3.10 You can set the thresholds (number per hour and number per day) for T1/E1/PRI or BRI
errors, if necessary. (These are set to default values that, in most cases, will not need to be
changed.) Possible errors include the following:

B. REFERENCE CLOCK LIST
3.12 One T1 or E1 card is designated as the "Slave from Public Network" and is the system
reference card. All other cards are the backup cards.
3.13 The reference clock list has three categories that determine whether the card is a master
or a slave and if it is in a public network or a private network. They are:
•

•
3.14 All cards configured in the system appear in this window. Place the cards in the proper
categories by clicking on their Value and scrolling the list box to the proper setting.
NOTE:
the master dual-chassis.
3.15 If there is more than one "Slaves from Public Network," the first card is the system ref-
erence card. The other cards that appear below it in the list are the backup cards (in the order
they appear in the window).

MANUAL VERSION 11.0 – May 2008
Specifications include several error thresholds. When an error exceeds one of these
BPV (Bipolar Violations): This is a non-zero signal element that has the same polarity
as the previously received non-zero element.
CRC-6 (Cyclic Redundancy Check): (T1/E1/PRI Only) The calculation carried out on
a set of transmitted bits by the transmitter does not match the calculation performed by
the System.
OOF/COFA (Out of Frame/Change of Frame Adjustment): (T1/E1/PRI Only) OOF
is a state in which the frame alignment that is received is not consistent with that which
is transmitted. COFA occurs when the System realigns its receiver to the proper frame
alignment signal. This could be caused by an incorrect line build-out (LBO) value.
CS (Controlled Slips): (T1/E1/PRI Only) The System replicated or deleted one 192-bit
digital signal (DS1) frame due to a lack of frequency synchronization. This could be
caused by an incorrect line build-out (LBO) value.
ES (Errored Seconds): These are seconds in which at least one error occurred.
SES (Severely Errored Seconds): This is a second during which transmission perfor-
mance is degraded below an acceptable level.
UAS (Unavailable Seconds): (T1/E1/PRI Only) This is the time interval during which
the T1 or E1/PRI span is unavailable for service. This time begins with 10 or more con-
secutive Severely Errored Seconds and ends with 10 or more Non-Severely Errored
Seconds.
