The Allowable
of the CDM-700 that are supported by the CRS-170A and CRS-180. First, the 1:1 switch is selected depending upon the operating frequency, and then a data interface kit for Slot 1 and Slot 2 is chosen. More information on these kits is provided in the datasheet and manual for CRS-170A or CRS-180 1:1 Redundancy Switches.
1:N Redundancy with the CRS-300: The CRS-300 was originally designed for operation with the CDM-600 and subsequently adapted to a number of other modems. It is capable of supporting interfaces up to the point where there are no more paths left to route traffic. This is the reason why the CRS-300 supports a limited set of the interface combinations supported by the CDM-700.

2.2 Mounting
If the CDM-700 is to be mounted in a rack, ensure that there is adequate clearance for ventilation, particularly at the sides. In rack systems where there is high heat dissipation, forced air-cooling must be provided by top or bottom mounted fans or blowers. Under no circumstance should the highest internal rack temperature be allowed to exceed 50°C (122°F).
The CDM-700 has short rear support brackets mounted to the side of the

3.1 Description
The CDM-700 has two fundamentally different types of interfaces - IF and data.
• The IF interface provides interface with the satellite via the uplink and downlink
equipment and will operate in full duplex or simplex modes.
• The data interface connects with the customer’s equipment (assumed to be the Data
Terminal Equipment [DTE]) and the modem (assumed to be the Data Communications Equipment [DCE]). The data interface is usually full duplex but the modem also operates in simplex Tx only and Rx only applications. (Note – the current version supports duplex and Rx only operation.)
Tx data is accepted by the terrestrial interface where line receivers convert the clock and data signals for further processing. A small First-In-First Out (FIFO) follows the terrestrial interface to facilitate various clocking selections. Th e clock and data are passed to the Framer card, wher e the data from all enabled aligned into a frame structure and sent to the Forward Error Correction (FEC) encoder.
In the FEC encoder, the data is differentially encoded, scrambled, and then encoded.
Following the encoder, the data is fed to the modulator where Tx digital filters perform spectral shaping on the data signals. The resultant in-phase (I) and quadrature (Q) signals are then fed to the remainder of the modulator for QPSK/8-PSK/16-QAM/64-QAM modulation. The carrier is generated by a frequency synthesizer, and the I and Q signals directly modulate this carrier to produce an IF output signal.
The Rx IF signal is digitally IF sampled, converted, demodulated and split into an I and a Q component. An Automatic Gain Control (AGC) circuit maintains the desired signal level constant over a broad range.
Chapter 3. FUNCTIONAL
DESCRIPTION
1
ports on the data interface are combined together in a Multiplexer (Mux) and
1
On all interfaces each port is enabled or disabled. An enabled port operates at the data rate programmed
for that port. A disabled port is not included or zero data rate.
3–1
CDM-700 High Speed Satellite Modem Revision 5 Functional Description MN/CDM700.IOM
After the IF sampling, the processing is all digital, including demodulator, phase lock loops, Nyquist filters and adaptive equalizer. The resultant demodulated signal is fed, in soft decision form, to the selected FEC decoder.
After decoding, the recovered clock and data pass to the Framer card, where the error corrected data stream is Demultiplexed (Demux) and directed to the individual data ports of each data interface. Depending upon the type of data interface, the data passes to the Plesiochronous/ Doppler buffer, which has a programmable size, or alternatively bypasses the buffer. From here, the receive clock and data signals are routed to the terrestrial interface, and are passed to the externally connected DTE equipment.
Physically, the CDM-700 modem comprises several main card assemblies. Refer to Figure 3-1 for a functional block diagram.
• Data Interface: There are two slots at the rear of the modem that where accept the available data interfaces are plugged into the modem. The data interfaces are single port and multi-port type:
♦ A single port interface provides a duplex path. Most are capable of simplex Tx and
Rx operation as well as full duplex operation
♦ A multi-port interface has more than one data interface. For example, the Dual
G.703 (CDI-10) interface has two ports and each Tx/Rx port is independently programmed for E3, T3, or STS-1 operation.
• The Framer card is part of the base modem and includes the Mux/Demux and microcontroller. It also provides the remote and Ethernet ports plus the alarm interface. The keypad and display are also controlled from the framer card.
• FEC: There are two expansion slots for error correction. Currently, one is used. These slots are within the modem and require removal of the cover to access. They look similar to SIM memory modules and are located near the front of the chassis on the Framer card.
• The Modulator card (70/140 MHz or L-Band) is a plug-in board that sits atop the Framer card.
• The Demodulator card (70/140 MHz or L-Band) also plugs into the Framer card.

