Viewing Information For a T1 Port
To view T1 port parameters, enter the following command
tes <slot>/<port>
where
<slot>
is the slot number where the board is located, and
<port>
is the T1 port number
on the board on which you want to view information. For example, to view information for
Port 2 on the board in slot 5, enter
tes 5/2
A screen similar to following displays for a
T1
port:

These parameters are described in the section,
Configuring a T1 Port on page 33-4. Please refer to that section for descriptions.
Status Change Time
. The system time when the last change in Line Status (i.e., alarm) parame-
ter occurred.
Loopback Status
. The type of loopback mode configured for this port through the
temod
command or activated remotely through
FDL
. Loopback modes are described in Configuring a
T1 Port on page 33-4.
Line Status
. A list of any alarms that have occurred on his port. The possible items in the list
are the same as those for
Active Alarms
described in Viewing Information for all T1/E1 Ports in
the Switch on page 33-11.
Loss of Signal Events
. The total number of Loss of Signal (
LOS
) events that have been detected
on this port. An
LOS
event occurs after 175 contiguous pulse positions with no pulses (10
absent pulses on
E1
ports). An
LOS
failure is cleared after the switch observes a single pulse.
Line Code Violation Events
. The occurrence of either a bipolar violation or an excessive zeros
error. A bipolar violation is the occurrence of a pulse of the same polarity as the previous
pulse. In
B8ZS
coded signals, a bipolar violation is a pulse of the same polarity as the previ-
ous without being part of the zero substitution code. An excessive zeros error is the occur-
rence of more than 15 contiguous zeros in an
AMI
-coded signal; in a
B8ZS
-coded signal, it is
the occurrence of seven (7) or more contiguous zeros.
