea to disconnect
the transmit output from the operating station equipment. This is
especially true if the current SFC1800A Upconverter configuration
settings are unknown, where incorrect setting could disrupt existing
comm u nica tions traffi c.

There are no user-serviceable parts or configuration settings located
inside the SFC1800A Upconverter chassis. There is a potential shock
hazard internally at the power supply module. DO NOT open the SFC
Chassis under any circumstances.

The SFC1800A Upconverter contains a Lithium Battery. DANGER OF

EXPLOSION exists if the battery is incorrectly replaced. Replace only

with the same or equivalent type recommended by the manufacturer.
Dispose of used batteries in accordance with local and national
regulations.

3.0 Theory of Operation

The SFC1800A Upconverter has been desig ned to minim i ze the am ount of hardware in the
system, while maximizin g performance . Spurious per formance in t he upconverter is criti cal and
in particular, LO related spur i ous in-band is nonexistent .

The unit is a double conversion microwave upconverter. Th e basic block diagr am is shown in
Figure 3-1.

TM111 – Rev. 1.0 3-1

Theory of Operation SFC1800A Synthesized Frequency Upconverter

3.1 Converter Configuration

The SFC1800A Upconverter has three basic operating configurations. These are: S tand-Alone,
1:1 Sw it ch, and 1:8 S witch.

The upconverter automatically detect s the equipm ent to which it is conn ected, and adjusts its
operat ion accor dingly. S ome user menus, most notably the switch Men u, are only avail able if the
up converter i s connected as the backup unit in a Redundancy Switch System.

The Switch Systems may be referred to as either a Redundancy Switch, a
Protection Switch, or simply a Switch. In addition, in all switch
configurations, the Backup Unit acts as the master (it controls all switch
operations).

3.1.1 Stand-Alon e Opera t io n

If J5 on the Back Pan el of the SFC1800A Upcon vert er (B.U. SWI TCH INTERFACE) is n ot
connected to a Switch, th e unit will automatically configu r e i tself for Stan d-Alone Operati on. The
user can set up all configurabl e param eters using one of t he four differen t In terfaces described in
Section 4.

3.1.2 1:1 Switch

In the case of a 1 :1 Switch System, the upconverter detects to which connector on the switch it is
connected (INTERFACE BACKUP or INTERFACE PRIMARY).

The Primary is also sometimes referred to as the Prime.

If the upconverter is conn ected as the backup, then al l the switch con trols are available to t he
user on that unit.

Figure 3-2 illustrates a typical interconn ection of a SFC1800A Upconverter with an RCU101 1:1
Prot ection Switch.

3-2 TM111 - Rev. 1.0

SFC1800A Synthesized Frequency Upconverter Theory of Operation

3.1.3 1:8 Switch

In a 1:8 Switch, the Converter detects whet her it is con nected as PRIM ARY1 through
PRI M ARY8, or as the BACKUP. The RCU108 is flexible in that it can be set up with anywhere
from 1 through 8 Pri mary SFC 1800A Upconverters. H ow ever, there is only on e backup. Thus,
only one Prime can be backed up at one time.

Figure 3-3 illustrates a typical interconn ection of a SFC1800A Upconverter with an RCU108 1:8
Protection Switch. The configuration shown is a 1:2 Switch.

3.2 Optional Chain Switching Operation

For Ch ain Swit ching, each convert er in a 1:N configurat i on (where N is less than or equal to 8)
will co ntain an op tional C hain Switching Module. Duri ng set up, one of the con verters will be
considered the backup. This is u sually th e converter at t he bot tom of th e r ack. Once the system
is set up and proper l y wi r ed, each con verter t hen has an ID Address and can be programmed
from t he Fron t Panel to set the priority level of each converter in the rack. If no priority is set from
the Front Panel then th e priority will default to level one with the converter cl osest to the back up
having the highest prior i ty and priorities incrementall y decreased the furt her from the back up.

Figure 3-2. RCU10 1 Typ ic al In t er co n nectio n w it h S FC 1 800A Upco nverter

TM111 – Rev. 1.0 3-3

Theory of Operation SFC1800A Synthesized Frequency Upconverter

After al l of the converters have been programmed, th e back up co nverter is then set into a “Learn
Mode. ” The backup poles each converter on a continuous basis, and learns then stores the
setting s of each con verter. Because the swi tch m odules are on a common pr otection bus, each
converter knows the address (position in th e r ack), and the faul t status of all of the converter s in
the r ack. In the event of multiple fail ures, the highest priorit y co nvert er that fails is backed up fir st.

