Overview of the PRI Gateway
CE-MUX support
The E1/T1 card supports the CE-MUX interface from the MGC for up to
eight PRI spans. The new E1/T1 card added into this PRI Gateway in CS
1000 Release 5.0 emulates the CE-MUX cards (NTAK09 and NTBK50AA).
Table 4 "CE-MUX daughterboards supported by the E1/T1 card" (page
30)
shows the D-channel daughterboards that are supported by the E1/T1
card and its expansion.

ATTENTION
The PRI Gateway eliminates the need for a clock controller daughterboard. The
clock controller functionality is provided internally.
Shelf slot assignments
The PRI Gateway chassis has two physical backplane slots: one for the
MGC with its DSP daughterboards and the other for the new E1/T1 card
and its expansion daughterboards.
The E1/T1 card emulates an MG 1000E with eight CE-MUX PRI/PRI2
cards, supported in card positions 1 to 8 with DSPs using a total of 16 slot
assignments.
Table 5 "Shelf slot assignments" (page 31)
describes the 16 slot
assignments and their mapping.
