Position of the PRI Gateway in the Communication Server 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 a Media Gateway 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
