Turbo Product Coding

The optional Turbo Product Codec delivers significant performance improvement when compared to Viterbi with concatenated Reed-

Solomon. It offers increased coding gain, lower decoding delay, and significant bandwidth savings compared to traditional FEC.

EDMAC & AUPC Operation

The CDM-570/L-IP has the ability to monitor and control the distant end of a point-to-point satellite link using EDMAC or EDMAC2. User data is framed and bits are added to pass control, status, and AUPC information. This is transparent to the user.

Management

The modems support SNMP, web-based and command line interfaces for management. The modems can also be configured and monitored from the front panel, or through the remote M&C port (for non-IP mode of operation). Ten complete RF configurations may be stored in the modem. An event log stores alarm and status information in non-volatile RAM, while the link statistics log stores link performance (Eb/No and AUPC performance) for monitoring and reporting purposes.

G.703 Clock Extension

Mobile networks require precise synchronization of base stations, which is a challenge when using IP backhaul. Most operators are forced to use GPS-based external equipment for site synchronization. CDM-570/L-IP offers a G.703 clock extension option that propagates a high stability reference from hub to the remote. This process does not require additional bandwidth.

FAST Feature Enhancements

The FAST codes make it easy to upgrade the modem capability in the field. New features can be added on site, using FAST access codes purchased from Comtech EF Data that can be entered via the front panel.

IP Module

With its innovative architecture and support for advanced capabilities, IP Module-equipped versions of the CDM-570/L allow for efficient

IP networking and transport over satellite. The CDM-570/L-IP supports a wide range of applications and network topologies.

Header Compression Option

Configurable on a per route basis, header compression reduces the bandwidth required for VoIP by as much as 60%. Example: A

G.729 voice codec, operating at 8 kbps, requires 32 kbps bandwidth once encapsulated into an IP/UDP/RTP frame. With compression, the same voice call needs only 10.8 kbps total WAN satellite bandwidth. Typical Web/HTTP traffic can also be reduced by 10% via

IP/TCP header compression.

Payload Compression Option

Configurable on a per route basis, payload compression can reduce the required satellite bandwidth by up to 40%.

Quality of Service (QoS) Option

The modems support multi-level QoS to reduce jitter and latency for real time traffic, provides priority treatment to mission critical applications and allows non-critical traffic to use the remaining bandwidth. Supported modes are:

 DiffServ – Industry-standard method of providing QoS enabling seamless co-existence in networks that implement DiffServ.

 Max/Priority – Provides eight levels of traffic prioritization with the ability to limit maximum traffic per priority class

 Min/Max – Provides a Committed Information Rate (CIR) to each user defined class of traffic with the ability to allow a higher burstable rate depending on availability

Vipersat Management System

 Dynamic SCPC carrier allocation & true bandwidth-on-demand

 User-defined policies for upstream carrier switching

 Star and full mesh capabilities using single hop on-demand

 Advanced switching takes advantage of using other modulation/forward error correction combinations

 Guaranteed bandwidth capability

VMS Network & Bandwidth Management

A Vipersat-powered network integrates these advanced modems with a powerful network management tool, the Vipersat Management

System (VMS). In addition to the traditional monitoring and control of the CDM-570/L-IP modems and the CDD-564/L and CDD-562L demodulators, the VMS allows these devices to share bandwidth, and when needed, switch automatically to a dedicated SCPC channel. In a Vipersat-powered network, the CDM-570/L-IP modem takes advantage of its fast acquisition demodulation to allow it to operate in a shared mode. Inbound transmissions (from remote to hub) can be switched from a shared Selective Time Division Multiple

Access (STDMA) mode to a dedicated Single Carrier Per Channel (SCPC) connection via a variety of user defined policies or triggers.

This enables the network to more effectively handle real-time connection-oriented applications and reduces both latency and network congestion. Through VMS, dynamic point-to-point mesh connections can also be established between remotes.

Upstream Switching

Through protocol classification in the remote terminals, the modem initiates automatic switching. VMS establishes dSCPC bandwidth based on policies that can be individually enabled on a per-remote basis, or globally enabled. Policies can be configured for a variety of applications such as VoIP, video (VTC), or based on a load, or via a schedule, Type of Service (ToS), or QoS rules such as IP port or

IP address and protocol type. Operators are able to set minimum and maximum data rates for each remote as well as excess data rates for an initial upstream switch.

Vipersat Operation Mode

Vipersat operation is enabled via a FAST feature code. Networks can easily start off in point-to-point or point-to-multipoint configurations. As the network grows and users wish to take advantage of the bandwidth on-demand savings by implementing a

Vipersat network, modems can easily be upgraded to Vipersat mode. Vipersat mode provides for the ability to operate in the following modulation/FEC rates:

STDMA

QPSK, Rate 3/4 Turbo FEC – all STDMA modes

Data Rate Range: 64 kbps – 4.5 Mbps

BPSK, Rate 5/16 Turbo FEC – Entry Channel Mode only
