Overview of the PRI Gateway
Figure 2: Position of the PRI Gateway in the CS 1000E system
The PRI Gateway supports four E1/T1 spans that can be expanded to eight E1/T1 spans. In
addition, the PRI Gateway:
• emulates and is configured as an Avaya CS 1000 Media Gateway 1000E (Avaya MG
1000E)
• is fully compliant with the E1/T1 alarms and Integrated Services Digital Network (ISDN)
protocols of the CE-MUX card
• uses one downloadable D-channel daughterboard to serve two E1/T1 spans
• has onboard clock reference functionality (eliminates the need for a clock controller
daughterboard), which is system-software transparent
• supports full flexible configuration so that:
- each of the E1/T1 spans in the PRI Gateway can be configured as E1 or T1
- multicountry E1/T1 ISDN protocols can be configured for each span; each E1/T1
span can be configured with any PRI protocol variant or interface type, for example,
DPNSS, Euro ISDN, NI2, MCDN
• has optional onboard implementation of DASS and DPNSS functionality
