50 Pair Punchblock
The 50 pair punchblock is the main interface point for RGPS, span lines,
customer I/O, Power Cabinet alarm lines, and the modem. The
punchblock provides primary protection for all lines. Refer to
Figure H-18 and Table H-4 for punchblock pin-out.
CAUTION
SC4812ET Span Line Labeling for Span B and Span C is
swapped
- On the SC4812ET’s, the span cabel internal to the base station
that connects the 50 pin header on the I/O plate to the CSU has
Span B and Span C (RJ-45) connectors mis-labeled.
- CFE will punch down the span on the 50 pair bunchblock as
per Motorola documentation and punchdown chart. When con-
ecting the span input to the CSU re-label “Span B” cable
to”Span C” cable to “Span B”. Connect to CSU as per docu-
mentation
- Note: The labeling issue on the cable from the I/O plate to the
CSU Part Number 3086601H01 Rev C shall be corrected on
revision “D” to address this issue. The cut over date to Rev. D
will be approximately January 30, 2001.