The chain switch provides the primary through path between the converter RF output and the
output of the switch module without bei ng powered . It i s provided with redundant power from all
converters co nnected in the chai n. In the event that a Upconvert er needs to be replaced, th e
Chain Switching Module ca n be removed from the back of t he converter and left in place with out
breaking the interconnecti ons to adj acent converters in t he ch ai n.

Refer to Figure 3-4 for Chain Switching Operation in a 1:1 configuration, and Figure 3-5 for a 1:N
configuration.

Auto-Nonrevertive: A Prime C onverter will be backed

up if it fails. It will remain backed up until it is manually
unbacked.

Auto-Revertive: A P r i me Con verter will be backed up i f

it fails. If a second Converter, which has been deemed
higher prior i ty (see Monitor Backup S tate below) fails,
the switch will unback the first and backup the second
Converter. If the first Con verter recovers after it has
been backed up (i.e., no l onger has a fault) , and a
second Con verter fails, the recovered unit will be put
back on line and the new faulted unit will be backed up.

FORCE BACKUP <SELECT PRIME >: {PRIME 1 - 8, UNBACK}

When i n Manual Backup Mode, this selection will force

the selected Prime to be backed up. Unback will release
any Prime that is currently backed up.

Figure 4-2. Typical Reference Aging vs. Time

Long-term stability of the reference is affected b y factors
other than temper ature. Over days and months, the
frequ ency of t he reference will dr ift at a rate specified as
aging. Typical aging rates of 1 to 5 parts in 10

-10

per day
are typi cal in a crystal that has been stabilized for a fe w
weeks. The first m onth of oper ation for any crystal is a
time where drift due to agi ng can be excessive.
The typical aging curve provides insight into the
exponential decay in aging rate for a 10 M Hz Reference.
Converters shipped from the factory have had their
reference oscillat or aged for a minim um of 30 days and
in addit ion, the aging rate has been verified in the final
week to w ithi n tolerance. H ow ever, converter s that have
been i n storag e or power ed off for a period of several
weeks will exhibit a phenomenon whereby the aging
curve return to the slope shown for zero days of aging.
This aging reset in not well understood but the
manufactu r er s of crystals b el ieve it to b e r el ated t o a
gradual relaxation of th e molecular m akeup of the quart z
substrates and the conductive films deposited on the
quartz.

The rule of thumb when checking the frequency
accuracy of the converter is to make sure that the crystal
has stabilized before att empting any adjustment. For
un i ts that have been in stor age or shipment for more
than a week, allow several d ays of operation before
verif ying the accuracy. F or this r eason, converters
shi pped from Radyne are typically po we r ed-up until the
final day before shipm ent. In addition, the accuracy an d
aging rat e ar e verified immedi ately prior to shipmen t.

4.4 Remote Port User Interfaces

The SFC1800A Upconverter Operato r Serial P or t all ows a remote operator to control the
converter. Throug h the ser i al protocols (A SCII and RLLP) described below, t he rem ote operator
can control gain, frequency, calibration, statu s, and fault isolation. The connector on the rear
panel labeled J8, OPERATOR SERIAL I/O (DB-9 Female) i s the physical port used for these
protocols. It can be configu r ed as eith er a RS-232 or an RS-4 85 interface. If RS-232 is selected,
an ad aptor is need ed between the converter conn ector J8 and the r emote co ntroller. See Secti on

5.9 for detailed pinout information. The port is factory-set to communicate as the DCE (Data

Communication s Equipment) with th e fol l owing setti ngs:

9600 ba u d
8 data bit s
1 start bit
1 stop bit
no p ar i ty

The serial protocol is designed to provide DTE-to-DCE Point-to-Point Comm unications. The
converter is wired as the DCE to provide an interface to a dumb terminal ( D TE) without a null
modem connecti on. Because the serial protocol uses u nique addressable commands, the
converters are cap able of providing multipoint com m unication s between a n umber of converters
and a customer-supplied serial interface. Th e typical mul tipoint communications configurations
include full-a nd ha l f -duplex RS-485. In additi on, a multipoint RS-232 in terface is also possible.

The theory of operation for mult i point requir es that the M& C Computer Transmit Port be
connected in paral lel to all of the R eceive Data Ports of the various con verters. Likewise, the
tran smit ports of t he various conve r ters must all be connected in parallel and tied to the Receive
Data P or t of the M &C Computer. To prevent any one Converter Transmit Port from acti ng as a
low impedance, thus hanging the bus, each transmit port of each converter remains in a high
impedance state until asked by the M&C comput er to transmit.