3.2 Interfaces Modules
The two interface slots and multi-port interfaces provide a simple way to use standard telecom interfaces and to fill the gap in standard data rates between 52 and 155 Mbps by multiplexing data streams together. The standard telecom interfaces are G.703, E3, T3, STS-1 and HSSI at the lower end, and STM-1 or OC-3 at the top end, with a large unserved range between the two ends.
Module Description Mbps
CDI-10 Dual E3 / T3 / STS-1 G.703 Data Interface 34.368 / 44.736 / 55.184 CDI-50-1 OC-3 / STM-1 Single Mode and G.703 Coaxial Interface 155.52 (Fixed) CDI-60 HSSI Interface 1.5 to 70 CDI-70 1000 Base-T Gigabit Ethernet Interface (GbEI) 1.5 to 155.52
Figure 3-1. CDM-700 Modem Block Diagram
Operating with multiple interfaces allows greater efficiency:
• The transponder operates with less backoff and at higher efficiency with a single-carrier
and this translates into higher throughput.
• Operating with a single carrier requires fewer modems than operating with multiple
carriers. The impact of one versus multiple modems in many applications is less of an impact than the monthly transponder expense, but it is part of the overall ease of operation.
For additional information see the applicable section in the manual for each interface.

3.2.1 Data Interfaces And Data Transfer Across The Link
Data into a port (a port is a Tx / Rx pair) at one end of the link is transferred to the same port at the other end. If HSSI is plugged into Slot 1 then a HSSI module is plugged into Slot 1 at the other end of the link for proper data transfer. Transfer of data between the Gigabit Ethernet module in Slot 1at the near end to the HSSI module in Slot 1 at the distant end is not allowed.
When considering 1:N redundancy refer to the CRS-300 manual to see how it is possible to mix some data interfaces within the same switch for a cost effective solution.
3.2.2 Simplex and Asymmetric Operation
The CDM-700 is available in a full duplex or Rx only configuration, and mixing of 70/140 MHz and L-Band in the same chassis is not allowed. Most of the interfaces allow turning off the Tx or Rx side of the data interface, and this configures the disabled port to 0 Mbps. The composite data rate must lie within range of the allowable range for the chosen modulation and code rate.
Asymmetric operation is allowed on most interfaces. The OC-3 / STM-1 is an exception, and it operates only at 155.52 Mbps. Asymmetric operation of the G.703 is also possible, although seldom used. Here is an example of Tx (E3) and Rx (DS3):
CDM-700 At Near End CDM-700 At Distant End
Slot 1 Slot 1
Port 1 Port 2 Port 1 Port 2
Tx Rx Tx Rx Tx Rx Tx Rx E3 Disable Disable DS3 Disable E3 DS3 Disable
Notice the in this example data is transferred across the link to the same port and the same slot.
Asymmetric operation of the Gigabit Ethernet and HSSI interfaces is also allowed and simpler to configure.

