Meridian DECT Product - Technical Support Update
Purpose
The intention of this Newsflash is provide an update to issues described in the
previous DECT Newsflash issued in September 2002 (NF 37/2002 issue 2) and to
provide additional important information on the supportability of the Meridian DECT
Product.
This also brings to a close the EuroDAC DECT Task Force activity; ongoing there will
no longer be a weekly meeting for DECT issues.
C4010/4020 handsets
Latest version of the C4010/4020 handset firmware is 0.51K. The following issues
reported in the previous Newsflash are resolved with this software.
Issue Symptoms/Description

It has been reported that in some
instances a C4010/4020 handset keypad
will unlock itself, if locked. This issue
was addressed in handset firmware
release 0.51H
*74 key combination causes ‘out of
range’
This firmware prevents the key
combination *74 from causing the
handset to show ‘out of range’. The only
recovery in older firmware releases is to
remove/replace the batteries or press the
reset pin. This issue was addressed in
handset firmware release 0.51K
There are no known technical issues on handsets with 0.51K firmware. It is
recommended that any C4010/4020 handsets experiencing one of these faults must
be upgraded to the latest firmware. Only then if the fault is still not satisfactorily
resolved for your specific customer please raise a case with Nortel.
C4050 Handsets
Latest version of the C4050 handset firmware is;
Flash 11-03-24
EEPROM 25-11
This firmware version contains the following updates
• Resolves problem entering name and number in the Telephone Book when
French language is selected
• Optimises Mute Parameter to reduce loud noise whilst on a call
• Improved handoff algorithm to reduce noise and failed handoff especially in
reflective radio environments
• Repeat Location Registration to prevent handset lockup
• Improvements to Handsfree performance
• Delete unwanted time display
• Corrections to display text in some languages
It is recommended that any C4050 handsets experiencing faults must be upgraded to
the latest firmware. Only then if the fault is still not satisfactorily resolved for your
specific customer please raise a case with Nortel.

DMC Card Software
Latest version of software for the DMC cards are;
DMC8 47000207
DMC4 45100207
These latest software versions address the following issues
DMC card lockup Symptoms would be no dial tone, unable
to receive or make calls on DECT hand
sets. The only recovery in older software
releases was to reseat or reboot the
cards
Base station lockup The base station appears to functioning
correctly, although there is no radio
signal. The only recovery in older
software releases was disconnect the
base station
IDC Command An issue reported for DMC8 cards on
larger systems; the IDC command can
return incorrect information
XMI001/002 messages An issue reported for DMC8 cards where
XMI001 quickly followed by XMI002
messages are seen
This software version also shows radio improvements for systems installed in
reflective environments.
It is recommended that any DECT systems experiencing these faults must have the
DMC cards upgraded to the latest software. It should be noted that these software
versions are only produced for OTM based systems. Only then if the fault is still not
satisfactorily resolved for your specific customer please raise a case with Nortel.
Non-Concentration on DECT
It is recommended to upgrade to Concentration Mode if investigating DECT problems
on X11 software version 25.15 or greater. Upgrading from Non-Concentration to
Concentration Mode is straight forward - run the CDCS command in overlay 10.
There are no side effects with this configuration change.

Serviceability on DECT
We are pleased to announce to some recent initiatives, which greatly improve the
serviceability of the Meridian DECT product.
DMC-8 Card Message Monitor/Debug Guide
This document details the message monitor capabilities on the DMC 8 card, which is
an important aid in identifying which part of the system architecture is involved in a
particular scenario and therefore to assist understanding and resolving problems on
MDECT.
DECT Concentration (DCS) X11 Software Monitor
This is an X11 monitor patch the purpose of which is to ensure that every message
that is sent between the X11 software and all DMC cards is a valid message, and
that the DCS handset is in the correct state to transmit or receive the message. If
required for fault analysis it should be requested from NTS
DECT Performance Manager
The DECT Performance Manager is available for download from the EMEA TSC
website. It is an application developed specifically to help with problem investigation
into areas including deployment, engineering, configuration, traffic etc. The
application is also capable of generating reports and trends on many differing
aspects of the system performance.
Conclusion
In conclusion, many issues have been resolved through the latest DMC software, the
new firmware for the C4010/4020/4050 handsets, and M1 DECT Service Packs for
25.15 and 25.40/B. It is imperative that before reporting faults to Nortel that these
solutions are employed in order to minimize unnecessary escalations. Below are the
updated details of these solutions.
