for voice, data, video and LAN applications
OTN provides pre-allocated services for applications
OTN is a distributed system allowing dynamic switching for video
and audio
OTN has built-in redundancy
OTN is not a bandwidth on demand, but dedicated bandwidth at all
times regards of system loading.
OTN is not protocol, but rather physically oriented to best integrate
easily with applications equipment
OTN provides the best features of TDM and Ethernet in the same
product platform

Like a private superhighway
That never goes down
Never goes out of date
Never gets in the way
Spans any distance
Hooks up what you like
Takes a day to install
Is child’s play to manage
And easy to afford
