NORTEL TN-1X
Flexible, Managed SDH Multiplexers
Nortel’s Managed TN-1X
Multiplexer
The Nortel TN-1X is a highly
developed and effective SDH
fibre transmission system, which
provides an ultra-flexible base for
network applications.
• Short haul (1310) and long haul
(1550) optical ports and STM-1
electrical ports
This STM-1/4 network element
can be provisioned for 2-155Mbit/s
terminal multiplexing and add/drop
multiplexing. In addition to these
core functions the TN-1X’s vast
array of plug-in cards provides
greater flexibility plus the ability to
handle data.
• Flexible architecture allows
Terminal Multiplexer (TM),
regenerator, and Add/Drop
Multiplexer (ADM)
configurations
The TN-1X hardware consists of a
standard common shelf and
backplane and a range of optical
and electrical plug-in units,
including tributaries and
aggregates. Full mixing of tribs and
aggregates allows the optimum mix
for applications.
• 75 and 120 ohm 2 Mbit/s ports
The TN-1X has field proven
reliability based on:
• Experience, with over 25,000
synchronous elements deployed
worldwide
• Automated remote software
download
• In service upgrade
• Integrated Network
Management to contain whole
life costs
Features of the TN-1X
• Point and click end path
management system
• Remote software download
• STM-1/4 optical aggregate port
• 34 Mbit/s / 45 Mbit/s
(VC12/ VC3)
• Aggregate and Tributary
protection (Path Protection
and N+1)
• Class B EMC compliant
TN-1X Attributes
• Flexible architecture has
enabled the TN-1X to
address all STM-1 network
applications in providing:
- transport rings
- access to customer sites
- space efficient multiplexers
• The TN-1X fully inter-works
with the TN-1P and TN-1C
for customer premises
applications
• A proven and integrated
upgrade strategy enables
seamless feature additions
• G.826 Performance Monitoring
• Integrated and scalable
network management up to
10,000 network elements
from a single platform
• Portable Computer (PC)
terminal, for local configuration
and test facilities
• Simplified network planning,
management and installation
procedures
Added value provided through
Network Management
• In service upgrade path to
STM-4 line rates as traffic
demand increases
• Engineering Order Wire (EOW)
• External alarm inputs
Surveillance and control is
provided through Nortel’s
Integrated Network Management
System (INM), where up to
10,000 network elements can be
controlled from a single screen.
The Nortel low capacity SDH
family of products provides
seamless network control directly
into both residential and business
premises. The Nortel low capacity
SDH product range under the
Management System allows
network operators the opportunity
to integrate their entire
transmission network into an SDH
management system.
