Note 1: The Siemens EWSD offers PRI support via both a National ISDN (Bellcore) and an AT&T "Custom" implementation. The above information pertains to the "Custom" implementation only (NTI has no National ISDN support). Although this interface is based on the AT&T 5ESS, NEC products have not been tested on the EWSD. Please contact NEC Product Management for any potential sales requiring PRI connection via the EWSD "Custom" interface.

Note 2: Support for Operator Access by the AT&T and NTI systems are realized in different ways. The NEAX2000 supports the AT&T implementation.
