POS-3504As Module
•
POS-3504As OC-48, 1-port, single-mode module
•
POS-3505As OC-48, 1-port, single mode module
Module Type:
SmartMetrics Packet over SONET module.
Where Used:
SMB-600 and SMB-6000B.
Applications
Supported:
SmartWindow, SmartLib, SmartFlow, and ScriptCenter.
Devices Tested:
POS/SDH routers and networks.
Test Objective:
•
Evaluate and optimize hardware performance of POS routers under typical or extreme
load conditions.
•
Test IP Quality of Service performance including Diffserv and address-based
polocies.
•
Perform stress and negative testing using errored SONET/SDH frames.
Features:
•
OC-48cSTM-16 wire-rate traffic generation and analysis (approximately 6.5 million
frames per second).
•
Capable of generating back-to-back frames supported by a single flag.
•
SONET or SDH framing.
•
Each POS module supports one port on the SMB-600 or SMB-6000B chassis. Up to
two modules may be installed in the SMB-600 chassis. Up to twelve modules may be
installed in the SMB-6000B chassis.
•
SONET/SDH line analysis of, and error generation through, control of the Section
OverHead (SOH), Line OverHead (LOH), and Path OverHead (POH).
•
SONET/SDH payload scrambling enabled under user control (X
43
+1).
•
User-selectable Frame Check Sequence (FCS) of 16- or 32-bit.
•
IP traffic encapsulated over PPP (as per RFC 1662) or over Cisco’s HDLC with
Ethertype.
•
MPLS with static labels enables functional testing of routing hardware.
