Benefits
The ONS150 provides the following benefits:
- cost-effective, easy-to-use digital
access for a variety of T1/FT1 applications – this
maximizes networking budgets and saves time
- proven technology as evidenced by
the thousands of ONS150s installed – this ensures
reliable operation and network availability
- flexible diagnostics enable timely
resolution of network problems – this maximizes
network uptime
- a variety of available interfaces – V.35, RS-449
or RS-530 – makes it easy for network administrators
to use existing cables – this maximizes network
investment and saves money
- plug-and-play operation setup is
accomplished completely by a dipswitch – this
minimizes installation and training time
Applications
- The ONS150 is used in point-to-point T1 or FT1 applications
to provide cost-effective access to digital networks
and frame relay services.
- The ONS150 is also ideal for small to medium-sized
networks that require T1 or FT1 access at the remote
sites.
