Term or Abbreviation Definition
split backhaul Backhaul serving a network in which IS–95A/B traffic and 1X data traffic are
mixed on circuit backhaul from CDMA2000 1X BTSs. 1X data traffic is “split”
from IS–95A/B on a single span by being transported on DS0 time slots dedicated
to a “packet pipe.” IS–95A/B traffic is transported on the remaining DS0 time
slots. Split backhaul on a single span must be connected to a Digital Access and
Cross–connect System (DACS) which directs IS–95A/B traffic to the CBSC XC
and 1X data traffic to the Access Node (AN), as required. If a DACS is not used, a
CDMA2000 1X BTS must be equipped with separate spans for 1X data packet
and IS–95A/B voice/data traffic, respectively. The 1X data packet–dedicated span
would connect directly to the AN. The IS–95A/B–only span would connect
directly to the CBSC XC.

updated design frame +27 Vdc and –48 Vdc BTS frames that contain enhancements of the BTS product
and include starter and expansion frames. The FE Housing present on these
frames is located in the front middle of the top I/O panel. Both the +27 Vdc and
the –48Vdc frames are 1800mm (original –48 Vdc frames are 2100mm).Another
visual reference that helps determine the frame at the site is the location of the
circuit breakers. The updated design frame provides the cage circuit breakers in
the middle right section of the frame. Refer to the +27 Vdc or –48 Vdc
Differences sections for a visual explanation of original production frames.
