Nortel Networks NN43001-106 - Manual (Page 501)

Operating parameters 501
These new port types reside on the international IPE cards with flexible B34
firmware and the B34 codec. They have to be distinguished from existing
port types because of the different manner in which they are informed of the
base level/alternative level information.
Operating parameters
A system must be configured with one or more IPE card equipped with
a B34 codec and firmware supporting software downloading. It is the
responsibility of the installer to verify that the IPE cards used are compliant
with the download messages used by this feature.
The B34 Codec Static Loss Plan Downloading feature must be equipped,
since the B34 Dynamic Loss Switching feature uses its base level table.
Since the flexible 8B B34 equipped cards are not backwards compatible to
systems running older versions of software, the following upgrade strategy
should be followed:
• Systems running software Phase 7C or earlier, and upgrading to
Phase 8B software, do not require the new flexible B34 IPE cards
if the transmission plan remains the same. These systems may be
equipped with a mix of hardcoded B34 IPE cards and new flexible
B34 IPE cards; if changing to the new European Telecommunications
Standards Institute (ETSI) loss plan, all hardcoded B34 IPE cards must
be retrofitted with the new flexible B34 IPE cards.
• Systems changing to a new ETSI loss plan must use the new flexible
B34 IPE cards as well as Phase 8B static parameter download software;
a hardware retrofit and a software upgrade are also necessary.
• Newly installed systems will use the new flexible B34 IPE cards.
XFALC (Flexible Analog Line Card) is compatible with the download
messages supporting Static Loss Plan Downloading. XFALC is not
supported in Dynamic Loss Switching.
Connection matrixes are supported for Australia, New Zealand, and Italy.
No other countries are supported with this feature.
New flexible B34 equipped XFALC (flexible analog line cards) support Static
Loss Plan Downloading using B34 messages. New flexible B34 equipped
XFALCs installed in a Phase 7C software environment do not receive
download messages, but use the firmware-defined default.
A distinction must be made between long and short lines on Analog Line
Cards (ALC), and to download loss plan values based on this setting.
