Quantum and Evolution Series Installation and Operating Handbook Chapter 8 Modem Concepts 1.21 Doppler, Plesiochronous Buffering and Clocking There are two terms commonly used when referring to the receive buffering, namely Doppler and Plesiochronous. Receive Doppler buffering is required because the incoming data from Doppler: the satellite is subject to Doppler shift, which occurs in an approximately 24 hour cycle.
Page 213: Transmit Clocking
Quantum and Evolution Series Installation and Operating Handbook 1.21.1 Transmit Clocking There are three transmit clocking modes that are used in the modem. 1.21.1.1 Internal Clock When Internal is selected, the modem, which is always configured to be a DCE (Data Communications Equipment), supplies the clock.

Quantum and Evolution Series Installation and Operating Handbook 1.21.2 Receive Clocking There are four receive clocking modes that are used in the modem. 1.21.2.1 Satellite When Satellite is selected, the modem disables the Rx Doppler buffer and derives a clock from the incoming satellite signal.

Quantum and Evolution Series Installation and Operating Handbook 1.21.2.4 Internal Clock When Internal is selected, the modem’s Rx timing is phase locked to the modem’s internal clock but is run at the Rx data rate frequency. The Rx Doppler buffer is enabled. The clock and data appear on RT (Receive Timing) and RD (Receive Data) respectively.

Quantum and Evolution Series Installation and Operating Handbook 1.22 Framing and Drop/Insert Overview IBS/SMS Framing 1.22.1 IBS/SMS Service Features The Intelsat definition of IBS framing (IESS 309) is intentionally very similar to Eutelsats SMS framing (EESS 501 ‘SMS QPSK/FDMA System Specification’), as they are both designed to allow common equipment to provide for both services.
Page 222 Quantum and Evolution Series Installation and Operating Handbook used for example with external or internal BER testers to provide a continuous measurement of the live BER.

Robbed Bit Signalling (RBS) Robbed bit signalling is a technique used on T1 PCM bearers whereby signalling is conveyed by stealing the signalling bandwidth from the 64kbps timeslot to which it relates.

In effect if two timeslots were dropped from T1-D4 and T1-ESF bearers with RBS support enabled, although the aggregate data rate would be only 128kbps plus 6.7% overhead, the frame and multiframe structure would be as to support N=24 and N=48 respectively (N x 12 for D4, and N x 24 for ESF as D4/ESF have 12/24 frames per multiframe, relative to which RBS is placed).

Quantum and Evolution Series Installation and Operating Handbook The pair of units, connected as shown, may be used as a direct replacement for a single unit, with all connectors and pin assignments remaining the same. A particular advantage of this arrangement is that one unit of the pair may be replaced without interrupting traffic. To enable the parallel operation of all the interfaces, the off-line unit provides no terminating load, enabling the correct impedance to be maintained even when the two modems are connected in parallel.

Adding framing to a Closed Network link would increase the bandwidth, decrease the Carrier/Noise, decrease the displayed E (as it does not compensate for framing) and therefore degrade the BER.

Page 254: Traffic Shaping
Quantum and Evolution Series Installation and Operating Handbook Note that when TCP acceleration is used in both directions then the TCP acknowledgements going in each direction compete with the data in each direction. Since TCP will attempt to completely fill the data pipeline, there is a possibility that there will not be sufficient bandwidth available for the acknowledgements, which could drastically reduce the throughput level (typically in one direction).
Page 255 Quantum and Evolution Series Installation and Operating Handbook 1.32.9.2 Maximum Bandwidth If excess bandwidth becomes available at any point (i.e. one or more streams do not require their allocated bandwidth), or some of the overall bandwidth has not been allocated to any particular stream, then it is not wasted and it can be allocated in a controlled manner between potentially competing streams.
Page 256 Quantum and Evolution Series Installation and Operating Handbook Each address has an associated subnet mask that delimits the particular host subnet from the overall network. For example, if an address is 10.3.0.0 and the mask is 255.255.0.0 then any packet containing the subnet 10.3 will be matched. To match on the whole of an address the mask must be set to 255.255.255.255.
Page 257 Quantum and Evolution Series Installation and Operating Handbook Assume at this point (when Class 0 ideally wants 900 000bps) that the Class 1 data stream is flowing at 350 000bps. Since 350 000bps is less than the CIR of Class 1 then it will get all the bandwidth it needs.

Quantum and Evolution Series Installation and Operating Handbook 1.32.11 Static and Dynamic Routing The modem can be operated as a two-port static router, one port being the terrestrial interface and the other port being the satellite interface. Static routing is useful for small networks that do not require dynamic routing –...
Page 262: Vlan Operation
Quantum and Evolution Series Installation and Operating Handbook The 40 bytes of IP, UDP and RTP headers are typically compressed to between 1 to 3 bytes. Currently the headers of TCP packets will not be compressed. Ethernet header compression is also supported. The 14 bytes of Ethernet frame (the Ethernet CRC is not sent over satellite even when compression is off) are typically reduced to 1 byte.
Page 263: Adaptive Coding And Modulation (Acm)
Quantum and Evolution Series Installation and Operating Handbook • In point-to-multipoint operation, the modem adds VLAN tags intelligently at the Hub and then filters specific streams at each Remote based on those tags, discarding the VLAN tags prior to outputting the packets. The VLAN tags are used over just the satellite portion of the link where there is a return path and VLAN tags are not already present in the data coming into the modems.
Page 264 Quantum and Evolution Series Installation and Operating Handbook ACM can be used on point-to-point IP links. ACM must be on in Tx on the transmitting modem and Rx in the receiving modem. It must be on in both Tx and Rx in both modems if ACM is to be actively used for both outbound and inbound carriers.
Page 265 Quantum and Evolution Series Installation and Operating Handbook duplex links and support for them in vendor equipment is optional, therefore the modem auto-negotiates this capability with the attached equipment. Paradise ACM is intrinsically tied to an IP traffic shaper and TCP accelerator, allowing data grooming to match data priority to the available bandwidth.
Page 266: Dvb-S2 And Smartlink
Quantum and Evolution Series Installation and Operating Handbook 1.33 DVB-S2 and SmartLink The Quantum modem supports SCPC, DVB-S2 and combined SCPC/DVB-S2 operation. The DVB-S2 standard was approved by ETSI (European Telecommunications Standards Institute) in November of 2006. The new standard incorporates the latest technology in order to provide greater spectral efficiency and improved stability, using high-order modulation schemes and more powerful FEC coding.
Page 267 Quantum and Evolution Series Installation and Operating Handbook Processing Paths through Modem (Top Path is SCPC; Lower Path is DVB-S2/SmartLink) If DVB-S2 is required but no SCPC features are required then as well as selecting SmartLink, the Tx or Rx service should be set to Closed network as this does not add any extra framing to that provided by DVB-S2.
Page 268 Quantum and Evolution Series Installation and Operating Handbook If a DVB-S2-only service is required for an interface other than IP then the Closed Network service should be selected, along with the SmartLink FEC option. This will provide a DVB-S2 service with no additional SCPC framing overhead.
Page 269: Paired Carrier
Quantum and Evolution Series Installation and Operating Handbook 1.34 Paired Carrier Paired Carrier can be used to reduce satellite bandwidth requirements by up to 50% by overlapping transmit and receive carriers in the same space segment. It uses ViaSat’s patented PCMA technology. Adaptive self-interference cancellation is used to subtract the unit’s transmitted signal from the composiste received signal, leaving just the desired signal.
Page 270 Quantum and Evolution Series Installation and Operating Handbook Quantum Modem Paired Carrier Processing Paired Carrier can be added to existing systems as well as being incorporated into the design of new systems. The signal cancellation techniques used guarantees at least 25dB (typically 30dB) cancellation of the unwanted signal meaning that the uplink and downlink signals can share the same space segment.
Page 271 Quantum and Evolution Series Installation and Operating Handbook mesh, Single Channel Per Carrier (SCPC) and Demand Assigned Multiple Access (DAMA) voice and data networks. Paired Carrier helps in the case of bandwidth-limited links. However, if a link is instead power limited then its design can be changed to turn it into a bandwidth-limited link and then Paired Carrier can be used to improve the bandwidth utilisation.
Page 272 Quantum and Evolution Series Installation and Operating Handbook Q. Can I remotely control the Paired Carrier function? A. Yes, Paired Carrier can be controlled remotely in the same way as any other modem function via RS232, RS485, web browser or SNMP. Q.

Quantum and Evolution Series Installation and Operating Handbook 1.35 Sat-ABIS Sat-ABIS is an embedded optimiser in the modem for GSM Abis traffic. It is used in symmetric point-to-point links for cellular backhaul, saving up to 50% bandwidth. It combines and optimises Abis traffic on four T1/E1 interfaces (using either CRC4, FAS, ESF or D4 framing) into a single carrier and supports up to 256 Abis voice channels.

Page 275 Quantum and Evolution Series Installation and Operating Handbook Sat-ABIS Web Diagnostics The compressed data is passed over satellite formatted as HDLC packets that run run asynchronously to the T1/E1 interfaces. However, the hub clock input to Sat-Abis is extended over satellite and used to synchronise the remote to the hub. The hub clock is used as a clock generator for HDLC-framed data and the remote modem derives its clock from the satellite signal and generates a 2.048 MHz bearer to the BTS.
