PRELIMINARY
T1/E1 Span Interface
At active sites, the OMC–R/CBSC must disable the BTS
and place it out of service (OOS). DO NOT remove the
Span Line Cable Connectors until the OMC–R/CBSC has
disabled the BTS.
NOTE
Before connecting the LMF Computer to the BTS Frame LAN, the
OMC–R/CBSC must disable the BTS and place it OOS. This will allow
the LMF to control the BTS, and prevent the CBSC from inadvertently
sending Control Information to the BTS during LMF–based Tests.
Isolate the BTS from the T1/E1
Span(s)
Once the OMC–R/CBSC has disabled the BTS, the Span(s) must be
disabled to ensure the LMF will maintain control of the BTS. To disable
the Spans, disconnect the BTS–to–CBSC Transcoder Span Cable
Connectors from the Span I/O Cards (Figure 3-2).
