Connect the T1 Lines
The primary feature of the TNE1520 is loop bonding capability, although both the
provider and subscriber units are able to function with a single T1 connection.
Loop Bonded Connection
Using two T1 lines for one network connection (loop bonding) will net twice the speed
and data passing capability as a single T1 connection. A second T1 line also provides
backup should one of the lines become disabled. A TNE1520 can only establish loop
bonded connections with other Paradyne loop bonding-capable T1 equipment. See
Product to Product SDSL Loop Bonding Capability
(document number
COMP-A2-GK42).
Procedure
To establish a loop bonding connection:
1.
Plug the T1 cables into the T1 RJ45 ports (Port 1 and Port 2) on the back of the
TNE1520; the order of connection is not important.
2.
Verify both connections: the Port 1 and Port 2 Lnk LEDs on the front of the
TNE1520 will pulse green to indicate the connections are established and
operational.
Single T1 Connection
A single line connection can be established between a TNE1520-P and any of
Paradyne's T1 subscriber units, regardless of loop bonding capability. Likewise, a single
line connection can also be established between an TNE1520-S and any of Paradyne's
T1 provider units, regardless of loop bonding capability.
Procedure
To establish a single-line connection:
1.
Plug the T1 cable into one of the two T1 RJ45 ports on the back of the TNE1520;
either port (Port 1 or Port 2) may be used.
2.
Verify the connection: the T1 link LED on the front of the TNE1520 (Port 1 Lnk or
Port 2 Lnk depending upon which port was connected) will pulse green to indicate
the connection is established and operational.
If you are using a shielded T1 cable for your network connection, it must be grounded
through pins 3, 6, 7 and 8.
