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:

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
