Revision history
October 2003
Standard 1.00. This document is a new NTP for Succession 3.0. It was created
to support a restructuring of the Documentation Library, which resulted in the
merging of multiple legacy NTPs. This new document consolidates
information previously contained in the following legacy documents, now
retired:
•International Loss and Level (553-2201-181)
•Summary of Transmission Parameters (553-2201-182)
This document also contains a chapter “Succession Transmission
Parameters” that was previously found in Succession Communication Server
for Enterprise 1000 Planning and Engineering (553-3023-120).

System migration
When particular Meridian 1 systems are upgraded to run Succession 3.0
Software and configured to include a Succession Signaling Server, they
become Succession 1000M systems. Table 1 lists each Meridian 1 system
that supports an upgrade path to a Succession 1000M system.

Note the following:
• When an Option 11C system is upgraded to run Succession 3.0 Software,
that system becomes a Meridian 1 Option 11C Cabinet.
• When an Option 11C Mini system is upgraded to run Succession 3.0
Software, that system becomes a Meridian 1 Option 11C Chassis.

Introduction to Loss and Level
The system is capable of meeting transmission requirements worldwide.
Government agencies define the transmission requirements that all
equipment installed in that country must meet.
Configuring the system to meet country-specific requirements occurs during
installation. If changes to the transmission settings must occur after
installation, contact a Nortel Networks transmission specialist to help with
the changes.
In the system, an algorithm called the Loss and Level Plan controls the
port-to-port loss between two ports or the signal level at any given port, based
on the port types involved in the connection. This plan is country-specific;
therefore, within a given country, the plan controls the insertion and value of
pads necessary to comply with the loss and level requirements of that country.

Introduction
Peripheral Equipment (PE) cards meet a predetermined transmission level
standard. The insertion of a pad in the transmission path on the Intelligent
Peripheral Equipment (IPE) cards or the alteration of the card loss on Flexible
IPE cards changes the level.
Pads alter the power level of signals applied to them. Pads can either attenuate
or amplify the applied signal. The term “loss” means the pad attenuates the
signal. The term “gain” means the pad amplifies the signal. The use of pads
ensures the power level is within acceptable limits at the far end. Far end, in
this case, refers to the port to which the connection is established within the

PBX. Pads can be applied in both the transmit and receive directions of a
transmission path and the two pads are likely to be of different values.
With Flexible IPE cards using B34 codecs, level adjustments are achieved by
altering the card loss. The card loss acts in the same manner as a pad, that is,
it can provide gain or loss. This is achieved by scaling the digitized signal.
The following components have transmission adjustment capabilities:
• conference cards
• analog trunk cards
• digital trunk cards
• B34 codec-equipped International Intelligent Peripheral Equipment
(IPE) Extended Flexible Analog Line Cards (XFALC); Extended Central
Office Trunk Cards (XCOT), Extended Direct Inward Dial Cards
(XDID), and Extended Flexible E&M Cards (XFEM) in Australia, New
Zealand and Italy; Extended Universal Trunk cards for China (XUTC)
and XEMC in China
• Basic Rate Interface Line and Trunk application cards
• Meridian Modular Telephone sets
• Extended Off-premises Station (XOPS) line card
There are two approaches to loss settings. For non-flexible IPE cards, pad
values are hardcoded on the card and the required pad state is indicated by a
message sent to the card. The pads that are in or out for a particular connection
type are part of a predefined table. For flexible IPE cards, card losses are
definable through software (LD 97).
