SIP) and management (e.g., SNMP and Web) protocols.
1.2.2

PSTN-to-SIP Interworking

The Mediant 1000 Digital SIP gateway supports various ISDN PRI protocols such as
EuroISDN, North American NI2, Lucent 4/5ESS, Nortel DMS100, Meridian1 DMS100,
Japan J1, as well as QSIG. PRI support includes User Termination or Network Termination
side. ISDN-PRI protocols can be defined on an E1/T1 basis (i.e., different variants of PRI
are allowed on different E1/T1 spans).
In addition, the gateway supports numerous variants of CAS protocols for E1 and T1
spans, including MFCR2, E&M wink start, E&M immediate start, E&M delay dial/start, loop-
start, and ground start. CAS protocols can be defined on an E1/T1 basis (i.e., different
variants of CAS are allowed on different E1/T1 spans).
The gateway simultaneously supports different variants of CAS and PRI protocols on
different E1/T1 spans (no more than four simultaneous PRI variants).
PSTN to SIP and SIP to PSTN Called and Calling numbers can be optionally modified
according to rules that are defined in gateway's ini file.
