System configurations
The CS 1000 Media Gateway 1000E (MG 1000E) uses Media Gateway
Controllers (MGC) and DSP daughterboards (DSP DB) along with
CE-MUX cards to support PRI digital trunks. For each MG 1000E chassis,
an IPE shelf configuration supporting only one E1/T1 span for each card
along with one D-channel (DCH) daughterboard (for each slot) and one
clock controller daughterboard is used.
The PRI Gateway uses the MGCr with its DSP DBs along with an E1/T1
card that supports four to eight E1/T1 spans with up to four downloadable
D-channel (DDCH) daughterboards. This configuration supports any PRI
protocol variant in the CS 1000E system.
As shown in
Figure 3 "PRI Gateway configuration" (page 29)
, the PRI
Gateway replaces the MG 1000E as a PRI/PRI2 digital trunk gateway.
