| Typical Application |
I. Here the Mega-T uses
four T1 lines to create a high-speed 6.112 channel for
a LAN internet-working application. The public network
can be accessed directly through T1 access lines, as
shown, or through an M13 router and T3 access line.
The Mega-E creates a high-speed access channel for E1
networks.
|
II. The Mega-T 241
transport E1 traffic over two T1 lines to extend an
E1 circuit across aT1 network, or connect an E1 multiplexer,
channel bank, or PBX directly to a public or private
T1 network.
