Viewing T1/E1 Configuration and Alarm Information
Page 33-15
Viewing Information For an E1 Port
To view E1 port parameters, enter the following command
tes <slot>/<port>
where
<slot>
is the slot number where the board is located, and
<port>
is the E1 port number
on the board for which you want to view information. For example, to view information for
Port 2 on the board in slot 4, enter
Port 2 on the board in slot 4, enter
tes 4/2
A screen similar to following displays for an
E1
port:
T1/E1 Port Status for slot 4, port 2

Generation.
These parameters are described in the section, Configuring an E1 Port on page
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. Loopback modes are described in Configuring an E1 Port on page 33-8.
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
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 the port detects more than 10 consecutive zeros.
Line Code Violation Events
. The occurrence of either a bipolar violation or excessive zeros error.
A bipolar violation is the occurrence of a pulse of the same polarity as the previous pulse. In
HDB3
coded signals, a bipolar violation is a pulse of the same polarity as the previous with-
out being part of the zero substitution code. An excessive zeros error is the occurrence of
more than 15 contiguous zeros in an
more than 15 contiguous zeros in an
AMI
-coded signal; in an
HDB3
-coded signal, it is the
occurrence of seven (7) or more contiguous zeros.
