Quad Drop & Insert

QDI= 73 bytes Command or Query.

Quad Drop & Insert Commands (E1 CCS Only) QDI=pccddddddddddddddddddddddddddddddddCCssssssssssssssssssssssssssssssssmrrr, where:

p = Port number 1 thru 4 cc = Number of Drop Channels, 0-32. Used to decide Port p’s TX Tributary Rate if Interface Type is Quad Drop & Insert (TFM=8). d = 32 bytes defining Timeslot locations (or channels) CC = Number of Insert Channels, 0-32. Used to decide Port p’s RX Tributary Rate if Interface Type is Quad Drop & Insert (RFM=8). s = 32 bytes defining Timeslot locations (or channels)

Timeslot definition:

0 = Unused 1-9 for timeslots 1–9, A=10, B=11, C=12, D=13…V=31

z=timeslot zero m = E1 Clock Sync/Async mode (Read/Write on Port 1 string, Read-Only on other Ports strings). This is NOT a per port setting, but a global setting. 0=E1's are asynchronous, 1=E1's are synchronous. r = reserved (set to value 0)

Example 1:

131123456789ABCDEFGHIJKLMNOPQRSTUV031123456789ABCDEFGHIJKLMNOPQRSTUV00000 Port 1’s Drop channels 1–31 using timeslots 1–31. Same for Insert. E1 clock mode is synchronous (ReadWrite using Port 1 string).

Example 2:

30412340000000000000000000000000000204123400000000000000000000000000002001000 Port 3’s Drop channels 1–4 using timeslots 1–4. Same for Insert. E1 clock mode is asynchronous (Readonly parameter in Port 3 string).

Note: This command is a bit forgiving in the sense that the modem accepts the command even though the interface type is other than Quad Drop & Insert. This is intentional for use with the CRS-300 switch for 1:N redundancy.

QDI= QDI? QDI* QDI#

QDI?p QDI?pn (where n = 0 to 9 returns the QDI portion of 1 of 10 stored configurations for a single port p)

QDI=pccddddddddd dddddddddddddddd dddddddCCssssssss ssssssssssssssssss ssssssmrrr

(Returns current Quad D&I configuration of a single port p)

1.1 Overview

The CDM-625 Advanced Satellite Modem (Figure 1-1) is intended for both closed network and legacy Intelsat applications. The CDM-625 is a replacement for the CDM-600 and CDM-600L Open Network Satellite Modems, and it includes many new or enhanced features:

• It is compact – 1RU high and 17.6 inches deep – and consumes only 48 watts (typical).

• It features front panel LED Indicators, a keypad, and a Vacuum Fluorescent Display (VFD)

for local configuration and monitoring and control (M&C). It also can be fully remotecontrolled through its serial remote control or Ethernet-based Web Server (HTTP) and Telnet Command Line interfaces.

• It provides a full range of built-in (i.e., no plug-in cards required) traffic data interface

types, including all G.703 types, Quad E1 Drop and Insert, HSSI, and ASI.

• Its IF frequency range simultaneously covers 50-180 MHz and 950-2000 MHz.

• It offers variable data rates, from 18 kbps to 25 Mbps, in BPSK, QPSK, Offset QPSK

(OQPSK), 8PSK, 8-QAM and 16-QAM modes. Viterbi, Sequential, concatenated ReedSolomon (RS), Trellis Coded Modulation (TCM), Turbo Product Coding (TPC), Low-density Parity Check Coding (LDPC), and VersaFEC as Forward Error Correction (FEC) options.

• It is compliant with IESS-308/309/310/315 specifications, but also adds other significant

features in closed network modes.

• Its demod design incorporates fast acquisition, improved composite power handling,

and an integrated adaptive equalizer.

CDM-625 Advanced Satellite Modem Revision 13 Introduction MN-CDM625

• It includes VersaFEC Adaptive Coding and Modulation to increase capacity on IP links.

• It can be equipped with a DoubleTalk

Carrier-in-Carrier® option card that can save up to

50% transponder bandwidth.

• It can be equipped with an optional IP Packet Processor card that, in addition to providing

Layer 3 functionality, incorporates a number of key features for Wide Area Network (WAN) bandwidth optimization: very low overhead Streamline Encapsulation (SLE), Header and Payload Compression, Advanced Quality of Service (QoS), and Advanced Encryption Standard (AES) Encryption.

• IEEE-1588v2 Precision Timing Protocol (PTP) and Jumbo Frame Support are available

options (either requires the CDM-625 Rev 2 Hardware configuration).

