SUMMARY: Use this procedure to convert feature package B (FPB) [with AUB27
alarm display unit (ADU)] Mode 1 or Mode 2 to feature package 303 (FP303). The A
and C line interface unit (LIU) DS1 facilities carry the active and standby embedded
operations channel (EOC) and timeslot management channel (TMC) in a FP303
system; therefore, the minimum system must include both of these facilities.
!
CAUTION:
FP303 does not support non-switched and non-locally
switched special services; therefore, these services must be
moved to another system before starting this procedure.
This conversion requires coordination between the RT craft and the
5ESS IDCU
personnel. The RT craftsperson follows this procedure while the switch person
follows 235-105-210, Procedure 9.91.

CAUTION:
An electrostatic discharge wrist strap with a minimum
resistance of 250K Ohms should be worn when handling
Series 5 circuit packs to prevent possible damage to the
circuit packs. Before using the wrist strap, check it for
opens, shorts, and minimum resistance value. If the strap
does not pass these checks it should not be used. To avoid
possible personal injury while using the wrist strap, do not
connect it to the power shelf or adjacent portions of the RT
frame. Connect the wrist strap to ESD GRD jack on the fan
unit, if present. If grounding jack is not present, connect
wrist strap to bare-metal section of the frame well away from
the power shelf.
