Configuration 3-11 PRISM 3101/3102
T1-DTE Line Code: Sets the network side line coding as
either AMI or B8ZS.
T1-DTE DSX Level: Specifies the DTE line build-out sig-
nal level as either 0-110 ft, 111-220 ft, 221-330 ft, 331-440
ft, 441-550 ft, 551-660 ft, or >660 ft.
T1-DTE Channel: Selects channels to be assigned to the
T1/DTE from 1 through 24.
Settings:Selects the channel to be either IDLE or THRU.
Channel Allocation: This display-only field indicates the
network channel assignments with Channel 1 on the left and
Channel 24 on the right. Channels assigned to a port are
identified with a port number (1 or 2). Non-assigned idle
channels are marked with a dash (-). Remote communica-
tion channels are marked with an R. T1-DTE channels are
marked with a D.
A LARM C ONFIGURATION
The Alarm Configuration screen (Figure 3-12) allows you
to review and set alarm related thresholds for the selected
element. These thresholds are the minimum acceptable per-
formance levels. To modify the parameters, highlight the
desired statistic, type in the new value (any number from 0
to 900) and press <return>. If this value is later surpassed,
an alarm indication will appear. A field set to (
0 ) will cause
the element not to alarm on that statistic.
Errored Seconds: A one second period in which at least
one logic error occurred.
Severely Errored Seconds: A one second period in which
at least 320 CRC errors or 1 OOF (out-of-frame) occurred.
Loss of Signal Seconds: A one second period in which the
T1 received signal is interrupted.
Unavailable Seconds: A one second period in which con-
secutive severely errored seconds cause an unavailable state.
Remote Alarm Seconds: Generated by the terminal equip-
ment when an improper signal is received from the facility
(or upon receipt of unframed all ones).
AIS Seconds: One second period when all ones are received.
Out of Frame Seconds: A one second period in which a
frame sync loss occurred.
BPV Seconds: A one second period in which at least one
bipolar violation occurred.
DTE LOS/OOF Seconds: A one second period where the
T1-DTE received signal frame synchronization is inter-
rupted or the amplitude drops below a certain level.
Alarm Reset Timer: Determines the number of seconds
after alarm conditions clear before indications are removed.