4.2 Front Panel
The CDM-700 front panel features a Vacuum Fluorescent Display (VFD), a keypad, eight Light- Emitting Diode (LED) indicators, and a Universal Serial Bus (USB) port. The user enters data via
the keypad, and messages are displayed on the VFD. The LEDs indicate, in a summary fashion, the status of the unit.
Vacuum Fluorescent Display (VFD)
Initially Released Chassis Keypad
The VFD is an active display showing two lines with 24 characters per line. It produces a blue light, the brightness of which can be controlled by the user. It has greatly superior viewing characteristics compared to a Liquid Crystal Display (LCD), and does not suffer problems of viewing angle or contrast.
The keypad for the initially released chassis features six individual keyswitches mounted directly behind a fully sealed membrane overlay. They have a positive‘click’ action that provide the user with tactile feedback.
These six switches are identified as [↑], [↓], [→], [←] arrows, ENT (Enter) and CLR (Clear). The functions of these keys are described in Chapter 6. FRONT PANEL OPERATION.
The keypad for the Rev. A and later chassis features six individual protruding black buttons. They have a positive‘click’ action that provide the user with tactile feedback.The later keypad function is the same as the earlier keypad.
Rev. A and Later Chassis Keypad
LED Indicators
There are eight LEDs on the front panel. The behavior of these LEDs is described in Chapter 6. FRONT PANEL OPERATION.

CLEAR
[CLR]
Left, Right
W X

This key is used to select a displayed function or to execute a modem configuration change.
This key is used to back out of a selection or to cancel a configuration change,
which has not been executed using ENTER [ENT]. Pressing CLEAR [CLR]
generally returns the display to the previous selection.
These arrows are used to move to the next selection or to move the cursor functions. At times, they may also used to move from one section to another.
These arrows are used primarily to change configuration data (numbers). At times, they may also be used to move from one section to another.
The keypad has an auto-repeat feature. If a key is held down for more than 1 second, the key action will repeat, automatically, at the rate of 15 keystrokes per second. This is particularly useful when editing

6.1.3 Front Panel Vacuum Flourescent Display (VFD)
The CDM-700 features a Vacuum Fluorescent Display (VFD). The VFD is an active display
showing two lines of 24 characters each. It produces a blue light, the brightness of which
can be adjusted. Compared to a Liquid Crystal Display (LCD), it has greatly superior viewing characteristics and does not suffer problems of viewing angle or contrast.
As shown above, the ‘welcome screen’ is displayed whenever power is first applied to the unit. The top line identifies the unit model (i.e., CDM-700); the bottom line displays the CDM-700’s installed Firmware Version (version number varies).
Pressing any key navigates to the top-level Select menu. On most menu screens, a flashing, solid­block cursor blinks at a once-per-second rate. This cursor indicates the currently selected item, digit, or field:
CONFIG: Remote Tx Rx Intfc1 Intfc2 Ref Aux
Where this solid block cursor would obscure the item being edited (for example, a numeric field), the cursor will automatically change to an underline cursor:
Tx IF Freq: 0140.0000 MHz (◄ ► ▲ ▼ ENT)
To prevent the display from becoming burnt by a constant image, the unit employs a screen saver feature, which activates after one hour and constantly scrolls and wraps a message across the screen. The top line of the display will show the Circuit ID (which can be entered by the user) and the bottom line will show the circuit Eb/No value (if the demod is locked) followed by ‘Press
any key…’ as shown:
Circuit ID: ------------- not locked. Press any key..
Press any key to restore the previously active screen.

Referring to the next menu, the Symbol Rate is the rate transmitted at the Tx IF connector and corresponds to the Composite Data Rate plus overhead (2.5%), and includes the effects of coding and modulation.
Composite Data Rate = ∑ Port-Data Rates, where:
Ports = all enabled ports for Intfc1 and Intfc2 and depends upon the interfaces installed in Slot 1 and Slot 2.
Symbol Rate = 1.025 *Composite Data Rate /(m *CR), where:

Programming of this modem is not the same as conventional modems because the architecture differs. The incorporation of an internal statistical multiplexer/demultiplexer, and the multi-port interfaces makes the configuration more consistent if the user sets the data rate for each port on the interface. The data rate for each port is programmed under the CONFIG: Intfc1 and CONFIG: Intfc2 menus.