• Carrier ID is a patent pending carrier identification (CID) technique that uses MetaCarrier®

spread spectrum technology to embed a unique carrier identification sequence for the transmitted carrier.

1.2 Functional Description

The CDM-625 has two fundamentally different types of interface - IF and data:

• The IF interface provides a bidirectional link with the satellite via the uplink and

downlink equipment.

• The data interface is a bidirectional path that connects with the customer’s equipment

(assumed to be the DTE) and the modem (assumed to be the DCE).

Transmit data is received by the terrestrial interface where line receivers convert the clock and data signals to CMOS levels for further processing. A small FIFO follows the terrestrial interface to facilitate the various clocking and framing options. If framing is enabled, the transmit clock and data output from the FIFO pass through the framer, where the overhead data (IDR, IBS, D&I or EDMAC) is added to the main data; otherwise, the clock and data are passed directly to the Forward Error Correction encoder.

In the FEC encoder, the data is differentially encoded, scrambled, and then convolutionally or block encoded. Following the encoder, the data is fed to the transmit digital filters, which perform spectral shaping on the data signals. The resultant I and Q signals are then fed to the BPSK, QPSK/OQPSK, 8PSK, 8-QAM, or 16-QAM modulator.

The carrier is generated by a frequency synthesizer, and the I and Q signals directly modulate this carrier. For L-Band applications, the directly modulated signal comprises the main output. For IF applications (50–180 MHz), the L-Band signal is mixed down and filtered to produce the desired output. The Rx-IF signal at L-Band is processed by a dual IF superheterodyne receiver.

1–2

Page 43

CDM-625 Advanced Satellite Modem Revision 13 Introduction MN-CDM625

For IF applications (50–180 MHz), the signal is first mixed up to the first IF frequency. The second conversion is a complex mix, resulting in the signal once more being split into an inphase (I) and a quadrature (Q) component, producing an output at near-zero frequency. An AGC circuit maintains the desired signal level constant over a broad range. Following this, the I and Q signals are sampled by high-speed (flash) A/D converters. All processing beyond this conversion is purely digital, performing the functions of Nyquist filtering, carrier recovery, and symbol timing recovery. The resultant demodulated signal is fed, in soft decision form, to the selected FEC decoder, which can be Viterbi, Sequential, TCM, Reed-Solomon, TPC, LDPC or VersaFEC (if installed).

After decoding, the recovered clock and data pass to the de-framer (if IBS, IDR, D&I or EDMAC framing is enabled), where the overhead information is removed. Following this, the data passes to the Plesiochronous/Doppler buffer, which has a programmable size, or may be bypassed. From here, the receive clock and data signals are routed to the terrestrial interface, and are passed to the externally connected DTE equipment.

1.3 Features

1.3.1 Physical Description

The CDM-625 is constructed as a 1RU-high rack-mounting chassis, which can be free-standing if desired. Handles at the front ease placement into and removal from a rack.

The CDM-625 modem chassis assembly (CEFD P/N PL/12587-1 Standard AC Chassis or CEFD P/N PL/12587-2 Optional DC Chassis) is physically comprised of two main card assemblies:

• Baseband Framing Card (CEFD P/N PL/11963-1). This first card includes all of the

interface circuits, the framer/de-framer, plesiochronous/Doppler buffer, Reed Solomon outer codec, HDLC framer, Ethernet switch, and the main microcontroller.

• Modem Card (CEFD P/N PL/12575-1). This second card is the modem itself. It performs

all signal processing functions of modulation, demodulation, and primary Forward Error Correction.

1.3.2 Modem Compatibility

The CDM-625 is fully backwards-compatible with the Comtech EF Data CDM-500, CDM-550, and CDM-550T modems. As an Open Network Modem, the CDM-625 is fully compatible with modems from other manufacturers that are compliant with the IESS-308/309/310/314 specifications. Note, however, that IESS-315 (VSAT Turbo) defines closed network operation, and this therefore requires modems from the same manufacturer at both ends of the link.

The unit is also fully backwards-compatible with the CDM-600 and CDM-600L modems (with the exception of a lower data rate range of 18 kbps). The modem includes software emulation of CDM-600 and CDM-600L.

1.3.4 Verification

The CDM-625 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 you to perform a quick diagnostic test without having to disturb external cabling. During the loopback, all of the receive configuration parameters are temporarily changed to match those of the transmit side, and an internal RF switch connects the modulator output to the demodulator input. When normal operation is again selected, all of the previous values are restored.

