exit and then reenter this screen to ensure that all the

parameters have been updated.

T1-DTE Framing: Selects the type of framing for the

DTE side of the element. The choices are [ESF] and [D4

T1-DTE Line Code: Sets the DTE side line coding. The

choices are [AMI

] and [B8ZS].

T1-DTE DSX Level: Specifies the DTE line build out sig-

nal level. The choices are: ‘0-110

ft’

‘111-220ft’‘221-330ft’‘331-440ft’

‘441-550ft’‘551-660ft’‘>660 ft’

D/I Start Channel: Selects the first channel in the block of

channels assigned to the T1 DTE, from ‘1’ through ‘24’.

# of Channels: Sets the number of channels to be passed

through to the T1 DTE, from ‘1’ through ‘24’.

Channel Allocation: This display 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 num-

ber (1, 2, 3, or 4). Channels assigned to the T1 DTE are

marked as ‘D’. Non-assigned idle channels are marked with

a dash ‘-’. Remote communication channels are marked

with an ‘R’. When channels are assigned to a port in the

‘ALTERNATE’ assignment mode (see Section 4.6.3), each

data channel is followed by an idle channel that is not

assignable for other ports and is marked with an ‘x’.

4.6.2 Alarm Parameters

The ‘Alarm Parameters’ screen (Screen 4-7) allows the user

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.

NOTE: If alarm thresholds are edited from the front

panel, the corresponding values are not reflected on

this screen until it is exited and then reentered.

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.

DTE LOS/LOF Seconds: A one second period in which

the T1 received signal (on the optional T1 DTE interface) is

interrupted or the amplitude drops below a certain level.

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: A one second period in which 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.

Alarm Reset Timer: Determines the number of seconds

after alarm conditions clear before indications are removed.