To prevent data col l isions from all the converte r s responding at once, each con verter must be
software configured for ‘echo off’ in the Configuration Menu. If the converters are being linked to
a dumb terminal, the echo should be turned on local ly.

4.4.1 ASCII Seria l Prot oc ol

The ASCII serial pr otocol serves as a ‘wrapper’ for the M&C dat a.

4.4.1.1 ASCII Command Structure

This se r i al command struct ure uses an AS CII character str i ng format that enables serial control
thr ough the use of a ‘dumb t er minal.’ To different iate a proper command stri ng from noise, all
serial comman ds have a header followed by the specific command characters, followed by
numeric values where required, and are t er min ated by a character r eturn <cr>. The basic
command structure is as follows:

@{Unit Address/}{Command}{Numerical Value(s)}<cr>

For the following examples, a unit address of 0 1 i s assumed.

4.4.2 RLLP Serial Protocol

The Radyne Link L evel Protocol (RLLP) is an alternative serial protoco l used i n conjunction with
the r emote port.

4.4.2.1 RLLP Protocol Structure

When new features are added to Radyne equipment, the control parameters
are appended to the end of the Non-Volatile Section of the Remote
Communications Specification, and status of the features, if any, are added
at the end of the Volatile Section. If a remote M&C queries two pieces of
Radyne equipment with different revision software, they could respond
with two different sized packets. The remote M&C MUST make use of the
non-volatil e count val ue to index to the start of the Vola tile Section . If the
remote M&C is not aware of the newly added features to the product, it
should disregard the parameters at the end of the Non-Volatile Section and
index to the start of the Volatil e Se ction.

Before creating any software based on the information contained in this
document, contact the Radyne Customer Service Department (602-437-

9620) to find out if the software revision for that piece of equipment is
current and that no new features have been added since the release of this
document.

The Com muni cation s Specifi cation ( COMMSPEC) defines the in teracti on of com puter resident
Monitor and Cont r ol software used in satel l ite earth station equipment such as modems,
redundancy switches, multiplexers, and other ancillary support gear. Communication is bi­directional, and is normally established on one or more full-duplex multi-drop control buses that
conform to EIA Standard RS -485.

Each piece of ear th station equipment on a contr ol bus has a unique physical address, which i s
assigned during st ation setup/configuration or prior to shipment. Valid decimal addresses on one
control bus rang e from 032 - 255 for a total of up to 224 devices per bus. Add r ess 255 of each
control bus is usually reserved fo r the M&C comp uter.

data byte is conveyed as mark/space information with two marks comprising the stop data. W hen
the last b yte of data is tran smitt ed, a hold comp r i ses one steady mark (the last stop bit ) . To begin
or resu me data tran sfer, a space substitutes t his mark. This h andlin g scheme is controlled by the

<...DATA..> - The Data field contains the binary, data bytes associated with the
<OP C ODE>. The number of data bytes in th is field is indicated by the <BYTE COUNT> value.

<CHECKSUM> - The checksum is the modul o 256 sum of al l preceding message bytes,
excluding the <SYN > character. The checksum determines the presen ce or absence of erro r s
within the message. In a message block with the following parameters, the checksum is
computed as shown below in Table 4-4.

Table 4-4. Checksum Calculation Example

BYTE FIELD DATA CONTENT RUNNING CHECKSUM

<BYTE COUNT> (B yte 1) 00h = 000000 00 b 00000000b
<BYTE COUNT> (B yte 2) 02h = 00000010b 00000010b

<SOURCEID> F0h = 11110 000b 11110010b

<DESTINATION ID> 2Ah = 00101010b 00011100b

<FSN> 09h = 00001001 b 00100101b
<OPCODE> (Byte 1) 00h = 00 00 00 00 b 00101000b
<OPCODE> (Byte 2) 03h = 00 00 00 11 b 00101000b

<DATA> (Byte 1) DFh = 11011111b 00000111b
<DATA> (Byte 2) FEh = 11111 11 0b 00000101b

Thus, the checksum is 00000101b; which is 05h or 5 decimal. Alternative methods of
calculating th e checksum for the same message frame are:

00h + 02h + F0h + 2Ah + 09h + 00h + 03h + DFh + FEh = 305h.
Since the only concern is the modulo 256 (modulo 100h) equivalent (values that can be
represe nted by a single 8-bit byt e) , th e checksum is 05h.

