Sub-Mux capability can be used with the IP Packet Processor to multiplex a primary serial
synchronous or G.703 traffic stream with IP.
L.2.5 FAST Options
• Chapter 5. FAST ACTIVATION PROCEDURE
• Sect. 6.2.8 SELECT: FAST Menus (Chapter 6. FRONT PANEL OPERATION)
If there is a need to upgrade the CDM-625A IP Packet Processor’s functionality, Comtech EF Data
provides Fully Accessible System Topology (FAST), a technology that permits the purchase and
installation of options through special authorization codes. These unique Fast Access Codes may
be purchased from Comtech EF Data during normal business hours, and then loaded into the
unit using the front panel keypad.
Contact Comtech EF Data Product Support to acquire the following available FAST options:
• Quality of Service (QoS)
• AES Encryption
• Header Compression:
o Up to 5 Mbps (CCM) / 1200 ksps (ACM) o Up to 10 Mbps (CCM) / 4100 ksps (ACM)
o Up to 15 Mbps (CCM) / 4100 ksps (ACM) o Up to 20 Mbps (CCM) / 4100 ksps (ACM)
o Up to 25 Mbps (CCM) / 4100 ksps (ACM)
• Payload Compression:
o Up to 5 Mbps (CCM) / 1200 ksps (ACM) o Up to 10 Mbps (CCM) / 4100 ksps (ACM)
o Up to 15 Mbps (CCM) / 4100 ksps (ACM) o Up to 20 Mbps (CCM) / 4100 ksps (ACM)
o Up to 25 Mbps (CCM) / 4100 ksps (ACM)
L.2.5.1 Advanced Quality of Service (QoS)
The IP Packet Processor incorporates multi-level QoS to ensure the highest quality of service
with minimal jitter and latency for real-time traffic, priority treatment of mission critical
applications and maximum bandwidth efficiency.
The supported modes of QoS are:
• DiffServ – Industry-standard method of providing QoS, enabling seamless co-existence in
networks that implement DiffServ
• Max/Priority – Provides multi-level 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
