CDM-570-IPEN & CDM-570L-
IPEN Satellite Modems
INTRODUCTION
The CDM-570-IPEN and the CDM-570L-IPEN are IP-centric
satellite modems with data encryption that provide industry
leading performance and flexibility in a 1 RU package.
With their innovative architecture and support for advanced
capabilities, CDM-570-IPEN and CDM-570L-IPEN allow for
efficient IP networking and transport over satellite links while
supporting a wide range of applications and network topologies.
In addition to the 10/100Base-T Ethernet interface, a wide range
of data interfaces are available to support legacy applications
and assist in migrating from legacy to IP transport.
They are the platform of choice for enterprise users, Internet
service providers, satellite service providers, offshore and
maritime users and mobile operators for a wide range of
applications – communication-on-the-move, disaster recovery
and emergency communications, enterprise, satellite news
gathering, offshore and maritime communications and cellular
backhaul.
The advanced FPGA-based architecture along with the internal
Flash memory allows for easy field upgrades via the Ethernet
port.
For cellular backhaul, the CDM-570-IPEN and CDM-570L-IPEN
also offer E1 RAN Optimization as an option.

INTEGRATED IP CAPABILITY
With its innovative architecture and support for advanced
capabilities, CDM-570/L-IPEN allows for efficient IP networking
and transport over satellite. CDM-570/L-IPEN supports a wide
range of applications and network topologies.
DATA ENCRYPTION
Configurable on a per route basis, the modem supports 3xDES
data encryption for transmission security to prevent unauthorized
access to data transmitted over the satellite link
.
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 modem supports 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 8 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
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.