For a decimal checksum ca lculation, t he equivalent val ues for each informat ion fi eld are:

0 + 2 + 240 + 42 + 9 + 0 + 3 + 22 3 + 25 4 = 77 3;

773 /256 = 3 with a rem ai nder of 5. This remainder is t he checksum for the frame.

5 (decimal) = 05h = 0101b = <CHECKSUM>

4.4.2.3 Frame Descr ipti on an d Bu s Hand sh ak ing

In a M onitor and Control environment, every message frame on a control bus port executes as a
packet in a loop beginnin g with a wait-for-SYN-char acter mode. Th e r emain i ng message format
head er i nformation is then loaded, either by the M&C computer or by a subordinate piece of
equ i pment requesting access to the bus. Data is processe d in accor dance with the OPCODE,
and the checksum for t he frame i s calculated. If t he anticipated checksum does not match then
the wait-for-SYN m ode goes back i nto effect . If the OPCO DE r esides within a comm and
message, it defines the class of act ion that d enotes an i nstru ction that is specific to the device
type, and i s a prefix to the DATA field i f data is r equired. I f the OPC ODE resides within a query
message p acket, then it defines the qu er y co de, an d can serve as a prefix to query code DATA .

4-22 TM111 - Rev. 1.0

SFC1800A Synthesized Frequency Upconverter User Interfaces

The Frame Sequence Number (F SN) is i ncluded in ever y message packe t, an d increments
sequent i ally. When the M & C com puter or bus-linked equipment initiates a message, it assigns
the FSN as a tag for error contr ol and handshaking. A different FSN is produced for each new
message from the FS N or iginator to a specific device on the con trol bus. If a comm and packet is
sent and n ot received at its i ntended destinat i on, th en an appropriate respon se message is not
received by the packet or igin ator. The or i ginal command packet is then re-transmitted with the
same FSN. If t he repeated message is r eceived correctly at this point, i t is considered a new
message an d i s execut ed and acknowledged as such.

If the comm and packet is received at i ts in tended destination but the response message
(acknowledgment) is lost, th en the message originator (usually the M&C computer ) r e-transmits
the or igin al command packet with the same FSN. The destination device detect s the same FSN
and r ecogn i zes that the message is a duplicate, so the associated commands wit hin the packet
are not executed a seco nd time. Howe ver, the respon se packet is again se nt back t o the source
as an acknowled gment in order to preclu de undesired multiple executions of the same command.

To reiterate, valid equi pment resp onses to a message requ ire the FS N tag in the command
packet. Thi s serves as part of the handshake/acknowled ge routine. If a valid response message
is ab sent, then the command is re-transmitted with the same FSN. For a repeat of the same
command in volving iterat i ve processes (such as increasing or decreasing transmit power level),
the FSN is increm ented after each messag e packet. When the FSN value reach es 255 , it
overfl ows and begins again at zero.

The full handshake/acknowled gment involves a rever sal of source and destin ation ID codes in the
next message frame, followed by a response code in the <OPCODE > fi el d of th e m essage
packet from the equipment under contr ol .

4.4.2.4 Global Response Operational Codes

In acknowledgm ent resp onse packe ts, the operat ional code <OPCODE> field of t he message
packet is se t to 0 b y th e r eceiving devices when the message inten ded for the device is evaluated
as valid. The device that receives the valid message then exchanges the <SOURCE ID> with the
<DESTINATION ID>, sets the <OPCODE> to ze r o i n order to indicat e that a good message was
received, and returns t he packet to the origi nator. This "GOO D MESSAGE" Opcode is one of
nine global resp onses. Global response Opcodes are common respon ses, issued to t he M&C
computer or to another device, that can originate from and ar e interpreted by all Radyne
equ i pment in the same manner . These are summarized as follows all Opcode values are

4.4.2.5 Collisi on Avo idance

When prop er l y impl emented, the physical and logical devices an d ID addressing scheme of the
COMMSPE C n or mally pr ecludes messa ge packet contenti on on th e control bus. The i m portance
of designating unique IDs for each device during station configuration cannot be overemphasized .
One pitfall , which is often overlooked, conce r ns multi-d r op override IDs. All too often, mu l tiple
devices of th e same t ype are assigned in a direct-linked "single-thread" configuration accessibl e
to the M&C computer directly. For example, i f two Converter s with different addresses
DESTINATION IDs ar e l inked to the sa me cont r ol bus at the sam e hierarchical l evel, both will
attempt t o r espon d to the M& C computer when the computer generat es a multi-drop override ID
of 1. If their actual setup par ameters, st atus, or internal timing d iffers, they will both attem pt to
respond to the override simultaneously with different information, or asynchronously in their
respective message packets and response p ackets, causing a colli sion on the serial contr ol bus.

