h. Error Type 769: transmit FIFO Underflow Error. This error occurs when the circuit pack cot
find the “end of frame” bit when transmitting a frame to the Packet bus. An alarm is raised if
this error occurs three times within 10 minutes. Clear the alarm using the following
commands: busyout board location, reset board location, test board
location long, release board location. If the error recurs within 10 minutes,
replace the circuit pack.
i. Error Type 770: unable to Write LAN Translation RAM Error. This error occurs when a call
is aborted because there are no available translation RAM locations for the call connection
attempt. An alarm is raised if this error occurs two times within 10 minutes. Clear the alarm
using the following commands: busyout board location, reset board location,
test board location long, release board location. If the error recurs within 10
minutes, replace the circuit pack.
j. Error Type 1300: CSU module/T1 sync splitter missing or E1 synchronization splitter
(E1SS) missing.
CSU module/T1 sync splitter missing: The Near-End CSU Type field on the add ds1
screen is integrated but the 120A1 CSU module or the 401A T1 sync splitter is not
physically connected (or is improperly connected) to the UDS1 board on the back of the
port carrier.
If using the 120A1 CSU module or the 401A T1 sync splitter, plug (or replug) the CSU
module/T1 sync splitter into the UDS1 circuit pack’s connector on the I/O connector panel
on back of the carrier. Otherwise, set the Near-End CSU Type field using the change
ds1 screen to other.
If this error remains after plugging the CSU module/T1 sync splitter into the board’s
connector, there could be a problem with the I/O connector panel.
E1 synchronization splitter missing: The E1 Sync-Splitter field on the add ds1
screen is y, but the 402A or 403A E1 synchronization splitter is not physically connected
(or is improperly connected) to the UDS1 board on the back of the port carrier.
If using the 402A or 403A E1 synchronization splitter, plug (or replug) the E1SS into the
UDS1 circuit pack’s connector on the I/O connector panel on back of the carrier.
Otherwise, set the E1 Sync-Splitter field using the change ds1 screen to n.
If this error remains after plugging the E1SS into the board’s connector, there could be a
problem with the I/O connector panel.
k. Error Type 1301: CSU module/T1 sync splitter not expected or E1 synchronization splitter
not expected.
CSU Module/T1 Sync Splitter not expected: The 120A1 CSU module or the 401A T1
sync splitter is physically connected to the UDS1 board on the back of the port carrier, but
the Near-End CSU Type field on the add ds1 screen is not set to integrated.
If the 120A1 CSU module or the 401A T1 sync splitter is to be used, use change ds1 to
set the Near-End CSU Type field to integrated. Otherwise, physically remove the 120A1
CSU module or the 401A T1 sync splitter from the back of the port carrier.