1.3.5 Updating Modem Firmware

Chapter 4. UPDATING FIRMWARE

The CDM-625 stores its firmware internally in flash memory, which simplifies the firmware updating process without having to open the modem. Firmware downloads are available via the

1.3.8 Fully Accessible System Topology (FAST)

Appendix C. FAST Activation Procedure

The CDM-625 Advanced Satellite Modem incorporates a number of optional features. In order to permit a lower initial cost, you may purchase the unit enabled with only the desired features.

If you wish to upgrade the functionality of a unit at a later date, Comtech EF Data provides Fully Accessible System Topology (FAST), which permits the purchase and activation of options through special authorization codes. You may purchase these unique, register-specific Fast Access Codes from Comtech EF Data during normal business hours, and then load these codes into the unit using either the front panel keypad or the CDM-625 Web Server (HTTP) Interface. Contact a Comtech EF Data sales representative during normal business hours, or via e-mail to

[email protected], to order the desired options.

FAST System Theory: FAST facilitates on-location upgrade of the operating feature set without removing a unit from the setup. FAST technology allows you to order a unit precisely tailored for the initial application. When your service requirements change, you can upgrade the topology of the unit to meet these requirements within minutes. This accelerated upgrade can be accomplished because of FAST’s extensive use of the programmable logic devices incorporated into Comtech EF Data products.

FAST Implementation: Comtech EF Data’s FAST system is factory-implemented in the modem. All FAST options are available through the basic platform unit at the time of order – FAST allows immediate activation of available options, after confirmation by Comtech EF Data, through the CDM-625 Web Server (HTTP) Interface.

FAST Accessible Options: Hardware options can be ordered and installed either at the factory or in the field (see Table 1-1 for hardware option details). Depending on the current hardware configuration of the unit, you can select options that can be easily activated on-site. The FAST Access Code that is purchased from Comtech EF Data enables configuration of the available hardware.

Table 1-2 shows the FAST and FAST-accessible hardware options available for the CDM-625. The base CDM-625 unit is equipped with Viterbi and Reed-Solomon codecs. It offers BPSK, QPSK, and OQPSK modulation types, and data rates up to 5.0 Mbps, with all interface types. While it is limited to Closed Network operation, it also includes EDMAC and AUPC.

1.3.9 Supporting Hardware and Software

Redundancy Support: Comtech EF Data provides redundant operations support to the CDM-625 as follows:

• For 1:1 redundancy applications, via its low-cost external CRS-170A L-Band and CRS-180

70/140 MHz IF 1:1 Redundancy Switches.

• For M:N redundancy (hub) applications, via its external CRS-300 1:10 Redundancy

Switch or the CRS-500 M:N Redundancy System.

Transceiver Support: The CDM-625 is a companion product for Comtech EF Data’s CSAT-5060 and KST-2000A/B RF Transceivers. The modem incorporates a Frequency Shift-keying (FSK) serial link that can be activated on the Rx-IF port for the purpose of communicating with a transceiver, if connected. In this manner, you may configure, monitor and control the transceiver using either the CDM-625’s front panel display and keypad or any of its remote control interfaces. The EDMAC channel may also be used to convey M&C data to a transceiver at the distant end of a satellite link, if it is connected to a CDM-625.

BUC Support: The CDM-625 incorporates an FSK serial link that can be activated on the Tx-IF port for the purpose of communicating with an FSK-capable “smart” BUC. This link is designed to be compatible with the Global VSAT Forum/ND SatCom specification. In this manner, you may configure, monitor and control the BUC using either the CDM-625’s front panel display and keypad or any of its remote control interfaces.

Additionally, Comtech EF Data provides for an "Advanced FSK" for use with its LPOD BUCs, reusing the existing FSK channel to pass additional "proprietary" commands to expand front panel user control. The EDMAC channel can be used to convey M&C interface to a BUC at the distant end of a satellite link, if it is connected to a CDM-625.

16-QAM: –7 dB to +7 dB (ratio of power spectral density, outbound interferer to desired inbound)

Note: With asymmetric carriers, the absolute power ratio (or CnC ratio) would be different,

depending on the ratio of the symbol rates.

Example:

Outbound interferer = 1 Msymbols/sec

Desired Inbound = 500 ksymbols/sec

Ratio of power spectral density = +7 dB

Within the normal acquisition range of the demod, as follows:

Below 64 ksymbols/sec: ±1 to ± (Rs/2) kHz, where Rs = symbol rate in ksymbols/sec

Between 64 and 389 ksymbols/sec: ± 1up to a maximum of ± 32kHz

Above 389 ksymbols/sec: ±1 to ± (0.1Rs) kHz, up to a maximum of ± 200 kHz
