1303 FAIL The DS1 circuit pack Suffix is incorrect for CSU Module 
administration. The 
Near-End CSU Type
 field on the 
add 
ds1
 form has been administered as 
integrated
 but the 
DS1 circuit pack is not a TN464F or later suffix UDS1 
board. 
1. If the CSU Module is to be used, and the 
Near-End 
CSU
 type field is set to 
intergrated
 to allow for CSU 
Module administration, remove the circuit pack and 
replace with a TN464F or later suffix board. 
Otherwise, use the 
change ds1
 command to 
change the 
Near-End CSU Type
 field to 
other
.
1310 FAIL The DS1 Board Loopback (BLB) demand test (#1209) 
failed.
1. Repeat the test using the 
test ds1-loop PCSS 
ds1/csu-loopback-tests
 command.
2. If the BLB test continues to fail, then replace the 
TN464F circuit pack. 3) Run this test again.
