Appendix L. IP PACKET
PROCESSOR OPTION
L.1 Overview
The IP Packet Processor is an optional feature for the CDM-625A Advanced Satellite Modem. In
addition to providing Layer 3 functionality, it incorporates a number of key features for Wide
Area Network (WAN) bandwidth optimization. This includes very low overhead Streamline
Encapsulation (SLE), Header Compression, Payload Compression, Advanced Quality of Service
(QoS), and Advanced Encryption Standard (AES) Encryption.
The IP Packet Processor enables efficient IP networking and transport over satellite either in
Router Mode or Managed Switch Mode. The combination of Advanced QoS with Header and
Payload Compression ensures the highest quality of service with minimal jitter and latency for
real-time traffic, priority treatment of mission critical applications, and maximum bandwidth
efficiency.
L.1.1 Operational Requirements
The IP Packet Processor is available as a factory-installed option or, depending on
its originally shipped configuration, as a field-upgradeable option. Use of the IP
Packet Processor with the CDM-625A Advanced Satellite Modem requires the
following:
CDM-625A Power Requirements for the IP Packet Processor Board (CEFD P/N
PL-0000481) – When ordering the IP Packet Processor as a factory installed option,
the modem power supply that is specified at the time of order must be 175 watts
for AC units, or 125 watts for DC units.
Existing field units that meet either power supply configuration requirement are
user-upgradable in the field using CEFD Kit KT-0000176 – refer to Section L.5 in
this appendix for the field upgrade procedure using this kit.
However, existing field units that do not meet these power supply configuration
requirements – i.e., units that are configured with 65W AC or 65W DC power
supplies – must be returned either to Comtech EF Data or sent to a Comtech EF
Data Authorized Service Center for upgrade using CEFD Kit KT-0000174 (for 65W
AC units) or CEFD Kit KT-0000175 (for 65W DC units).
