switch supports Euro-ISDN PRI over E1, as specified in ETS TBR4 (ETSI’s European
Telecommunications Standard, Technical Basis for Regulation, TBR4).
NOTE In France, be sure to order Euro-ISDN signaling and not the older VN signaling.
T1 PRI
In Hong Kong, the ShoreGear-T1 supports the Hong Kong Telecommunications
Authority PRI standard HKTA2027, which is a 1.544Mbps T1 basic layer with ANSI-
based ISDN PRI higher layers (basically equivalent to what is used in the US).
International Telephones
Standard analog telephones are supported on a per-country basis. The main difference
between telephones in different countries is the line impedance. The ShoreWare
Distributed Call Control software will provide the appropriate impedance matching for
each supported country.
Tones, Cadences, and Impedances

per-country basis.