IMPORTANT
To avoid the Tx Carrier from being turned Off when the demodulator loses lock for a very short period of time, the demodulator must be unlocked continuously for period of 10 seconds before the Tx carrier is inhibited. This time interval is fixed.
With this feature enabled it will not affect the internal IF Loopback feature. HOWEVER – if an external IF Loopback is attempted (connecting an external cable from the Tx IF output to the Rx IF input),
then this feature will not function (the Tx carrier cannot turn On until
the demodulator is locked, and the demodulator cannot lock because the Tx output is Off). The result is that the demodulator will not lock, and the Tx carrier will not turn On.

1. INFORMATION RE: ALLOWABLE INTERFACE COMBINATIONS/CONFIGURATIONS:
The combination of installed data interfaces in CDM-700 Chassis Slot 1 (Intfc1) and
IMPORTANT
Slot 2 (Intfc2) drive the appearance/selection of the CONFIG: Intfc1 and CONFIG: Intfc2 menus. Refer to Chapter 3.3 Allowable Data Interfaces In Slot 1 and Slot 2
for a table of the available data interface combinations.
2. INFORMATION RE: MENU DOCUMENTATION FOR INTFC1/INTFC2:
The Config: Intfc1 menu content depicted in this section is dependent on the installed data interface. While the Config: Intfc2 menu content is very similar to that of CONFIG: Intfc1, the data interface menus in this manual are presented in an order
that may or may not be representative of the actual configured unit.
Additional data interfaces will be added to this section as they are introduced. If an interface is not recognized, then
UNKNOWN is displayed. In this case, a later version of
firmware may be required to operate with the data interface.
3. INFORMATION RE: AVAILABLE DATA RATE RANGES:
(a) The composite data rate range depends on the FAST option ordered with the CDM-700. The options are arranged in ascending tiers by symbol rate and modulation type along with the corresponding data rate range.
(b) The Data Rate Range Table in the Chapt er 10. SUMMARY OF SPECIFI CATIONS
summarizes the composite data range by tiers. It also shows how the composite data rate is constructed from the individual data ports on the data interface modules.
(c) The data rate of each individual data port depends on the particular CDI-xx data interface installed in the CDM-700. Additional information about the data rate range for each individual port is provided in the menus below and in the chapter for each
data interface module.

If Intfc1 SWOP: Æ Learning is selected:
Intfc1 Learning: Enable Disable (E)
IMPORTANT
Unit power must be cycled whenever Learning mode is enabled or disabled.
Learning is an Ethernet switch function that allows the LAN (user) side of the Gigabit Ethernet port to learn the MAC addresses of the equipment connected to the Gigabit port.
Learning applies only to the LAN (user) side of the port. There is no learning on the WAN (modem) side of the Gigabit Ethernet port.
If enabled, the interface is in LAN-to-WAN learning mode, and the GBEI learns connections based on
source MAC addresses and ingress ports. The hub thinks the remote site network nodes are local to the hub site network and does not send the traffic over the outbound carrier to the remote site.
If disabled, the GBEI passes all packets from the LAN to the WAN.
Select Enable or Disable using the ◄ ► arrow keys. Press
If Intfc1 SWOP: Æ Mode is selected:
ENTER, then cycle the unit power.

Only one per table. Defaults to 1 and can be changed to any valid entry. Will strip all packets going to the Endstation and will add the appropriate tag entry for all packets leaving the Endstation.
If the VLAN of the packet arriving from the WAN or LAN matches the VLAN tag, the packet passes unchanged.
Configuring a VLAN with this attribute will identify the LAN port as a member of the VLAN. The LAN frame will be removed and the packet will go out untagged.
To Edit the VLAN ID of NATIVE VLANs:
