4.2.1.1.6.6 Utility - Modem Type
DISPLAY SELECTIONS/DESCRIPTION
UTILITY MODEM TYPE
MODEM TYPE CUSTOM
REV. EMULATION CURRENT_VERSION
CDM-IP 300L only supports CUSTOM
Programs an emulation mode of a previous Bse modem M&C functional revision. This allows the user to select the CURRENT VERSION or FUNCTIONAL X.
CURRENT_VERSION FUNCTION VERSION X (X = Rev. Emulation desired)
Notes:
1. Programming a current version (default) allows all features and options (if installed) to operate normally.
2. Programming a FUNCTIONAL version (X) eliminates any changes that affect the later version. The revision emulation feature affects only functional changes.
3. A correction change (e.g., VER 3.1.2) remains fixed in accordance with the latest version. Since the revision emulation default is the current version, program the functional version at the start of each operation.
4. The revision emulation feature does not affect some interface changes for the direct operation of the modem (Configuration save/recall, test mode screen in the Utility/System, all factory setup modes, etc.).

1.3.1 AUPC
An important innovation in the CDM-IP is the addition of Automatic Uplink Power Control (AUPC). This feature enables the modem to automatically adjust its output power to maintain the E protection against rain fade, a particularly severe problem with Ku-band links.
To accomplish this, the framed mode of operation must be used, and the distant end modem constantly sends back information about the demodulator Eb/No using reserved bytes in the overhead structure. Using the E power, and hence, a closed-loop feedback system is created over the satellite link.

b/No
, the local modem then adjusts its output

2
CDM-IP 300L IP-Centric Satellite Modem Rev. 1 CD/CDMIP300L.IOM
A benefit of this feature is that whenever framed operation is selected, the remote demodulator’s Eb/No can be viewed from the front panel display of the local modem.
1.3.2 SOFTWARE
The internal software is both powerful and flexible, permitting storage and retrieval of up to 10 different modem configurations. The modem uses ‘flash memory’ technology internally, and new firmware can be uploaded to the unit from an external PC. This simplifies software upgrading, and updates can now be sent via the Internet, E-mail, or on disk. The upgrade can be performed without opening the unit, by simply connecting the modem to the serial port of a computer.
1.3.3 VERIFICATION
The unit 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 the user 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. When normal operation is again selected, all of the previous values are restored.
1.3.4 IGMP SUPPORT FOR MULTICAST
IGMP is a standard feature in the CDM-IP. If enabled, it responds to IGMP queries for the configured multicast routes on the transmit side and generates IGMP queries on the receive side. If there are no active IGMP receivers on the LAN, it will stop forwarding the multicast traffic (received from the satellite) to the LAN.
1.3.5 easyConnectMODE
easyConnect is the new CDM-IP modem intelligent networking solution that allows a link to be setup with minimal configuration (no specific routes need to be configured).
The CDM-IP also supports non-IP traffic with easyConnect. All IP traffic will be subject to user configured QoS restrictions.
1.3.5.1 easyConnectOPERATION
The following is a detailed description of how an easyConnect pair should be setup and configured as well as information about how easyConnect functions.
Because easyConnect is a “smart wire,” the devices that are attached to it on either
side of the satellite should be on the same subnet and should not configure a next hop address to be the CDM-IP (as should be done with router mode). For purposes of configuration, easyConnect mode should be viewed to function in much the same way as a bridge (however, without spanning tree protocol).
3
CDM-IP 300L IP-Centric Satellite Modem Rev. 1 CD/CDMIP300L.IOM
All of the features that groom and optimize the satellite link in router mode are also
available in easyConnect mode.
easyConnect Multicast Option – Multicast packets in easyConnect mode are
identified using multicast MAC address. These identified multicast packets are either routed or dropped based on the easyConnect multicast option.
easyConnect uses MAC (layer 2) addresses to learn where to send packets. In
comparison, router mode uses the destination IP address in the packet in conjunction with the route table to determine where to forward the packets.
The CDM-IP Ethernet interface in easyConnect mode is configured to be in
promiscuous mode with a data rate of 10BaseT Half Duplex. The CDM-IP needs to be in promiscuous mode in order to learn the attached networking devices.
Since easyConnect does not use a routing table, the determination of where to send
a packet is made by a learning process. When the system is powered-up, all packets from each subnet (local and remote) will be sent over the satellite interface. However, as each CDM-IP learns which devices are attached to their local Ethernet interfaces, the CDM-IP begins to filter packets which it has learned are locally attached to its Ethernet interface.
The easyConnect learning/forwarding algorithm is as follows:
If the packet is destined for the CDM-IP, process it locally.
If the packet is from the Ethernet interface, send it to the Satellite interface, unless
the destination layer 2 (MAC address) of the packets matches the source layer 2 address for a packet we have already seen, the destination MAC address of this packet is on our local subnet; so why send it over the satellite interface. In this case, the CDM-IP will drop the packet.
If the packet is from the satellite interface, send it out the Ethernet interface.
easyConnect mode will automatically use Header Compression (even if Header
Compression option has not been purchased). Because of this, some of the initial
IMPORTANT
traffic sent between two devices will not be received over the satellite until a full Header is transmitted. For example, the default Header Compression Refresh Rate is 50 packets. If a ping is sent over the satellite it will time out until the full Header packet is sent. The Header Compression Refresh Rate on the Administration Menu can be reduced to minimize the amount of traffic lost when traffic is first sent between two devices. Once communication between two devices has been established, both CDM-IP modems will be able to receive all traffic, unless one CDM-IP is power cycled or reset.
4
CDM-IP 300L IP-Centric Satellite Modem Rev. 1 CD/CDMIP300L.IOM
Do not enable IF Loopback (or link the TX to RX by a BNC cable or satellite) on a CDM-IP operating in easyConnect when connected to a LAN. In this configuration,
IMPORTANT
easyConnect will resend all layer 2 broadcast packets and cause a “broadcast storm” on the LAN. To perform a loop test to verify the modem or satellite link, do one of the following:
1. Reconfigure the CDM-IP to CDM-300L Emulation Mode by selecting Configuration/Interface and then selecting EIA-422/530, V.35, or EIA-232.
2. Set the CDM-IP to Router Mode.
1.3.6 CDM-IP WORKING MODES AND HDLC ADDRESSING MODES
There are two Working Modes of the CDM-IP available: easyConnect and Router Mode. There are also three HDLC Addressing Modes: Point-to-Point, Small Network, and Large Network. This section will describe the functionality of these modes in order to optimize the CDM-IP modems in your network.
The Working Mode and HDLC Address Mode of the CDM-IP modems must be identical to pass traffic between modems.
IMPORTANT
easyConnect - This is the default Working Mode of the CDM-IP. easyConnect only operates in Point-to-Point Mode, meaning that it is only communicating with one other CDM-IP modem. This mode allows the CDM-IP to be setup with minimal configuration (no specific routes need to be configured). In this mode, the CDM-IP is acting as a “smart wire” over a satellite link between two CDM-IP modems. This allows the CDM-IP to simultaneously forward IP traffic and non-IP traffic, such as IPX.
Changing the Working Mode or HDLC address Mode of the CDM-IP modem requires the CDM-IP module to be rebooted. Before the user can select a different mode, the CDM-IP will notify the user that changing the mode will require a reboot.

This diagram shows a 256 kbps Point-to-Point duplex link in easyConnect Mode. Note that both sides of the link are on the same IP subnet - 10.10.0.0/16. There are no routes or HDLC addresses to configure. When the system is powered-up, all packets from each subnet (local and remote) will be sent over the satellite interface. Each CDM-IP learns which devices are attached to their local Ethernet interfaces and will only send packets over the satellite that are not destined for the locally attached devices.
Router Mode – This mode allows up to 256 static routes to be configured and can operate in Point-to-Point, Small Network and Large Network Mode. Small and Large Network Modes allow for multiple CDM-IP modem communication links. A Small Network is defined as up to 254 separate HDLC addresses and Large is from 255 to 32766 separate HDLC addresses. The reason for the separate HDLC Modes is to allow the user to minimize the HDLC overhead transmitted over the satellite based upon the size of their network. In Point-to-Point, no HDLC address is transmitted; Small Network transmits 1 byte and Large Network transmits 2 bytes as part of HDLC header for each packet. Non-IP traffic is not supported in Router Mode.

Each CDM-IP has a static route defined for the distant CDM-IP subnet. The Next Hop is automatically defined as Point-to-Point and there are no HDLC addresses to configure. All that would be required to send traffic between the PCs on each subnet would be to define the local CDM-IP as the PC default gateway. The CDM-IP modems will only pass traffic over the satellite link by the ToSat routes configured in the Route Table.

Figure 3. Router Mode, Point-to-Multipoint Diagram
“Star Network” Point-to-MultiPoint Configuration - Here, Hub CDM-IP 1 is transmitting a common 2.048 Mbps link to 2 remote CDM-IPs. In turn, Remote CDM-IP 3 is transmitting a 256 kbps link back to Hub CDM-IP 1. Remote CDM-IP 4 is also transmitting a 256 kbps link back to the Hub, but it is a separate link to Hub CDM-IP 2.
Since this is a Point-to-MultiPoint configuration, HDLC addressing is used so that the traffic not intended for a particular destination can be filtered. For unicast traffic, it is best to associate a unique HDLC address for each site in the network. For this case, the Hub Site is HDLC 0x01, Remote A is HDLC 0x02 and Remote B is 0x03. Each CDM-IP modem would select the HDLC address associated with its site as a RX HDLC Address, so both CDM-IP modems at the Hub would have 0x01 as the first RX HDLC Address, CDM-IP 3 would have 0x02 and CDM-IP 4 would have 0x03.
Hub CDM-IP 1 has static routes defined for both remote CDM-IP subnets with the Next Hop HDLC address being the HDLC address associated with the remote site. Both remote CDM-IPs have static routes to the hub with the next Hop being HDLC 0x01. The Hub RX only CDM-IP 2 has a default route (ToEth) to Hub CDM-IP 1 because all outbound traffic will go through CDM-IP 1.
8
CDM-IP 300L IP-Centric Satellite Modem Rev. 1 CD/CDMIP300L.IOM
Additionally, HDLC addresses can be used to select or filter multicast traffic on the hub outbound common carrier. Hub CDM-IP 1 has two multicast routes defined with two Next Hop HDLC addresses, 0x10 and 0x11. Remote CDM-IP 2 has RX HDLC Address 0x10 enabled to receive one of the multicast streams. Remote CDM-IP 3 has RX HDLC Addresses 0x10 and 0x11 enabled to receive both of the multicast streams.
Additonal remote sites can be added through a dedicated RX Only CDM-IP at the hub for each remote.

Figure 4. Router Mode, Partial Mesh, 1½ Hop Diagram
Full or partial “Mesh Network” Configuration – The “Star Network” configuration works for a “hub-centric” network, where all traffic is either coming to, or from, one central hub. There are several ways to send traffic between remote sites.
9
CDM-IP 300L IP-Centric Satellite Modem Rev. 1 CD/CDMIP300L.IOM
The first method does not require any additional CDM-IP modems than is described in Figure 1, Router Mode, Point-to-Multipoint Diagram. Just by adding static routes, traffic could be sent between Remote Site A and B. Remote site A and B would add a static route for remote destination subnet, but since the path to the remotes must go through the Hub, the Next Hop HDLC Address would be 0x01, not the HDLC address of the Remote. Traffic from Remote B would be transmitted to Hub RX Only CDM-IP 2, forwarded to Hub CDM-IP 1 and retransmitted to Remote A. With this method, all traffic must go through a “double hop” in order to arrive at the destination.
To avoid the additional delay of the “double hop” method, an alternative method would require an additional RX Only CDM-IP modem at remote site for every other remote site connection needed. In the Figure above, Router Mode, Partial Mesh, 1½ Hop Diagram, Remote Site B has added a RX Only CDM-IP and a static route to 10.20.0.0/16, Next Hop 0x01 (through the Hub). Remote Site A has added a static route for 10.30.0.0/16, Next Hop 0x03. To establish a connection between Remote A and B, Remote A would reconfigure the TX frequency and data rate to set up a link with the Remote B RX Only modem. The return path still must go from B to the Hub and then to A, but A has a direct link to B, thus this is considered a 1½ hop link.
Additional RX Only or full duplex CDM-IPs can be added at Remotes based upon what 1½ hop link or single hop connections are required. Always use the following guidelines:
1) All CDM-IP modems will list the Site HDLC as their first RX HDLC Address.
2) For Satellite routes, the Next Hop is the destination Site HDLC (unless there is not a direct satellite link, whereas the Next Hop must be the Hub Site).
3) RX Only CDM-IP modems will need a default To Ethernet route to a duplex CDM-IP at the site in order to forward traffic.
Feature Support - The CDM-IP modem also has several standard and optional features that can be used to further optimize security, performance and efficiency. The following table defines how these features are supported in the two different Working Modes:

CDM-IP 300L IP-Centric Satellite Modem Rev. 1 CD/CDMIP300L.IOM
1.4.1 TURBO PRODUCT CODING (TPC)
The optional Turbo Product Coding (TPC) is a recent development in FEC techniques that delivers significant performance improvements when compared to Viterbi with concatenated Reed-Solomon. TPC simultaneously offers increased coding gain, markedly lower decoding delay (leading to improved TCP/IP performance), and bandwidth savings of up to 40%. The TPC option includes two modes (BPSK 22/44 and BPSK 5/16) that permit operation from exceptionally small antennas where flux density issues are of concern.
1.4.2 3XDES ENCRYPTION WITH ABILITY TO CHANGE KEYS
The CDM-IP optionally supports 3xDES-128 encryption and decryption, for the highest level security for link encryption. Each unit supports eight encryption keys and eight decryption keys. The keys are user configurable. Each route can be assigned to be encrypted by any of the eight available keys, random key method, or transmitted in clear.
13
CDM-IP 300L IP-Centric Satellite Modem Rev. 1 CD/CDMIP300L.IOM
1.4.3 IP HEADER COMPRESSION
Header Compression is also an optional feature of the CDM-IP modem. The CDM-IP supports Header Compression for the following Ethernet and Layer 3 & 4 Headers:
Supported Ethernet Headers
Ethernet 2.0
Ethernet 2.0 + VLAN-tag
Ethernet 2.0 + MPLS
802.3-raw
802.3-raw + VLAN-tag
802.3 + 802.2
802.3 + 802.2 + VLAN-tag
802.3 + 802.2 + SNAP
802.3 + 802.2 + SNAP + VLAN-tag
802.3 + 802.2 + SNAP + MPLS
Supported Layer 3&4 Headers
IP
TCP
UDP
RTP (Codec Independent)
Header Compression reduces the required VoIP bandwidth by 60%. Example: A G.729a voice codec, operating at 8 kbps, will occupy 32 kbps once encapsulated into IP framing on a LAN. Using IP/UDP/RTP Header Compression, the same traffic only needs 10.8 kbps total WAN satellite bandwidth to cross the link. A total maximum of 64 simultaneous VoIP calls can be compressed. Normal Web/HTTP traffic can be reduced an additional 10% via IP/TCP header compression.
Header Compression Configuration – Header Compression is completely independent from QoS, and there is no configuration required except enabling the Header Compression feature on both the sending and receiving CDM-IP modem. Packets with a Header Compression supported header will automatically be identified for compression. The only configuration consideration is the Header Compression Refresh Rate. This is how many compressed header packets will be sent before a single full header packet is sent. Some compressed header traffic could be lost during deteriorated satellite link conditions. Sending a full header packet will allow the return of the traffic stream. The Refresh Rate can be increased for poor satellite link conditions or decreased to further reduce overhead.
Header Compression Statistics - These statistics will display the total bytes of the pre­compressed and post-compressed traffic and effective compression ratio.
14
CDM-IP 300L IP-Centric Satellite Modem Rev. 1 CD/CDMIP300L.IOM
1.4.4 QUALITY OF SERVICE
Quality of Service (QoS) is an optional feature of the CDM-IP modem. The user may select one of three modes of QoS operation:
Mode 1 – QoS Rules based on Maximum Bandwidth and Priority
Mode 2 – QoS Rules based on Minimum and Maximum Bandwidth
Mode 3 – DiffServ
QoS Segmentation and Reassembly (SAR)
Packet Segmentation and Reassembly (SAR) is enabled automatically while QoS is enabled. However, SAR is an adaptive process; it will trigger only if the packet latency exceeds the threshold value (default to 20 msec). Latency value is calculated based on the satellite transmission bandwidth. The minimum segment size was limited to 480 bytes excluding satellite HDLC header in order to avoid satellite overhead and consumption of CPU cycles.
1.4.4.1 MAXIMUM BANDWIDTH/PRIORITY MODE
QoS Rules can be assigned to up to 32 different types of flows to be defined by the user. Flows can be defined by any combination of Protocol (FTP, UDP, RTP, etc.), Source/Destination IP (specific or range), and/or Layer 3 Source/Destination Port.
Priority - A Priority level from 1 to 8 is assigned for each flow. The CDM-IP module classifies each packet that is to be forwarded over the satellite. The packet will then have a Priority assigned according to the defined QoS Rules. Any packet that does not meet a QoS Rule is assigned to the Default Rule and will be assigned a Priority of 8. Priority 1 packets will be forwarded immediately, Priority 2 packets will be forwarded as soon as there are no Priority 1 packets in the Queue, and so on. Any latency critical traffic, such as VoIP/RTP should always be assigned Priority 1.
Maximum Bandwidth - This can also be assigned to a flow to restrict the Maximum Bandwidth that any particular flow will utilize, or the default of no bandwidth restriction can be selected.
Filtering - QoS also allows specific flows to be designated as “filtered”, so the CDM-IP will discard traffic that the user does not want to forward over a satellite link.
QoS Rule Hierarchy - It is quite possible to have traffic that meets the definitions of several QoS Rules. All traffic will be classified into the first QoS Rule that is a match, or fall into the Default Rule. The most specific QoS Rule will always be first. For example, a QoS Rule that identified a Source and Destination IP Address would be assigned ahead of a rule that just defined RTP protocol. QoS Rules that have the same amount of variables defined are sorted as follows:
15
CDM-IP 300L IP-Centric Satellite Modem Rev. 1 CD/CDMIP300L.IOM
1. Having a Protocol defined.
Protocol Priority: a. VOCE Voice Real Time Protocol b. VDEO Video Real Time Protocol c. RTPS Real Time Protocol Signalling d. RTP All Real Time Protocol e. PFTP Passive File Transfer Protocol f. HTTP Hypertext Transfer Protocol g. TELN Telnet Protocol h. SMTP Simple Mail Transfer Protocol i. SNMP Simple Network Management Protocol j. SQL Structured Query Language Protocol k. ORCL ORACLE Protocol l. CTRX CITRIX Protocol m. SAP Service Announcement Protocol n. UDP User Datagram Protocol o. TCP Transmission Control Protocol p. IP All Internet Protocol q. N-IP All Non-Internet Protocol
2. Source IP Address or subnet defined.
3. Destination IP Address or subnet defined.
4. Source Port defined (lowest Port number first).
5. Destination Port defined (lowest Port number first).
The CDM-IP modem will sort each QoS rule as they are added and the QoS Configuration display will be updated to reflect the order with which rules are matched.
QoS Statistics - Every QoS Rule defined can be monitored to see the traffic flow for each Queue. These statistics will display the traffic sent in each Queue, the amount of dropped traffic, and the number of Active Flows.
Protocol and Port Number Considerations - When defining QoS Rules, it is important to be aware of specifics of the traffic for which the rule is intended.When selecting a protocol for a QoS Rule, be aware that the CDM-IP allows for a very abroad selection (such as IP) or a very specific protocol. For example, RTP traffic can consist of UDP portion (for voice or video) and a TCP portion (for RTP signaling). These could have separate QoS Rules created or all be included in a single Rule by selecting RTP as the protocol. The following diagram illustrates where each protocol selection resides.

Selection of Source/Destination Ports should only be done if the user is aware of the port usage of the desired protocol or application. There are well known ports for various protocols, but often only the ‘command’ messaging is transacted on these ports and the ‘data’ is transferred through a negotiated port.

IMPORTANT
Once the QoS Rules are defined, each type of traffic flow should be isolated and sent to verify that it is being sent in the intended QoS Rule.
1.4.4.2 MINIMUM/MAXIMUM BANDWIDTH QOS MODE
QoS Rules can be assigned to up to 32 different types of flows to be defined by the user. Flows can be defined by any combination of Protocol (FTP, UDP, RTP, etc.), Source/Destination IP (specific or range), and/or Layer 3 Source/Destination Port.
Maximum Bandwidth - This can be assigned to a flow to restrict the Maximum Bandwidth that any particular flow will utilize, or the default of no bandwidth restriction can be selected.
Minimum Bandwidth - Minimum specification that allows a committed information rate (CIR) to be applied to user defined classes of traffic, or the default of no minimum bandwidth can be selected.
18
CDM-IP 300L IP-Centric Satellite Modem Rev. 1 CD/CDMIP300L.IOM
Weighted Random Early Detection (WRED) – Without Weighted Random Early Detection (WRED), output buffers fill during periods of congestion. When the buffers are full, tail drop occurs; all additional packets are dropped. Since the packets are dropped all at once, global synchronization of TCP hosts can occur as multiple TCP hosts reduce their transmission rates. As the congestion clears, the TCP hosts increase their transmissions rates, resulting in waves of congestion followed by periods where the transmission link is not fully used.
WRED allows for more graceful dropping of packets, as QoS queues get full. In the previous CDM-IP release, a simple tail drop algorithm was applied to packets as they were being added to the QoS queues. This can result in large number of contiguous packets being dropped which causes many protocols such as RTP and TCP to ungracefully degrade performance in a over­consumed or bursty scenario. WRED applies a randomization which means that the percentage change to drop packets increases as the queue becomes full, and minimizes the chances of global synchronization. Thus, WRED allows the transmission line to be used fully at all times.
Filtering – Any specific flow can be designated as filtered (see Maximum Bandwidth/Priority QoS).
QoS Rule Hierarchy – The QoS Rule Hierarchy is the same as Maximum Bandwidth/Priority QoS.
QoS Statistics - QoS Statistics are displayed as Maximum Bandwidth/Priority QoS.
1.4.4.3 DIFFSERV QOS MODE
The CDM-IP QoS can also be set to DiffServ Mode to make it fully compliant to the Differential Services QoS standards.
Class Selector DiffServ Code Points (DSCP) – Some implementations of DiffServ will prioritize traffic by Class Selector assignment. This is defined in the DiffServ Code Points (DSCP) within the IP header. The first 3 bits of the DSCP define the Class Selector Precedence (or Priority):
Class Selector DSCP CDM-IP Priority
Precedence 1 001 000 1 Precedence 2 010 000 2 Precedence 3 011 000 3 Precedence 4 100 000 4 Precedence 5 101 000 5 Precedence 6 110 000 6 Precedence 7 111 000 7
Default 000 000 9
The CDM-IP will prioritize the traffic based upon the DSCP Class Selector Precedence.
NOTE: All traffic that does not have the DSCP Class Selector Precedence defined (000
000) will be placed in the Default Queue and have a Precedence of 9.
19
CDM-IP 300L IP-Centric Satellite Modem Rev. 1 CD/CDMIP300L.IOM
Expedited Forwarding and Assured Forwarding DSCP Another implementation of DiffServ uses all 6 bits of the DSCP to define Expedited and Assured Forwarding:
DiffServ Type
Expedited Forwarding Assured Forwarding – Class 1 Assured Forwarding – Class 2 Assured Forwarding – Class 3 Assured Forwarding – Class 4
Class Selector DSCP
Precedence 1 101 110 1 Precedence 8 001 xx0 8 Precedence 8 010 xx0 8 Precedence 8 011 xx0 8 Precedence 8 100 xx0 8
CDM-IP
Priority
Expedited Forwarding (EF) DSCP – This defines premium service and is
recommended for real time traffic applications such as VoIP and video conferencing.
Assured Forwarding (AF) DSCP – This defines 4 service levels and also uses the last 3 bits of the DSCP to define the Drop Precedence (Low, Medium, or High). The Drop Precedence determines which packets will most likely be dropped during periods of over congestion, similar to Weighted Random Early Detection (WRED). As a result, each of the 4 AF service levels also have 3 Drop Precedence levels for which the CDM-IP provides 12 seperate queues.
Minimum Bandwidth (AF only) - Minimum specification that allows a committed information rate (CIR) to be applied to user defined classes of traffic, or the default of no minimum bandwidth can be selected.
Maximum Bandwidth (AF only) - This can be assigned to a flow to restrict the maximum bandwidth that any particular flow will utilize, or the default of no bandwidth restriction can be selected.
NOTE: Minimum and maximum bandwidth is only configurable for each of the 4 Assured Forwarding classes.
NOTE: Typically, DiffServ is implemented using exclusively Class Selector DSCP or exclusively Expedited and Assured Forwarding DSCP. The CDM-IP is fully DiffServ compliant and will work with either DiffServ implementation or with a combination of both.
1.4.5 PAYLOA D COMPRESSION
Traffic optimization through Payload Compression is another optional feature of the CDM-IP modem.
- Framer II required
- FAST feature to upgrade
- Uses AHA chip
- Compression algorithm applied to all data (HDLC header excluded)
20
CDM-IP 300L IP-Centric Satellite Modem Rev. 1 CD/CDMIP300L.IOM
- Compression statistics are fed back to QoS in order to maximize WAN utilization while maintaining priority, jitter and latency.
- 1024 simultaneous compression sessions to maximize compression across multiple distinct traffic flows.
- Compression algorithm not applied to RTP streams because this traffic is already compressed and would only INCREASE the sat bandwidth if compressed again.
- Additional statistics have been added to the compression statistics menu in order to provide feedback on the compression efficiency that has been achieved.
ADLC vs LZS compression comparison
Note: These numbers have been generated by using an internally created test program. This program takes the target benchmark files and splits the files into payload size chunks and compresses each chunk in a separate invocation of the compression algorithm. This is important to note because most compression algorithms are applied to the entire file data set as a single invocation of the compression algorithm which is easier for other types of compression algorithms (LZS, GZIP in specific). This, of course, does not apply to streamed packet data across an IP network (ftp transfer, for example).

4 Front Panel Menus

4.1 FRONT PANEL OPERATION
The user can control and monitor the base modem operation of the CDM-IP 300L from the front panel, using the keypad and display. Only the IP module Ethernet IP Address and IP Subnet can be viewed or changed from the front panel. Nested menus are used, which display all available options, and prompt the user to carry out a required action.
The display has two lines each of 16 characters. On most menu screens, the user will observe a flashing solid block cursor, which blinks at a once-per-second rate. This indicates the currently selected item, digit, or field. 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.
If the user were to display the same screen for weeks at a time, the display could become ‘burnt’ with this image. To prevent this, the unit has a ‘screen saver’ feature, which will activate after 1 hour. 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....’. The message moves from right to left across
the screen, then wraps around. Pressing any key will restore the previous screen.