To preclude control bus data content ion, different IDs must always b e assig ned to the equipment.
If two or more devices are confi gured for direct-lin ked op er ation, then the M&C compu ter and all
other devices co nfigured in th e same manner must be progr ammed to inhibit broadcast of t he
cor r e sp o ndi ng m ult i-drop override I D.

The multi-drop override ID is always accepted by devices of the sam e type on a common control

The fo llowing mul ti -drop override IDs are device-type specific, wit h the excepti on of
"BROADCAST". These are summarized in Table 4-6 with ID values expressed in decimal
notation:

Multi-drop overr ide ID 01 can be used interchangeab l y to broad cast a message to a DMD­300 0/4000 modem, a D M D-4500/5000 , a DM D15 m odem, or a DVB3030. Radyne recommends
that the multi-drop overrid e IDs b e issu ed only during system configu r ation as a bus test tool by
experienced programmers, and that they not be included in run-time software. It i s also
advantageou s to consider the use of multiple bus systems where war ranted b y a moderate t o
large equipment complement.

Therefore, if a DMD15 Modulator i s queried for its equipment type identifier, it will return a "20"
and D M D15 Demodulator will return a "21" . A DM D15 Mod em will also r eturn an "22". A
DVB3030 Vi deo Modulator will return a “23.”

4.4.2.6 Soft war e Co mpa tibi lity

The COMMSPEC, operating in conjunction within the RLLP shell, provides for full forward and
backward software comp atibi l ity independ ent of the softwar e version in use. New features ar e
app ended to the end of the DA TA fi el d without O PCODE changes. Older software simply
discards the dat a as extraneous in formation wit hout functi onal impairment for b ackward
compatibility.

TM111 – Rev. 1.0 4-25

User Interfaces SFC1800A Synthesized Frequency Upconverter

If new device-resid ent or M&C software receives a message related t o an old software
version, new information and processes ar e not d amaged or affected b y the om ission of d ata.

The implementation of forward and backward software compatibility often, but not always,
requires the addition of new Opcodes. Each new functi on requires a new Opcode assignment if
forwar d and backward compati bilit y ca nnot be attained by other means.

When Radyne equipm ent is qu er ied for bulk information (Query Mod, Query Demod , etc.) it
responds b y sending back two blocks of data; a Non-Vol atil e Secti on (parameters that can be
modified by the user ) and a Volatile Secti on (st atus in formation). It also returns a count value th at
indicates the size of the Non-Volati l e Secti on. Thi s count is used by M&C developers to index
into the star t of the Volatile Sect ion.

When new features are added to Radyne equipment, the control parameters ar e appended to the
end of the Non-Volati l e Secti on, and stat us of the feat ures, if any, ar e added at the end of the
Volat ile Section. If a remote M&C queries two piece s of Radyne equipment with d i fferent revision
software, they may respond with t wo differ ent si zed p ackets. The remot e M &C MUS T make use
of the non-volatile count value to index to the start of the Volat i le Sect ion. If the remote M&C is
not aware of the newly added features to th e Radyne product, it should disregard the parameters
at the end of the Non-Volatile Section and index to the start of the Volatile Section .

If packets ar e handled in this fashion, there will al so b e backward -compatibility between Radyne
equ i pment and M&C system s. Remote M &C systems need not be modified every time a featur e
is ad ded unless th e user needs access to that featur e.

4.4.2.7 RLLP Summary

The RLLP is a simple send-and-wait pr otocol that automatically re-transmits a packet
when an error is detected, or wh en an acknowledgment (response) packet is absent.

Duri ng transmission, the prot ocol wrapp er surround s the act ual data to form information p ackets.
Each tran smitted packe t is subj ect to time out and fram e sequ ence control parameters, after
which the packet sender wait s for the receiver to convey its response. Once a r eceiver ver ifies
that a packet sent to it is in the corr ect sequence rel ative t o the previou sly received packet, it
computes a local checksum on all informat ion within t he packet excluding the <SYN> charact er
and the <CHE C KSUM> fields. If this checksum matches the packet < CHECKSUM>, th e r eceiver
processes t he packet and r espon ds to the packet sender with a valid resp onse (acknowledgment)
packet.

