features.
1.1.1

PSTN to H.323 Interworking

The Mediant 1000 H.323 gateway supports various ISDN PRI protocols such as EuroISDN,
North American NI2, Lucent 4/5ESS, Nortel DMS100, Meridian 1 DMS100, Japan J1, as
well as QSIG (basic call). 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, it 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 Mediant 1000 simultaneously supports different variants of CAS and PRI protocols on
different E1/T1 spans (no more than four simultaneous PRI variants).
PSTN to H.323 and H.323 to PSTN Called and Calling numbers can be optionally modified
according to number manipulation rules, including also modification of Numbering Type
and Numbering Plan.
The supported interworking features include the following:
Definition and use of Trunk Groups for routing IP PSTN calls.
B-channel negotiation for PRI spans.
ISDN Non Facility Associated Signaling (NFAS).
PRI to H.323 Interworking of Q.931 Display (Calling name) information element.

Supports sending trunk ID and B-channel number in H.323 Setup and Proceeding
messages (in the non-standard part).
