T1 Line Length
Set the line length for each T1 interface according to the distance
from the MX2800 STS-1 to your DTE device. Set to
-7.5
D
B
if the
attached DTE device only supports DS1 levels.
T1 Remote Loopback
Allows a selected T1 to respond to CSU or NIU loopbacks arriving
from the STS-1 side.
T1 Circuit Protection
T1 Circuit Protection determines which circuit will be allowed to
initiate a protection switch if a failure in the circuitry for that
channel is detected. If a T1 is set to
D
ISABLED
, then the failure of the
circuitry of that one channel will not cause a protection switch. If
set to
E
NABLED
, then the failure of a channel
could
cause a
protection switch to occur (depending on the
P
ROTECTION
T
HRESHOLD
setting).
Hairpin Loopback
Hairpin back the VT to the STS-1 signal for dropping farther down
the SONET ring.
Line ID
Enter user-configurable text strings to name the individual T1 lines.
This field will accept up to 18 alpha-numeric characters, including
spaces and special characters (such as an underbar).
Set Multiple
S
ET
M
ULTIPLE
(see Figure 3-6 on page 3-10) can be used to enable/
disable a contiguous group or all of the VTs at one time. It may also
be used to make multiple changes to the line coding, length, circuit
protection or loopback detection of a contiguous group or all VTs at
one time.