The response packet i s ther efore either an ackno wledgment that the m essage was received
correctly. If the sender r eceives a va lid acknowledgment (response ) packet from t he r eceiver , th e
<FSN> increments and the next packet is transm i tted as required by the sender.

If an acknowl edgment (response) packet is lost, corrupt ed, or not issued due to an erro r and is
ther eby not r eturned to the sender , th e sender re-tr ansmits the original in formation packet; but
with the same <FSN>. When the intended receiver detects a dupli cate packet, the packet is
acknowledged with a resp onse packet and internally discarded to p r eclude undesired repetitive
executions. If the M&C com puter se nds a command packet and the co r r espon ding response
packet is lost due to a system or in ternal er r or , th e computer times out and re-transmits the same
command packet with the same <FS N> to the sa me receiver and waits once again for an
acknowledgment.

identity of t he manager and the security level used in the request.

A view is a group of MIB variables on the agent. The ag ent defines a view for each user based
on the user ident i ty (secu r ityName) and se curity level. F ol lowing are t he major views:

Sy st em view: Access to system description

MIB-II view: Access to the standard MIB-II informat i on

Device view: Access to the device pr ivate information

World view: Access to every manag ed object in the MIB

Following are the a vailabl e access groups:

4.6.4 Management Information Base Structure

This section defines the terminology and hi er ar chy associat ed with management information base
structure at Radyne.

4.6.4.1 Simple Network Management Protocol (SNMP)

Simple Netwo r k Manag ement Prot ocol (SNM P), as its name su ggests, is a relatively simple
prot ocol by which m anagement informat i on for a network d evice m ay be inspect ed and/ or altered
by rem ote administrator s.

4.6.4.2 The Management Information Base (MIB)

Managemen t objects are defined in the Management Information Base ( M IB), which uses a
hierarchical naming scheme. In this scheme, an Object Identifier (OID) identifies each object.
The OI D is a sequence of non-negative integers that uniquely describes the p ath taken th r ough
the hierarchical structure.

MIB objects may then be specified either from the R oot (which has no designator ) , or alternative ly
from anywher e within the hierarchical structure.

For example: 1.3.6.1.4.1.2591.4 is equivalent to {iso(1). org(3). dod(6). internet(1). private(4).
enterprises(1). Radyne(2591). RCS10L(4)} (See Figure 4-4).

In general, we ar e main ly concerned wi th just two groups that resi de in the internet subtree,
namely the mgmt, and private groups. For complet eness however, the four major groups are
discussed below:

4-40 TM111 - Rev. 1.0

SFC1800A Synthesized Frequency Upconverter User Interfaces

Directory {internet 1} 1.3.6.1.1

This area was reserved to describ e how the OSI di r ectory str ucture m ay be used in the Internet.
To date t his has not been implemented and therefore is of little interest to us.

Mgmt {internet 2} 1.3.6.1.2

This area was reserved to describ e objects in the standard MIB. As RFCs defining new groups
are ratified, the Inter net Assigned Numbers Authority (IAN A) assi gns new group IDs.

Experimental {internet 3} 1.3.6.1.3

This subtree provides an area where experimentation i s carried out. Only those organizations
directly involved in the experiment have any interest i n this subtree.

Private {internet 4} 1.3.6.1.4

This is possibly the most import ant area of t he MIB, since it is within this sub tree that vendors
place object s specific to their partic ular d evices. B eneath the private branch, there is a subtr ee
called enterprises, beneath wh ich each vend or may define its own stru ctur e. Vendors are
assigned Private Enterprise Numbers (PENs) that uniquely identify them. They may then place
all obj ects specific to th eir devices in this tr ee, provided of course that the object conforms to the

When new features are added to Radyne, Inc. equipment, the control
parameters are appended to the end of the Non-Volatile Section of the
Remote Communications Specification, and status of the features, if any,
are added at the end of the Volatile Section. If a remote M&C queries two
pieces of Radyne, Inc. equipment with different revision software, they
could respond with two different sized packets. The remote M&C MUST
make use of the non-volatile count value to index to the start of the Vol atile
Section. If the remote M&C is not aware of the newly added features to the
product, it should disregard the parameters at the end of the Non-Volatile
Section and index to the start of the Volatile Section.

Before creating any software based on the information contained in this
document, contact the Radyne, Inc. Customer Service Department (602­437-9620) to find out if the s oftware revis ion for that piece o f equipment is
current and that no new features have been added since the release of this
