3.5 MEASUREMENTS FROM DIAGNOSTICS
A unit-based comparison of diagnostic measurements is provided in Table 13 .
Table 13: Comparison of diagnostic measurements
Measurement Description Availability Advantage Disadvantage
Bit errors Logic errors in
the bit stream Only out of
service Best unit for
point-to-point
performance Requires that all traffic
be test traffic (known
data pattern)
BPVs Pulses of the
same consecutive
polarity In service
or out of
service Good for circuit
or repeater
problems Meaningful for only
metallic media, because
some equipment corrects
BPVs
Frame errors Incorrect values
in the framing
bit position In service
or out of
service Approximates
bit error rate on
in-service basis Evaluates only overhead
bits
CRC errors Bit errors in a
block of data In service
or out of
service 98.4% bit error
rate accuracy Available with only ESF
framing
3.6 FIRMWARE UPGRADES
Firmware upgrades are periodically made available to enhance performance or to add
features and functionality to the Canopy T1/E1 Multiplexer.
Procedure 29: Upgrading firmware
To install new firmware on a Canopy T1/E1 Multiplexer, perform the following steps.
1. Close any other applications that are active on the PC.
2. From the main menu of the EMS, select Config →Software Upgrade (shown in
Figure 15 on Page 33 ).
RESULT: The System Upgrade window opens, as shown in Figure 24 .
